紊流酸洗是一种能够有效降低带钢酸洗成本和提高效率的先进工艺与技术,在我国带钢酸洗行业正受到越来广泛的关注,但由于对该项新兴技术的原理尚缺乏深入认识,我国目前还只能靠模仿国外的紊流酸槽进行设计。为克服这种现状,采用现代计算流体力学(CFD)理论与方法,建立了紊流酸洗数值模拟技术,以某工程实际紊流酸洗系统为对象,以带钢表面紊流强度为评价指标,提出了在酸槽侧壁增加进酸口的优化设计方案。研究表明:该种新的进酸口位置及流量分配优化设计方案,对改善带钢表面紊流强度分布效果显著,并已成功应用于紊流酸洗工程,取得了良好的社会与经济效益。
Turbulent pickling is an advanced technology and technology that can effectively reduce strip pickling costs and improve efficiency. Strip pickling industry in China is receiving more and more attention. However, due to the lack of the principle of this emerging technology In-depth understanding of China’s current can only rely on imitation of foreign turbulent acid tank design. In order to overcome this situation, the numerical simulation technology of turbulent pickling was established by using the theory and method of modern computational fluid dynamics (CFD). Taking the actual turbulent pickling system of a project as an object and the turbulent intensity of the surface of the steel as the evaluation index , Proposed in the acid tank side to increase the acid inlet optimization design. The results show that this new design of inlet location and flow distribution optimization has significant effect on improving the distribution of turbulence intensity on strip surface and has been successfully applied to turbulent pickling project with good social and economic benefits.
