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, TEL: 86-730-8625951

and can achieve the goal of stirring at the same time. Speed and time can be adjusted at random. In 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.

Ⅴ. 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. TEL: 86-730-8625951

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
Others 1. Under the premise of non-changing the property of the products, two parties can negotiate and discuss to make a little change of the product at a small-scale. 2. For other matters and issues that not refer to, two parties (the user and supplier) can negotiate about them in other times
