PREVENCION DE FORMACION DE A1203 EN MODULOS CEIDE Y LOS PARECIDOS

摘要

A lining composition is disclosed for a submerged entry pouring nozzle 10 used in the continuous casting of metals, particularly aluminum killed, low carbon steels. The lining 22 prevents harmful buildup of alumina and other oxides within the nozzle bore 12 which may cause premature nozzle clogging. The nozzle liner 22 comprises a carbon-bonded, SiAlO N-graphite refractory material. Small amounts of antioxidants and additional amounts of less expensive refractory grain or powder are also added to dilute the more expensive siAlON material.
