Factors Affecting Dimensional Tolerance of Section Steel

1.The stability of the rolling mill, that is, the vibration frequency of the rolling mill, mainly refers to the overall stability of the equipment, including the firmness of the equipment foundation frame, the structural material of the rolling mill door frame and other factors.

2.The smaller the clearance of rolling mill bearing, the smaller the tolerance of the product produced. In order to reduce the tolerance, many industries require the rolling mill to replace the bearing with copper sleeve.

3.The flatness of the roll surface. The roll will inevitably wear during use, resulting in concave grooves. When the wire is not in a plane, the product tolerance will also be large.

4.The running speed of the rolling mill. The speed of the rolling mill will directly affect the density of the product rolled by the roll. The size will change when the constant density of the cross section changes.
