其新技术主要是:①新型水冷超声氧枪,可实现高脱碳和强湍流,从而提高电炉的脱碳效率并减少电耗,使氧的总利用率提高60％;②采用完全水冷的炉顶和铜—钢组合的水冷炉壁,冷却快,其使用寿命可达6000炉次;③废钢及直接还原铁实行连续预热和连续装料,④整个工艺过程自动化,包括从废钢场、电弧炉直至二次冶炼。通过一台主计算机对炼钢车间进行全面管理,可记录各种操作数据,并为
The new technology is mainly: ① new water-cooled ultrasonic oxygen lance, which can achieve high decarburization and strong turbulence, thereby enhancing the decarburization efficiency and reduce power consumption, so that the total oxygen utilization increased by 60%; ② completely water-cooled furnace Top and copper - steel combination of water-cooled furnace wall, fast cooling, the service life of up to 6000 furnaces; ③ scrap and DRI continuous preheating and continuous charging, the entire process automation, including from the steel scrap field, the arc Furnace until the second smelting. Through a host computer to fully manage the steelmaking plant, can record a variety of operational data, and
