Technical Field

The invention belongs to the technical field of coal charging and cover uncovering in steel coking, and particularly relates to a coal charging hole cover uncovering device of a top-loading coke oven and a using method.

Background

The coal charging car charges the blended coal into the carbonization chamber through the coal charging port at the top of the furnace for sealing coking, and the coal charging port is sealed by the coal charging hole cover after the coal charging is finished. The coke oven with the size of 7.63m is provided with 4 coal charging hole covers per carbonization chamber, each coal charging hole cover has the thickness of about 124mm, the diameter of a large circle of about 650mm and the mass of about 140Kg, as shown in figure 1, wherein the weight of the furnace cover body is about 131Kg, the weight of the positioning seat is about 3.5Kg, and the weight of the filling material is about 5.5 Kg.

The uncovering of the coal charging hole cover in the normal production process of the coke oven is automatically completed by an uncovering system of the coal charging car, but the cover uncovering system of the coal charging hole cover is used in a high-temperature and severe environment for a long time, so that the cover uncovering system of the coal charging car has frequent faults. The operation time of the single-hole coking chamber of the coke oven is 10-12 minutes, and once the cover uncovering system of the coal charging car fails, the cover uncovering operation of the coal charging hole cover can be carried out only by an operator.
