With the pressure roller, tension rolls for the rewinding unit can prevent the strip from slipping on the surface of the rolls and get initial tension. <br> <br>BOYA Rewinding Line Features <br> <br>The force increase of tension roller unit was achieved by wrapping effect of each tension roll. <br> <br>In the condition of the rewinding line wrapped around a roll was affected by a certain initial tension, the friction force between them reached a maximum number and the transfer power outreached the maximum friction, there will be skidding between the strip of recoiling line and the roll surface. <br> <br>Automatic Sleeve Feeding arrangement system. <br> <br>Entry Flattener with Quick Opening Feature. <br> <br>Doctor blade to be provided for all entry/exit deflector rolls, bridle rolls, and turn rolls. <br> <br>The Coil car will have auto coil shuffling to move the coils up to saddle one. <br> <br>Full line canopy covers. <br> <br>The Belt Wrapper is designed in such a way that it will be suitable for under and recoiled. <br> <br>Tinplate and Carbon Steel. <br> <br>Trimming Speed: 720Mpm Leveling Speed: 600Mpm <br> <br>Rewinding Line Strengths <br> <br>The coil car will be lifted up to the collapsed mandrel So that we can easily unload small coils from the mandrel. <br> <br>Low pressure system to prevent damage when removing small coils. <br> <br>Improve the flatter efficiency. <br> <br>High precision and stable control system. <br> <br>Safety and reliable production process. <br> <br>Compact structure and easy maintenance, environmental protection. <br> <br>Rewinding Line Working Principle <br>01 <br>The recoiling line running speed also can affect the total friction between the strip and the roll surface. When the strip runs under a higher speed, the positive pressure of the strip on the roll surface is lower, and the gas passing between strip and roll surface in the entrance cannot be exited quickly, which can continue to accumulate with the increase of speed. Therefore, on the one hand, the actual wrap angle between the strip and the roll surface is reduced, on the other hand, the coefficient of friction between them is also diminished. Finally, all of them results in the decrease of the whole friction, which can be represent apparently under the poor incoming plate shape. In conditions of the same initial tension of tension roller unit, the entrance roller unit with a small force has a higher slip probability than the exit one with a higher force. <br> <br>02 <br>The slipping of any tension roll unit will cause scratches to the surface of the strip. In the rewinding line, the light damage can degrade product quality, while the heavy one will scrap the strip. So the slipping of the tension roll unit is extremely harmful to production. <br> <br>03 <br>At the same time, the slipping of any tension roll unit will have a direct effect on itself, which can make the roller surface smoother and smoother. The friction coefficient diminished rapidly, so we need to regrind the roll surface and the roll usage period will be shorted. In addition, the skidding of tension roller unit can cause motor output torque to fluctuate, impact the transfer decelerator, make gear failure and defect the decelerator. <br> <br>04 <br>In order to prevent slipping, rewinding line diameter is selected based on the principle that no plastic deformation occurs after the strip passed through the tension roller. The max thickness of coil processing line strip is the main factor to determine the max diameter of tension roller. The phenomenon that the slipping probability of cold-rolled thin strip steel is significantly increased under the large tension roll diameter. There should be a limit to the adaptation scope of strip, the diameter of tension roller is not the bigger the better. In order to add the friction coefficient as soon as possible, we need to increase the roughness of the roll surface. <br> <br>05 <br>Although we cannot eliminate the slipping of tension roll through the way of improve the electrical control of tension roller unit, we can provide the reasonable and perfect electrical control method which can benefit to diminish the degree of slippage. Therefore, we can decrease the wear of tension roll, and it is helpful for us to find and correct the slipping. <br> <br>If you want to know more details of stainless steel coil processing, please visit our website. <br> <br>Now the price of tension leveler is reasonable, if you are interested, please contact us.

