Chemical vapor aluminizing furnace
Chemical vapor aluminizing is a process that uses active aluminum
chloride to generate aluminum-based coating. After aluminum chloride is reduced by hydrogen, it enters
the surface to be plated through a special gas inlet system and forms inter metallic compounds with
the nickel in the super alloy.
Special work fixture is used in the reactor to make the reactants
evenly distributed in the cooling channel of the turbine blades.

Technical features:
1.The CVI furnace uses multi-zone independent temperature control
with good temperature uniformity, which can ensure that preforms at
different positions in the furnace can be treated evenly.
2.It can reduce pressure fluctuations through intelligent pressure
regulation and provide a stable pressure environment for vapor
deposition reactions.
3.The CVI furnace usually has a fully enclosed deposition chamber
with good sealing effect and strong anti-pollution ability, which
can prevent external impurities from entering and affecting the
deposition quality.
4.Its multi-channel process gas path design can make the flow field
uniform and there is no deposition dead corner, thereby improving
the deposition effect.
• 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).
• Final acceptance
After installation and commissioning, the equipment can be finally
accepted in accordance with the requirements of the technical
contract.
• Training
Our after-sales engineers will provide a systematic and complete
on-site training, including operation, maintenance,
troubleshooting, etc.
• Technical data delivery
To ensure safe operation and equipment maintenance, the following
technical data will be provided to customers:
1. Equipment installation layout
2. User manual
3. Spare parts list
4. Electrical drawings
5. Component manual
