Abstract

In order to improve the characteristics of MgO-C brick applied to RH lower vessel, several originally-prescribed specimens were prepared by changing the amount of additives with different size distributions. These specimens were tested on their durabilities with an experimental rotary type electric furnace and a practical 2RH in a manufacturing line. Following are the major results:<br>1) Specimens prepared with 3-7% expanded carbon and anti-oxidation agents exhibited excellent spalling durability.<br>2) Specimens containing both metallic Al and metallic Si had higher elasticity than those containing only metallic Al and those with a higher Si content retained excellent durability against corrosion and oxidation.<br>3) Corrosion at a high temperature was suppressed by removing SiC from the low C-content MgO-C specimen.<br>4) Durability against spalling was improved by shifting the size distribution of specimen from fine one to coarse one.
