High-coking-chamber top-mounted coke oven with combined oven door lining blocks

Abstract

The invention discloses a high-coking-chamber top-mounted coke oven with combined oven door lining blocks. The coke oven comprises a coke-side oven door and a machine-side oven door. The lining blocks are mounted on the coke-side oven door and the machine-side oven door. The high-coking-chamber top-mounted coke oven is characterized in that each lining block comprises a head block, a tail block and a plurality of connection blocks between the head block and the tail block; the head blocks, the connection blocks and the tail blocks are arranged in the shape of strips sequentially; the block thickness from each tail block to the corresponding head block is increased from small Dj to large Da, and accordingly, the cross section of an inner cavity of a high coking chamber is in the shape of a trapezoid. After 10 years of operation of an oven body, an oven body heat engineering system starts to age, and coke pouring conditions deteriorate; after use of the designed oven door lining blocks, height stability of finished coke cakes is improved effectively, impact of door-free production of the coke oven is resisted, and the problem of coke cake collapse of the coke oven is solved.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a top-loaded coke oven with a combined furnace door lining brick. Background technique [0002] After entering the new century, coke ovens have adapted to the coke needs of large-scale blast furnace construction, and the production capacity and furnace type have undergone great changes. At present, the coke ovens with a carbonization chamber below 6 meters are basically obsolete furnaces, and the coke ovens above 7 meters are in the Coking enterprises have been widely used. Since the two 7.63m coke ovens of the company have been put into operation, coke-side coking has often occurred and is very serious, which has brought great difficulties to stable coking production. After investigation and analysis, coke ovens with high carbonization chambers are easier Inverted coke, the analysis is mainly due to two factors: 1) The coke cake height of the coke oven ...
