摘要

钢的电渣重熔过程主要发生在电极熔化末端熔滴形成阶段

通过渣对钢中夹杂物吸附和溶解的渣洗作用达到提纯和净化钢液的目的

而渣-钢-夹杂物的界面张力密切影响这一过程。本文根据国内外关于电渣重熔过程常用含氟渣系界面性质的研究成果

分析了渣中CaF

、CaO、Al

、MgO、Na

O、SiO

等组元及温度对熔渣表面张力的影响规律及内在机理

同时总结了渣-钢界面张力随渣、钢成分及熔体温度、熔渣碱度的变化规律。建立电渣重熔用含氟渣系界面性质参数的经验公式和计算模型是该领域的研究方向。

Abstract

The electroslag remelting (ESR) process of steel mainly occurs in formation period of electrode-end melting drop

and the molten steel is pured and cleaned by slag washing effect as the inclusions in steel are absorbed and solved by slag

while the interfacial tension of slag-steel-inclusion closely affects this process. Based on the research achievements about interfacial properties of fluoride-containing slag system in ESR metallurgy process at home and abroad

the rule of influence of slag ingredient including CaF

CaO

MgO

O and SiO

and temperature on molten slag-steel interfacial tension and its internal mechanism are analyzed

while variation rule of the slag-steel interfacial tension with slag ingredient and steel chemical composition

liquid temperature and slag basicity are summarized. To estab

lish experience formula and calculation model of fluoride-containing slag system interfacial property parameters for ESR process is research direction o£ this field.
