The Study Of Ladle Temperature Control In BOF Steelmaking Process

The modern steelworks core task is smooth pouring out the composition, size,surface quality of continuous casting billet, the continuous casting process of molten steelcasting temperature has strict requirements, so the BOF steelmaking process temperaturecontrolresearch has played a more and more important role.Molten steel temperature stable to ensure the continuous casting production process,reduce the direct raw material and energy consumption, improving the quality of castingbillet has great influence. When molten steel superheat control, stability, will push slabequiaxed crystal zone growth, the structure of the slab structure is more compact, thuseffectively reducing the casting billet central porosity and segregation, improves thequality of billet and improving the continuous casting production.The whole process of the current converter steelmaking process of molten steel fromtapping to molten steel pouring is finished is in ladle, so according to the ladle status,ladle vacant time, ladle turnaround cycle to adjusting the molten steel temperature tosuccessfully finish casting plays an important role.Based on the steelmaking plant of large number of field data, in accordance with theladle, ladle vacant time, ladle turnaround cycle conditions on ladle classification, analysisunder different conditions of ladle molten steeltemperature changes.The experimental results show that the improved ladle tapping rate, reduce red ladlevacant time and speed up ladle turnaround can effectively reduce the number of ladleturnaround and reducing ladle temperature drop, according to the field data to buildreasonable, feasible temperature compensation system for steelmaking plant, productionto provide reasonable, the optimal temperature control guidance.
