FIELD: metallurgy.
SUBSTANCE: individual sectors of the housing are molten from steel with carbon content of 0.05-0.14% by a casting method as per gasified models. Sectors are connected to each other with lateral sides and welded along a junction line. A magnetic core is heat treated.
EFFECT: production of magnetic cores, the weight of which exceeds charging of a melting furnace by many times.
