<P>PROBLEM TO BE SOLVED: To provide an oven shutting structure of a coke oven, which does not allow the total weight of a protection plate, a door frame and a door to always concentrate and act on under-protection plate bricks of a corbel end part. <P>SOLUTION: The chamber-type coke oven 1 is configured such that doors 8 arranged on both ends in the oven longitudinal direction of each of a plurality of carbonization chambers 3 which are alternately arranged with combustion chambers 4 in an oven battery direction are held by door frames 9 attached on protection plates 7 arranged on both ends in the oven longitudinal direction of the combustion chambers 4, and an oven shutting force is imparted in the oven longitudinal direction of the combustion chambers 4 through the protection plates 7 by backstays 6 arranged on both ends in the oven longitudinal direction of the combustion chambers 4. The protection plate 7 is configured to be vertically supported through a spring 14 installed on the backstay 6. The expansion of the bricks are made free during cold and during being heated, and after being heated, a supporting load at the end of the corbel part is reduced to thereby achieve the elongation of the brick life. After being heated, a sealing function can be held by pressing a sealing material, and the gas leakage from the carbonization chamber to outside the oven during coal carbonization can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
