Problems solved by technology
At the same time, the stability of the hand-made electrode is poor, so tripping and power failure often occur during the production process, resulting in long smelting time and large power consumption during the smelting process of high-titanium slag.
Moreover, due to the poor stability of the manual control electrode, the tripping and power failure of the titanium slag furnace often occurs during the production of high-titanium slag, which is also the main reason for the long smelting time and large power consumption in the high-titanium slag smelting process

The invention discloses a variable-frequency electric arc furnace. The variable-frequency electric arc furnace comprises self baking electrodes, a motor, a frequency converter, a power source and a master control device. The self baking electrodes are arranged in a furnace shell, and the motor controls the self baking electrodes to ascend and descend. The power source input end of the frequency converter is connected with the power source, and the power source output end of the frequency converter is connected with the motor. The master control device is connected with the frequency converter, and the frequency converter outputs alternating currents subjected to frequency conversion processing according to frequency conversion control commands sent by the master control device. According to the variable-frequency electric arc furnace, the electrodes are controlled through a motor frequency conversion technology, so that the electrodes are stable in ascending, stopping and descending operation, the product quality is improved, and the power consumption is reduced. In addition, the smelting time of high-titanium slag can be shortened, and the unit product power consumption is reduced, so that the production cost is reduced, and the product quality and enterprise comprehensive competitiveness are improved.
Description
Technical field [0001] The invention relates to the technical field of industrial electric furnaces, in particular to a frequency conversion electric arc furnace. Background technique [0002] As a rare metal, titanium has become an indispensable important raw material and new structural material in the development of the national economy. Titanium is one of the most widely distributed and abundant elements in the earth’s crust, accounting for 0.61% of the weight of the earth’s crust and ranking 9th; while titanium resources are ranked 4th after iron, aluminum, and magnesium. An important raw material for titanium slag, artificial rutile, titanium white, sponge titanium, titanium metal, titanium material, and electrode coating. Metal titanium is silver-white, with high melting point, light specific gravity, high mechanical strength, abrasion resistance, good plasticity of linear titanium, not easy to oxidize, and strong reducibility; the oxide of titanium-titanium dioxide (titan...
