Small experiment of electromagnetic stirrer .

            System Over View:

            1,The system adopts IPM intelligent power module as the core device, itself has a short circuit, over-current, overheating, under-voltage protection function, in the design of the system add a reliable buffer circuit and other anti-interference circuit.

           2,Using industrial-grade single-chip computer as core control, it can be adapted to the harsh industrial field, data collection is accurately, processing speed is fast.

          3,Switch, contactor, rectifier, filter, buffer circuits and other electronic devices, all choose the reliable device, in the design choose the larger pressure, flow, coefficient of thermal protection.

          4,As far as possible in the structure design and manufacturing to reduce the distributed capacitance and inductance and raise resistance to radiation, induction and coupling interference ability.

          5, Parameters and program design strictness, system logic inputs and downtime, can better prevent system damage caused by the error operation and forced outage.

             Basic function:

           1,have the input voltage, output current dial indicator, working frequency, working voltage digital indicator.

            2,Current and frequency in setting within the scope of work infinitely variable control.

            3,System in the mixing state can be changed by adjusting the voltage working current.

           4,The system is equipped with continuous and time setting two kinds of working mode, under any mode it have clockwise stirring, anticlockwise stirring and automatic mixing the three kinds of mixing way, any stirring condition the mixing time, stop time, commutation stop time can be within the scope of the parameters set arbitrary.

          5,Fault indicator is divided into system outage, mixing stop failure and alarm failure three categories.

            A, System outage: including the cooling fan failure, the IPM module failure, rectifier fuse failure, main contactor of failure and the control of the power failure, etc.

           B, mixing stop failures: Including: a serious shortage of water, agitator winding serious overheating, the cooling fan stop.

           C, Alarm failure: including the shortage of water flow and water pressure, over-current and under-voltage unbalanced three phase current, etc.

            Our company is professional producing the 2-150 tons of various kinds of specifications with aluminum melting pot electromagnetic stirring device, is the non-ferrous metal industry electromagnetic products professional manufacturers and suppliers, the product series: furnace bottom inductive electromagnetic stirring device, lateral inductive electromagnetic stirring device, renewable aluminum industry with double room furnace electromagnetic blender, etc. Electromagnetic stirring technology application can be obtained as follows effect:

          1. Can make the melt alloy components uniform. General electromagnetic stirring device (no more than 20 minutes), can the whole furnace of various elements of the aluminium chemical composition of the relative deviation is less than 5%, can satisfy the almost all alloy to composition uniformity of the requirements.

          2. The mixing process not destroy the oxidation layer, can reduce the melt hydrogen absorbing and oxygen, ensure the quality of the melt, and reduce the loss (relative value) 20 to 25%.

         3. Can make the top and bottom of the melt temperature uniformity. General mixing ten minutes to the limit of the melt temperature can drop to less than 5 ℃. So can reduce melting temperature, can improve the melt bottom alloying melting degree, in lower melting again at the same time can reduce the degree of damage.

         4. In the process of aluminum ingots re-melting using electromagnetic stirring technology can shorten the time of smelting, improve work efficiency, reduce energy consumption, according to data provided by the already, can reduce energy consumption (improve efficiency) 20 to 30%.

         5. No pollution aluminum melting liquid. This has the important meaning for high purity aluminium and the iron control strict alloy.

        6. Can reduce the labor intensity, and improve working con.
