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。
The Exploitation and Application of Acicular Structure Nodular Cast Iron Roller 针状球铁轧辊的开发和应用
The microstructure of 84% acicular ferrite and 16% retained austenite in the low carbon modular cast iron was obtained by austenitizing at 900 ℃ and austempering at 370 ℃ for proper time then air cooling to room temperature. 低碳球墨铸铁经过900℃奥氏体化,在370℃等温适当时间,空冷到室温后可以获得约84%簇条状铁素体和约16%的残留奥氏体组织。
