研究了单电源双回路载流结晶器电渣重熔工艺。本文通过实验室试验、物理模拟和数值模拟等方法，系统研究了电渣重熔拉坯工艺（ESRW）和ESR-STCCM工艺下重熔锭液滴尺寸和洁净度的变化规律。结果表明，在相同重熔功率的情况下，电渣重熔连铸可以改变电磁力的分布，从而减小熔滴尺寸。利用ASPEX explorer软件对不同重熔工艺下铸锭中的非金属夹杂物进行了研究，结果表明：不同重熔工艺下铸锭中非金属夹杂物的种类没有发生变化，但ESR-STCCM下非金属夹杂物的数量减少了42.3%。与ESRW相比，ESR-STCCM的脱氧能力提高了10.7%，脱硫能力提高了24.5%。
Single power two circuits electroslag remelting process with current carrying mould (ESR-STCCM) has been developed to remelt high alloy. In the present work, the laboratory experiments, physical simulations and numerical simulations were set up to systematically investigate the droplet size and cleanliness of the remelted ingot for ESR withdrawing process (ESRW) and ESR-STCCM. The results indicated that ESRSTCCM can change the distribution of electromagnetic force, thereby reducing the droplet size in the case of the same remelting power. ASPEX explorer was utilized to investigate the non-metallic inclusions of the remelted ingot for different remelting processes, and the result indicated that the types of the non-metallic inclusions for the different remelting processes were not changed, however, the number decreased by 42.3% for ESR-STCCM. Compared with the ESRW, the deoxidation ability of ESR-STCCM increased by 10.7% meanwhile, the desulfurization ability increased by 24.5%.
