The hottest area of medium and high frequency coreless furnaces is at the mid-point of the power coil. All areas of slag deposit will be at a much lower temperature than those occurring at the center of the coil. Slag can also be deposited in areas midway down the crucible lining, where insufficient metal turbulence from magnetic stirring occurs.

Explanation of a Coreless Induction Furnace – Furnace Cooling

As seen in channel furnaces a stirring occurs. This stirring allows for molten metal to rise upwards. Slag forms along the top and middle layers of the crucible. This differs from the slag build up found in channel furnaces. Channel furnaces form slag in the throat of the furnace above the induction unit. To keep the coil from overheating, it ...

2019-01-30  Slag residuals will deposit themselves along the refractory walls and also within the coil. The type of slag varies depending on the material the furnace is melting. Those at a high melting point can be especially prone to this kind of build-up, at the point where the hot slag makes contact with the colder surface of the refractory wall.

A 10 ton coreless furnace operating at 60 Hz can melt its capacity in two hours. At 275 Hz, the same furnace can melt the full 10 ton charge in 26 minutes, or four times faster. An added advantage of higher frequency operation is that furnaces can be started using less bulky scrap and can be emptied completely between heats. The transformers, inverters and capacitors needed to “tune” the ...
