Description

Technical Field

[0001] The invention belongs to the technical field of coke oven maintenance, and in particular relates to a method for reinforcing a steel beam of a coal loading car for removing a five-hole carbonization chamber of a coke oven online. Background Art

[0002] The 7m top-loading coal-type coke oven body is approximately 100*16*14 meters long, wide and high. The furnace body is made of refractory bricks and has 50-60 coke carbonization chambers arranged horizontally inside. The service life is about 20-30 years. During the production process, when the refractory brick masonry on both sides of the carbonization chamber is severely worn and damaged, it needs to be dismantled and renovated. Usually, the roof-lift method is used to dismantle and renovate the refractory bricks from top to bottom, hole by hole, and then re-build the bricks. The width of a carbonization chamber is 1.3m. Due to the repeated operation of heavy coal-loading cars on the top of the coke oven, the span of the lower part of the coal-loading car track steel beam is limited. Currently, the refractory wall of one or two carbonization chambers is usually removed at a time, and the span of the steel beam is within 2.6m. Longitudinal reinforcement beams are installed on both sides of the top of the rail beam for reinforcement.

[0003] During the production process of the coke oven, when the refractory bricks in the carbonization chamber are worn and damaged, the combustion chamber walls on both sides of the carbonization chamber of the furnace body need to be dismantled and renovated. When the coke oven is old and generally damaged, it may even need to be mostly or completely dismantled and renovated.

[0004] To avoid the complete dismantling of the coke oven body and its equipment and piping, minimizing disruption to coke oven production and enabling ongoing dismantling and repair, the current method involves removing and repairing the carbonization chambers one by one, or every two, during the coke oven's operation. Due to the repetitive movement of heavy coal-loading cars weighing up to 200 tons atop the coke ovens, the clearance span of the lower rail steel beams is limited. The current approach involves only removing the refractory walls of one or two carbonization chambers, limiting the clearance span to less than 2.6 meters. Vertical and horizontal beams are then installed at the coke oven's top for reinforcement. Existing methods in the industry face the challenges of multiple demolition and repair batches, long construction times, high working temperatures, and low efficiency.

[0005] Therefore, the known coke oven carbonization chamber roof removal and repair method has the above-mentioned inconveniences and problems. Summary of the Invention
