Abstract

The invention discloses a high-temperature smelting and reducing three-phase arc furnace, comprising a furnace lid lifting mechanism, an electrode, a furnace lid, a furnace hearth, a furnace body and a furnace body rotation speed reducer, wherein a cylindrical stand column is fixed on a foundation; a furnace lid lifting hydraulic cylinder is arranged inside the cylindrical stand column; a furnacelid rotating shaft is arranged on the cylindrical stand column; a furnace lid cradle platform is fixedly connected with the furnace rotating lid shaft; an electrode lifting stand column is welded on the furnace lid cradle platform; an electroconductive cross arm is arranged on the electrode lifting stand column; the electrode is clamped on the electroconductive cross arm; the furnace lid is arranged on the furnace lid cradle platform above the furnace body; a furnace body rotating bearing base is arranged on the foundation; and the furnace body rotation speed reducer is arranged on the foundation and is connected with the furnace body. The high-temperature smelting and reducing three-phase arc furnace disclosed by the invention has the advantages of simple structure, convenience in use, and deep furnace hearth with small diameter, more loose materials can be added into the furnace in one step, and the radiation range of heat generated by electric arcs is small, so that the temperatureinside the furnace is high; and the furnace body can rotate by 360 degrees, and thus all the materials in the furnace can be poured out due to the large rotation angle.

Description

Technical field [0001] The invention relates to a high-temperature smelting reduction three-phase electric arc furnace. Background technique [0002] The commonly used three-phase electric arc furnace is composed of a furnace body, a furnace tilting device, a furnace cover lifting and rotating mechanism, an electrode lifting device, and a hydraulic control department. The furnace body is composed of a furnace cover, a furnace door, a tapping trough and a furnace body. The furnace wall is built with alkaline refractory materials or acid refractory materials, and the ratio of the furnace depth to the furnace diameter D is less than 1. When tilting the furnace, the electrode lifting device, furnace cover, and furnace body are tilted together, and the tilting angle is less than 50 degrees. Because the furnace is wide and large, it is not easy to keep heat, and the tilt angle is small, it is difficult to repair the furnace and it is difficult to pour all the molten materials. Summar...
