补炉砖采用各种级别的烧结镁砂、电熔镁砂、沥青、石墨为原料,经摩擦机压制成型一定的尺寸。主要修补于转炉的前后大面上,可显著提高转炉炉龄。
Patching furnace bricks take various gra- des of fired magnesite sand, electric magnesium sand, pitch, graphite as the materials, and then be sized accordingly by friction presses. If therepairing lining is at the main front and back main surfaces of a converter, the service life of the converter can be greatly improved.
