This kind of ceramic plate is suitable for the heat treatment process of aerospace precision parts. The heating area of the vacuum furnace is 900 * 600 * 600mm, and the size of the plate is 900 * 600 * 20MM. This is a single-layer structure. If multiple layers are needed, it can also be designed as a frame structure. Each layer of material tray can load 10kg parts. Due to the light weight of aerospace precision parts, the weight of ceramic plate is also very light. To reduce energy consumption, not only can we install more parts, improve efficiency, but also significantly reduce energy. Our company's non-standard customized vacuum furnace charging tray, charging rack. Special heat-resistant steel material with high temperature resistance over 1300 ℃.
