STRUCTURE OF REFRACTORIES IN DISCHARGING PART OF MOLTEN STEEL

摘要

The present invention is to improve the dissolution of the disassembly formed in the region where the molten steel is tapped refractory tundish , etc. and in that the tapped portion of the refractory structure which can minimize the discharge of waste , the nozzle is formed in a cylindrical shape with kite tapping the molten steel in the tundish inner sphere side , and the nozzles are arranged in a circle on the outer circumference with the lead , the nozzle kite below provides mingjae having a side slope . ;
