Description

technical field [0001] The invention relates to a melting furnace, in particular to a high-temperature melting furnace used for copper material processing. Background technique [0002] In the current industrial production, most of the melting furnaces used are electric arc furnaces. Electric arc furnaces use the high temperature generated by electrode arcs to smelt ores and metals. During the smelting process, the electrodes used to generate arcs are in the middle of the materials. At present, electric arc furnaces mostly use AC arc, but because AC itself is a sine wave, it crosses zero point 100 times per second, the arc is extinguished near zero point, and then re-ignites in the opposite direction, so the stability of AC arc is poor, and it does not occur during the electric melting process. Unstable, the size and direction also change instantaneously. Therefore, the energy consumption is high, and it is easy to generate smoke, dust and arc light, and the noise is large, ...

At present, electric arc furnaces mostly use AC arc, but because AC itself is a sine wave, it crosses zero point 100 times per second, the arc is extinguished near zero point, and then re-ignites in the opposite direction, so the stability of AC arc is poor, and it does not occur during the electric melting process. Unstable, the size and direction also change instantaneously. Therefore, the energy consumption is high, and it is easy to generate smoke, dust and arc light, and the noise is large, which has a great impact on the working environment and the surrounding environment, and has a great impact on people's health. damage, causing fatal damage to surrounding crops, and environmental governance is also quite difficult

At the same time, since the material to be smelted is surrounded by the electrodes that generate the arc, part of the high temperature generated in the furnace is emitted through the furnace wall, resulting in waste of heat energy and low efficiency of heat energy utilization. Causes a splash accident, has a certain degree of danger
