摘要:: 本文叙述了铸态铁素体韧性球铁的机械性能,分析了主要工艺因素对球铁机械性能的影响。生产中选用Mn<0.4％,P<0.08％,S<0.04％的生铁;冲天炉熔炼,用FesiMgBRe7中间合金进行球化处理;采用Fesi75硅铁,多次强化孕育技术.结果,底宽25mm的基尔试块和铸件的铸态组织,石墨球化1—3级,石墨球大小5—7级,铁素体比例80％以上,机械性能达到了ISO400—18的水平.

Abstract:: This article describes the mechanical properties of the cast -to -iron body tough ball iron, and analyzes the impact of the main process factors on the mechanical properties of the ball iron. In the production, MN <0.4 %, P <0.08 %, S <0.04 % of the raw iron; the heavenly furnace melt, use Fesimgbre7 intermediate alloy for ballization; use FESI75 silicon iron to strengthen the breeding technology multiple times. As a result, the Cafe test block and casting of the bottom 25mm, granite 1-3, graphite level 1-3, graphite, graphite, graphite, graphite The size of the ball is 5-7, the ratio of ferrite is more than 80 %, and the mechanical performance reaches the level of ISO400-18.
