Induction Melting Glass
Description
Induction melting glass furnace with IGBT Induction Heating Equipment
Objectiveļ¼Ā To heat a metal susceptor vessel to 2200Ā°F within 25 minutes for aĀ fiberglass melting application
Materialļ¼Ā Metal susceptor vessel
Temperature ļ¼2200Ā°F
Frequencyļ¼300 kHz
Equipmentļ¼DW-MF-70kW RF Induction heating power supply, remote heat stationĀ and a specially-designed induction coil.
Process:Ā A specially-designed induction coil, shaped to conform to the metalĀ vessel, was used to deliver uniform heat to the vessel. Initial testsĀ were conducted to establish a heating pattern and time-to-temperature.Ā RF induction heating power was applied for 11Ā minutes and the vessel reached a
temperature of 2,200Ā°F. An additional 3kW power supply wasĀ suggested for use when the glass in the vessel is emptied through theĀ drain tube.
Results:Ā Uniform and repeatable results were achieved with the DAWEI induction heatingĀ power supply and coil. The vessel can be maintained at 2200Ā°F so thatĀ glass can be melted for fiber drawing.
