摘　　要：为解决铸铁熔炼所需原材料生铁价格的不断上涨,以及生铁的长期使用带来的遗传影响,使铸铁产品的力学性能和金相组织出现一定恶化等问题,在缸体类铸铁产品的生产中,采用合成铸铁,即废钢加增碳剂增碳的方式进行铸铁生产。通过试制,采用合成铸铁生产的缸体类产品力学性能和金相组织均优于传统熔炼工艺生产的铸铁产品,提高了质量,降低了成本。The price of pig iron is continually rising; and the mechanical property and metallographic structure of the castings getting worse resulted from the long time using of pig iron. To resolve the problems above, the synthetic cast iron, i.e. scrap steel with carburant, was applied to thecylinder＇s production. Results of trial production show that both the mechanical property and microstructure of cylinder castings produced with the synthetic cast iron are better than that of the traditional ones, further more, this method not only improve the aualitv but also reduce the cost.
