Abstract

A warp-resistant doorjamb is mounted next to the refractory at the outer end of a coke oven chamber. The doorjamb includes a rectangularly-shaped frame with end segments joining together two side segments each having a length substantially corresponding to the height of the coke oven chamber. Both side segments have an outwardly-extending rigid beam section with openings to releasably engage with hanger bars on a coke oven door. A plurality of web sections extends at spaced-apart intervals from each rigid beam section to define window openings between the web sections to minimize the conductive transfer of heat to the rigid beam section and dissipate heat to the atmosphere. A base plate section extends along the end and side segments and forms a face surface for mounting next to the refractory of a coke oven chamber. The base plate section is divided by transverse slots into individual base segments each joined with at least one of the web sections for the support thereby. Tube members divided by a longitudinal slot are inserted into the gap between the individual base segments to prevent escape of coke oven gas through the slot between the individual base segments. In one embodiment, a seal strip is attached at each side by welds to each base plate section. In a further embodiment, the web sections have slots to support the seal strip along one edge. Fasteners extend through enlarged openings in the seal strip into each base plate section.
