500*500*1800-10MPa siner-HIP furnace can realize hydrogen
micro-positive pressure and argon negative pressure debwaxing
Equipment system
It mainly includes control system, heating system, degreasing
system (positive and negative pressure degreasing), vacuum system,
cooling water system, rapid cooling system, safety system and
auxiliary system.
Design criteria
The vacuum degreasing sintering integrated furnace is a single
chamber, double door horizontal and periodic heating structure.The
design is easy to load and unload and maintain, and the whole
process is controlled automatically.Realize full load continuous
operation, 300 furnace times/year or 300 working days/year.Graphite
element resistance heating (low voltage, large current);With a
plurality of heating units, each unit is independently controlled
temperature;Automatic control function, safety interlock function,
the whole process by computer automatic control, monitoring,
tracking, fault self-diagnosis simulation display and record.PLC,
industrial computer (PC) control to realize the whole process of a
key start, real-time dynamic monitoring, computer temperature,
pressure, vacuum degree and other parameters to save, safe and
reliable alarm interlock.
General requirements of equipment
Mainly used for carbide, ceramic materials, wear-resistant
materials, high temperature alloy Ar, H2 carrier gas degreasing,
vacuum sintering, partial pressure sintering (static, dynamic),
vacuum cooling, rapid cooling and other processes.It meets the
strict requirements of furnace temperature uniformity and
atmosphere uniformity in the sintering process of the product. The
furnace structure design is advanced and reasonable, which is
convenient for operation and maintenance.The main supporting
components (control components, sensors, graphite heating element,
thermocouple, main control valve, vacuum pump, etc.) have the
current international advanced level, can adapt to the long-term,
stable, reliable mass production requirements.At the same time, the
equipment to meet the national energy saving, environmental
protection requirements.

boat.The buyer shall provide the furnace control plate and program,
and the seller shall confirm.Cobalt magnetic field: test cobalt
magnetic field after dewaxing, deviation range: ≤±0.3%;Coercive
force: deviation range: ≤± 0.4kA /M.The uniformity of furnace
temperature is the standard of the uniformity of coercive force. |
After sales
1.Installation, Commissioning And Acceptance
We do installation, commissioning and acceptance in buyer's
plant.During the installation and commissioning period, the
commissioning personnel shall be provided free of charge by the
demander according to the staff standard.
The equipment shipped to the buyer, the seller received the buyer's
notification, both within a week to carry the equipment out of the
box together, then check the equipment and all components according
to the packing list . Including equipment accessories, spare parts
and special tools, attached manual and technical documents, etc. It
can be installed after the acceptance check of equipment.
After installation and debugging, the equipment shall be accepted
according to the technical accessories.
2.Training
When taking-over the Furnace to the customer, We will give a staff
training to customer. The operating personnel of the customer
should join to commission,test the furnace, when installing at
customer’s company.
This is practical operation training and practical maintenance
training,and our technical personnel will telling the basic
principle,equipment maintenance knowledge,And the common fault
handling measures.We can training 2 ~ 3 workers. ( Training how to
maintenance and operating.)
3. Warranty period
The warranty period of the equipment is 12 months, which starts
from the date of installation and debugging of the supplier.
Equipment failure happens, after-sales service personnel shall give
solutions within 2 hours, after receiving the buyer's notification
. If it is need to go to the site for treatment , operators
dispatched by seller should arrive at the site within 48 hours
after go aboard. In case of emergency,operators should arrive at
the site within 48 hours after go aboard, and continue to make
repairs until the fault is removed and the equipment returns to
normal.
