Base structure of coke oven

Abstract

The invention discloses a base structure of a coke oven. The base structure consists of N rows of frames, two boundary beams and a top plate, wherein the top plate is of a structure that longitudinal ultra-long concrete of more than 90m is adopted, and no gap is left; four spans are formed in the horizontal direction, the distances between the frame columns in the spans are equal, and a central line of the middle frame column is superposed with the central line of the coke oven; in the N rows of frames in the longitudinal direction, the front six rows of column frames at the two ends are hinged with a bottom plate, the middle N-12 rows of frame columns are fixedly connected with the bottom plate. According to the base structure of the coke oven, for the condition that the ultra-long concrete structure of more than 90m is positioned in the environment with the average temperature of 110 DEG C, the temperature stress and the seismic stress can be eliminated simultaneously. According to the base structure, the normal operation of the coke oven is met, the production efficiency and the product quality are improved, and the safety and construction feasibility of a base structure system of the coke oven can be ensured. The base structure is simple, advanced in technology, safe and reliable, and can be applied to a coke oven with an oversized volume.

Description

technical field [0001] The invention relates to the technical field of fixed structures, and discloses a basic structure, in particular a coke oven basic structure. Background technique [0002] Large-scale coke oven is the development direction of coking technology. After the founding of New China, the coking technology of the former Soviet Union was introduced, and a coke oven with a carbonization chamber height of 4.3m designed by the former Soviet Union was built in Angang. In 1971, my country's first 5.5m coke oven was built and put into operation in Panzhihua Iron and Steel. In 1985, my country's first 6m M-type coke oven imported from Japan was completed and put into operation in Baosteel. In 1987, the first 6m coke oven JN60 designed by my country was completed and put into operation in Beijing Coking Plant. In 2010, the first 6.98m coke oven designed by my country was completed and put into operation in Bayuquan, Anshan Iron and Steel Co., Ltd. With the advancem...

AI Technical Summary

Problems solved by technology

There is a certain temperature difference between the construction and production of the coke oven foundation roof. In order to solve the temperature stress, the method of adding expansion joints is adopted abroad, which increases the complexity of the furnace body design and structure.
