Applications
Our four roller cold rolling mill is suitable for intermediate rolling and precision rolling of plain carbon steel, alloy steel, copper-aluminum and stainless steel strips. The thickness of our finished products from the precision rolling process is equal or greater than 0.10mm. The rack, screwdown gear and roll system are all significantly improved based on the original prototype, which contributes to a large rolling force, high precision and great stability and makes the mill suitable for finish rolling of high quality steel and stainless steel.
Components
Our four roller cold rolling mill can be driven by working roll or supporting roll. It includes the main motor, reducer, herringbone gear stand, universal spindle and rack. In addition, a one-piece pedestal is used, which facilities installation and debugging.

Applications
Our six roller rolling mill is suitable for rolling of wide strips, finishing strips and thin strips. It is widely used to roll plain steel and stainless steel. Equipped with a drawing device on the intermediate roll, the mill eliminates the need for arc grinding, thus effectively and precisely controlling the shape of steel plate. The bending roller used features a high rolling capacity and it is able to greatly reduce cracking on the edges of the rolls.
Components
Our six roller cold rolling mill includes the uncoiler, five roller leveler, main motor, hydraulic winding machine, desktop trolley, belt press and electric control system.
