300*300*900 Metal vacuum sintering furnace used for vacuum
annealing treatment of carbon sensitive alloy
Equipment brief introduction
The metal sintering furnace is single-chamber, horizontal and
periodic heating structure.It adopt high temperature
molybdenum-Lanthanum alloy heating element.In addition, there are
multiple heating units, each of which controls the temperature
separately. The equipment is used for vacuum and high temperature
degassing sintering of high density alloys, tungsten-nickel alloys,
tungsten-copper alloys, titanium alloys, magnetic materials, etc.It
can also be applied to vacuum heat treatment process of other rare
metal materials. The whole process is controlled by automatic and
manual dual-mode control, monitoring, tracking, self-diagnosis
simulation, display and recording.
Application
Used for vacuum annealing treatment of carbon sensitive alloy such
as high specific gravity alloy, tungsten nickel alloy, tungsten
copper alloy, titanium alloy, magnetic material, etc.
Equipment composition
It is mainly composed of furnace body (shell, door, door clamping
mechanism, furnace door supporting hinge, heating body, heat
insulation screen, charging platform, etc.), vacuum system, water
cooling system, pneumatic system, rapid cooling system, charging
and discharging system, PLC program control, electrical control
cabinet, etc.
PLC, industrial control computer (PC) control to achieve the whole
process of one-click start, real-time dynamic monitoring.The
computer saves temperature, pressure, vacuum and other
parameters.It also has safe and reliable alarm interlock.

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.
