DESCRIPTION

Technology of manufacturing rapid-quenched magnetic powders (RQMP) is offered based on methods of centrifugal atomization or spraying of melt followed by rapid quenching on cooled shield. Centrifugal atomization, this technology, is providing the preparation of magnetic powders of wide variety of materials. BZMP (NdFeB powders) manufactured by new method are characterized by stable granulometry parameters, high-level of uniformity of alloying distribution in powder particles and fine-grained structure. This facilitates the forming the high coercivity condition of the material.

Common parameters:

Particle size: less than 400 mkm; Hci: 240 - 1300 kA/m; Br : 0.75 - 1.1 T; (BH)max: not less than 80 kJ/m3

Competitive advantages:

The centrifugal atomization for production of rapid-quenched magnetic powders (RQMP) is the only reliable alternative to Magnequench technology of melt spinning. Method of centrifugal atomization (CA) is featured by cheaper, simpler and more productive equipment than in spinning Magnequench (SM) technology.

  1. Productivity of centrifugal atomization (CA) 5-7 times as much as in spinning Magnequench (SM).
  2. Centrifugal atomization (CA) technology is free from processing problems inherent to spinning Magnequench (SM) technology
  3. Capability to control the thickness of flakes produced by centrifugal atomization (CA) method regardless of quenching rate, in comparison with spinning Magnequench (SM) methods, allows for obtaining the optimal quenched flakes in wide range of thickness (5 - 50 mkm) where nano-crystalline and amorphous powders can coexist
  4. Effective using the controlled crystallization annealing allows for obtaining powders of a wide combination of magnetic and other physical properties

Features:
  1. The smelting furnace gives higher yield.
  2. It starts up instantaneously thereby reducing the time to reach working temperature.
  3. The natural stirring helps in the uniform smelting.
  4. Smelting is cleaner.
  5. They can be installed even in the small place. Small furnace can provide high smelting rate. The small size with respect to melting rate results in the requirement of much less refractory than fuel-fired units.
  6. It is energy efficient, flexible operation.
Applications:

Refining of high purity magnet, metal and alloys; Electrodes for remelting; Casting of various engines; Foundries; Brazing; Iron and steel industry; Aluminum Industry etc.

Before purchasing induction smelting furnace you should bear following things in mind. Firstly you should be clear that for what purpose you are selecting the furnace. The size and width should depend on the area of its installation and the volume of work. For homogeneous melting there should be stirrer must you must ensure whether your furnace posses that feature or not. Induction heating process is a method in which the electrical conducting material is heated through by eddy currents induced by a varying electromagnetic field. The principle of the induction heating process is similar to that of a transformer.
