摘要
以我国实际生产的某连铸结晶器为原型,建立1:1有机玻璃水模型,研究了不同结晶器断面、不同中间包液位下,板坯连铸结晶器流场形态和结晶器液面波动情况,研究发现中间包液位的变化对结晶器液面流场和波动产生影响;同时中间包液位改变了水口出口的压力和流速,进一步影响结晶器流场和液面波动。实验工况条件下,最佳中间包液位的稳定高度为800 mm。建议生产过程稳定控制中间包液位,以提高连铸坯质量。
According to one kind of the molds for slab caster in china, a water model in the ratio of 1 to 1 has been established in order to study the effect of the level of steel in tundish on flow field and surface wave of mold. The results show that the flow field and surface wave of molten steel in the mold was changed with the unsteady the level of steel in tundish, at same time, Increases of the surface wave of mold owed to the change of the stress and velocity of steel flow on SEN outlet though changed the level of steel in tundish. The best level of steel in tundish is 800 mm. It is proposed that we keep the steady level of steel in tundish in order to produce the higher quality steel.
