    Bottom-mounted Permanent Magnet Stirrer

    YC-1180S

    Technical Specification

    I. Operating principle

    Bottom-mounted permanent magnetic stirrer is a permanent magnetic sensor that uses special

    combination. It is equivalent to a motor that with big air gap and use permanent magnet magnetic

    field. The magnetic sensor just like the stator of the motor, and the non-ferrous metals liquid is

    equal to the rotor of the motor. Through the way of mechanical rotary, the magnetic filed and

    non-ferrous metals in the molten pool will interact, then will produce induced electromotive force

    and induced current. The induced current will effect with the magnetic filed, then make the

    electromagnetic force which would push the liquid to move directionally that plays a role of stirring.

    It consists of the main drive system, rack assembly, sensor assembly, lifting system assembly,

    cooling system, walking mechanism control system.

    II. Features of the permanent magnetic stirrer:

    1. Using high remanence, high coercive force intense magnetic Ru-Fe-B make up a special sensor,

    to non-contact mix the smelting metal via mechanical transmission and advanced control system.

    2. The magnetic field can make the liquid aluminum rotating in 0-15r/min, washing out, soaking

    and smelting the cold slag or aluminum scrap , to reduce the aluminum scrap burning loss, improve

    the melting rate and lower the energy consumption; in general it can reduce about 50% relative

    burning loss according to the conditions of the materials.

    3. In the situation of alloy configuration, it can accelerate the melting of the alloy, homogenize the

    alloy composition and refine the grains, improve the product quality; after 15 minutes stirring, we

    make the samples in many places and test each sample composition, which will meet the need that

    the relative deviation value of the alloy is in line with the national related standard.

    4. Eliminating the upper and lower temperature difference, improve the heat transfer efficiency

    from furnace chamber to the molten pool efficiently, lowering the combustion chamber temperature

    greatly. The temperature of the melt will differ in 0-5 after 15 minutes stirring.

    5. When setting the actual stir intensity, should be better to see the ripple of the rotation form the

    surface but not damage the oxide layer, which could further reduce the burning loss and oxidation,

    addition, it has good effect of liquid vortex.

    III. Energy consumption of the stirrer:

    The stirrer takes permanent magnet as sensor, the power consumptive components are only the

    mixing drive motor, blower, moving motor and lifting motor. The driving motor is frequency

    controlled. When in operation, the practice power of the mixing motor is 30%-50% of the rated

    power. Other motors work in intermittency, so the power consumption is much less.

    IV. Main Technical Parameters of the Stirrer

    No. Item Parameters Remark

    1 Liquid aluminum depth 700 2 Suitable environment temperature 50 It can be adjusted

    3 Magnetic induction density 600GS (250mm away

    from the cover)

    4 Rotation speed of the center aluminum liquid

    0-15r/min (can be adjusted)

    When the temperature of the aluminum liquid is 740 ,depth of the aluminum 650mm

    5 lifetime of the permanent magnet 10 years

    . Control system 1. The moving, lifting, mixing of the permanent magnet stirrer and the power-on of the fan are all

    controlled by the operation board of the electric control box.

    2. The frequency converter has the function of malfunction/fault diagnose, alarm and display. It also

    can diagnose, alarm and display the over-current, over-pressure, low-pressure, over-temperature,

    semiconductor, communication and discharge etc. elements, and has the protection function of

    broken circuit, short circuit, over load and open-phase.

    3. Alarm and fault signals will be displayed on the controller of the frequency converter and the

    operation board of the electric control cabinet.

    4. There is a temperature sensor in the mixing machine, when the temperature of the mixing

    machine is beyond 50, the equipment will alarm automatically, then it would stop working and

    back to inspect and fix parking position. The temperature can be set by man.

    5. The mounting place of the permanent magnet mixing machine: bottom of the furnace

    6. The permanent magnet mixer has the function of move and mixing

    7. All the operations are easy, and it has the function of interlock