BOYA takes targeted design according to customer demand, provides customized system solutions to customer from product research to product use and Q&amp;A training, help metallurgical enterprises transformation and upgrading! <br> <br>Why Burr Appears After Side Trimmer in Hot Rolling Pickling Line <br> <br>BOYA coil shearing machine is one of the key equipment of pickling line or PLTCM. The sheet cutting shearing machine function is to trim the edge of raw materials according to the width of finished products and remove the quality defects of raw materials .For example Burr refers to the raw material in the edge-cutting treatment, the appearance of &quot;hair-like&quot; quality defects at the edge of the strip. Its harm is that the burrs are easy to cause the strip broken in rolling process; A good cut can avoid defects such as burrs, which may cause quality problems during rolling. The main reasons for burrs are: <br> <br>Hot rolling raw material defects <br>Uneven width, edge wave, edge wrinkle, edge crack and other quality defects of hot rolling raw materials will impact the blade edge of the trimming, resulting in the blade edge collapse, or lead to the trimmer edge cutting failure or slip blade, resulting in burr <br> <br>The clearance calculation has changed <br>The shear Gap is determined by both Gap and Lap. The mathematical model used for clearance calculation is based on the theoretical cross-section of hot rolled material. The theoretical hot rolling material has good consistency of cross-section, few edge drop and no wedge. In fact, the cross-section structure of hot rolling materials used in cold rolling mills of various steel mills is not the same, and hot rolling materials have their own unique cross-section structure, so there is a deviation between theory and practice <br> <br>Clearance calibration is not accurate <br> <br>Trimming edge gap jump <br>The gap jump of the trimming edge is produced by the coordination of upper and lower cutting edges. The cutting edge is fixed on the shaft head of the cutting seat by the hydraulic nut, and the expansion ring is pressed outward by the locking screw. When the hydraulic nut is not properly fastened, the axial force is insufficient in the process of vertical strip cutting edge, resulting in the axial jitter of cutting edge and the jump of cutting edge gap. <br> <br>For more information about sheet shearing machine price and Tension leveling, please feel free to contact us! <br> <br>There are many metal processing machinery manufacturers, but we are one of the best choices for you.

Hydraulic nut is a strong fastening component, it is a special nut that integrates a hydraulic device on the nut body and locks the connecting object via liquid pressure. It changes the traditional torque locking to axial tensile locking. The hydraulic nut can be directly replaced the traditional nut for all kinds of occasions that need strong fastening and strong anti-loosening, especially in narrow spaces that can not meet the occasion of large spanner operation, installation and assembly work more accurately. <br> <br>Main Applications of Hydraulic Nut <br> <br>The blade axial locking of side trimmer, slitters and other metal slitting machine <br> <br>Inner and outer rings of precision bearings are locked <br> <br>Locking fixture for forming process <br> <br>Locking of large parts in the coal mine, shipbuilding, power generation, chemical industry, metallurgy and other industries <br> <br>Advantage of Hydraulic Nut <br>The body is divided into steel parts and aluminum parts, with a compact structure, high strength and strong reliability. <br> <br>Aluminum parts are lighter and lighter to use. <br> <br>A floating pressure ring can perfectly fit the brocade cotton, making the pressure uniform, high locking accuracy.

Click on the links below for more information! <br> <br>What is Metal Leveler Machine? <br>The so-called straightening machine sheet leveler machine is simply equipment for straightening metal profiles, bars, pipes, wires, etc. The working principle of this kind of metal forming machine is to change the straightness of bars etc. through the straightening rollers. Generally speaking, the leveler machine has two rows of straightening rollers, of course there are exceptions. The two-roll leveler machine usually straightens materials of different diameters by relying on the angle change of the two rolls. leveler machines can be divided into pressure leveler machines, balanced roll leveler machines, shoe roll leveler machines, rotary reverse bending leveler machines and so on. <br> <br>Straightening Process of Sheet Leveler Machine <br> <br>When the sheet leveler machine is working, the position of its rollers is at a certain angle with the direction of movement of the product to be straightened. Two or three large ones are active pressure rollers, which are driven by the motor to rotate in the same direction. Several small rollers on the other side are The driven pressure rollers are rotated by the friction of the rotating rod or tube. In order to achieve the required compression of the product by the rollers, these small rollers can be adjusted forward or backward at the same time or respectively. Generally, the more the number of rollers, the higher the accuracy of the product after straightening by sheet leveller. After the product is bitten by the roller, it continuously moves in a straight line or rotates, so that the product undergoes various deformations such as compression, bending, and flattening, and finally achieves the purpose of straightening. <br> <br>Why Choose BOYA Metal Sheet Leveler Machine <br>The metal straightener from Boya is well designed and strong enough to be used in countless manufacturing industries.

