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. Selection of Bar Rolling Process Layout For hot-rolled bars, the bar rolling process layout scheme is mainly divided into continuous rolling and the semi-continuous rolling. 1.1 Semi-continuous Rolling A two-roll reversing mill + continuous rolling mill (6 or 8)are arranged generally. The two-roll mill has a front and rear turning-over

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

Advantages of Hot Rolling: Hot rolling can greatly reduce energy consumption and costs. The metal-plastic deformation is high during hot rolling, and the deformation resistance is low, which reduces the energy consumption of metal deformation. Hot rolling can improve the processing performance of metals and alloys. That is to say, the
