摘要
针对唐钢不锈钢3#连铸机塞棒和中间包上水口吹氩工艺进行了原型与模型比例为2∶1的水模实验,研究了同一种板坯宽度、同一种水口条件,不同拉速、不同水口浸入深度下,塞棒和中间包上水口的临界吹气量,以及吹气量对于结晶器流场中液面波动和流股在窄边冲击点的影响规律,为现场生产中结晶器吹氩工艺参数的优化提供依据。
A 2∶1 water model experiment was carried out aimed at the argon blowing of stopper and tundish upper nozzle of 3# slab caster in stainless steel company of Tang Steel. The critical argon gas flow rate of stopper and upper nozzle, and the behavior of the fluctuation on surface and the depth of impact points in the narrow side of the mold under different gas rates were studied under the same slab width and nozzle condition, and various casting speed and immersion depth. The optimized parameters of argon injection in the mold were provided to effectively improve casting production in steel plant.
