中大型耐磨铸钢件的消失模铸造

摘要

According to the process characteristics of lost foam casting and the alloy feature, specific structure, mechanical properties and application performance requirements of wear resistant steel castings, the common defects causes of the castings were analyzed. The method and characteristics of lost foam casting for wear resistant steel casting were introduced, and the content and main points of process design were elaborated, which can provide the references for establishing the reasonable lost foam casting process.%针对消失模铸造工艺特点和中大型耐磨铸钢件的合金特性、具体结构、力学性能和使用性能要求,分析了该类铸件常见缺陷成因.介绍了耐磨铸钢件消失模工艺设计方法和特点,阐述工艺设计内容和要点,为制定出合理的消失模铸造工艺提供借鉴.
