Description
Technical Field
The utility model relates to a positioner, concretely relates to wind gap subassembly installation positioner belongs to blast furnace ironmaking technical field.
Background
Blast furnace iron making is still the main process mode of iron making at the present stage, and the stability and the smoothness of a blast furnace are the basis of all economic and technical indexes.
The combustion reaction in front of the tuyere of the blast furnace is carried out in an environment filled with coke, that is, under the condition that the air amount is constant and the coke is excessive, unlike the general combustion process. The combustion reaction zone in front of the blast furnace tuyere is called a combustion zone, the combustion zone is a source of blast furnace gas, the size and distribution of the combustion zone determine the initial distribution of hearth gas and gas, and determine and influence the second distribution and the third distribution of gas flow in the ascending process of the blast furnace to a large extent. The coal gas is distributed reasonably, so that the heat energy and the chemical energy of the coal gas are fully utilized, the blast furnace runs smoothly, and the cost of per ton iron is reduced.
The combustion zone (including longitudinal and transverse) is properly enlarged, the dead area of the furnace charge can be reduced, the active area of the hearth is enlarged, and the whole blast furnace charge column is looser, so that the smooth operation of the blast furnace is facilitated. From the view of the forward movement of the furnace burden, the larger the horizontal projection area of the combustion zone is desired to be, the better the horizontal projection area of the combustion zone is, because the hot air is blown out from the tuyere small sleeve, a forward and upward irregular cone is formed in the furnace hearth, and in order to obtain the larger horizontal projection area of the combustion zone, a downward inclined angle (about 5 degrees) is generally required between the central line of the tuyere small sleeve and the horizontal plane. The water supply pipe of the tuyere small sleeve is positioned right above the tuyere small sleeve, and the lowest point of the water supply pipe which is declined with the tuyere small sleeve is positioned on the central plane of the tuyere small sleeve. The blast furnace tuyere comprises a tuyere large sleeve, a tuyere middle sleeve, a tuyere small sleeve, a tuyere belly pipe and the like, wherein in the installation process, the tuyere large sleeve is positioned on the outermost side, the tuyere small sleeve is positioned on the innermost side, and in the installation process of the tuyere small sleeve, if the position of the circumferential direction moves, the declination included angle between the tuyere small sleeve and the horizontal plane cannot be ensured, so that the horizontal projection area of a combustion zone in front of the tuyere is reduced. In the installation process of the tuyere small sleeve, if the position of the tuyere small sleeve moves in the circumferential direction, the coupling degree of the tuyere small sleeve and the sealing surface of the tuyere belly pipe is reduced, and air leakage between the tuyere small sleeve and the tuyere belly pipe is caused after the blast furnace is rebleed. Therefore, a new solution to solve the above technical problems is urgently needed.
