针对传统钢铁炉外精炼设备及其搅拌工艺能耗大、资源利用率低、环境负荷重等问题,提出利用重力势能驱动的旋流反应器用于金属的炉外精炼工艺,以达到降低环境负荷的目的.该反应器通过革新传统冶金反应器的构造,引入离心泵的设计原理,通过在漏斗形壁面上设置优良叶型的导流叶片,使沿导流叶片下流的钢液产生旋流,达到利用钢液本身的重力势能作为金属精炼搅拌动力的目的.利用水模型实验验证了这种新型冶金反应器的冶金特性,即对旋流生成与混合能力进行实验研究.结果表明,该反应器在工作中无需外加动力,产生的旋流能够提供金属冶炼所需的搅拌动力,较好的完成金属液的混合及冶炼过程;在已知的3种叶片形式中,前弯型叶片产生的旋流效果最佳.
In view of the problems of large energy consumption, low utilization rate of resources and heavy environmental load in traditional steel refining equipment outside the furnace and its stirring process, a swirling reactor driven by gravitational potential is proposed to be used in the metal outside refining process to reduce the environmental load The reactor through the reform of the traditional metallurgical reactor structure, the introduction of centrifugal pump design principles, through the funnel-shaped wall surface with good leaves-shaped guide vane, so that along the guide vane downstream flow swirling fluid to reach The gravity potential energy of molten steel itself is used as the power of the metal refining mixing power.The water model experiment is used to verify the metallurgical characteristics of the new metallurgical reactor that is the experimental study of cyclone generation and mixing ability.The results show that The work does not need external power, the generated swirl can provide the required power for the metal smelting, the better completion of the mixing and smelting of molten metal; in the three known blade forms, before the curved blade vortex Best effect.
