Study on clogging mechanism of submerged entry nozzle of steel 38CrMoAl

By phase analysis of the clog of nozzle and type analysis of inclusion in 38CrMoAl steel, the effects of calcium treatment on nozzle scabbiness were analyzed and the mechanisms of clogging were discussed. The results indicated that the clogs of nozzle consist of Al<sub>2</sub>O<sub>...
