How is the Rapid cooling system operating in sintering furnace?
The fast cooling of the pressurized sintering furnace is divided
into two stages. The first stage is to cool down naturally under
the pressure environment, and the heat preservation door is closed;
the second stage is to open the heat preservation door after
reaching the set temperature to make the high pressure in the
furnace. The argon gas passes through the radiator on the furnace
door to quickly take away heat. When the furnace top furnace
temperature or the furnace door radiator temperature reaches the
upper limit, the heat preservation door is closed again, and the
furnace top furnace temperature or the furnace door radiator
temperature drops accordingly. When the temperature of the top
furnace or the radiator of the furnace door drops, when the
temperature is lower, the insulation door is opened again. After
several cycles, the temperature of the furnace top or the radiator
of the furnace door no longer reaches the upper temperature limit,
and the insulation door is always open.
Cycling of inert gas atmosphere through water cooled heat exchanger
The gas is cycled out of the furnace into a heat exchanger and
pushed back after cooling down into the furnace chamber.
For this application, the furnace must be equipped with a roots
pump to be able to cycle the gas through the heat exchanger. After
cooling down the gas the roots pump pushes the cold gas back into
the furnace again, directly into the retort with the load. The
sample is directly surrounded with the freshly cooled gas.
Cycling the inert gas reduces the gas consumption, which lowers the
process costs. Generally, the cool down time of the empty furnace
is reduced by a factor of two using this option. The lifetime of
the sensitive heating elements and insulation will be reduced using
this fast cooling option.
• 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
