Kinetics about Refining Ultra Low Sulphur Steel by Using Slag Systems with BaO

摘要: 通过1 kg硅钼棒管式炉高温化学动力学实验,在实现钢中硫含量S ≤ 5×10^-6的前提下,对极低硫钢的精炼脱硫反应机理进行了研究,确定了极低硫钢精炼脱硫的反应级数、反应速率常数、反应的限制性环节和影响因素.

Abstract: Under the condition of realizingS ≤ 5×10^-6 in molten steel, the reaction mechanism of refining de-sulphurization for the steel with the lowest surphur content was investigated by high temperature chemical dynamic experiment in 1 kg Si-Mo bar pipe-furnace. The reaction progression, rate constant, bottle neck in reaction, and affecting factors were determined.
