1700°C Tungsten Rod Heated Hydrogen Furnace

High-Temperature Vertical Vacuum Hydrogen Sintering Furnace

The 1700℃ high-temperature vertical vacuum hydrogen sintering furnace is mainly used for high-temperature vacuum sintering and protective atmosphere heat treatment processes of metallic materials, cemented carbides, powder metallurgy, and non-metallic materials. The equipment adopts a vertical single-chamber structure design, consisting of a vertical main unit, vacuum system, gas filling system, water cooling system, and intelligent electrical control system, suitable for high-temperature hydrogen sintering processes.

This equipment uses a high-temperature tungsten rod as the core heating element, featuring good high-temperature stability, rapid heating rate, and high furnace temperature uniformity. The system supports operation in vacuum and hydrogen-nitrogen mixed atmospheres, meeting the high-temperature sintering requirements of high-end materials in reducing atmosphere environments. The equipment is equipped with a high-precision intelligent temperature control system, multiple safety protection systems, and a water-cooling structure, enabling long-term stable operation in a high-temperature vacuum atmosphere environment.

Produit Fonctiounen

1. Maximum Temperature 1700℃, Tungsten Rod Heating Element

Using tungsten rods as heating elements, this method is suitable for sintering processes under ultra-high temperature vacuum or hydrogen atmosphere. Tungsten rods have advantages such as high high-temperature strength and good thermal shock resistance, which can meet the stringent high-temperature process requirements.

2. Vertical Structure, Suitable for Long Workpieces

The equipment adopts a vertical main unit (single chamber) structure, with a heating zone size of D900×900mm and an effective working area of ​​D800×700mm. The vertical design is particularly suitable for sintering long workpieces or vertically placed components, and can effectively prevent high-temperature deformation.

3. Large Loading Capacity, Suitable for Batch Production

The large effective working area volume allows for customized loading capacity based on customer process requirements, making it suitable for large-scale vacuum/hydrogen sintering of materials such as cemented carbide, powder metallurgy products, and special ceramics.

4. Hydrogen/Nitrogen Mixed Atmosphere

The working atmosphere is 70% H₂ + 30% N₂, specifically designed for sintering processes requiring a hydrogen reducing atmosphere. It effectively reduces metal oxides, removes oxygen impurities, and improves material purity and density.

5. Adjustable Vacuum, Flexible Process

The ultimate vacuum is 10⁻¹ Pa, and the working vacuum is adjustable from 10-300 Pa. Vacuum sintering or atmosphere-protected sintering can be selected according to process requirements to meet the processing needs of different materials.

Applikatioun Beräicher

• Hard Alloys and Powder Metallurgy: Suitable for vacuum or hydrogen atmosphere sintering of tungsten carbide-based hard alloys and metal powder compacts. Hydrogen effectively reduces oxides on the powder surface, improving alloy density and mechanical properties.
• Refractory Metals such as Tungsten and Molybdenum: Suitable for vacuum/hydrogen atmosphere sintering of refractory metals such as tungsten, molybdenum, tantalum, and niobium and their alloys. The vertical structure is suitable for vertical sintering of long bars and tubes, preventing high-temperature deformation.
• Fortgeschratt Keramik: Suitable for vacuum or hydrogen atmosphere sintering of non-oxide ceramics such as silicon nitride, silicon carbide, and aluminum nitride. The hydrogen atmosphere inhibits ceramic decomposition, resulting in high-density products.
• Special Alloys: Suitable for vacuum sintering of special materials with strict atmosphere requirements, such as titanium alloys, high-temperature alloys, and magnetic alloys, preventing oxidation and ensuring material properties.
• High-Purity Material Processing: Suitable for vacuum degassing, purification, and annealing processes of high-purity metals and high-purity compounds.
• Research institutes: Applicable to high-temperature experiments and research projects in materials science, metallurgical engineering, powder metallurgy and other related fields.
