摘要
针对转炉顶吹氧枪或底吹喷枪喷出的气体,从常温状态迅速升温达到炉内高温状态时,体积急剧膨胀的实际生产情况,设计制作了非等温矫形模化实验模型,实验研究复吹转炉熔池内的流动与搅拌混匀特性,以及流体对炉壁的冲刷作用．比较了非等温矫形模化实验结果与未考虑温度影响的常规等温模型实验结果,发现非等温矫形模化所需要的底吹供气强度明显降低,约为0．04 m3／(min·t);其它条件相同的情况下,炉役前期熔体对炉壁的冲刷作用较炉役中期强,中后期的冲刷情况相差不大．
Contraposing gas that ejects from top blown oxygen gun or bottom blown ejection gun expands sharply from normal temperature to elevated temperature. Non-isothermal rectification analog experiment models are designed and made. The flowing property and mixing characteristics in the combined-blown converter and fluid erosion on wall are tested. Comparing non-isotherm rectification model with general cold model, the bottom aero supplied strength needed for mixing in the former model is apparently lower, approximately 0.04 m^3/（ min·t）. When other conditions are the same, the force of smelting body eroding the inside wall of the converter service in the early stage is stronger than that in the middle stage. The erosion actions in middle and evening stage are equivalent.
