摘要
介绍了厚大断面球铁托轮的铸造工艺及其生产实践。采用数值模拟预测铸造缺陷,依据模拟结果调整冒口、冷铁布局;采用优质生铁、纯净的废钢及合理的球化温度和浇注温度,获得了无缺陷、组织良好、力学性能优异的托轮铸件。
This article introduces the casting process and production practice of heavy section ductile iron roller.In the process of casting process design,numerical simulation software ProCAST was used to predict the casting defects,and based on the simulation results,the layout of risers and chills was adjusted.By using high quality pig iron and pure scrap steel,and adopting reasonable spheroidizing temperature and pouring temperature,high quality roller castings with sound microstructure and excellent mechanical properties have been obtained.
