摘要: 应用相似原理和流体力学理论,利用电导率法和PHOENICS平台对钢包精炼炉(上、下口直径分别为2 310 mm和1 984 mm,内腔高2 620 mm,透气砖直径104 mm)钢液流动状态进行了水模拟和数学模拟,由实验和计算结果得出,离钢包底中心520 mm的2#底吹位置比离中心354 mm的1#位置获得的流场和均匀时间更合理,在≤300 L/min时,随吹气量增大,混匀时间减少,但>300 L/min时,继续增大吹气量,混匀时间不再变化。40 t BOF-LF-CC生产结果表明,采用优化工艺后,钢中全氧量降低2×10-6,达到15.2×10-6,钢中夹杂物也显著减少。

Abstract:  Using similitude principle and hydrokinetics theory, the water simulation and mathematic simulation of molten steel flow condition in ladle furnace (upper and bottom diameter- 2 310 mm and 1 984 mm, height of ladle furnace- 2 620 mm, porous block diameter- 104 mm) have been carried out by conductivity testing and Phoenics software. The test and results showed that the molten steel flow pattern and mixing time at 2 # blowing location (520 mm from ladle bottom center) was more idea than that at 1 # blowing location (354 mm from ladle bottom center) ; and as argon flow rate no more than 300 L/min, with increasing blowing rate the mixing time decreased, as aigon flow rate more than 300 L/min, with further increasing blowing rate the mixing time no longer change. The results of 40 t BOF-LF-CC production showed that with using optimum process the total oxygen content in steel decreased by 2x 10-6 , to 15.2 X 10-6 , and the amount of inclusion in steel decreased obviously.
