一、前言目前H型钢主要是在万能一轧边可逆式连轧机组上轧制的。在万能孔型中轧制H型钢时,由于存在轧件边部与腰部咬入的不同时性、边部和腰部在变形过程中的互相牵拉作用及金属流动,腰部一般出现全后滑,边部变形区为异径、异步、单辊传动的综合轧制过程,以及连轧中机架间出现张力等特 First, the preface At present, H-beam is mainly rolling in a universal one rolling edge reversing continuous rolling mill. In the universal hole rolling H-beam, due to the existence of the rolling edge and waist bite at the same time, the edge and the waist in the deformation process of mutual pull and metal flow, the waist generally appear all-slip, The deformation area of ​​the side is the comprehensive rolling process of different diameter, asynchronous, single roller drive, and the special tension occurs between the racks in the continuous rolling
