The invention is not limited to non-volatile non-ferrous metals and non-ferrous metals.

Most succesfully, the invention may be used for casting aluminum trowels and made of stainless steel.

PREFERRED EMBODIMENTS Known devices for continuous metal casting in magnetic field (& υ, Α, 233186). The appliance is suitable for the supply of a metal alloy to a separate dairy, a commercial, electrically-powered, and The cooling system of the ingot is made in the form of a decreasing part of the lower part of the cavity, a narrow response to the ingot eliminates the ingot. The refrigerant is discharged from the main camera along with the external wall of the partition to the merged one. The lower part of the territory of the Republic of Poland is located in the territory of the country, the limited internal internal industry and consumes the discharge of refrigerant is higher than the cost of evaporation.

However, with a significant thickness (more than 100 mm), a fusion of these thicknesses is not significant and should be neglected. In contrast to the short (up to 40 mm thick) area, such accidents are significant, as a result of which the ship is damaged.
