为了以最低的生产成本来增加冶炼车间的产量和提高钢的质量,意大利 Venete钢公司于1988年对当时的设备进行了大修和完善。椭圆形底部出钢电炉(OBT)作为电炉炼钢具有先进技术特征的新原理得到了应用。这种电炉的炉形、电炉的炉盖、导电电极臂以及含氧燃料烧嘴、水冷氧枪和素质优良的一班操作人员的同心协力,达到了每小时75吨钢的生产率也即日产24炉钢。本文介绍了该电炉的技术细节及操作的结果。
In order to increase the output of the smelting plant and improve the quality of the steel at the lowest production cost, Italian steel company Venete overhauled and improved its equipment in 1988. The oval bottom tapping furnace (OBT) has been applied as a new principle of advanced technological characteristics for EAF. The stove-shaped furnace, furnace lid, conductive electrode arm and oxygen-containing fuel burner, water-cooled oxygen lance and a group of excellent operators work together to achieve the productivity of 75 tons of steel that is, Nissan 24 Furnace steel. This article describes the technical details of the electric furnace and the results of the operation.
