齐齐哈尔钢厂将从法国引进的一台老式电弧炉改造成具有八十年代水平的偏心底出钢EBT电弧炉获得成功。于1992年11月6日在哈尔滨通过黑龙江省冶金厅组织的技术鉴定。齐钢1990年从法国引进的二手HP45t电弧炉,采用低位出钢槽出钢,总体设计为70年代水平,与目前国际先进的EBT电弧炉相比,这种老式电弧炉在设计和操作上都存在一些缺点,钢水二次氧化严重、出钢温降大,冶炼时间长,耐火材料及电极消耗高,炉体寿命低,齐钢在原电弧炉的基础上,在不破坏原电弧炉基本结构的原则下,设计出具有自己特点的电弧炉。该装置实现了氢气幕保护封闭无渣出钢,平面旋转档板式水口开闭,钢水电子称自动计量和显示,与
Qiqihar Steel succeeded in transforming an old electric arc furnace imported from France into an EBT electric arc furnace with an eccentric bottom in the 1980’s. On November 6, 1992 in Harbin through the Heilongjiang Provincial Metallurgical Office of the technical appraisal. Qi steel introduced from France in 1990 second-hand HP45t electric arc furnace, the use of low tapping steel tapping, the overall design for the 70’s level, compared with the current international advanced EBT EAF, the design and operation of the old electric arc furnace There are some shortcomings, severe secondary oxidation of molten steel, tapping temperature drop, smelting a long time, high refractory and electrode consumption, furnace life is low, the steel in the original arc furnace, based on the original structure of the original arc furnace without damage In principle, the design of electric arc furnace with its own characteristics. The device realizes the hydrogen curtain closed closed without slag tapping, the flat rotating baffle nozzle opening and closing, the molten steel electron weighing automatic weighing and the display, and
