Abstract
The invention relates to a light construction plug for coke oven doors of horizontal chamber coking ovens, consisting of box-like, heat-resistant, metallic hollow bodies which are secured on the door body and can be filled with insulating material of low specific gravity. According to the invention, it is provided that in the longitudinal direction of the chamber, between the door body (1) and the chamber filling (5), one or more detachably interconnected hollow bodies (6, 7) are arranged and that for the formation of vertical gas pressure equalizing channels (10) between the chamber walls (11) and the hollow bodies (6, 7) the lateral outer walls (8, 9) thereof have concavities directed inwardly toward the center of the chamber.
