The Use of a Magnetic Suspension for the Crucibleless Metal Melting

Abstract

Nowadays, the magnetic suspension is widely used in metallurgy for crucibleless melting of metals. We carry out the contactless suspension of metal under the inductor (a source of the high-frequency field), using the forces of interaction of the eddy currents, which are induced in the metal with a high-frequency magnetic field causing them. Besides, such a method of the suspension of metals allows to carry out simultaneously its heating and melting at the expense of the energy of the electromagnetic field of suspension

“…Also, rails are greatly affected by low temperatures. The creation of modern varieties of rail steel melting is aimed, among other things, to combat the effects of low temperatures in the track facilities [3].…”
