Tube Furnaces

Tube Furnaces

Tube furnaces are widely used in heat treatment processes, including annealing, hardening, and tempering of metals and alloys.

These processes involve heating materials to specific temperatures and then cooling them at controlled rates to achieve specific material properties.

Universal electrical furnaces are designed for the burning of ceramics,  stone mass, thermal processing of small metal particles in the ambiance at the maximum temperature of 900°C, 1260°C, and 1340°C.
