4415 MIM Vacuum Debinding Sintering Furnace For Stainless Steel Material
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.
