摘　　要：对12%Cr超超临界转子重熔过程进行计算机模拟及小锭型中试,模拟结果表明选取的工艺参数合理。通过严格控制原始电极质量,采用CaF2-Al2O3-CaO-MgO-SiO2五元渣系、惰性气体保护、铝和硅钙间隔脱氧的重熔工艺参数能满足产品技术要求。The computer simulation and the pilot test of small ingots are conducted for the remehing process of 12% Cr uhra-supercritical rotor. The simulation results indicate that the selected process parameters are proper. The technical requirements of products can be met by strictly controlling the quality of original electrode, and adopting the remelting process parameters of a five-element slag system of CaF2-Al2O3-CaO-MgO-SiO2, inert gas shielding, aluminum and calcium-silicon interval deoxidizing.
