Abstract：Rational gas distribution is the primary factor for blast furnace to maintain the stable production with high efficiency and low consumption. The gas distribution is affected not only by the qualities of burden and operating rules，but the inner profile of blast furnace. As the innate factor，the rational inner profile design is the basis of acquiring the ideal gas distribution. Depending on the theories of heat transfer and hydromechanics，mathematics models of heat transfer and gas flow in blast furnace were established，and the critical parameters were obtained through experiments. Subsequently，the effect of bosh angle，shaft angle and equivalent bosh angle on the gas distribution were studied through numerical simulation method. The result indicates that decreasing bosh angle and increasing shaft angle are in favor of suppressing the edge flow. And adjusting the equivalent bosh angle can achieve the same destination as well，but which plays a role with higher intensity and wide range compared to the bosh angle adjustment，also with a different maximal affecting position to gas flow.
