4415 MIM vacuum debinding sintering furnace for sintering of
stainless steel material
Equipment system:
It mainly includes control system,heating system,positive and
negative pressure debinding system, vacuum system,cooling water
system, rapid cooling system,safety system and auxiliary system.
Design standards:
The stainless steel 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 stainless steel(MIM),debinding of
cemented carbide (vacuum Ar carrier gas debinding and hydrogen
micro-positive pressure debinding), 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.
