| 摘 要： | 利用软件CFX10.0对电炉炼钢氧枪在集束射流和普通射流两种状态下的特征进行了数值模拟.通过结果对比,论证了集束射流氧枪的优越性,并且在安阳一炼轧厂100t竖式电炉使用并对其使用效果进行了分析.结果表明,安阳一炼轧厂电炉使用集束氧枪后,吨钢电耗平均降低了30kW·h,吨钢氧耗和生产成本等方面都有明显的优势.冶炼周期略有增加,主要在于采用的原料中铁水比例增加,导致周期增加.当热装铁水比处于50%左右时,吨钢氧耗、吨钢电耗、冶炼周期和生产成本均变化不大,所以建议铁水比保持在50%.

| Abstract: | Software CFX 10.0 was used to simulate the characteristic of coherent jet oxygen lance and common oxygen lance.The advantage of coherent jet oxygen lance was proved by comparing the characteristic of the two lances.The coherent jet oxygen lance was used in the 100 t shaft EAF in Anyang Iron and Steel Co.Ltd.and the effect was analyzed.The results show that the electric consumption decreases by 30 kW?h and the advantage in oxygen consumption and production cost is obvious.Combustion cycle increases with the increase of hot metals proportion.The suggested hot metal ratio keeps about 50% because electric consumption,oxygen consumption,combustion cycle and production cost keep the similar level as hot metal ratio around 50%. |
