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 (IPC) 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.
The equipment can be 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 meets the strict requirement of uniformity of furnace temperature and atmosphere in sintering process of cemented carbide.
