Abstract
A lightweight self-sealing flexible door for closing the end of a horizontal coke oven, which door comprises an outer assembly that includes a thin flexible plate and an inner plate assembly that extends into the oven and is supported by the outer assembly. Self adjusting pressure-distributing means associated with the exterior of the flexible plate continuously exert pressure at a plurality of spaced locations adjacent the outer periphery of the flexible plate to cause it to freely flex and urge sealing means adjacent the inner periphery of the flexible plate to substantially sealingly engage the surface of the frame of the oven as the frame is caused to warp and distort by the thermal cycling that occurs during operation of the coke oven. Latching devices hold the door in position against the oven frame and apply pressure upon the pressure-distributing means.
