ABSTRACT OF THE DISCLOSURE A process of treating the engaging portions of steel coke oven doors and jambs that consists essentially of the steps of cleaning said portions of said doors and jambs to the bare metal, penetrating a liquid suspension of micro micron particles of graphite into said portions, said liquid suspension including at least 5% to 25% micro micron size particles of graphite, applying enough of said liquid sus- pension of graphite to form a smooth covering coating on said metal portions and building up sufficient excess of graphite on said portions to effectively seal a door to a jamb during operation of an oven. This invention is distinguishable from others by reason of the process using micro micron particles of graphite in a liquid carrier that enables the graphite penetration of the coke oven doors and jambs to build up a smooth coating. -2-
