The pre finishing mill of high-speed wire rod mill is derived from the second intermediate rolling mill. The function of pre finishing roll ring is to continue to reduce the cross-section of rolled piece produced by medium rolling mill, and provide intermediate material for finishing mill to roll finished wire rod with correct section shape, accurate size, uniform size along the whole cross-section, and no internal and surface defects, so as to improve the precision of wire rod products and reduce the cost Finish rolling process failure.
