Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] for figure 1 The carbonization chamber furnace wall 1 of the melted part 2 shown can be repaired by the following steps:

[0018] First, if figure 1 As shown, the repair personnel wear heat-insulating clothes, heat-insulating gloves and masks, and then remove the door of the carbonization chamber with a coke pusher. The heat shield 4 is vertically pushed into the part to be repaired in the carbonization chamber, and the top of the heat shield is fixed on the furnace frame 5, so that the part to be repaired is surrounded by an inverted "L"-shaped 90-degree heat shield;

[0019] Secondly, if figure 2 As shown, clean the graphite and sundries at the bottom of the furnace, spread the heat insulation blanket 3 and the walkway board, and then stick the heat insulation blanket on the furnace wall to be repaired and the furnace wall 1 around...

Abstract

The invention discloses a process for manually mending the furnace wall of a carbonization chamber. The process comprises the following: (1) a step of fixing a heat isolation rack: according to a mending part, the heat isolation rack is manufactured; the surface of the heat isolation rack is coated by a heat isolation blanket; the heat isolation rack is pushed to the part of the furnace wall needing mending in the carbonization chamber; and the top of the heat isolation rack is fixed on a furnace frame; (2) a step of paving the heat isolation blanket; graphite and impurities on the bottom of the furnace are cleaned up; the heat isolation blanket and a passage plate are paved; and the heat isolation blanket is stuck on the furnace wall to be treated mended and the furnace wall on the periphery of the heat isolation rack; (3) a step of constructing the inside of the furnace of the carbonization chamber: after the furnace walls at two sides are stuck with the heat isolation blanket, no naked fire is determined to eject; and the mending construction is carried out; and (4) a step of detaching and mending a melting loss part. The mending process can carry out mending in the carbonization chamber under the environment of high temperature of 1,000 DEG C around, reduce cost, improve the service life of the coke furnace, does not influence production and is a feasible and effective method.

Description

technical field [0001] The invention belongs to the technical field of coking, and in particular relates to a process for artificially repairing the furnace wall of a carbonization chamber of a coke oven. Background technique [0002] The structure of the coke oven is composed of furnace roof, combustion chamber, carbonization chamber and flue. The temperature in the carbonization chamber is about 1300 degrees Celsius, mainly for coking. The carbonization chamber is mainly for storing coal. During the coking process, the tar and graphite produced adhere to the wall of the carbonization chamber. The long-term accumulation will collide with the entrance and exit of the coke pushing device, and the quality problems of the silica bricks on the wall of the carbonization chamber itself and Unavoidable errors made by the operator during the temperature adjustment process lead to serious melting loss of the silica bricks on the wall of the carbonization chamber. Due to the charact...
