Abstract

A pusher plate for use in a pusher furnace includes a shaped guidance groove in its lower surface which preferably has a bow-tie shape with a narrower central section and wider ends proximate the leading and trailing faces of the plate. The groove receives therein a guide rail which is disposed intermediate a pair of slide rails upon which the plate slides. The shape of the groove allows the plate a small amount of lateral rotation to minimize jamming during travel. Adjacent plates pivot upon contact with each other to automatically adjust their orientation during travel through the furnace. The leading and trailing faces of the plates thus contact one another over a larger surface area to reduce damage to the plates by reducing the pressure therebetween.
