摘要: 通过几何相似比1:3.4的水模型对41~45 t原有圆形钢包和新型钢包冶金特性进行了对比,并得出最佳吹Ar的位置。结果表明,原有圆形钢包高径比比较大、混匀时间较长并且工艺稳定性不高;新型钢包降低了高径比,混匀时间显著缩短。同时发现新钢包底部使用单透气砖吹气比双透气砖吹气效果更好。生产实践表明,新型钢包加碳粉后混匀时间从原来的8~10 min减少到4 min,水口自动开浇率由80%提高至95%以上,钢材中大颗粒夹杂出现率由原来的3%降至1.5%以下。

Abstract: Comparison between the metallurgical characteristics of 41 ~45 t original circular ladle and new-type ladle has been carried out by using geometric similarity ratio 1:3.4 water model and the optimum location of argon blowing is obtained. Results show that for original ladle the height-diameter ratio is rather large, the mixing time is longer and the process isn't stable ; and for new ladle the height-diameter ratio decreases and the mixing time reduces obviously. While it is found that the blowing effect of single porous brick is better that of double porous bricks at new-type ladle bottom. Production practice indicates that with using new-type ladle the mixing time after adding carbon powder decreases from original 8 ~ 10 min to 4 min, the nozzle auto-open pouring ratio increases from 80% to more than 95%, and the large inclusion occurrence ratio in steel products decreases from original 3% to 1. 5%.
