摘要： A plasma torch includes two tubular coaxial electrodes, at least one of which is axially movable between an operating position in which the movable electrode is spaced from the other electrode and an initiating position in which the movable electrode is in contact with the other electrode, thus establishing an electric short circuit so as to generate an electric arc upon rupture of the electric short circuit hen the mobile electrode is brought back to its operating position. Each electrode is contained in a support provided with a cooling circuit, through which a cooling fluid circulates. The cooling circuit associated with the movable electrode is provided with a seal which permits the electrode to be moved without creating any leaks in the cooling circuit.

摘要： This invention relates to a plasma torch and a first and second electrode for use in a plasma torch. Each electrode includes a tubular intermediate part which is intended to come into contact with the arc feet and a pair of end parts which are intended to facilitate connection of the electrode to the other parts of the torch. Each electrode is disposed within an enclosed fluid circulation chamber within which a cooling fluid circulates. The intermediate and end parts of each electrode are at least ten millimeters thick. The individual parts of each electrode are connected together by a moisture-impervious, disassemblable, mechanical assembly which prevents the cooling fluid from coming in contact with the interior of the electrodes.

摘要： Method for heating the reducing gas of a blast furnace by means of a plasma generator. The reducing gas flows through a pipe into which issues the nozzle of the plasma generator. The pipe leads towards a tuyere of injection into the blast furnace, and the axis of said nozzle converging towards that of the pipe. The method is characterized in that the acute angle A between the axis of the nozzle and the axis of the pipe is at the most equal to 50.degree., in that the distance 1 separating the point of intersection of the axis of the pipe with the axis of the nozzle from the center of the outlet orifice of the nozzle is at the most equal toD/2sinA,D being the inner diameter of the reducing gas inlet pipe, and in that the ratioD/d,in which d is the inner diameter of the outlet orifice of the nozzle is at least equal to 1.5. The object of the method is to eliminate wear of the reducing gas pipe by means of the jet of plasma.
