This tube furnace (photo) provides fast cycle times under protective gas and vacuum, making it suitable for heat treatment of powders and for brazing and annealing processes. The insert tube with a gas-tight end cap is arranged on a sliding frame, enabling samples to be inserted or removed under a protective gas atmosphere into or out of the preheated furnace, which results in extremely short heating and cooling times. The furnace has a maximum operating temperature of 1,100°C. The Inconel heating tube has a 220-mm I.D. and is 1-m long. — Linn High Therm GmbH, Eschenfelden, Germany
