Abstract

The material to be processed through a furnace is carried on skid rails by sliding shoes. In order to reduce the friction between the skid rails and the sliding shoes, and the breakaway forces at the start of the pushing motion, slip plates are fitted in shallow recesses in the top of the skid rails.
