1? commonly used in magnetic measuring instruments
Commonly used in magnetic measuring instruments are: the magnetic flux meter, tesla meter (also known as Gauss Meter), magnetic measurement instrument. Flux meter used to measure the magnetic induction flux, Tesla meter used to measure the surface magnetic field strength or air-gap magnetic field intensity, magnetic measurement instrument used to measure the integrated magnetic properties. All instruments should carefully read the instructions before using, according to the requirements specification preheating, preheating after the operation in accordance with the requirements of the specification.
2? NdFeB how to make it?
Sintered NdFeB Magnet is the application of a powder metallurgy process manufacturing iron-based permanent magnetic material. Main processes are: formulation, smelting, milling, molding orientation, sintering, machining, plating processing. Oxygen content of which is a measure of control over an important indicator of the level of technology. Our company production plant in the selection of a high-vacuum melting, sintering furnace, and advanced automatic control jet mill to ensure that the production process of basic oxygen-free operation, so that product performance and use of ground-breaking temperatures have increased.
3?magnet processing costs of the influencing factors?
Magnet processing costs mainly affected by the following factors: performance requirements, batch size, shape, size, tolerance dimensions. The higher performance requirements, cost higher, such as the N45 magnets prices far higher than the N35 price; quantities smaller the higher processing costs; shape the more complex the higher processing costs; tolerances more stringent, the higher processing costs.
4?on the rare-earth permanent magnetic materials
Rare-earth permanent magnetic material is samarium, neodymium rare earth and transition metal composition of mixed rare-earth permanent magnetic alloy, with pressed powder metallurgy sintering, by the magnetic field obtained after magnetizing a magnetic material.
Rare earth permanent magnet materials as a high-performance functional materials have been widely used in energy, transportation, machinery, medical care, 5, home appliances and other fields, has become the basis for a number of high-tech industries. NdFeB rare earth permanent magnetic material due to the high performance and low cost has become the fastest-growing industrialization of the highest degree of industry.
