江苏苏北地区最大的30吨炼钢电弧炉于6月6日凌晨在南通钢厂一次试产成功,并顺利出钢。这项工程由江苏省冶金设计院设计。总规模为年产30万吨钢,一次规划,分期建设。工程设计采用了新工艺、新技术。电弧炉采用密封大烟罩除尘,减轻噪声,改善炉前工人操作环境;采用高位料仓自动称量皮带输送、炉顶四孔加料装置,可使用直接还原铁连续装料;电炉预留了废钢预热,偏心炉底出钢的条件,在设计中还考虑了钢包喷粉和炉外精炼装置的位置;小方坯连铸机选用刚性引锭杆,用钢包移送台代替钢包迥转台。
Jiangsu’s northern region’s largest 30-ton steelmaking electric arc furnace in the early morning of June 6 in Nantong Steel a successful pilot production and smooth tapping. This project is designed by Jiangsu Provincial Metallurgical Design Institute. The total scale of an annual output of 300,000 tons of steel, a planning, construction by stages. Engineering design using new technology, new technology. The electric arc furnace uses sealed smoke hood to reduce the noise and improve the working environment of the furnace. The conveyor belt is automatically weighed by a high silo, and the top four-hole feeding device can be continuously charged with direct reduction iron. The electric furnace is reserved for scrap Preheating, eccentric hearth tapping conditions, also considered in the design of ladle dusting and furnace refining device location; billet continuous casting machine rigid dummy bar, ladle transfer station instead of ladle turntable.
