以钢厂生产用100 t钢包为研究对象,对静置过程的耦合场进行数值模拟研究,运用Fluent软件对钢包静置过程的温度场进行数值模拟计算,得到钢包加盖前后的温降变化曲线,分析包盖对钢包温度场的影响;设置钢包静置时间分别为10 min和60 min,分析静置过程包衬温度变化曲线。结果表明:钢包在前10 min温降比较快,而随着静置时间的延长,钢包温度下降的趋势变缓。钢包全程加盖技术节能效果显著,转炉出钢温度损失平均减少15℃,每吨钢成本降低0.8元以上。
Taking the 100 t ladle produced by the steel mill as the research object, the coupling field of the static process was numerically simulated and the temperature field of the ladle during standing was numerically simulated using Fluent software. The temperature drop curve before and after ladle capping The influence of the lid on the temperature field of the ladle was analyzed. The ladle standing time was set at 10 min and 60 min, respectively. The results showed that the temperature drop of ladle was faster in the first 10 min, and the ladle temperature decreased slowly with the increase of standing time. Ladle full stamping technology significant energy-saving effect, the average loss of converter tapping temperature decreased by 15 ℃, the cost per ton of steel to reduce 0.8 yuan or more.
