目前，近终形连铸工艺正在蓬勃地发展起来，这不能不对钢铁工业的结构产生影响。新的生产扁材的小钢厂已经成为传统大型钢铁企业的竞争对手。本文拟从技术和经济的角度作一些探讨。传统高效率连铸机的浇铸和轧制阶段的生产成本与ＣＳＰ和ＣＰＲ工艺的成本差不多，如果采用双辊带钢连铸法，生产成本更高些。新工艺具有明显的优点：投资少，流程短，计划管理和运输费用低，但在品种和规格方面有明显的限制。因此，小钢厂在扁材生产上占有经济优势 At present, nearly continuous casting process is being developed vigorously, which can not but have an impact on the structure of the steel industry. The new small mills that produce flat bars have become competitors to the traditional large-scale steel companies. This article intends to make some discussions from a technical and economic point of view. The production costs of the traditional high-efficiency caster at the casting and rolling stages are similar to those of the CSP and CPR processes, which are more expensive to produce with the two-roll strip continuous casting method. The new process has the obvious advantages of less investment, shorter processes, lower program management and shipping costs, but with significant limitations in terms of variety and specifications. As a result, small steel mills have economic advantages in producing flat products
