Abstract
This invention is directed to an extremely lightweight construction for coke oven doors made to provide optimal sealing; the oven door comprises one sealing unit having a seal, and closing forces are applied to act uniformally on the seal, thereby minimizing heat loss between the sealing unit and the coke oven as much as possible. The oven door, on its outside surface, is also provided with a boxed duct structure which in use is vertical and has an open top; the boxed structure facilitates heat dissipation by the door outside surface, by convection air flow in the boxed structure.
