萍乡钢铁厂314m~3高炉冷却壁结垢严重,在第一代炉龄停炉中修时对炉底炉缸三层冷却壁采用镁砂(炼钢转炉用)高压冲洗,取得了良好效果。冲洗设备由0.04m~3的简易料罐(上下有阀门控制)及高压(0.5MPa)风动输送管道组成。镁砂要筛除泥砂和粗粒部分,取3~5mm 粒级装入罐内。冲洗前冷却壁水管先用压缩空气冲刷吹干,然后通过开、关料罐的下阀门断续地向喷管
The fouling of the 314m ~ 3 blast furnace cooling wall in Pingxiang Iron & Steel Plant was serious. When the first generation furnace was shut down, the three-layer stave of the bottom hearth furnace was cleaned with high-pressure magnesia (steel-making converter) and achieved good results. Flushing equipment from 0.04m ~ 3 simple material tank (up and down a valve control) and high pressure (0.5MPa) pneumatic conveying pipe. Magnesite to remove silt and coarse particles, take 3 ~ 5mm grain into the tank. Rinse before cooling the wall water pipe with compressed air scouring dry, and then through the open, off the tank under the valve intermittently to the nozzle
