However, due to the complex working conditions of the swing area, it is not easy to directly obtain the shape of the swing area through calculation. At present, the shape of the corresponding swing area is obtained by using the cold-state model plus numerical simulation reasoning, but the data obtained by the cold-state model has a large deviation, which makes the swing area The difference between the data obtained is relatively large, and it cannot provide more accurate simulation parameters for blast furnace production.

The invention relates to the field of blast furnaces, in particular to a method for detecting the shape of a rotary area of a blast-furnace tuyere. The detection method comprises the following steps: carrying out thermal state test, single-tuyere numerical simulation and blast furnace multi-tuyere numerical simulation to obtain a more accurate convolute area shape. According to the method, more accurate simulation parameters are truly provided for blast furnace production by detecting the shape characteristics of the rotation area under the test condition through the thermal test, and meanwhile, the size of the blast furnace rotation area is calculated in combination with blast furnace production data numerical simulation, so that the shape simulation of the rotation area is more accurate.
Description
technical field [0001] The invention relates to the field of blast furnaces, in particular to a method for detecting the shape of a blast furnace tuyere swirl. Background technique [0002] The blast furnace tuyere swirl area is the source of heat and energy for the entire blast furnace production, and is an important reaction area indispensable for the stable operation of the blast furnace. [0003] The shape of the tuyere swirl has a great influence on the air flow at the lower part of the blast furnace, the activity of the hearth and the drop of the charge; in addition, the chemical energy and heat energy required for the production of the blast furnace mainly comes from the gas produced by the combustion of fuel in the tuyere swirl. [0004] The size of the tuyere swirl will directly affect the gas distribution in the lower part of the blast furnace, the balanced drop of the upper charge and the heat and mass transfer process in the entire blast furnace. [0005] A chem...
