Vacuum Electric Thermal Installation KB 153 for Hydrogen Sealing Applications

Vacuum electrothermal furnace KB 153 two-cup hydrogen furnace is designed for the production of glass spheres of single and multi-contact germanowires in two gas environments (hydrogen-nitrogen-hydrogen, nitrogen), as well as for soldering of precision parts with silver solders in hydrogen environment at temperatures up to 1200C. The furnace is a gas-filled batch electric furnace with a stationary hearth and vertically moving heating chambers (hoods). Each hood is equipped with two observation windows located at the same level. A separate gas system is provided for each hood to prepare the second hood for operation while the first hood is in operation. The gas system provides formation and dosing of the working gas supply (pure hydrogen, nitrogen or formargaz) into the heating chamber during the technological process, humidification of the gas to the required value. The heater is made of nichrome bars.
