submerged entry nozzle clogging(In addition, the application of PTH also greatly reduced the occurrence of submerged entry nozzle clogging. 此外，使用等离子体中间包加热器还大幅度降低了浸人式水口堵塞的发生。)
clogging of submerged entry nozzle(The following topics were studied: quantification of waves and vortices; clogging of the submerged entry nozzle (SEN);； eccentricity of the SEN; and mold powder entrapment by the slag rim. 对以下课题进行了研究：波动和旋涡的量化、浸人式水口 (SEN) 堵塞、浸人式水口偏置和渣圈卷人结晶器保护渣。)
