Description

LF stove electrode accident handling device Technical Field The utility model relates to the technical field of electrode accident treatment, in particular to an LF furnace electrode accident treatment device. Background In modern steelmaking processes, LF furnaces (ladle finery) play a vital role. The LF furnace electrode is a key component in the steelmaking process, is mainly used for heating molten steel through electric arcs so as to adjust temperature, components and remove impurities, and plays a decisive role in improving the quality of steel. However, in the ladle furnace production process, the electrode is often damaged due to the fact that the electrode is subjected to complex thermal stress, and the electrode is broken when severe, so that the electrode needs to be lifted and replaced. The utility model patent CN202047084U discloses an LF furnace electrode hoisting system, which realizes effective hoisting when an electrode needs to be regulated or replaced, but when the electrode is operated, the electrode is likely to be broken due to thermal stress change, once the electrode is broken, a broken electrode can be inserted into molten steel, the temperature of the molten steel is extremely high, an operator is difficult to operate near the broken electrode, a special tool is not available at present, the broken electrode can be sleeved by using an alloy steel rope on a long rod, the process of bypassing the electrode by the alloy steel rope is extremely difficult, the electrode accident treatment time is long, the efficiency is low, the production rhythm is seriously influenced, and meanwhile, the operation process also has the risk of high-temperature scalding. Therefore, an electrode accident handling device of an LF furnace is needed, the operation that a steel rope bypasses an electrode in a short distance and with high difficulty is avoided, the electrode accident handling efficiency is improved, and the occurrence probability of safety accidents such as high-temperature scalds is reduced.
