6MPA 400*400*1200 Sinter-HIP furnace
Main application
The sinter-HIP furnace is mainly used for the main functions such
as micro-positive pressure H2 dewaxing of carbide, negative
pressure dewaxing of argon, vacuum sintering, static and dynamic
sintering of low pressure argon, densification under argon
pressure, electrified cooling/heat preservation/heating under high
temperature and high pressure, etc.Each furnace automatically check
whether the graphite heating element is normal;Check safety
interlock conditions;When a fault occurs in the dewaxing stage, the
insulation door will not be opened, which can realize the functions
of positive pressure, micro positive pressure and vacuum leak
detection, purging the dewaxing tube, and continuing heat at the
break point after fault recovery.
Main requirements
Horizontal design structure.The equipment mainly includes furnace
body, hydraulic system, vacuum system, gas distribution system,
high pressure system, dewaxing system, cooling water distribution
system, graphite heating and electrical control system and other
main components.In general, it can meets the strict requirements of
furnace temperature uniformity and atmosphere uniformity in the
sintering process of high-performance cemented carbide.Furnace
structure design is advanced and reasonable, intelligent control
and protection interlock ability is strong.

15 | Cooling time | When the furnace load fully,the sintering temperature cooling from
1450℃ to 100℃ need cost ≤6h(water
temperature≤30℃,55bar≤pressure≤58bar). |
16 | Uninterruptible power supply guarantee time | Power the indicator lamp and control the furnace when the power is
off, the duration is ≥100 minutes. |
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.
