Coke-oven door with Z-profile sealing frame

Abstract

A sealing frame of generally Z-shaped cross-section, extending all around a peripheral flange of a coke-oven door, has an inner rim hugging that flange and a cantilevered web resiliently bearing with a free knife edge upon a door frame of an associated coking chamber. The rim is held against the door flange by recessed clamping plates which are shiftable, together with the sealing flange, in a direction perpendicular to the door opening under pressure of cams on the inner surface of a multiplicity of retaining disks overhanging these plates with shafts rotatably lodged in the door flange. The knife edge of the frame web is further biased toward the door frame by springs lodged in housings that are secured either to the clamping plates or to the sealing frame itself; in the latter instance the ends of the springs remote from the web are engaged by slides in contact with cams on the outer disk faces whose contours conform to those of the inner cams so as to make the spring pressure independent of any plate shift also in this case. The spring housings may be disposed laterally outward of the retaining disks or may be interleaved therewith in the direction of the frame edges.
