摘要
结合H钢厂的实际情况,采用有限元分析法对新钢包温度场进行研究,进而采用ANSYS数值模拟软件对钢包从烘烤至周转过程进行了数值模拟,重点分析了预热烘烤对新钢包热状态及钢水温度的影响,并进行了试验验证。结果表明:新钢包预热烘烤25 h虽然达到红包状态,且包壁温度趋于热饱和,但是包底仍有蓄热升温空间,周转后钢包造成钢水的最大温降约10℃;预热烘烤55 h后,钢包整体趋于热饱和,周转后钢包造成钢水温降不到1℃,因此可知理想的预热烘烤时间为55 h,为炼钢厂钢包烘烤制度及出钢温度制度的制定提供了参考。
In light of the practical situation of Steelmaking Plant H the temperature field of the new ladle is studied by the finite element analysis method. Then the full process from preheating to the turnover of the ladle is numerically simulated using the numerical simulation software ANSYS and the effects of ladle preheating on the thermal conditions and hot metal temperature are emphatically analyzed and verified as well. Results show that although as a whole the ladle turns to become a hot ladle and the temperature of the ladle wall tends to be in a state of heat saturation after being preheated for 25 hours, yet there is still room for the ladle bottom to store certain heat （temperature rise） and the temperature of the hot metal in the ladle probably drops by about 10℃ after the turn- over of the ladle. However after the ladle is preheated for 55 hours the ladle tends to be heat saturated and the temperature drop of the hot metal in the ladle is less than 1 ~C af- ter the turnover of the ladle. Therefore the ideal preheating time for the ladle is 55 hours and it can be used as the reference for the similar steelmaking plant in establishing a proper baking regime and steel tapping temperature schedule.
