occur when water or damp gets under the bath surface of molten melts. In the operation of medium-frequency furnaces with total emptying, the danger is somewhat less, since the charging process can be controlled so that any wet or damp charge material can dry out above the melting bath. If water penetrates below the melt, … Continue reading Water vapour explosions

is the term for the outer protective cladding of induction furnace coils, consist- ing of flexible ceramic-organic panels of glass fibre materials. This serves to pro- tect the coil against metallic dusts and spray iron during operation. For safety reasons, no materials or paint coatings may be used that are impermeable to moisture. These would … Continue reading Coil jacket

Coil short-circuit is a short-circuit between 2 parallel windings, which can occur due to an insulation fault. If for example there is too much damp or moisture in the area of the intermediate layers due to inadequate drying, the voltage must be reduced to a low level, so that no leak currents can flow. As … Continue reading Coil short-circuit
