Electromagnetic Stirrer (EMS) for melting furnace

Working Principle
It' s a stirring equipment of no-touch type which adopts the principle of linear Motor. When fed two phrases AC power to EMS, it shall produce traveling wave field, which thus produces induced electromotive force and then arises induced voltage (right-hand rule). Under the mutual function of the current and the field, a magnetic force occurs which shall push molten metal to move.
Application
This kind of EMS is mostly installed under or beside furnace to produce Aluminium or Al alloy. It can be also used in LF or EF furnace to mix ingredients control temperature precisely.
Questionnaire for EMS for Aluminium
Please provide following information of Al Furnace:
1. Capacity of Al furnace;
2. Depth of liquid Al in the furnace (or: Level of liquid Al);
3. Wall Thickness of Furnace bottom;
4. Is there space provision for EMS under the furnace bottom?
5. Electrical data: current, voltage, etc.
