我厂平炉从生产以来,炉顶温度测量是采用了全辐射高温计,二次仪表用ЭПП—09型电子电位计自动记录,镜头保护装置采用大小两水套和通压缩空气的方法。由于下列几个问题长期未得到解决,因而对生产所起的作用不大。 (1)水套装在炉体后墙上伸入炉内的一端,由于炉温过高经常被烧坏漏水; (2)水套进入炉内端部,口径为100毫米,经常在出钢后补炉期被镁砂白云石堵塞,烧结后,无法通开; I flat furnace from the production, the roof temperature measurement is the use of a full radiation pyrometer, secondary instrument with ЭПП-09-type electronic potentiometer automatically record the size of the lens protection device using two sets of water and compressed air approach. Since the following problems have not been solved for a long time, their effect on production is not great. (1) water jacket in the rear wall of the furnace into the furnace one end of the furnace temperature is often burned due to leakage; (2) water jacket into the end of the furnace, the caliber of 100 mm, often after tapping Replenishment period was clogged with magnesia dolomite, after sintering, unable to open;
