Abstract

The invention discloses a device for replacing furnace column parts above a platform in a coke side furnace. The device comprises a first furnace column, a second furnace column, a third furnace column, the platform in the machine coke side furnace, a chain block and an upper portion fixing large protecting plate device, wherein the third furnace column, the first furnace column and the second furnace column are sequentially arranged on the platform from left to right, the third furnace column, the first furnace column and the second furnace column are fixed together through a furnace column lower portion fixing structure, a first coke furnace large protecting plate is arranged on each of the two sides of the first furnace column, one side, adjacent to the first furnace column, of the third furnace column is correspondingly provided with a second coke furnace large protecting plate, one side, adjacent to the first furnace column, of the second furnace column is correspondingly provided with a third coke furnace large protecting plate, the third furnace column, the second coke furnace large protecting plate and the first coke furnace large protecting plate are tightly connected together through the upper portion fixing large protecting plate device, and the second furnace column, the third coke furnace large protecting plate and the first coke furnace large protecting plate are tightly connected together through the upper portion fixing large protecting plate device. The device is simple in structure and high in replacing efficiency.

Description

technical field [0001] The invention relates to a furnace column replacement device above the platform in a coke-side furnace, in particular to a furnace column replacement device and a replacement method for the part above the platform in a coke-side furnace. Background technique [0002] At present, there are more and more older coke ovens in China, and the older the coke oven, the leakage of the coke oven body and the damage to the iron parts of the furnace will become more and more serious. In particular, the damage to the pillars of the furnace iron parts, due to the long-term high-temperature and high-intensity use environment, the coke oven pillars will have problems such as excessive curvature, partial corrosion, and decreased annealing strength, which can only be replaced by replacing the furnace platform The above part of the furnace column can restore the protective pressure of the coke oven masonry. Contents of the invention [0003] The technical problem to b...
