Dingsheng Thermal Dynamics is continuously advancing its R&D capabilities and is currently developing a new-type aluminum nitride (AlN) sintering furnace. The goal is to provide customers with a high-temperature vacuum AlN sintering furnace that offers superior nitridation quality and a long service life.
The new AlN sintering furnace consists of two main parts: the furnace wall and the furnace top. The furnace top features an arch structure and is equipped with corresponding electric heating devices, a nitrogen inlet system, and an exhaust system. The nitrogen inlet system includes a nitrogen input pipe, while the exhaust system includes an exhaust pipe. The nitrogen input pipe enters the furnace chamber from the upper part of one side of the furnace wall through the insulation layer.
This design allows nitrogen to rapidly enter the furnace chamber, ensuring quick and complete nitridation reactions. It improves nitrogen utilization efficiency and guarantees high nitridation quality. The exhaust pipe is positioned to enter the furnace chamber from the lower part of the furnace wall, allowing condensate and waste gases to be efficiently removed, which enhances the vacuum level inside the furnace and ensures nitridation quality.
The arch is constructed from silicon carbide (SiC) arch bricks. These bricks have high strength, long service life, are easy to install, and convenient for maintenance. Additionally, due to the far-infrared radiation properties of silicon carbide, the furnace’s internal heating conditions are significantly improved, enabling rapid electric heating and energy savings.
