摘要
采用电弧炉冶炼+LF精炼+VD真空除气+电渣重熔工艺生产7吨级40CrNiMoA钢锭,并锻造了曲轴毛坯。提出了电极坯及电渣锭制备工艺制度,确定了锻造及锻后热处理工艺。各项技术指标均达到了质量要求。
The 7 tons grade of 40CrNiMoA steel ingot has been produced by electric arc furnace smelting+LF refining+VD vacuum degassing+electroslag remelting,and the crankshaft blank has been forged.The preparation process of electrode blank and electroslag ingot has been put forward,and the forging and heat treatment processes have been also determined.All the technical indicators meet the quality requirements.
