PROBLEM TO BE SOLVED: To provide a coke oven cover that promotes the coking of coal particles fed into the section near the cover of a coke carbonization oven. SOLUTION: The coke oven cover is constructed by providing, inside a coke oven cover structure 3 that opens/closes the entrance 4 of a coke carbonization oven 1, a heat-insulating box 11 and a bottomless emitted gas circulation and isolation chamber 15 formed by providing a plurality of stages of lateral spacer frames 16 beside the box 11, laterally juxtaposing coal particle infiltration block strip plates 17, which are freely movably suspended from the frames 16, on the frames 16 so as to leave small aerating gaps 18 on both sides of each plate 17, and superposing the lower end of each upper plate 17A and the upper end of the lower plate 17B in such a manner that they are slidable on a notched cross section and that a coupling notch groove 20 that directs the oven cover side is provided on one side of the superposed face, and a coupling protrusion 21 which is freely coupled with the groove 20 is formed on the other side.
