WO1986004838A1 - Method of casting metal into electromagnetic crystallizer - Google Patents

Abstract

A method of casting metal into an electromagnetic crystallizer consists in continuously feeding the metal melt (4) into the inductor (1) of the crystallizer under the influence of the electromagnetic field of which the ingot (6) is formed, its crystallization starting on a bottom plate (2) of the crystallizer at such a frequency of the current passing through the inductor (1) which ensures the balance between the hydrostatic pressure of the metal melt and the electrodynamic pressure of the electromagnetic field of the inductor (1) at a given cross-section of the ingot (6). Along with the crystallization of the melt (4) the ingot (6) is continuously drawn away from the inductor (1) by moving the bottom plate (2). When drawing the bottom plate (2) from inside the inductor (1) the current frequency is increased by a value which is proportional to the decrease of the electromagnetic pressure of the inductor field (1).

- 2 - a good effect is obtained in the first instance of an ingot. For example, an ingot is used and this will result in a closed circuit, that is, flowing through it, interacts with a pressure of 5 volts of the inductor, which relieves tension. The sectional shape of the resulting ingot is convenient for a particle. Therefore, the slice in the cross section may have any required configuration.

Therefore, the initial part of the merger, the formation of the company takes place in the industry in the past, but the area is smaller than the last. This part 10 is an ingot with a smaller cross-section of the mechanical part that separates the main part of the ingot, and it is lost to the reagent.

35 The metal alloy and the electrodynamic pressure of the electromagnet in the case of an industrial impulse are specified, but in spite of the resultant - C. - Shenigo electrical pressure for the field.

As a result, the process of pouring metal into an elec- tron-magnetic one results in a slight increase in size, which is only a little longer. This increases the productivity of labor, which leads to a decrease in the cost of electricity, since it is less than two times less, and it is much smaller.

The best embodiment of the invention of a method of pouring a metal into an electromagnetic magnetic process is as follows. 30 First, in the case of industrial metal I (fig.
