Leon mill Roll China co.ltd. By default, the strip width in a hot-strip mill is deter-mined by edging and rolling the strip in the roughing mill. The width deviation after the finishing mill arises from the width deviation in front of the finishing mill and from width-spread anomaly occurring inside the finish-ing mill. The behavior of width spread in a finishing mill depends on effects in roll bite and on the creep defor, Rolling Mill Guide Equipments . In hot rolling mills for long products, guide equipments guide the rolling stock at the entry and the exit of the roll pass so as to have smooth rolling of the rolling stock.

Heating of Cold Stock One of the prequisites of the hot rolling practice is heating the input bloom/billet/slab from the room temperature to the rollable temperature. At that higher temperature the steel is transformed in to a Secondary scale on hot strip and the impact on wear is another issue.
