Shijiazhuang IDEA Electric series electromagnetic stirrer

             Electromagnetic Stirrer is composed of AC-DC-AC inverters, inductors, pure water-cooled devices (water-wind type), functional trolley and appurtenances. The function of AC-DC-AC inverters is to convert 50/60Hz industry frequency alternate current (AC) into a 0.5 ~ 5.0Hz, 3-phase low-frequency power. The power through sensor coil, will produce a traveling magnetic field, which penetrating stainless steel plate of the bottom of furnace and lining effect on molten aluminum, make molten aluminum regular movement, finally achieved the purpose of even stirring. By changing the voltage, frequency and phase of the variable frequency power supply, you can change the magnitude and direction of the stirring force.                     The system composition             AC Power Source: through AC-DC-AC inverters frequency conversion way to make single phase or three phase 50 hz frequency power supply converted into frequency adjustable in 5-30 hz, 0-380 - v voltage adjustable phase mutual difference 90 degrees two-phase or 120 degrees power supply to the sensor creating the magnetic field.             Inductor: Sensors is energy conversion components, converts electrical energy into magnetic energy act on metal melt,reach the stirring effect.             Cooling system: By forcing water cooled or air cooled make the system working in a safe environment temperature.             Control and protection system: In addition to the complete system of conventional electric control, for the system to provide more complete electrical protection.             System Introduction             AC Power Source using industrial-grade single-chip microcomputer control and intelligent power module as the core, make three-phase power frequency AC power frequency conversion 5-30HZ continuous adjustable ac power supply to the sensors.             Sensor is mainly composed of three parts -coil, iron core and cooling, the cooling way is direct water cooling or forced air cooling, make the sensor forced cooling, to guarantee the normal work of the sensor. the coil is three-phase coil, coil respectively fixed on the iron core, when the low frequency current through the coil, produces the corresponding magnetic field.             The cooling system such as using closed loop water cooling way, composed of pure water generator, cooling pump station and pipeline, the cooling system configuration water quality, water pressure, water flow, water shortage’s fault detection.                       Range of application             a Aluminum, magnesium alloy experiments stirring             b Semi-solid forming studding             c course of crystallization experimental study              d die-cast formation             e Foam metal forming             f Metal refining mixing