BOYA steel cut to length machine is often used in steel rolling production line. In the continuous rolling billet workshop or small section workshop, it is placed at the end of the rolling line to cut the rolled pieces into fixed length or only the head or end of cutting part. In cold and hot rolling workshops there are various types of flying shears used in the horizontal shear unit, heavy shear unit, galvanizing unit and tin plating unit, which cut the strip into a fixed size or cut into a specified weight coil. <br> <br>BOYA cross-cutting shear is advanced, high precision, greatly promote customer production to high-speed and continuous development. <br> <br>What&#039;s Cut to Length Shear? <br> <br>Cut to length shear is a Horizontal shear machine used for unwinding, leveling, sizing, cutting into the required length of flat sheet and stacking. <br> <br>Suitable for processing cold rolled and hot rolled carbon steel, silicon steel, tinplate, stainless steel and coated metal materials. According to the application, BOYA equipment can be classified as silicon steel transverse shear line (transformer core transverse shear line), stainless steel transverse shear line, copper foil aluminum foil transverse shear line, cardboard transverse shear line and so on. According to its electronic control type can be classfied into CNC transverse shear line, pneumatic transverse shear line and so on. <br> <br>Types of metal cut to length machine <br> <br>Drum Fly Shear for Cold Rolling Mill <br>Drum flying shears are used at the exit of various continuous cold rolling mills for strips to realize dynamic sub-coiling. During the shearing process, the upper and lower drums of the flying shears make circular motions, and the shear blades installed in the drums perform shearing motion with the rotation of the drums to cut the strip. The flying shear can automatically or manually adjust the side clearance of the cutting blade through the adjustment device to meet the cutting needs of different specifications of strip steel. <br> <br>Hydraulic Shear <br>The hydraulic shear produced by BOYA Company is widely used in steel, stainless steel, and aluminum plate production lines to cut the head and tail, which is convenient for belt threading, and reduces the damage to the equipment and rollers caused by the head and tail. The sample tape can be cut and tested, at the same time. <br> <br>Cut to length machine for sale during High Speed Cut Blade Temperature Impact <br>Based on the pursuit of coil automatic cut to length machines efficiency, we need to increase the shear speed and reduce cutting time. However, while increasing the shear speed, the working temperature of the ctl machine blade rises, the force is large, causing the blade to accelerate wear. On the other hand, the blade is affected by the heat expansion, and further affects shear quality. <br> <br>In the initial stage of the shear, the overall temperature of the cut to length machine is raised. As coil metal processing machinery shear is stable, the blade is in contact with the strip, the high-temperature area is increased, and the remainder temperature is slightly reduced; after shear enters the steady-state, the blade edge temperature Although it increases, the increase is gradually reduced until it is stable in a constant temperature. <br> <br>For more information about cut to length machine price and cut to length machine videos, please feel free to contact us! <br> <br>There are many cut to length machine manufacturers, but we are one of the best choices for you. <br> <br>Boya company, as an excellent flat rolling manufacturer, offers a wide range of steel plant finishing line for you to choose from. <br>#metal#cut#to#length#machine <br>[a]https%3A%2F%2Fwww.boyamachinery.com%2Fproducts%2Fcut-to-length-machine%2F%0A%0A%0A%0A%0A%0A%0A%0A[/a]
