A Study on Composition and structure of As-Cast Austenite-Bainite Nodular Iron Roll Collar 奥-贝球铁辊环成分与组织的研究
This paper introduced that horizontal centrifugal casting technology is used to develop the composite acicular spheroidal graphite cast iron collar for tension reducing mill of Baogang pipe mill. 介绍了采用卧式离心铸造技术,试制宝钢钢管轧机使用的复合针状球铁张减机辊环的过程。
When used in the pre-precision rolling machine group of high speed lines rolling mill, its service life has been 6~ 10 times longer than that of alloy cast iron roll collar. 用于高速线材轧机预精轧段,使用寿命比合金铸铁辊环提高6~10倍。
