本文介绍了重钢铁水脱硫站的工艺设备及其特点,提供了冷热态试验和生产数据的统计资料以及炉外脱硫经济效益的初步估算。实践证明这项工程和技术是有效的,可靠的。为了减少喷溅、铁损和粘罐的程度,还应在脱硫剂和烟罩结构上研究改进。 This paper introduces the process equipment and its characteristics of the heavy steel hot metal desulphurization station, provides the statistical data of the hot and cold state test and production data and the preliminary estimation of the economic benefits of desulphurization outside the furnace. Practice has proved that this project and technology is effective and reliable. In order to reduce splashing, iron loss and viscosity of the tank, the desulfurization agent and hood structure should also be studied and improved.
