电炉的生产率、钢的质量及成本与耐火炉衬的修筑及维护有密切关系,因此修补炉是一项重要的操作。关于修炉等方面的重要性与操作过程拟不多述,今仅着重对补炉工作方面提出一些意见供各厂参考。目前各厂对筑打炉底、炉墙等都掌握了一些经验,获得了一些成绩,例如采用苏联的先进经验用大块镁砂砖砌筑炉墙,提高了炉墙寿命,缩短了修炉时间。
Electric furnace productivity, quality and cost of steel and refractory lining of the building and maintenance are closely related, so repair furnace is an important operation. The importance of repair furnaces and other aspects of the operation is not much to say, now only focus on the work of the furnace put forward some suggestions for the factory reference. At present, the plants have gained some experience in building furnace bottoms and furnace walls, and have achieved some successes. For example, the use of large magnesia brick masonry walls using the advanced Soviet experience has raised the life of furnace walls and shortened the repair furnace time.
