The rolling process of the rolling mill is divided into two steps: hot rolling and cold rolling. 1. Hot rolling process: the billets from the steel plant are only semi-finished products, which can only be qualified after being rolled in the rolling mill. The continuous casting billets sent […]

In the process of rolling profiles in the rolling mill, there are usually two processes, roughing rolling and finishing rolling. One is continuous rolling, the other is a combined rolling method with another non-continuous rolling, which is often used in alloy steel rolling or the transformation of old equipment.

Work Roll Material Selection The work rolls of rolling mill roll before rough rolling (R1): Work rolls before rough rolling must have toughness, wear resistance and thermal crack resistance. The hardness range is about HS40-55. Generally, 60CrNiMo cast steel and other material rolls are used. Work rolls after rough rolling

1. The Production Accident of Jamming The production accident of jamming refers to a fault phenomenon in which the rolling stock is stuck on the rolling line due to the influence of the surrounding environment during normal operation, and cannot be rolled in the downstream direction. The main reasons for
