Embodiment

[0029] As shown in Fig. 1, Fig. 2 and Fig. 3, the coke oven door maintenance method of the present invention first pours out the furnace door to be overhauled and puts it on the maintenance frame, and after using the maintenance frame to rotate the furnace door by 180°, the furnace door Lift it out, and then turn the furnace door 90° for the convenience of subsequent operations, so that the furnace door lining brick is placed downward; use steel wire rope 14 and other temporary fixings to bind and connect the furnace door body 1 and brick groove 11, such as fixing with steel wire rope 14 It should be ensured that the steel wire rope 14 is prestressed so that there is no relative displacement between the furnace door body 1 and the brick groove 11; then the furnace door body connecting bolt 6 and the furnace door brick groove bolt 7 are loosened, and the furnace door reinforcement plate 15 and the knife edge are loosened. Hang out the web 12; after the damaged parts such as the ...

Abstract

The invention discloses a method for maintaining a coke oven door with higher efficiency. The points of the method different from those of the common method are as follows: firstly, after the oven door is introduced on a maintenance scaffolding, a temporary fixing piece is used to fixedly connect an oven door body and brick grooves, and then an oven door body connecting bolt and brick groove connecting bolts are released; secondly, knife edges and knife-edge web plates are disassembled, maintained and reassembled; thirdly, after the oven door body connecting bolt and the brick groove connecting bolts are refastened, the temporary fixing piece is disassembled. The oven door body and the brick grooves are not disassembled and the parts of the knife edges and the knife-edge web plates which are usually damaged are pertinently overhauled during the maintenance process, thereby the maintenance quality can be guaranteed; simultaneously, lining tiles are not required to be cleaned and rebuilt and no relative displacement is generated between the brick grooves of the oven door body during the maintenance process, thereby the method is convenient for contraposition and recovery assembly of various detachable parts, can shorten the maintenance time and reduce the maintenance cost, and is particularly suitable for being applied to the overhaul of the coke oven door.

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 ...
