GH132高温合金炉底辊电渣熔铸工艺实践

摘要

The GH132 alloy rolls used for electroslag remelting furnace have been successfully fabricated by the ERC (electroslag remelting casting) and heat treatment process. The mechanical properties of the rolls obtained meet the design requirements, and the process is simple and economic as compared to the original process of casting, forging and then heat treatment.%采用电渣熔铸+热处理工艺,代替铸造+锻造+热处理工艺成功制造了连铸生产线上GH132高温合金炉底辊.采用五元渣系、4 000 A电流和57 V电压生产的炉底辊铸件,经720℃+16 h+空冷处理后,其各项力学性能指标均达到炉底辊铸件的设计要求.
