Submerged arc furnace electrode in-furnace depth automatic measuring system and method thereof

Abstract

The invention discloses a submerged arc furnace electrode in-furnace depth automatic measuring system. The system comprises a voltage-release meter counter installed on a submerged arc furnace electrode holder, a temperature measuring device installed on the furnace wall of a submerged arc furnace, and a voltage acquisition module for acquiring the voltage of the high-voltage side of the submerged arc furnace. A submerged arc furnace electrode in-furnace depth automatic measurement method comprises the following steps: S1, continuously collecting temperatures of 45 thermocouple point locations, and collecting current data of high-voltage side voltage, low-voltage compensation current, transformer bushing current, phase transformer gear and active power; by setting the temperature field and combining the low-voltage compensation current, the transformer gear signal, the electrode voltage release parameter and the transformer bushing current, operation errors caused by different teams and groups are reduced, the normal production time is prolonged, the labor intensity of workers and errors caused by manual operation are reduced, the safety is improved, and the production efficiency is improved. And transformation from raw material production to digitization, networking and intelligentization can be realized, and the accuracy of digitization production is improved.
