Direct-current electric arc furnace

Abstract

The embodiment of the invention discloses a direct-current electric arc furnace which comprises an electric arc furnace body, an upper electrode and a lower electrode, and the upper electrode and the lower electrode are located in the electric arc furnace body. A dumping plate is arranged on one side of the electric arc furnace body, a power assembly is arranged on the other side of the electric arc furnace body, and a rotating assembly is arranged between the power assembly and the dumping plate. The power assembly comprises two symmetrically-distributed first electric push rods, the output ends of the first electric push rods are rotationally connected with the electric arc furnace body, sliding blocks are arranged at the ends, away from the electric arc furnace body, of the first electric push rods, and a moving assembly is arranged below the sliding blocks. The moving assembly comprises a fixing plate. According to the electric arc furnace, the moving assembly is arranged, when the electric arc furnace body needs a large overturning angle, the output shaft of a synchronous motor drives a fixedly-connected screw rod to rotate, the sliding blocks can gradually get close to the electric arc furnace body, and therefore the turnover angle of the electric arc furnace body is increased, and the limitation of adjustment of a traditional electric push rod is broken through.

Description

technical field [0001] The embodiments of the present application relate to the technical field of metallurgical equipment, in particular to a DC electric arc furnace. Background technique [0002] In the prior art, a DC electric arc furnace refers to an electric arc furnace that uses direct current as an energy source. Like an AC electric arc furnace, it uses the arc generated between the electrodes and the charge to generate heat to achieve the purpose of smelting. It can be used to smelt steel or alloys and non-ferrous metals. The smelting of metals, steel or alloys can melt the internal residues and requires the use of special slag melting equipment, and DC electric arc furnace is a kind of slag melting equipment. [0003] The existing electric arc furnace mainly uses the push rod to realize the turning of the electric arc furnace when it is in use. Due to the limited stroke of the push rod, the tilting angle is small, which limits the normal dumping and maintenance of t...
