1.门吹法(由炉门口向炉内吹割化料)缺点 在熔化末期,尤其全部采用低碳金属炉料配加焦炭或废电极冶炼低碳钢时,出钢口的两侧及上部炉料被泡沫渣遮盖看不清,致使在吹割料时往往遗漏,易造成塌料、火焰大喷、被迫停电抬电极、抬炉盖,使得大量热渣和部份钢水外溢,有时还会发生炉盖爆炸,造成设备和人身事故。换句话说,“门吹法”存在热损失大和浪费电能多的问题。
1. Door blowing method (blowing furnace from the furnace mouth to cut material) Disadvantages At the end of the melting, in particular, all with low-carbon metal charge with coke or waste electrode smelting low carbon steel, tapping the sides and the upper charge Foam slag cover can not see clearly, resulting in the blowing material is often missing, easily lead to collapse material, the flame spray, was forced to power lift the electrode, lift the furnace cover, making a lot of hot slag and part of the molten steel spills, and sometimes furnace lid Explosion, resulting in equipment and personal accident. In other words, “door blowing method” has the problem of large heat loss and waste of electric energy.
