在生产条件下，对比了真空（负压）实型铸造（即ＥＰＣ）的有关工艺流程、工艺参数及生产技术经济指标等；同时介绍了新型针状基体抗磨铸钢材质的有关特性。生产实践结果表明，ＥＰＣ工艺生产的铸件，其主要技术经济指标远优于手工砂型工艺，明显提高了新型针状基体抗磨铸钢件的外观和内在质量，其抗磨性能较高锰钢普遍提高３倍左右 Under the conditions of production, the relevant process flow, process parameters, production technical and economic indexes of vacuum (negative pressure) real casting (EPC) were contrasted. Meanwhile, the characteristics of the new acicular matrix anti-wear cast steel were introduced. The results of production practice show that the main technical and economic indexes of the castings produced by the EPC process are far superior to the manual sand process and the appearance and intrinsic quality of the new acicular base steel with anti-wear castings are obviously improved. The manganese steel with higher antiwear performance is generally Increase about 3 times
