Sinter-HIP furnace is used for debinding of high-performance hard
alloy materials (it can realize the multiply process
Main application
It is used for debinding of high-performance hard alloy materials
(it can realize the process of positive and negative pressure
dewaxing, and the forming agent is paraffin, PEG or rubber),
hydrogen discharge, vacuum sintering, partial pressure sintering,
pressure sintering, rapid cooling and other batch production
operations and research and development operations in the
laboratory.
Total requirements
The cemented carbide pressure sinter-HIP furnace is single chamber,
horizontal and periodic heating. It adopts low voltage and large
current graphite electric heating element for heating. It has
several heating units, each of which controls the temperature
separately.It has debinding function,which can achieve the positive
and negative pressure of two removal processes, molding agent for
paraffin, PEG or rubber).Moreover,it also can realize hydrogen
discharge, vacuum sintering, partial pressure sintering, sinter-HIP
and rapid cooling functions. The whole process by computer
automation control, monitoring, tracking, fault self-diagnosis
simulation display and record.
The sinter-HIP furnace shall include control system, heating
system, debinding system (positive and negative pressure
debinding), vacuum system, partial pressure sintering system,
pressure sintering system, cooling water system, rapid cooling
system, auxiliary system and safety system, etc., with graphite
inner structure built into the insulation cylinder.On the whole, it
must meet the strict requirements of temperature uniformity and
atmosphere uniformity in the sintering process of high performance
cemented carbide.Furnace structure design is advanced and
reasonable, easy to operate and maintain.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 mass production requirements.At the same time, the
equipment should also meet the national requirements of energy
conservation and environmental protection.
