摘要
以攀钢165 t LF炉为原型,根据相似原理,用冷态模拟的方法对影响LF炉吹氩混合效果的各种工艺参数进行了研究.应用多因子多水平正交表安排试验,单底吹选用L18(61×36)表,双底吹选用L32(81×48)表.通过考察各因素对指标混合均匀时间τm(s)影响的显著程度,得出了165 t LF炉吹氩的最佳工艺条件为:(1)单底吹:Qm=3.37 L／min;Sm=1.7 mm3;Hm=506 mm;rm=124.8 mm;(2)双底吹:Qm=3.61 L／min;Sm=:1.7 mm2;Hm=500 mm;rm=142.4 mm或98.6 mm.
Using 165 t LF of Panzhihua Steel and Iron Co.as the prototype,the technical parameter of LF argon bubbling was studied by means of hydrodynamic modeling with similarity theory.Orthogonal tables L18(6136) and L32(8148) were used in the single bottom blowing and twin bottom blowing tests respectively. From investigation of the influences of main factors on uniforming mix-time τm (s) , the optimal technical conditions of LF argon bubbling was as follows: (1) single bottom blowing test: Qm = 3.37 L/min, Sm = 1.7 mm2, Hm = 506 mm, and rm = 124.8 mm,(2)two bottom blowing test: Qm = 3.61 L/min, Sm = 1.7 mm2, Hm = 500 mm, rm = 142.4 mm or 98.6mm.
