电弧炉冶炼过程强化用氧特点分析

摘要

By analysis the melting process with EAF, the method of oxygen injection has been proposed in order to reduce electrical energy consumption. Based on the high temperature metallurgical physical chemistry reaction, the effect of elements oxidation in liquid steel on metallurgical bath was calculated. As can be found from the result, Once 10.1 m3 oxygen per ton steel was injected into the EAF bath, the energy of about 84.308 kW·h can be saved during the melting process of 45 steel with EAF.%通过电弧炉冶炼过程的分析，提出利用氧气助熔方式降低冶炼过程能耗。利用基本的高温冶金物理化学反应，结合实际冶炼过程，定量计算元素氧化烧损对熔池放热的影响程度。研究发现，在45#钢的电炉冶炼过程中，吨钢吹入10.1 m3氧气能够获得84.308 kW·h的能量补偿。
