摘要

通过对中天钢铁公司电炉厂20钢管现行精炼渣系（/%:4～17Si0

17～34Al

40～65CaO)的动力学以及热力学分析

在确保炉渣粘度1.5～2.0 Pa·s的前提下

设计出较高吸附夹杂物能力的LF精炼渣系:（/%:6～15SiO

24～34Al

58～65CaO）。试验结果表明

该渣系能够很好地满足20钢管的质量要求

达到了去除钢中夹杂物的目的

其B类夹杂评级均≤1.0。

Abstract

Based on dynamics and thermodynamics analysis on the current refining slag system (/% ：4 ~ 17SiO

17 ~ 34A1

40 〜65CaO) of the 20 steel-tube produced at Electric Furnace Plant

Zenith Steel Group Co

the refining slag system (/% ：6 ~ 15SiO2

24 ~ 34A1

58 ~ 65CaO) for LF is designed

to ensure the appropriate slag viscosity 1. 5 ~ 2. 0 Pa

s and higher ability to sorb inclusions. The experimental results show that the slag system can well meet the quality requirements of 20 steel tube and can achieve the purpose to remove inclusions in steel with B type inclusion rating ≤1.0.
