The push plate furnace is a continuous industrial kiln that uses a push plate to transport the raw materials to be fired to the kiln for sintering. The working principle of the push plate furnace is that the materials to be fired are directly or indirectly placed on the high temperature resistant and friction resistant push plate, transported forward by the propulsion system, and finally sintered in the furnace. The push plate furnace has the characteristics of high temperature uniformity and high atmosphere stability, and is suitable for industries such as electronic ceramic materials.
