摘要
Slag entrainment in a continuous casting mold is one of the major causes of macro nonmetallic inclusions in continuous casting steel products. Stabilizing the level fluctuation is an important factor to improve steel quality. A new type of submerged entry nozzle (SEN) named self-braking SEN was designed. In the current study, water modeling experiments were performed to study the effect of self-braking SEN on level fluctuation in a continuous casting slab mold. The level position and the root mean square value of level fluctuation were analyzed through the online detection data. The results showed that the flow in the mold was more symmetrical and the tracer dispersion was more uniform. Moreover, the meniscus was also more uniform than the conventional nozzle with the self-braking SEN, especially at high casting speed.
