钢锭在均热炉内加热过程中,形成的氧化铁皮通常有一部分脱落在炉坑底部,帽口绝热板和帽口内低熔点渣滓也常常流落在炉内。此外,烧钢操作不慎引起的钢锭表面熔化,炉口砂封槽内砂子的掉入,特别是钢锭靠墙加热时,耐火材料受撞击和高温火焰冲刷 In the soaking furnace ingot heating process, the formation of the oxide scale is usually part of the pit off at the bottom of the hat bonnet insulation board and hat low melting point dregs often also flow in the furnace. In addition, the ingot surface caused by the accidental burning of steel melts, the sand in the sand mouth of the furnace falls into the sand, especially when the steel ingot is heated against the wall, the refractory material is impacted and the high temperature flame scour
