摘要
In the iron making process of blast furnace, the size and location of raceway have an important impact on the distribution of gas flow and gas/solid temperature. Based on a one-dimensional cold-state model, the similar geometry model, subarea method and basic force model were employed in this article to derive and accurately calculate the forces of gravity, gas pressure and friction. Combining a three-dimensional cold-state experiment of raceway detection with optical method, a new expression of raceway size with the blast velocity was obtained as well as the modification factor of gas pressure.
