double door horizontal and periodic heating structure
Equipment function:
Automatic leak detection function
Vacuum sintering function
Ar partial pressure sintering function(Dynamic and static partial
pressure)
Vacuum cooling function
Electrified cooling and thermal insulation function
Rapid cooling function(Put a heat exchanger inside)
Fully automatic control function

Design standards:
The vacuum sintering furnace is a single chamber and double door
horizontal and periodic heating structure,which is designed for
easy handling and maintenance, the whole process is controlled
automatically.It can realize full load continuous operation, 300
furnace times/year or 300 working days/year.It uses graphite
element resistance heating (low voltage, high current) .In
addition, there are multiple heating units, each of which controls
the temperature separately.It equipped with fully automatic control
function and safety interlock function.The whole process is
automatically controlled, monitored, tracked and recorded by
computer.The PLC, industrial computer (PC) control to realize the
whole process of one-key start, real-time dynamic
monitoring,computer will save temperature, pressure,vacuum and
other parameters,alarm interlocking is safe and reliable.
General equipment requirements:
The equipment is mainly used for Silicon Carbide vacuum sintering,
partial pressure sintering, pressure sintering, rapid cooling and
other processes.It can meets the strict requirement of uniformity
of furnace temperature and atmosphere in sintering process of
cemented carbide.The furnace structure design is advanced and
reasonable, easy to use operation and maintenance.The main
supporting components (control components, sensors, graphite
heating element, thermocouple, main control valve, vacuum pump,
etc.) have the international advanced level, can adapt to the
long-term, stable, reliable batch production requirements.At the
same time, the equipment meets the national requirements for energy
conservation and environmental protection.

| It can power the indicator lights and control the furnace when the
power goes out,the time is more than or equal 80 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.
