以酒钢板坯连铸中间包为研究对象,利用数学模拟方法,以挡墙与入口处、挡坝间的距离,挡墙和挡坝高度等为影响参数,对板坯连铸中间包流场进行优化设计,研究了中间包内钢液流场,对目前使用的中间包结构进行了优化,得出了有利于生产的设计数据。优化后酒钢二炼钢生产的铸坯在中板轧制时夹杂物缺陷下降了0.5%,提高了中间包的冶金功能。 Taking the tundish continuous casting tundish of Jiuquan Iron and Steel Co., Ltd. as the research object, using the mathematical simulation method, taking the distance between the retaining wall and the entrance and retaining dam, the retaining wall and the dam height as parameters, Optimize the design, study the flow field of molten steel in the tundish, optimize the tundish structure which is currently used, and get the design data that is beneficial to the production. After optimization, the steel slab produced by No.2 Steelmaking Plant reduced the inclusions defects by 0.5% during the middle plate rolling, which improved the metallurgical function of the tundish.
