Contact mechanics in hot strip rolling

点击翻译按钮获取中文摘要

The mechanics of roll bite contact in hot strip rolling in the interface is not well understood due to the high temperature of the strip, scale oxide on the surfaces, contact asperities and lubrication mechanism of emulsion entrained in the roll bite. It is not known how the strip surface roughness is generated after rolling. This proposed project will develop a model to simulate the contact of the roll bite and to determine the quality of the surface roughness transfer from the roll surface to the strip surface. The outcome would be significant cost savings in reduced rolling force, increased roll life, minimal surface defects and increased productivity.
