韩国的POSCO(浦项钢公司)和RIST(工业科学技术研究所)正在与英国的Davy国际公司合作,共同开发双辊薄带连铸技术。已经建造了一台可生产宽350mm、卷重1t薄带材的中试机组,并在POSCO的浦项工厂交付使用。本文讨论了通过物理和数学模型测得的中试设备参数,评述了设备的运行和一般的操作实践,介绍了铸态和冷轧材料的产品质量评估原始结果,特别是关于薄带的表面和内在质量。
South Korea’s POSCO (Posco) and RIST (Institute of Industrial Science and Technology) are working with Davy International in the UK to jointly develop twin-roll strip casting. A pilot plant capable of producing 350mm wide rolls of 1t thin strip has been constructed and delivered at POSCO POSCO plant. This paper discusses the Pilot Plant parameters measured by physical and mathematical models, reviews equipment operation and general operational practices, and presents the original results of product quality assessments of as-cast and cold-rolled materials, particularly with regard to the surface of the ribbon and Inner quality.
