随着工业技术的飞跃发展,对钢材的硫和磷等杂质的要求日益严格。由于在冶金过程中受不同的热力学和动力学条件的限制,使一些降低钢中杂质的反应过程难以在炼钢熔池内同时完善地进行,以至影响冶炼时间、效果及钢的质量。为适应炼钢技术向连续化、高效率和高质量的方向发展,国内外许多冶金工作者对铁水预处理技术进行了大量深入的研究并推出众多实用的工业性生产装置,使这项技术获得迅速的推广和应用。 With the rapid development of industrial technology, the requirements for impurities such as sulfur and phosphorus in steel are becoming more and more stringent. Due to the different thermodynamic and kinetic conditions in the metallurgical process, it is difficult for the reaction process of reducing the impurities in the steel to be carried out in the molten steel pool at the same time, so as to affect the smelting time, the effect and the quality of the steel. In order to adapt to the continuous, efficient and high-quality steelmaking technology development, many domestic and foreign metallurgical workers carried out a great deal of in-depth research on hot metal pretreatment technology and introduced many practical industrial production equipment to make this technology Prompt promotion and application.
