Large Vacuum Sintering Furnace Constant Temperature Field Optimization Design
Vacuum Sintering Furnace is specially adapted to the automated production equipment of silicon carbide pressureless (normal pressure) sintering. The equipment adopts the constant temperature field optimization design, which has the functions of removing the forming agent-vacuum sintering-pressureless sintering in the furnace once. The furnace can adapt to various atmospheres and is suitable for the production of silicon carbide and silicon nitride. The process is simple, the pressure in the furnace, the vacuum and the atmosphere are effectively and accurately controlled. The temperature field in the furnace is uniform and the design of the sintering chamber is reasonable. It is an advanced ultra-high temperature sintering equipment capable of sintering without pressure and low vacuum.
