一、炉型设计(一)碱性侧次转炉涡鼓式内型的特点:(1)采用涡鼓式内型首先是解决了风管的平行排列,风力的行程相等,能以等速到达对面炉壁而盘转,使风量能均匀的散布,脱磷反应迅速,炉壁不易被侵蚀。(2)炉子内型大部分呈长方形,风管系平型排列,当铁水量增加时,其容积及风管只数都较圆筒式的容易增大。(3)涡鼓式内型具有极高的去磷能力,它可以吹炼含磷低的生铁,也可以吹炼含磷在2%左右的高
First, the furnace design (a) alkaline side of the vortex drum type converter features: (1) The first use of the vortex-type duct is arranged parallel to the wind pipe, the wind stroke equal to be able to reach the same speed Opposite the furnace wall and disk, so that the air volume can be evenly distributed, dephosphorization reaction quickly, the furnace wall is not easy to be eroded. (2) Most of the stoves are rectangular in shape, and the air ducts are arranged in a flat pattern. When the amount of molten iron increases, the volume and the number of air ducts only tend to increase compared with the cylindrical ones. (3) Whirlpool-type interior has a very high ability to dephosphorization, it can blow low phosphorus pig iron, phosphorus can also be blown around 2% in the high
