Example Embodiment

[0021] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.

[0022] The invention provides an electric smelting furnace, such as figure 1 with 2 As shown, the electric smelting furnace includes a furnace body 1 and a plurality of electrodes 13. The top of the furnace body 1 is provided with an inlet 14 and the side wall of the furnace body 1 is provided with a liquid outlet 3 and a plurality of electrodes. A plurality of the electrode holes are arranged at the same height and above the liquid outlet 3, and a plurality of the electrodes 13 are arranged so as to be able to respectively pass through the plurality of electrode holes and extend obliquely downward so as to The furnace body 1 converges to form a high temperature digestion z...

Abstract

The invention relates to the technical field of miniature electric furnaces for casting material factory production, in particular to a smelting electric furnace. The smelting electric furnace comprises a furnace body (1) and a plurality of electrodes (13), wherein a feeding inlet (14) is formed in the top of the furnace body (1), a liquid outlet (3) and a plurality of electrode holes are formed in the side wall of the furnace body (1), the electrode holes are formed in the same height and located above the liquid outlet (3), the electrodes (13) are arranged to separately penetrate through theelectrode holes and obliquely extend downwards to form a high-temperature digestion area (15) in the furnace body (1), and the liquid outlet (3) is arranged to be higher than the high-temperature digestion area (15). According to the smelting electric furnace, the electrodes are arranged to extend obliquely downwards, so that the height difference between the electrode holes and the liquid outletis increased on the premise of maintaining the positional relationship between the high-temperature digestion area formed by the electrodes and the liquid outlet, the production process is optimized,and the operation safety is ensured.

Description

technical field [0001] The invention relates to the technical field of miniature electric furnaces in foundries, in particular to a smelting electric furnace. Background technique [0002] At present, micro electric furnaces in foundries often use electric arc furnaces, which mainly use the high temperature generated by electrode arcs to smelt ores and metals. The furnace body of the existing electric furnace usually adopts a square structure, and the structure of the molten pool in the furnace is also set to a square correspondingly. The furnace body includes a front side wall, a rear side wall, and a left side wall and a right The side wall, the electric furnace includes three electrodes (cylindrical structure) installed at the same height of the furnace body along the horizontal direction, which are named electrode A, electrode B and electrode C in turn, where electrode A and electrode B are inserted horizontally through the left and right side walls respectively The fur...
