METHOD FOR CONTINUOUS CASTING OF STEEL

摘要

A subject for the invention is to provide a method of continuous steel casting in which although an "immersion nozzle constituted of a refractory material comprising alumina as the main component" is used for continuous steel casting, this nozzle suffers little fusion loss and no alumina deposition thereon and a clean steel casting can be stably obtained. <??>The method of continuous steel casting of the invention uses a combination of a mold powder having a fluorine content lower than 3% by weight and a viscosity at 1,300 DEG C of from 4 P to 10, 000 P and an immersion nozzle constituted of a refractory material comprising alumina as the main component (e.g., an alumina refractory and/or an alumina-carbon refractory). <IMAGE>
