Vacuum Sintering Furnace

Process Core: Utilizes medium frequency induction heating principle, specifically designed for ultra-high temperature sintering of refractory alloys (tungsten, molybdenum), cemented carbides, and advanced ceramics. Performance Specifications: Maximum temperature reaches 2500°C, with ultimate vacuum reaching 1×10?? Pa. Equipped with an induction-heated tungsten crucible, ensuring material purity under extreme conditions. Intelligent Efficiency: Horizontal single-chamber structure, supporting both natural cooling and positive pressure rapid cooling modes. Integrated with Siemens PLC and 15-inch touch screen, temperature control accuracy is better than ±1°C, making it an ideal choice for pilot-scale and large-scale production.

Product details

Overview

The vacuum medium frequency sintering furnace is a batch-type induction electric furnace independently developed by Yuanhang Industrial Furnace. It utilizes the principle of electromagnetic induction to directly heat graphite or tungsten crucibles, achieving extremely high energy conversion efficiency. This equipment is widely used for the densification treatment of cemented carbides, superalloys, powder metallurgy materials, functional ceramics, and optoelectronic materials under ultra-high temperature, high vacuum, and protective atmosphere conditions. Particularly for the forming and sintering of refractory metals and their alloys, its performance indicators have reached industry-leading levels.

Technical Features of Yuanhang Vacuum Sintering Furnace

1.Flexible Structural Layout: Horizontal single-chamber design with optional front door or front/rear double doors. The equipment layout is compact, significantly improving loading and unloading efficiency.
2.Rapid Cooling System: Utilizes natural cooling in the high-temperature section and supports forced cooling with pressurized inert protective gas in the low-temperature section, reducing the single-furnace turnaround time by over 30%.
3.Precise Infrared Monitoring: Equipped with far-infrared optical pyrometry components, achieving measurement accuracy as high as 0.2%~0.75%, ensuring the repeatability of ultra-high temperature sintering processes.
4.Fully Automatic Process Management: Features dual-mode operation with program control and manual control. The PLC records all historical process curves, supporting connection to digital factory systems.
5.Comprehensive Safety Protection Matrix: Equipped with complete automatic protection and alarm functions for over-temperature, over-pressure, and water circuit interruption.
