A push-plate kiln is a continuous high-temperature sintering equipment, also known as a push-plate furnace or push-plate tunnel kiln. It is widely used in the firing processes of various fields such as ceramics, electronic components, magnetic materials, and new energy materials. Its core principle involves placing the material on heat-resistant push plates, which are sequentially pushed into the kiln by a hydraulic propulsion system at fixed intervals. The material travels with the push plates through the preheating zone, high-temperature firing zone, and cooling zone, completing the entire thermal treatment process.
