对两台连铸设备中的浸入式水口进行水口沉积物特征的描述,分析和讨论了来自脱硫钢和非脱硫钢两种钢的不同的沉积物,大多数情况下,这种沉积物与钢中非金属夹杂物的组成密切相连。在脱硫钢和非脱硫钢中观察到了不同的沉积物。研制了一种在给定温度下估算固体夹杂物比例的方法,当固体夹杂物的数量超过了临界值,就会发生水口堵塞。分析了处理情况,并说明了固态部分中氧化物夹杂物的比例。
Describing the characteristics of nozzle deposits for submerged entry nozzles in two continuous casting facilities, analyzing and discussing different deposits from both desulfurized and non-desulfurized steels, most often associated with steel The composition of the metal inclusions in Central Africa are closely linked. Different deposits were observed in desulfurized and non-desulfurized steels. A method of estimating the proportion of solid inclusions at a given temperature was developed. When the number of solid inclusions exceeds the critical value, nozzle clogging occurs. The treatment was analyzed, and the ratio of oxide inclusions in the solid part was described.
