摘要
以宝钢一连铸板坯结晶器为研究对象,采用多相流模型计算了吹氩后结晶器内钢液的流场、温度场及氩气分布.结果表明:吹氩后,结晶器内上回流区钢液的流动强度增大,下回流区变小;钢液的温度梯度减小,温度分布均匀;氩气的分布不均匀,上回流区钢液的含气率大大高于下回流区.
Taking the mold of No.1 continuous slab-casting machine in Baosteel as the object, a multi-phase model was applied to simulate the velocity, temperature fields and gas distribution of molten steel with argon injection. The results indicate that the velocity of upward flow increases, the lower re-circulation region appears small, and the temperature gradient decreases. Argon bubbles distribute unevenly and the gas holdup of liquid steel in the upper region is far higher than that of the lower region.
