Geometrical Analysis on End-Face Grinding for Hot Roller with Cup-Shaped Wheel
The technology of On-line hot roll grinding (ORG, for short) is one of new technologies of hot strip mill appearing in recent years. It is distinctly for on-line roll grinding technology to increase quality of production and efficiency of producing, and save energy. Therefore, studying and applying ORG technologies is paid more attention to by iron and steel corporations. Many ORG technologies adopt the type of end-face grinding to rehabilitate hot rolls online. However, few studies have been done on the grinding mechanism for this grinding mode. In this paper, some grinding mechanisms of end-face cylindrical grinding with cup-shaped CBN resin wheel are studied from the point of grinding geometry. The equation is deduced to calculate the contact length. The characters of contact length are studied.
