Abstract:

A fabricated self-sealing coke oven door which is resistant to warping formed of a rigid steel plate which overlies the mouth of a coking chamber of a coke oven having longitudinal and transverse rectangular stiffener plates welded to the door plate at points spaced inwardly from the edges of the door plate with a plurality of transverse braces weldably interconnecting the longitudinal stiffener plates at spaced points intermediate the ends thereof and welded to the door plates, a plurality of additional transverse braces having one end welded to a longitudinal stiffener plate and the other end welded to the door plate, a rectangular bar welded to the upper edge of each of the stiffener plates extending the length thereof and outwardly to the edge of the door plate in a plane parallel to the plane of the door plate, and a plurality of spring box means at spaced points along the length of each rectangular bar comprising a length of tubing disposed between the rectangular bar and the door plate adapted to co-act through apertures in the door plate with a sealing ring adapted to be mounted on the inner surface of the door plate. At least two of the transverse braces are adapted to support with the door plate a heat resistant plug for the mouth of the coking chamber on the inner surface of the door plate, and two of the transverse braces can be solid rectangular blocks which support door latches which maintain the oven door in operative position at the mouth of the coking chamber.
