Conclusions
-
1.
A heater has been developed on the basis of infrared radiation lamps for heating moving wire of refractory metals in vacuum.
-
2.
The IR heater is characterized by complete lack of gas liberation in vacuum and also low inertia. This ensures a high heating rate and high speed of the wire (0.4–0.5 m/sec).
-
3.
The IR heater is small, simple, reliable in operation, and is easily installed in any equipment as well as in production lines.
-
4.
The efficiency of the IR heater increases in vacuum due to the higher temperature (300–400° higher) for the same power.
