The aim of this thesis was to recover pure Fe powder from the magnetic filtered product.

The size of primary iron rich phases removed by electromagnetic filtration inverse ratios electromagnetic force and length to the power of 0.

The principle of the electromagnetic filtration is that under the action of EMF (electromagnetic force) the non-metallic inclusions with low electrical conductivity move in the direction opposite to that of the EMF.

The results show that the inclusions in aluminum base alloy melt can be captured when the melt flows through the electromagnetic field, which is called “electromagnetic filtration”, and the superficial percent of the inclusions trend to some certain value.

The application of magnetic filter can significantly reduce the above defects, so the properties of the f.

Attempts have been made to solve this problem by steering the cathode spots by a magnetic field, and by removing the droplets by a magnetic filter.

Magnetic filtered plasma deposition and implantation technique;

The effects of line magnetic filtering on the particles density and size in TiN and TiAlN films deposited by using arc ion plating have been examined by SEM.

The mechanism of the high gradient magnetic filter was analyzed theoretically,and the characteristics of the magnetic materials influenced by temperature were analyzed and tests.

A new model of plasma motion in rectangle 90o magnetic filter was founded and computed with electromagnetic in rectangle filter , and the stimulation result describe the distribution of plasma density well.
