How powerful magnets are made out of?
As countries officially released out incandescent roadmap to incandescent lamp production capacity in China will decline to 14, 2013.
200 million, energy-saving lamp output will reach 6 billion, for the current energy-saving lamps production 2 times.
Rare earth luminescent material as the basis of energy-saving lamps production must be raw materials, its market demand is bound to usher in explosive growth.
By 2013 China's energy-saving lamps with rare earth luminescent material market scale will reach 8000 ~ 10000 tons, the compound annual growth rate of 21%.
Rare earth permanent magnet as the most widely application field of the permanent magnet material, accounting for 60% of the total rare earth new materials consumption.
The third generation of permanent magnet, ndfeb is now the world's best permanent magnets, magnetic also is a kind of new rare earth materials consumption of rare earth the most.
High performance ndfeb permanent magnet materials applications mainly include: new energy, energy conservation and environmental protection fields, including wind power, energy-saving elevator, energy saving, environmental protection, such as air conditioning, new energy vehicles and traditional application field,
VCM and consumer electronics)
And so on.
The future as a hybrid car, energy conservation and environmental protection air conditioning demand unceasing enhancement, energy conservation, environmental protection and new energy will be the main application field for high performance ndfeb permanent magnet materials.
In hybrid cars, for example, the average each hybrid cars need 5 kg of high performance ndfeb permanent magnet materials, according to the estimate to 2014, the demand for high performance ndfeb hybrid car industry in China will reach 7800 tons.
How powerful magnets are made out of?
On hybrid and electric vehicles drive motors, Nd -
Sintered magnets is indispensable key components.
Compared with other magnets, magnet neodymium magnetic force strong, not only can achieve enough to drive the vehicle's power, but also can reduce the size of the to suitable for automotive use of the motor.
So, do you know how to make this kind of ndfeb strong magnet is out?
It will need to contain the necessary material of crushed into alloy particles, the particles together forming, and then sintered.
Then cut into required size to complete.
This process always feel like making a cake.
Of course, in the actual production of high quality ndfeb strong magnet is not so simple.
Not only uniform particles for 3 ~ 5 & mu;
M size, but also pay attention to the uniformity of shape, but also sintered when heating method, etc. , need to spend a lot of work to create.
'through a substantial accumulation of small technology, reached a practical level it is today' (
The technical personnel engaged in the development of neodymium magnets)
For example, the alloy pieces to 3 ~ 5 & mu;
M after the implementation of 'magnetic field in the molding process is one of them.
After the process is for crushing powder (
The orientation refers to the direction of magnetization of the micro powder is united for a fixed direction, the higher the orientation of sex, the residual magnetic flux density (
Magnetic field strength indicators)
The greater the.
Implement the process when powder filling into the mould first, strengthen the magnetic field orientation of micro powder, and then implement compression molding process.
The soak for molding will not collapse degree of soft body compression molding.
Because the pressure it will upset had a difficult time unified powder orientation.
If you want to achieve high orientation, also need to build magnetic field uniformity of the space inside the mold, it is also very important.
Because of the electromagnet configuration, and the mold size, shape, material can make uneven magnetic field, the deterioration in oriented, so you need to use magnetic field analysis method for fine-tuning, uniform magnetic field.
