ABSTRACT:
A coke oven door fabricated from steel plate including a rectangular main door plate having inner and outer planar door faces. A pair of side support plates are rigidly affixed to the main door plate outer surface to extend longitudinally therealong adjacent the side edges thereof and a pair of end support plates are similarly mounted adjacent the main door plate end edges so as to form a door support frame. A plurality of gusset members are symmetrically disposed generally about the midpoint of the main door plate outer face and extend from one of the side support plates toward the other across the main door plate outer face. A sealing ring is affixed to the main door plate inner surface and adapted to sealingly engage a door frame when the door is placed over the coke oven opening. A plurality of fabricated adjusting means are disposed on the outer door face adjacent the side and end support plates with each such means having an adjustment plunger passing through the door plate into communication with the sealing ring. During oven operation and as the temperature inside the oven becomes elevated, the door frame is subjected to heat induced warpage. The sealing ring may then be adjusted through use of the individual adjusting means to close any resulting gaps between the sealing ring and door frame. Thereafter, the door itself will flex under the influence and urging of the conventional door mounting or latching means to compensate for and seal against further door frame warpage. Because of the particular gussetted arrangement utilized, there is very little flexure of the door at the midpoint thereof with primary flexure occurring away from the center toward the outer edges.
