High Speed Salt Bath Furnaces

High Speed and Tool Steel Heat Treating

Upton high-speed salt bath furnaces serve tool rooms and tool steel heat treating, as well as neutral hardening and carbide brazing.

Submerged Electrode Placement

Only the electrode faces touch the salt; the electrodes themselves take up none of the bath space, so the whole bath stays clear for work.

Conductive Immersion Heating

Parts heat by direct contact with the molten salt, which also supports them in the bath. When the load leaves the bath, a film of salt stays on the surface and slows cooling on the way to the quench.
