冲天炉熔炼过程中，焦炭在一定供风条件下燃烧，供风方式的选择、供风量的大小，直接关系到焦炭的燃烧效率、炉气成分和铁液的质量，因此供风设备的选用和控制调节就显得尤为重要。
冲天炉的调风阀选择的种类较多，通常采用碟阀或闸阀。其中闸阀结构简单，制造方便。因此，冲天炉的调风阀常采用闸阀。闸阀的设计计算主要是为了确定闸阀的阀径、阀杆直径和阀体的相关尺寸及其所使用的材料。

In the course of the cupola-fusion, coke burning with condition of wind. The choice of wind-afford and how strong the wind is were connection the burning efficiency，component of the furnace and the mass of iron directly, so that thus chooses and control were seen more important.
There are so many kind of wind-measure valve in cupola for chosen, usually, two kinds, dish-valve and gate-valve. The design of the gate-valve is to be confirm the sizes or
material, for example, the diameter of the body and stuff.
