A solid lubricant application procedure is combined in-line with a steel strip processing method which comprises processing steps upstream and downstream of the lubricant application procedure. The latter comprises applying the lubricant material in molten form or as a solution and may include temperature adjusting steps both upstream and downstream of the lubricant material-applying step. The space for incorporating the lubricant application procedure into the steel strip processing line is limited. The strip speed in the lubricant application procedure is synchronized with the strip speed normally attained in the steel strip processing method in the absence of an in-line lubricant application procedure. The steps of the lubricant application procedure are constrained to accommodate the space limits and strip speed synchronization requirement imposed on the lubricant application procedure when it is combined in-line with the steel strip processing method.

An improved process for making metallurgical coke is provided which enables the use of coals that ordinarily do not yield coke of expected stability based on the rank of the coal. The comminuted coal is pretreated by contacting and reacting the coal with a halogenated hydrocarbon liquid, particularly perchloroethylene, and the pretreated coal is thereafter subjected to high temperature carbonization.
