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 A12O3 ,5Na2O/ MgO,5SiO2 ). 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 line has no obvious corrosion.
