Vacuum Heat Treatment and Sintering

Vacuum Hardening, Tempering
Vacuum heat treatment of tool steels and other metals in vertical and horizontal batch furnaces

Vacuum Case HardeningVacuum carburizing and high pressure gas quenching in MonoTherm, DualTherm, ModulTherm and SyncroTherm furnaces Vacuum Sintering, Sintering in vacuum or under high pressure (HIP) up to 100 bar.

Vacuum Chamber Furnace Monotherm

The vacuum chamber furnace type

MonoTherm® has broad capabilities and can be used in a wide variety of heat treatment processes like:
• Annealing
• hardening
• tempering
• brazing
• case hardening
The vacuum processing is especially useful for the treatment of high- and medium-alloyed steels. The heating can be convective or in vacuum. For quenching, inert gases are being used. With additional devices, the furnace can be modified for other processes, such as vacuum carburizing.

Vacuum Arc Remelting (VAR)

VAR Features:
• Ingot diameters up to 1,500 mm
• Ingot weights up to 50 tons
• Electrode is melted by means of a DC arc under vacuum (electrode negative, melt pool positive);
• Remelting currents up to 40 kA
• Vacuum range: 1– 0.1 Pa (some applications up to 1000 Pa)
• Electrode weighing system
• Coaxial high current feeding system
• Computer controlled remelting process according to remelting recipes (arc gap control, melt rate control, data acquisition system, print-out of melt records

Powder Metallurgy

Inert gas atomization, combined with melting under vacuum, is the leading process for the production of high-grade metal powders which have to meet specific criteria such as:
• Spherical shape
• High cleanliness
• Rapid solidification
• Homogeneous microstructure

• Ni-base superalloys for the aviation and power engineering
• Solders and brazing metals
• Wear-protection coatings
• MIM powders for components
• Sputter target production for electronics
• MCRALY protection coatings
