Using the rolling line adjusting device of our company 's patent design, we can ensure that the surface of the rolling process is automatically separated, which greatly reduces the failure loss;
-- all the equipment figure CAD design, the frame uses the three-dimensional finite element method optimization design;
- supporting roller and working roll, middle roller with four short cylindrical roller bearings, roller bearings lubricated by oil and gas lubrication, and can effectively extend the bearing life, reduce production costs.
