This induction melting equipment is specially designed for melting of metals in research laboratories. Melting can be effected either in vacuum or in a gas atmosphere. The design of the furnace permits it to be repeatedly evacuated and flushed with gas. The system evacuation-gas-evacuation-etc., offers great advantages, particularly when melting oxidation-sensitive samples, such as ferro-alloys, with a large area (powder). The oxygen is "washed" away efficiently.

 

The melting furnace is particularly wellsuited for the preparation of.  * Special reference, monitor and settingup  samples for  spectrometric analysis.  * Special samples for testing of raw materials, e.g. scrap and ferroalloys.  * Slag samples via fusion with borax.  * Development of new types of material.  * Melting of powder.

 
 
 The HF-gencrator has a stated effect of 15kW. The generator is sealed into an enclosed cabinet. The structual design consists of aluminium profiles with outer panels an fittings of aluminium. Two sides are fitted with removable shutters with special locks.  The operating controls, instruments and HF-outlets are positioned on the front of the generator, water and power supply connections on the rear. The HF-generator is equipped wilh high and low impedance output tenninals and a high -tension changeover switch. The output effect is continously adjustable by means of a knob on the generator's frontpancl, adjuslinent in the low-impedance range 60-1 00%. A synchronous-motor-driven time relay, adjustable from 0-6, 0-60 sec., 0-6, 0-60 min. and 0-6 hours, is built into the generator.
