Pearlitic steels present very interesting mechanical properties when weldability requirements are not too severe. Thin gauge pearlitic steels require at least one intermediate annealing treatment between hot rolling and cold rolling. The globularised cementite in medium carbon steels provides then higher ductility, formability and machinability. On the other hand, in-line induction heating devi...

Rolling processes for which the characteristic length scale reaches into the range where size effects become important are receiving increased interest. In particularly, this is owed to the roll-molding process under development for high-throughput of micronscale surface features. The study presented revolves around the rolling induced effect of visco-plasticity (ranging hot and cold rolling) i...

In this case study we discuss a simple control system used for obtaining a desirable downstream surface temperature inside a hot rolling steel sheet, presented by Bao Steel in the HK Study Group with Industry, held at the City University of Hong Kong, July 2002.

The conditions for choosing a billet mass the manufacture of an ring part on automated ring-rolling complex, features heating billets in line and heat treatment manufactured parts are considered. expediency differentiated assignment tolerances rings’ sizes after rolling, depending their type, subsequent mechanical operation, is substantiated. Attention focused need to design technology with con...
