中硅耐热铸跌是由化铁炉熔得的一种中等硅量的合金铸铁,它具有比普通铸铁更高的耐热性及抗触性,尤其在高温时,氧化性气氛对它的侵蚀不大,在升温过程中组织不发生相变,故在高温作业下工作性能很好。由于它的制造周期短、成本低、寿命长,故生产率及经济效果都很高。 The heat-resistant silicon casting is a medium-sized silicon alloy cast iron which is melted by the iron furnace, which has higher heat resistance and anti-contact ability than ordinary cast iron, especially at high temperature, the oxidizing atmosphere of it Erosion is not big, in the process of warming does not happen to the phase change, so work under high temperature performance is very good. Due to its short manufacturing cycle, low cost and long life, its productivity and economic efficiency are high.
