Abstract

To provide a construction method of a coke oven that can reduce the burden on an operator without using large modular bricks, stack shaped refractories with high precision, and efficiently construct a coke oven. It is a construction method of a coke oven for updating or newly installing a coke oven, and has the following steps: a block manufacturing process of stacking a plurality of shaped refractories at a place other than the construction site of the coke oven to manufacture blocks; a block conveying process, which transports the blocks to the coke oven construction site; a plaster application process, which applies plaster to the position where the blocks are installed; and a block setting process, which installs the plaster to the position where the The above block, the length of the block in the longitudinal direction is not less than 1 / 4 and not more than 2 / 3 of the furnace length of the coke oven, and the height of the block is less than 2m.

Description

technical field [0001] The present invention relates to a construction method of a coke oven used for the renewal of the entire coke oven or a new installation, and in particular relates to an efficient construction of coking by reducing the burden on the operator and stacking shaped refractories with high precision without using large modular bricks. The construction method of the coke oven of the furnace. Background technique [0002] Metallurgical coke used in ironmaking is produced by dry distillation of coal in a chamber coke oven. Chamber-type coke ovens are constructed by alternately arranging carbonization chambers and combustion chambers that supply heat to the carbonization chambers along the furnace width direction, and heat is supplied from the combustion chambers to the carbonization chambers through refractory materials such as refractory bricks that separate the carbonization chambers from the combustion chambers . The chamber-type coke oven includes chamber...
