摘要

采用一级电熔镁砂85%、石墨15%的镁碳材料，加入3%Al/Mg(60/40)抗氧化剂，以固体、液体酚醛树脂为复合结合剂，按合理颗粒级配比所研制的镁碳出钢口砖用于抚钢2座60t超高功率电弧炉出钢口，使出钢口使用寿命由约110炉次提高到约150炉次，满足了使用要求

Abstract

With basic material -85% first grade magnesia + 15% graphite

adding % Al/Mg(60/40)antioxidant

using solid and liquid phenolic resin as binder and making up according to reasonable grain grading

the magnesia-carbon taphole brick for two sets of 60 t ulra-high power electric arc furnace(UHP EAF)at Fushun Special Steel has been developed and was in service.The service life of taphole of developed brick increased to about 150 heats from original about 110 heats
