Coke oven foundation structure and coke oven

Abstract

The invention relates to a coke oven foundation structure and a coke oven. The coke oven foundation structure comprises a bottom plate and a top plate; a plurality of frame pillars are arranged between the bottom plate and the top plate to support the top plate; the top plate includes a plurality of top sub-plates arranged sequentially in a first horizontal direction; every two adjacent top sub-plates have an expansion joint. The coke oven foundation structure has the advantages that the integrated top plate structure of the prior art is replaced with a combination top plate structure formed by arranging the multiple top sub-plates in sequence, so that a super-long structure is avoided, construction complexity is relieved, and construction cost is reduced; every two adjacent top sub-platesare provided with the expansion joint, so that temperature stress of each top sub-plate can be released properly.

Description

technical field [0001] The invention relates to the field of coking, in particular to a basic structure of a coke oven and the coke oven. Background technique [0002] The coke oven is the equipment used for coalization to produce coke, and it is the main thermal equipment for coking. In recent years, with the rapid economic development, the market demand for steel and coke has increased rapidly, and the large-scale coke oven is the development direction of coking technology. The structural features of the super-large volume coke oven are: the height and center distance of the carbonization chamber are increased, the number of holes is increased, and the roof of the coke oven basic structure is lengthened. [0003] With the advancement of large-volume coke oven coking technology, the requirements for coke oven infrastructure are getting higher and higher, and the existing coke oven infrastructure inevitably has the following problems: [0004] 1) The roof is formed by cont...

AI Technical Summary

Problems solved by technology

[0004] 1) The roof is formed by continuous pouring. Due to the increase in the size of the roof, the complexity of the construction is increased, and the requirements for the control of the construction process are increased, thereby increasing the construction cost

[0005] 2) Due to the increase in the size of the roof, there is a certain temperature difference between the roof during construction and production, resulting in temperature stress in the roof

In order to eliminate the temperature stress, the existing method is to increase the amount of reinforcement in the coke oven foundation structure, etc. The cost of this method is high and the construction is complicated
