| 摘 要： | 我公司生产的60 t蠕墨铸铁钢锭模在浇注过程中发生开裂。采用低倍检验、化学成分分析、宏观断口分析、扫描电镜分析、金相检验等方法对开裂原因进行了分析。结果表明：钢锭模开裂的主要原因是石墨漂浮、石墨形态较差以及蠕化率较低。

| Abstract: | The 60 t vermicular graphite cast iron ingot mold produced by our company has arisen cracking during the pouring process. The cracking causes are analyzed by macroscopic test,chemical components analysis,macro-fracture analysis,scanning electron microscope analysis and metallographic examination. The results show that the cracking of ingot mold is caused by graphite floating,poor graphite morphology and low creep ratio. |
