摘要

采用两组不同渣系对耐蚀模具钢FS136进行电渣重熔对比试验，取样分析化学成分和非金属夹杂物来研究电渣重熔渣系对耐蚀模具钢FS136中夹杂物的影响。在试验条件相同的情况下，进行试验的二元渣系（CaF

-Al

）与四元渣系（CaF

-Al

-CaO-MgO）对于FS136模具钢中元素烧损无明显差异。经金相分析和扫描电镜分析结果表明，FS136钢中非金属夹杂物以D类夹杂物为主，其构成为Al

类型的颗粒状夹杂物。采用四元试验渣系的FS136钢中该D类非金属夹杂物的控制达到0.5~1.0级，与二元试验渣系相比，四元试验渣系有助于提高熔渣对该D类非金属夹杂物的润湿、吸收与去除效果，可进一步提升耐蚀模具钢FS136的纯净度。

Abstract

Through the analysis of the chemical composition and non-metallic inclusions data of sampling experiments using two groups of different remelting slag systems to investigate the effect of electroslag remelting slag systems on non-metallic inclusion in corrosion-resistant die steel FS136， under identical experimental conditions， experiments with the binary（CaF

-Al

） and the quaternary（CaF

-Al

-CaO-MgO） slag systems showed no significant difference in alloying element loss. Metallographic observation and SEM analysis show that the non-metallic inclusions in FS136 steel are mainly Type D inclusions consist of Al

-based

granular inclusions. In FS136 steel processed with the quaternary experimental slag system， the Type D non-metallic inclusions were controlled to a rating level of 0.5–1.0. Compared with the binary slag system， the quaternary slag system exhibited better performance in wetting， absorption， and removal. The quaternary slag system can further improve the cleanliness of corrosion-resisant die steel FS136.
