转炉炉体一般由炉帽、炉壳(炉身)、炉底3部分组成,为了便于转炉工作时加料、插入氧枪、排出炉气和倒渣,在炉帽顶部设有圆形炉口。炼钢时,炉内温度在1 600℃以上。为延长炉帽的金属壳和炉衬的使用寿命,普遍采用循环水强制冷却的水冷炉口。其优点是减
The furnace body of the converter is generally composed of a furnace cap, a furnace shell and a furnace bottom. In order to facilitate feeding during the converter work, an oxygen lance is inserted into the furnace body to discharge the furnace gas and slag, and a circular furnace mouth is arranged at the top of the furnace cap. Steelmaking, the furnace temperature above 1 600 ℃. In order to prolong the service life of the metal shell and the lining of the furnace cap, the water-cooled mouth forced cooling by circulating water is generally adopted. The advantage is reduced
