我厂从事炼钢生产已有二十多年的历史,由0.25t酸性电弧炉发展到现在的一台3t和一台5t碱性电弧炉。现年产钢水量约16000t。电弧炉结构为炉体开出式,电极升降为主立柱升降式,电极把持器采用水冷气动电极夹头,电极卡头曾采用铸钢、钢和焊接结构;铸铜和铸铜焊接结构。但在多年使用中常出现电极脱落,卡头和电极接触处起弧,卡头被击穿漏水,短网局部烧坏等事故,给正常生产带来了一定的困难。
Our factory engaged in steelmaking production has more than 20 years of history, from 0.25t acid electric arc furnace to the development of a 3t and a 5t alkaline electric arc furnace. The annual output of about 16,000 tons of molten steel. The structure of the electric arc furnace is out of the furnace body, the electrode is mainly up and down, the electrode holder is water cooled pneumatic electrode chuck, the electrode chuck is made of cast steel, steel and welded structure; the cast copper and cast copper welded structure. However, in many years of use, electrodes often fall off, the contact between the chuck and the electrode arcs, the chuck is punctured and leaks, and the short burned area partially burns and other accidents bring some difficulties to normal production.
