在高爐生產(chǎn)時(shí),由于初次堵口時(shí)壓炮過猛或開口時(shí)鉆桿對(duì)位不正不在鐵口孔道中心,造成泥套局部破損或孔道偏移,影響正常的出鐵。
我公司生產(chǎn)的泥套澆注料是以高鋁質(zhì)骨料和活性高嶺土粉料及中溫瀝青和碳化硅加優(yōu)質(zhì)碳粉再加入結(jié)合劑制成的泥套泥,泥套澆注料主要用于高爐鐵口部位,做成泥包和泥套,具有較高的穩(wěn)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.
