ABSTRACT:
The invention is a new design of chuck door which has a knife-edge sealing strip that fits tightly in a slot of the door and is adjustable longitudinally by jacking screws. The strip is locked in position also by screws. The inside of the chuck door is provided with a cavity within which heat insulation refractory material is retained. A pivoted heat shield hangs from extended side heat shields in the coke oven and pivots up to allow entry of the leveler bar through the opening closed by the chuck door. The design is readily adaptable to new and to existing oven doors.
