摘要

对攀钢集团西昌钢钒有限公司（以下简称西昌钢钒）铝脱氧钢精炼造渣机理进行了研究

根据理论分析精炼过程要求的"高碱度、高CaO活度、高熔化速度、低熔化温度"提出了一种新的无氟精炼化渣剂

主要成分为（/%:17 CaO

45 Al2O3

5 Na2O

4 MgO

5 SiO2）。该化渣剂已在西昌钢钒应用

在LF工序加入量控制在0.5～1.0 kg/t钢

新的无氟精炼化渣剂埋弧效果好

化渣速度快

M3A35等钢种3min左右即成渣

对于钢包罐侵蚀明显比使用萤石化渣好

渣线部位耐材无明显侵蚀。

Abstract

The reaction mechanism of refining slagging of aluminum deoxidized steel at Pangang Group Xichang Steel and Vanadium Co Ltd has been studied. According the theoretical analysis

the refining slag must be high alkalinity

high CaO activity

high melting rate and low melting temperature

therefore a new fluorine-free refining slag agent is proposed

its main ingredient is (/% ：17 CaO

45 A1

5Na

O/ MgO

5SiO

). The slagging agent has been applied at Xichang steel vanadium Co Ltd

the amount added in the LF process is controlled at about 0. 5 ~ 1.0 kg/t steel and good results have been achieved. The effect of submerged arc of new fluorin-free refining slag agent is good

the slag melting speed is fast

the time of slag formation about M3A35 some steel grades is only 3min

the ladle etching is obviously better than that using fluorite slag and the refractory material at the slag li

ne has no obvious corrosion.
