The pressureless sintering furnace is an intermittent resistance heating furnace. Its main application range is pressureless silicon carbide sintering, cemented carbide, powder metallurgy industry to produce various particle sizes of tungsten carbide powder, chromium carbide powder, titanium carbide powder, vanadium carbide powder and other metal powders and composite metal powders, which are sintered after cold pressing.
It is mainly used in the pressureless sintering of emerging composite ceramic silicon carbide such as silicon carbide sealing rings, heat exchange tubes, sleeves, shaft tubes, nozzles, impellers and bulletproof products.
1. High degree of automation, one-button replacement (vacuuming in the furnace, argon gas flushing process), automatic monitoring of water, electricity and gas throughout the operation process, touch screen simulation can observe the equipment operation status at any time, equipment alarm indication, temperature rise curve, and power on/off operation can all be viewed and operated on the touch screen.
2. Real materials, the furnace body is made of 304 stainless steel, strictly built in accordance with the pressure vessel standards, with good corrosion resistance and airtightness. The insulation materials are all made of high-purity graphite felt, which is durable. All electrical components are reliable brands at home and abroad, and the operation is reliable.
3. High safety, the furnace body is equipped with an automatic explosion-proof valve, which is safe and reliable. The flow switch is installed separately in the sensor part to monitor the water flow in real time. The power supply strictly and effectively sets the overcurrent value and overvoltage value as required.
4. All series of high-temperature vacuum sintering furnaces can realize product dewaxing and sintering integrated molding, which greatly shortens the production cycle of the product.
