Electromagnetic pump @IDEA

               Electromagnetic pump is the use of magnetic field and in the conductive fluid interaction, make the   fluid by the electromagnetic force and pressure gradient, and a device to push the fluid motion. Mostly used for pumping liquid metal in the practical, so is also called the liquid metal electromagnetic pump. The role of electromagnetic pump is in the closed pipeline system to transmission of liquid metal, or other conductible liquid. In this sense, electromagnetic pump is familiar with rotating impeller drive equipment, the difference is the force generated in a different way. Drivers can use the right hand rule, when current flows through a conductor, will produce an induced magnetic field with metal solution produce induced current, induced current and magnetic field produce electromagnetic force, The force is the motive force of the molten metal movement, this force is not generated by mechanical components, and the metal solution not contact is the most important feature of electromagnetic pump.

               Electromagnetic pump has no mechanical moving parts, simple structure, good sealing, reliable operation, and don't need shaft seal, so in chemical, printing industry used to transport some toxic heavy metals, such as mercury, lead, etc. Used in nuclear power and nuclear fusion device transmit the molten nonferrous metals (sodium and potassium, sodium potassium alloy, lithium lead), more widely used in metallurgy transport molten nonferrous metal casting production. The flow rate can reach 13000 m/h, the pressure can reach 1.5 MPa, temperature is 1200 °C.

             Aluminium electromagnetic pump is based on the principle of linear motor. When the pump body work by special coil structure in the traveling wave magnetic field generated inside, magnetic field and the internal melting liquid interact to produce magnetic thrust, electromagnetic thrust high temperature melting furnace will take high speed to the circular liquid material well inner cavity, and on the material in high speed whirlpool well formed, whirlpool will be broken material involved, through the back into the melting pot bottom tube. Change the power supply voltage and current phase, can change the size of the electromagnetic thrust and direction.

           The application advantages of the electromagnetic pump

           1.Improve the metal recovery Electromagnetic pump system plays an important supporting role on improving the metal recovery of electromagnetic pump system, through the fast contact and rapid melting cycle, reduce sunk shorten melting process produce the scum of the recovery rate increase. Improve recycling the melting pot of the yield, improve the furnace cycle, and improve the production efficiency.

           2. Convenient to add alloy composition

           3.beneficial to uniform chemical composition

          4. Oxide residue reduceRely on the circulation of the powerful electromagnetic pump function and heat transfer ability, can reduce the surface temperature of molten pool, under the molten pool temperature can be controlled within 4 degrees. Through the material of high speed whirlpool flow in well, solid waste pile sinking fast to dissolve the bottom, reduce the contact with air time, shorten the melting time, the effective measures to greatly reduce the oxidation of slag formation.

         5. Save energyElectromagnetic pump system of the operating characteristics unique to reduce energy consumption, reflected in the following respects:

         Aluminum pool to the heat efficiency greatly improved, by electromagnetic pump system to create high speed large flow acceleration of the heat transfer, and produced a strong form vortex of sinking ability.

        The molten pool temperature gradient (poor) is less than 4 degrees.

        Through the door of the heat loss reduced, although have had to open the door into alloy.

        Through practical application of energy saving at least 10-20%

        6. Environmental characteristicsElectromagnetic pump systems rely on its unique design has caused many environmental advantage. Outside the furnace control characteristic is good, when the door closed allow many types of waste and other additives to aluminum molten pool. Alloy additive (including pure and composite alloy), melting and charging can in the furnace door close completed. This has very obvious advantage is the least furnace smoke from the flue open sending out. At the same time keep furnace temperature and open door into the furnace when the amount of air minimization.

        7. Shorten melting time improve production efficiencyRely on very high speed and capacity of flow ability, electromagnetic pump system can improve the rate of melting pot of fuses.

        8. Scrap is flexible and convenientRely on the eddy current electromagnetic pump produce all kinds of waste to melt.

        9. Help the uniformity of the melt temperatureBy electromagnetic pump system to produce a rapid cycle role, in the pool is 1 m high places will be less than 4 °C temperature.
