以210 t未加绝热层的无碳新钢包为研究对象,建立数值模拟模型进行计算,并利用实际生产数据进行验证。计算结果显示:新钢包蓄热到第10周期达到热饱和状态;新钢包阶段由于蓄热所造成的钢水最大温降为18.3℃,据此建立了新钢包阶段的钢水温度补偿模型。实际应用结果表明,该温度补偿模型的应用提高了中间包的钢水温度命中率,对炼钢厂的生产具有一定指导意义。
Taking 210 t non-carbon steel ladle without insulation layer as the research object, a numerical simulation model was established to calculate and make use of the actual production data to verify. The calculation results show that the new ladle heat storage reaches the thermal saturation state in the tenth cycle and the maximum temperature drop of the molten steel in the new ladle stage is 18.3 ℃. Based on this, the molten steel temperature compensation model for the new ladle stage is established. The practical application shows that the application of the temperature compensation model can increase the temperature hit rate of the molten steel in the tundish and has certain guiding significance for the steelmaking plant.
