小高炉,土高炉因为蓄热少,散热多,直接还原较多,焦比高空气使用多,因之空气在炉内的合理分布更为重要,如风口中心线不交高炉中心线,风量不均,则燃烧不均,会发生炉料偏行,严重时,会发生炉冷和冻结事故,如风口倾角太小,也影响炉温,甚至发生冻结,因之空气的进入和分布工具——风口是高炉的关键部位,它的按装和检查是高炉修建中的重要工序,要特别重视。 Small blast furnace, soil blast furnace because of less heat, heat dissipation, more direct reduction, the use of high coke than the air, so the air distribution in the furnace is more important, such as tuyere centerline do not pay blast furnace centerline, the air volume is not Are uneven, the charge will occur partial deviation, serious, will occur furnace cooling and freezing accidents, such as the tuyere angle is too small, but also affect the furnace temperature, or even freeze, so the air into and distribution of tools - tuyere It is a key part of the blast furnace. Its installation and inspection are important processes in blast furnace construction. Special attention should be paid to it.
