中硅耐热球墨铸铁在铸铝坩埚上的应用

The Applicaticn of Medium Silicon Heat-Resisting Nodular Cast Iron to Make Cast Aluminium Crucible

依据铸铝坩埚的服役条件,制造工艺和成本要求,选择中硅耐热球铁取代普通灰口铸铁制造铸铝坩埚.通过对其制造工艺、力学性能、抗氧化性、抗生长性以及金相组织分析和现场生产试验,考察了用中硅耐热铸铁制造铸铝坩埚的可行性.

Medium silicon heat-resisting nodular cast iron has been chosen instead of common grey iron to make cast aluminium crucible according to the work condition.making process and cost of the crucible.The feasibility of making cast aluminium crucible of medium silicon heat-resisting nodular cast iron has been examined by analyzing the making process.mechanical properties.antioxidizability,growing-resistance and metallographic microstructure.and testing in production site.
