Abstract

Furnace comprises a reception chamber for the material to be annealed, which consists of fire-proof material, has double walls and is heated and cooled by liquid passing between these walls. Protectve gas is introduced into the chamber. Specifically, quartz is used as fireproof material. The chamber has an extension ending in an oil bath with a separating screen between the lower chamber end and the extension.
