Equipment system:
It mainly includes control system, heating system, positive and
negative pressure dewaxing system, vacuum system, pressure
sintering system, cooling water system, rapid cooling system,
safety system and auxiliary system.
Design standards:
The cemented carbide pressure 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 dewaxing of cemented carbide
(vacuum Ar carrier gas dewaxing and hydrogen micro-positive
pressure dewaxing), 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.

hours(water temperature ≤26℃,55bar≤pressure≤58bar) |
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.
