Danarc,达涅利电弧炉技术是指:带有喷吹氧和碳用的炉底风口的高阻抗技术,同时配以氧枪,以及供传统操作和后燃烧用的侧壁烧嘴。Danarc概念在能源的选择上提供了充分的灵活性。概念的基本原理是:具有高效的电能和可选能量的供给系统。从Danarc电炉在意大利的Ferriers Nord公司操作结果表明,作为电能的替代,喷入非常大量的氧和碳是可能的。 原料中金属回收率不受大量的吹氧量的影响。因为渣中的Fe氧化物含量是受喷入的C在渣中的平衡值控制的。 通过一个固定的或饱和的电抗器供电是有益的,因为甚至在高电压,低电流状况下操作也能得到稳定的电弧。所以,高阻抗操作会带来低的电极消耗,减少电损耗,及减小供电网络的干扰,也就是闪烁。饱和电抗器带来最好的结果。因为在这种情况下,附加的电抗器不断调整,保证一个合适和需要的量以使电流保持恒定。
Danarc, Danieli Electric arc furnace technology refers to the high-impedance technology with a furnace outlet for blowing oxygen and carbon, along with an oxygen lance, and side burners for conventional and post-combustion applications. The Danarc concept provides full flexibility in the choice of energy. The rationale for the concept is: a system of supply with efficient electrical energy and optional energy. Operating results from the Danarc furnace in Italy at Ferriers Nord show that it is possible to inject very large amounts of oxygen and carbon as an alternative to electricity. Metal recovery of raw materials from a large amount of oxygen blowing effect. Because the amount of Fe oxide in the slag is controlled by the equilibrium value of the injected C in the slag. It is beneficial to power from a fixed or saturated reactor because a stable arc can be obtained even with high voltage, low current conditions. Therefore, the high impedance operation will bring low electrode consumption, reduce electrical losses, and reduce the interference of the power supply network, that is, flashing. Saturated reactors bring the best results. Because in this case, the additional reactor is continuously adjusted to ensure a suitable and required amount to keep the current constant.
