The operating process, microstructures, mechanical properties and cost of the low alloy martensitic nodular cast iron grinding balls using EPC and immediate quenching were introduced in this paper.
介绍了采用真空消失模铸造(EPC)低合金余热淬火马氏体球墨铸铁磨球的工艺、磨球的组织、力学性能、生产成本以及使用性能,并与采用金属型铸造的相同材质的磨球进行了对比。
By adopting immediate quenching, the production cost will be reduced greatly.
若采用余热淬火可大大降低磨球的成本。
The main reasons of the brit-de fracture are the lack of the harden heat, the time of the heating preservation is too long, which make steel produce graphitizing , and the castingbranch - like crystals and wei - tissues still exist.
