ABSTRACT:
A device for sealing the cambers of coke ovens adjacent the roof of the oven and above an oven door frame which is located at the transition between fireclay brickwork and silica brickwork each of which has joints between the courses thereof is located between anchor plates which support each side of the door frame. The door frame includes a vertical back portion which intersects a horizontal top portion. During the formation of the brick a cast iron bridge is positioned so that a vertical part is arranged directly behind the door and is advantageously sealed to the rear base of the door frame by a gasket or asbestos cord. The anchor plate carries an upper horizontal portion which is disposed beneath the fireclay brick at the transition between the fireclay and the silica brickwork and supports the fireclay brick. In addition, another horizontally extending part of the cast iron bridge is positioned into the silica brickwork between adjacent courses located near the top of such brickwork. The oven is advantageously constructed also with one or more T-girders which are arranged in the courses in the fireclay brick and in addition at the top of the oven roof an angle iron is positioned on the top of the course of the fireclay brick.
