Description

Руднотерд{ические печи относ тс  к печам с гор щей под слоем шихтовых материалов дугой, устойчивое горение которой  вл етс  важным фактором, в значительной мере вли ющим на ход технологического процесса.Ore-drums (furnaces) refer to furnaces with an arc burning under a layer of charge materials, the steady burning of which is an important factor that has a significant influence on the course of the technological process.

Повышение устойчивости горени  электрической дуги осуществл етс  путем ее активизации, осуществл емой воздействием магнитного пол  на зону дугового разр да.The increase in the stability of the electric arc is accomplished by activating it by the action of a magnetic field on the arc discharge zone.

С целью увеличени  этого воздействи  предлагаетс  в теле непрерывного электрода руднотермической печи вдоль оси электрода расположить участки токопровода по винтовой линии из материала, проводимость которого отлична от проводимости самого электрода.In order to increase this effect, it is proposed in the body of a continuous electrode of the ore-smelting furnace along the axis of the electrode to arrange sections of the conductor along a helix of a material whose conductivity differs from that of the electrode itself.

Наличие таких участков вызывает завихрение тока, протекающего по электроду, и, как следствие, увеличение воздействи  магнитного пол  на зону дугового разр да.The presence of such areas causes a turbulence of the current flowing through the electrode, and, as a result, an increase in the effect of the magnetic field on the arc discharge zone.

Получение в теле непрерывного электрода расположенных по винтовой линии участков из материала, проводимость которого отлична от проводимости самого электрода, может быть достигнуто, размещением ребер жесткости по винтовым лини м, путем применени  закрепленных внутри кожуха электрода хорошо провод щих (например, графитовых) пластин, или плоских карманов из сетки, заполненных плохо провод щим материалом, установки внутри электрода по его длине перегородки из хорошо провод щего материала, изогнутой по винтовой линии с осью, совпадающей с осью электрода и т. п.Obtaining in a continuous electrode body sections of a helix made of a material whose conductivity differs from that of the electrode itself can be achieved by placing stiffeners along the helical lines by using well-conducting (for example, graphite) plates fixed inside the electrode casing, or flat mesh pockets filled with poorly conductive material; installation inside the electrode along its length; partitions of well-conducting material curved along a helix with an axis that coincides with the axis of the electrode, etc.

Предмет изобретени Subject invention

Способ активизации электрических дуг непрерывных электродов руднотермических печей, отличающийс  тем, что, с целью увеличени  воздействи  магнитного пол  на зону дугового разр да, в теле электрода располагают вдоль оси электрода участки токопровода по винтовой линии из материала, проводимость которого отлична от проводимости самого электрода.A method for activating electric arcs of continuous electrodes of ore-smelting furnaces, characterized in that, in order to increase the effect of a magnetic field on the arc discharge zone, in the body of the electrode, along the axis of the electrode, conductor sections are placed along a helix of a material whose conductivity differs from that of the electrode itself.
