ELECTRODE FOR ELECTRIC ARC DC FURNACE OF CONTINUOUS ACTION Russian patent published in 2014 - IPC F27B3/24 H05B7/12 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy, in particular, to a system of cooling of a hearth electrode, made in the form of a bimetal cartridge, or an anode for DC arc furnaces of continuous action. The system comprises cooling facilities in the form of a header placed near the first edge of cooling facilities, having the end wall equipped with multiple channels, which connect the specified header with the first section of the gap arranged near the first steel section, the first tube for movement of the cooling liquid to the header, at the same time the area of the cross section of the header is at least 1.5 times more than the area of the cross section of the first tube, each of channels has a longitudinal axis, substantially perpendicular to the plane that is tangent to the appropriate output section, at the same time in the first section of the gap there are many jets of cooling liquid produced, substantially perpendicular to the main surface of the cavity arranged near the first steel section.

EFFECT: invention provides for increased efficiency of cooling action at a hearth electrode made in the form of a bimetal cartridge for provision of sufficient length of an electrode section, which remains in solid condition during furnace operation with availability of a very high electric load.
