| 摘 要： | 通过物理模拟研究了2200mm×280mm 宽厚板坯连铸结晶器吹氩时其内界面波动行为,考察了吹气量、拉速对结晶器内液面波动的影响。结果表明:结晶器吹氩后,各气量下液面平均波高均增加了1.2倍以上,且液面影响的区域集中在距水口2/3断面宽度范围内,弯月面附近的波动影响则较小。与常规板坯连铸结晶器内液面平均波高随吹气量、拉速的增加而增大的规律不同,本实验中随这两个工艺参数的增加液面平均波高均先增大后减小,并从实验条件下得出了控制液面波动的最佳气量。 |

| Abstract: | A physical model was established to study the interfacial fluctuation in a wide plate continuous casting mold with argon blowing and the effects of gas flow rate and casting speed on it were investigated.The results showed that the average surface fluctuations all increased by 1.2 times under all the gas flow rate with argon blowing than that without argon blowing and the region along the nozzle to 2/3 wide face is mainly affected,while the effect on the fluctuation of meniscus is small.Oth- er than the rul... |
