摘　　要：熔炼合成铸铁,由于废钢加入量大,增碳技术成为其生产的关键技术。对合成铸铁的增碳原理、铸铁熔炼工艺进行了分析。结果表明,采用晶体石墨增碳剂,电炉熔炼合成铸铁的增碳速度明显高于非石墨增碳剂;且晶体石墨增碳剂可作为石墨的外来晶核,促进细片状A型石墨的形成,铁液白口倾向小,力学性能提高。Because synthesizes cast irons using large quantity of steel scraps, the carburetion technology becomes the key technology in its production. This article emphatically discusses the smelting technology of synthesis cast iron, from the carburetion principle and the ingredient. And mechanical property and the microstructure of synthesized cast iron are also introduced.
