500*520*1900-low pressure sinering furnace mainly applied in
different types of cemented carbide
Main application
The pressure sintering furnace is mainly used for the main
functions of H2 dewaxing under micro-positive pressure of cemented
carbide,dewaxing under negative pressure of argon,vacuum
sintering,argon static and dynamic sintering under low
pressure,argon pressure dendenization,charged
cooling/holding/heating under high temperature and high
pressure.Each furnace program automatically check whether the
graphite heating element is normal;Check safety interlocking
conditions;The insulation door is not opened when the fault occurs
during the dewaxing stage,and the function of positive
pressure,micro positive pressure and vacuum leak detection,purge
the dewaxing tube and heat recovery after fault recovery can be
realized.
Main description
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. The equipment should implement automatic control
of sintering temperature,vacuum degree, pressure,hydraulic pressure
and other working processes of pressure furnace, monitor the
temperature of furnace door,furnace chamber and dewaxing tank, and
drive and control and monitor the state of key components and the
position of valves.With dynamic interlocking,permission management,
parameter curve,historical data, energy consumption
information,heat loss,event records,fault analysis records and
other functions;Historical data must be stored for at least 12
months.The equipment has good safety performance and does not
pollute the environment or harm human health.

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 commissioning,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.
