摘要: 炼钢厂产能提升及大废钢比生产模式转变,对钢包扩容使用提出了要求。通过模型化与数值计算对钢包扩容后温度场、应力场变化进行了分析,扩容后钢包达到稳态循环后包壁外表温度最大值280 ℃,渣线位置达到最大值310 ℃,处于安全范围。包壁工作层厚度减薄30 mm,钢包有效容量由277 t增加到286 t,月产能增加1.8万t,促进炼钢产能提升的同时,降低了动力费用、耐材费用、人工费用,实现年经济效益约1 400 万元。

Abstract: In view of steel production capacity improvement and the transformation of big scrap steel ratio production mode, the requirement for ladle volume expansion was put forward. Through modeling and numerical calculation after ladle volume expansion,the temperature field and stress field were analyzed. After the expansion ladle reached the steady-state cycle, the ladle wall surface temperature reached the maximum value of 280 ℃,and the slag line position reached the maximum value of 310 ℃, which was in the safe range. The thickness of the working layer of ladle wall was reduced by 30 mm, the effective capacity of the ladle was increased from 277 t to 286 t, and the monthly production capacity was increased by 18 000 t. While promoting the improvement of steelmaking capacity, the power cost, refractory cost and labor cost were reduced, and the annual economic benefit was about 14 million yuan.
Key words: ladle, expansion, effective volume, surface temperature, refractory
