在高炉生产时,由于初次堵口时压炮过猛或开口时钻杆对位不正不在铁口孔道中心,造成泥套局部破损或孔道偏移,影响正常的出铁。
我公司生产的泥套浇注料是以高铝质骨料和活性高岭土粉料及中温沥青和碳化硅加优质碳粉再加入结合剂制成的泥套泥,泥套浇注料主要用于高炉铁口部位,做成泥包和泥套,具有较高的稳定性和抗震,抗渣性能。
During the blast furnace production, due to excessive pressure during the initial plugging or the misalignment of the drill rod during the opening, the mud jacket was partially damaged or the tunnel was displaced, affecting normal tapping. This product is made of high alumina aggregate and activated kaolin powder and medium temperature asphalt and silicon carbide high quality carbon powder with binders. It is mainly used in blast furnace iron parts to make mud packs and mud jackets. High stability and shock resistance.
