鞍钢第三炼钢厂平炉蓄热室原采用粘土格子砖砌筑,使用寿命低(平均使用寿命6个月),中修一次耗用粘土格子砖120吨,需用650个工,劳动条件差,耐火材料消耗大,满足不了生产需要。为此三炼钢厂与耐火厂协作,进行科研攻关,试用矾土水泥大格子砖代替粘土格子砖,取得了明显效果。该厂于1976年5月27日在21号平炉试用大格子砖,使用寿命已达
Anshan Iron and Steel Furnace Furnace Furnace flatbed regenerator used in the original clay brick masonry, low life expectancy (average life of 6 months), the repair of a clay brick used 120 tons, 650 workers needed, poor working conditions , Refractory consumption, can not meet the production needs. To this end, the third steelworks cooperated with the refractory plant to carry out scientific research and try out the obvious effect of replacing alumina clay lattice brick with alumina cement large lattice brick. The factory on May 27, 1976 in 21 flat furnace trial large grid brick, the service life has reached
