摘要

研究了不同低频电渣重熔对NO8367奥氏体不锈钢电渣锭质量的影响。结果表明

在经过重熔之后的铸锭各方面性能都得到了显著提升

尤其是在7.5Hz频率下制备的试样

其夹杂物数量最少

力学性能最佳

断裂方式为呈韧窝断裂形式

表现出良好的塑性。

Abstract

The effects of electroslag remelting with different low frequencies on the quality of NO8367 austenitic stainless steel ingots were investigated.The results show that the properties of the ingots after remelting are significantly improved

especially in the samples prepared at 7.5 Hz

where the number of inclusions is the least

and the mechanical properties are desirable with tough fracture morphology.
