Coke oven door having profiled sealing diaphragm

摘要

A coke oven door assembly which is engageable in coke oven frame comprises a door body with a sealing diaphragm which has a clamp leg portion which extends substantially parallel to a surface of the door and a free leg portion which extends substantially at right angles to the clamped leg portion. An adjusting element overlies the clamped leg portion and is clamped in position by a clamp assembly which carries a fixed bar in a movable part which bears against the free leg portion and is biased by a spring into engagement with the free leg portion. The free leg portion is adapted to have a knife edge portion at the end thereof engaged against the door frame and any displacement of the door relative to the door frame will be indicated by a change in position of the movable part carried by the clamp.
