Embodiment

[0029] Such as figure 1 , figure 2 and image 3 As shown, in the coke oven door maintenance method of the present invention, the furnace door to be overhauled is first poured out and placed on the maintenance frame, and the furnace door is rotated 180° by the maintenance frame, and the furnace door is lifted out, and then the furnace door can be lifted for the convenience of subsequent operations. Turn the furnace door 90° so that the lining brick of the furnace door is placed downward; use temporary fixtures such as steel wire rope 14 to bind and connect the furnace door body 1 and the brick groove 11. There is no relative displacement between the furnace door body 1 and the brick groove 11; then loosen the furnace door body connecting bolt 6 and the furnace door brick groove bolt 7, and hang out the furnace door rib 15 and knife edge web 12; After the damaged parts such as the web 12 are repaired, the knife edge web 12, the knife edge 13, and the furnace door reinforcemen...

Abstract

The invention discloses a method for maintaining a coke oven door with higher efficiency. It is different from the common method in that: after the furnace door is exported to the maintenance frame, the furnace door body and the brick groove are fixedly connected with temporary fixing parts, and then the connecting bolts of the furnace door body and the brick groove are loosened; Dismantle, overhaul and reinstall the edge and knife edge webs; remove the temporary fixings after the furnace door body connecting bolts and brick groove connecting bolts are retightened. Since the furnace door body and the brick groove are not disassembled during the overhaul, the overhaul of the often easily damaged knife edge and the knife edge web can be carried out in a targeted manner, which can ensure the quality of the overhaul; at the same time, since there is no need to clean and repair the lining brick Re-installation, no relative displacement occurs between the brick grooves of the furnace door body during the maintenance process, which is convenient for the alignment and restoration installation of the disassembled parts, and can shorten the maintenance time and reduce the maintenance cost, especially suitable for the overhaul of the coke oven door application.

Description

technical field [0001] The invention relates to the technical field of coke oven maintenance, in particular to a coke oven door maintenance method. Background technique [0002] At present, the doors of the machine side and the coke side of the coke oven mostly adopt hanging air-cooled doors, elastic knife edges, and spring door bolts. The advantage of this furnace door is that the alignment position of the furnace door has good repeatability, and the elastic knife edge can always maintain a certain pressure, which effectively prevents the furnace door from emitting smoke and fire. During the production process, the elastic knife edge will be damaged due to collisions and mechanical wear during operation, resulting in smoke from the bolt hole in the brick groove; the web of the knife edge of the furnace door will be fatigue cracked or open welded due to the operation of removing and installing the furnace door, so The overall maintenance and repair of the furnace door must ...
