摘要
本文重点研究了双相不锈钢F55的电渣重熔工艺,研究发现,F55电极经过电渣重熔后钢中氧含量增加,经扫描电镜检测分析,钢中的夹杂物类型主要为高熔点的Al2O3。通过优化电渣工艺,采用CaF2-CaO-Al2O3-MgO-SiO2五元渣系,同时渣中加SiCa、Al对熔渣进行脱氧,Al2O3夹杂物发生变性,形成低熔点复合夹杂物,易于从钢中去除,从而实现F55电渣过程夹杂物的有效控制。
The electroslag remelting of F55 duplex stainless steel is investigated.Results show that the oxygen content increasesafter the electroslag remelting of the F55 electrode.The inclusions in the steel are mainly Al2O3 by SEM analysis.By optimizingthe ESR process,using the slag of CaF2-CaO-Al2O3-MgO-SiO2 and adding SiCa and Al to deoxidize,the Al2O3 inclusions become deformed and the melting point becomes low,so the inclusion is easy to be removed from the steel,realizing the controlthe inclusions in the process of electroslag remelting of F55.
