A top-loaded coke oven with high carbonization chamber with combined furnace door lining brick

Abstract

The invention discloses a top-loaded coke oven with a combined furnace door lining brick. The coke oven includes a coke-side furnace door and a machine-side furnace door. Lining bricks are installed on the coke-side furnace door and the machine-side furnace door. It is characterized in that the lining bricks include head bricks, tail bricks and A number of connecting bricks between the brick and the tail brick, the head brick, the connecting brick and the tail brick are arranged in a long strip in sequence, and the brick thickness from the tail brick to the head brick increases from a smaller thickness Dj to a thicker one. The large thickness Da makes the cross section of the inner cavity of the high carbonization chamber trapezoidal. After 10 years of operation of the furnace body, the thermal system of the furnace body began to age, and the coking situation showed deterioration. After adopting the furnace door lining brick designed by the present invention, the high-direction stability of the mature coke cake can be effectively improved, and the production of the coke oven door can be resisted. The impact capability of the operation solves the problem of coke oven coke cake collapse.

Description

Technical field [0001] The present invention belongs to the technical field of refractory materials, and more particularly to a high-carbon-chamber coke oven having a combined furnace door liner brick. Background technique [0002] After entering the new century, the coke oven adapts to the construction of large blast furnaces, and the capacity and furnace type have changed. At present, the coke oven below the carbonization chamber is basically the elimination furnace type, more than 7 meters or more coke ovens. Coking companies have been widely used. The two 7.63m coke oven from the company often appear in focus side reverse focus, which brings great difficulties to stabilize coke production. After investigation, high-carbon chamber coke oven is more likely to Focus, analysis is mainly because of two factors: 1) High-carbon chamber coke oven is high, and the high-directional stability of the coke is different; 2) High-carbon chamber coke oven combustion chamber temperature setti...
