摘要: 以钢厂100 t钢包为原型,根据相似原理建立1:4水模型,研究了双孔底吹位置(0.54~0.72R)、角度(45°~180°)和底吹流量(0.04~0.55 m~3/h)对混匀时间和钢-渣界面的影响,以确定最佳底吹工艺参数。结果表明,透气砖布置的最优位置为底吹孔距钢包底面中心0.63R,180°夹角;最大底吹气量在0.37 m3/h(原型18.0m3/h),软吹气量必须小于0.12 m3/h(原型小于6.0 m3/h),建议软吹气量≤0.04 m3/h(原型≤2.0 m3/h)。

Abstract: According to the prototype 100 t ladle in steel works and based on similarity theory, a 1:4 water model is established to study the effect of double nozzle bottom blowing position (0. 54 ~0. 72 R), angle (45° ~ 180°) and bottom blowing rate (0. 04 〜0.55 m3/h) on mixing time and steel-slag interface and get optimum bottom blowing parameters. Results show that the optimum position of gas permeable brick is bottom nozzle distance from ladle bottom center 0. 63 R with angle 180° ; the maximum bottom blowing gas rate is 0. 37 m3/h (corresponding prototype 18. 0 m3/h), the soft blowing rate should be less than 0. 12 m3/h (prototype less than 6. 0 m3/h) and the suggested soft blowing gas rate is no more than 0. 04 m3/h (prototype no more than 2. 0 m3/h).
