太钢第三炼钢厂连铸工程是冶金部重点技术改造项目,对改变传统生产工艺,缩短生产周期,赶超世界先进技术水平将起重要作用。在这样一个高大冶金厂房中,推广和采用了钢管混凝土柱,是太钢工程技术人员的一项大胆改革。钢管混凝土结构新颖合理,并具有许多优越性,这已为许多工程实践所证明。但是,由于管内混凝土的浇灌,长期以来仍存 The continuous casting project of the third steelmaking plant of TISCO is a key technological transformation project of the Ministry of Metallurgy, which will play an important role in changing the traditional production process, shortening the production cycle, and surpassing the world’s advanced technological level. In such a large metallurgical plant, the promotion and adoption of concrete-filled steel tube columns is a bold reform of TISCO engineers and technicians. The structure of concrete-filled steel tubes is novel and reasonable, and has many advantages. This has been proved by many engineering practices. However, due to the watering of the concrete in the pipe, it has remained for a long time
