摘　　要：设计了结晶器可旋转的电渣炉,研究了旋转速率对电渣锭致密度的影响。结果表明,当结晶器的旋转速率从0增加到28r/min时,电渣锭的致密度显著提高,从77%提高到94%,且组织分布更加均匀;而当旋转速率达到35r/min时,致密度反而降至91%,这说明结晶器适当的运动可以改善钢锭的凝固组织。A -new electroslag furnace with mould rotation was designed, and effects of mould rotation ve- locity on the compact density of electroslag ingot were analyzed. Experiment results show that ESR in- got can become more compact from ？7% to 94% and more uniform distribution with the mould of rota- tion velocity from 0 to 28 r/min. However, with rotation velocity to 35 r/rain, the compact density is deteriorated to 91%, which reveals that the solidification structure can be improved through appropriate mould motion.
