5518 Partial Pressure Sintering for silicon nitride,aluminum
nitride,silicon carbide
Vacuum protective atmosphere heat treatment method to the choice of
gas filling. When using the partial pressure of heating vacuum heat
treatment back filling gas should choose the neutral or inert
gases, high purity hydrogen, helium, nitrogen and argon gas, such
as common gases, four gas cooling speed from fast to slow, in turn,
for hydrogen, helium, nitrogen and argon. In the air as the cooling
speed of 1, the hydrogen, helium, nitrogen, argon and air cooling
speed ratio of 7, 6, 0.99, 0.7, respectively. Under any pressure,
hydrogen has the maximum heat transfer capacity and maximum cooling
speed, can be used for graphite as heating and insulation
components of vacuum furnace. But, for high carbon steel grade, the
cooling stage of high temperature (above 1050 ℃) may cause slight
decarbonization; Used for high strength steel has the risk of
hydrogen embrittlement. Using hydrogen as coolant supply system
should be sealed and reliable, complete cooling after operation,
should be timely discharge of hydrogen, and filling the nitrogen,
may open the oven door, otherwise, has caused the risk of
explosion.

• Design standards
The equipment is designed in accordance with the pressure vessel
requirements of the Quality and Technical Supervision Bureau, and
is qualified after pressure testing and shipped. The electrical
design and construction meet national standards.
• Installation pre-test and pre-acceptance
The equipment is fully assembled in our factory, including all
pipelines, vacuum pipelines, process gas pipelines, cooling water
pipelines, compressed air pipelines, etc. Pre-testing can be
carried out after installation. At the customer site, pipelines
other than the equipment are provided by the customer. The
installation also includes the connection of all cables. At the
customer site, the main cable connecting the power cabinet is
provided by the customer. After installation, we conduct vacuum and
positive pressure leakage tests on the entire equipment, as well as
mechanical and electrical function tests.
• Disassembly and transportation
The equipment will be disassembled in several large parts, packed
in a standardized manner, and loaded into the transport vehicle.
• Customer site installation and commissioning
The Redel after-sales engineer will lead the team to complete
commissioning, product trial burning and other work within 20
working days. The customer needs to make appropriate preparations
and provide the necessary tools, such as hoisting and lifting
equipment. And provide installation personnel support (it is
recommended to have 1 mechanical personnel and 1 electrical
personnel).
