Design standards
The precision ceramics sinter-HIP 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
Mainly used in precision ceramics dewaxing (Ar carrier gas dewaxing and hydrogen micro-positive pressure dewaxing), vacuum sintering, partial pressure sintering (static, dynamic), pressure sintering, rapid cooling and other processes.It meets the strict requirements of the uniformity of furnace temperature and atmosphere in the sintering process of cemented carbide, and the furnace structure design is advanced and reasonable, which is convenient for 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 mass production requirements.At the same time, the equipment meets the national requirements of energy conservation and environmental protection.
Technical parameters of equipment
