An Improvement in Operation for Steel Rolling Mill …

A Crop Cobble Shear (CCS) is a system for cutting steel bar and is used in a steel rolling mill (Figure 1). In normal operation, the CCS performs a single cut to chop each end of the bar. One of the alternative but significant functions of the CCS occurs when cobble is required. In this mode, the shear will chop the bar into small lengths.
