项目摘要

Flat product manufacturers are under constant pressure to increase productivity, and simultaneously maintain high quality of continuously cast steel slabs because of stringent quality demands imposed by their customers. However, increasing productivity has detrimental effects on slab quality, and defects and rejections have a major impact on the producers bottom-line. Controlling fluid flows in continuous casting tundishes, and moulds is one of the key parameters to ensure cleaner steel and reduce defects. Physical and mathematical modelling is an absolutely essential tool to understand and optimize fluid flows in continuous casting. This project will deal with fluid flow optimization in the moulds, and that is the motivation of STELCO to collaborate with the University of Toronto. U of T will build an innovative state of the art water model facility to understand multiphase flow in moulds. In order to make the water model realistic, a 1/2 scale water model curved mould will be built, and exact geometries of the stopper rod and SEN will be replicated. Innovative manufacturing techniques including 3D printing and CNC machining will be used to reconstruct complex nozzle designs. The goal is to increase caster productivity and improve product quality. The project will identify solution strategies related to the following aspects (a) Optimized argon injection in moulds (b) Minimizing Sliver defects (c) Minimizing inclusion entrapment in the solidified shell due to curved mould (d) SEN design for casting narrow, wide and ultra wide slabs (e) SEN design for low speed casting versus high speed casting (f) Meniscus fluctuations and mould powder entrapment (g) Quantification of mould flow index through F value optimization (h) Minimization of SEN clogging through effective SEN design. The cost savings arising from improving the continuous casting process and enhancing steel quality is expected to exceed $3 million/year which is aligned with STELCO'S strategic vision and business goals, and will create immediate benefits. There will be an economic impact which translates to $15 Million within five years after completion of this project and will significantly boost the manufacturing sector of Ontario.
由于客户提出了严格的质量要求,板材产品制造商面临着提高生产率的持续压力,同时保持连铸钢板的高质量。然而,提高生产率会对板坯质量产生不利影响,而缺陷和废品对生产商的利润产生重大影响。控制连铸中间包和结晶器中的流体流动是确保钢材清洁和减少缺陷的关键参数之一。物理和数学建模是理解和优化连铸流体流动绝对重要的工具。该项目将处理模具中的流体流动优化,这也是 STELCO 与多伦多大学合作的动机。多伦多大学将建造一个创新的、最先进的水模型设施,以了解模具中的多相流。为了使水模型更加真实,将建造1/2比例的水模型曲面模具,并复制塞杆和SEN的精确几何形状。包括 3D 打印和 CNC 加工在内的创新制造技术将用于重建复杂的喷嘴设计。目标是提高连铸机生产率并提高产品质量。该项目将确定与以下方面相关的解决方案策略 (a) 优化模具中的氩气注入 (b) 最大限度地减少条子缺陷 (c) 最大限度地减少由于弯曲模具而在凝固壳中夹杂的夹杂物 (d) 针对窄、宽和窄铸件的 SEN 设计超宽板坯 (e) 低速铸造与高速铸造的 SEN 设计 (f) 弯液面波动和结晶器保护渣 (g) 通过 F 值优化量化结晶器流动指数 (h) 最小化通过有效的 SEN 设计消除 SEN 堵塞。改进连铸工艺和提高钢材质量所节省的成本预计将超过 300 万美元/年,这符合 STELCO 的战略愿景和业务目标,并将创造立竿见影的效益。该项目完成后五年内将产生 1500 万加元的经济影响,并将显着促进安大略省的制造业。
