摘要

以抚钢二炼钢厂30 t VOD精炼不锈钢的生产数据为依据

分析了入VOD精炼钢水C(0.50%～0.93%)、Si(0.18%～0.42%)含量对喷溅以及吹氧过程温度的影响

证明C、Si含量高(C≥0.65%

Si≥0.22%)是导致吹氧前喷溅事故的主要因素

而C、Si含量低所引起的温升不足又影响后续冶炼的质量和效率。冶炼实践表明

为避免喷溅事故

当钢水[C]≥0.90%或[Si]≥0.40%时不得进行VOD精炼。在VOD吹氧冶炼前钢水中C、Si含量分别为0.40%～0.65%和0.12%～0.20%

能够满足VOD精炼不锈钢的要求。

Abstract

Based on production data of 30 t VOD process refining stainless steels at Second Steelmaking Plant

FuSteel

the effect of C (0. 50% ~0. 93% ) and Si (0. 18% ~0. 42% ) content in liquid for VOD refining on splashing and temperature of steel in oxygen blowing process has been analyzed. Results prove that the high C and Si content (65% C

≥ 0. 22% Si) are main factors led to splashing accident in initial period of oxygen blowing

while the low C and Si content in liquid lead to insufficiency of increased temperature of liquid and influence on quality of liquid and efficiency of later refining. The steelmaking practice shows that in order to avoid splashing accident the liquid with [C] ≥0. 90% and [ Si] ≥0. 40% is not available to refine by VOD process

and before VOD oxygen blowing the C and Si content in liquid are respectively within 0. 40% ~ 0. 65% and 0. 12% ~ 0. 20%

it is able to meet the requirement of VOD refining stainless steels.
