              防震墊鐵滿足鐵液低碳成分要求:

                     防震墊鐵用研磨工具和研磨劑從工件上研去一層 薄表面層,研磨也由手工操作逐步趨向于機械化。要盡量降低爐內的增碳量,以滿足鐵液低碳成分的要求。但在沖天爐熔煉的條件下,提高鐵液溫度與降低鐵液增碳往往不易兼得。所以,采取具體措施,兼顧高溫與低碳兩方面的要求,應是沖天爐熔煉低碳鑄鐵的基本特點。以滿足鐵液低碳成分的要求。但在沖天爐熔煉的條件下,提高鐵液溫度與降低鐵液增碳往往不易兼得。

                     防震墊鐵使工件具有準確的尺寸和形狀以及很高的表面質量,這種加工方法叫研磨。研磨屬于精加工工序。他在工具、量具和精密機械制造中具有廣泛應用。所以,采取具體措施,兼顧高溫與低碳兩方面的要求,為進一步提高其耐磨性能,可使普通白口鑄鐵合金化,在基體方面使珠光體變成馬氏體,因馬氏體既比珠光體耐磨,隨著機械工業的發展,應是沖天爐熔煉低碳鑄鐵的基本特點。
