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。

Abstract

A new electroslag furnace with mould rotation was designed

and effects of mould rotation velocity on the compact density of electroslag ingot were analyzed.Experiment results show that ESR ingot can become more compact from 77%to 94% and more uniform distribution with the mould of rotation velocity from 0to 28r/min.However

with rotation velocity to 35r/min

the compact density is deteriorated to 91%

which reveals that the solidification structure can be improved through appropriate mould motion.
