热轧带钢无头轧制技术诞生于常规热轧宽带钢轧机,之后有一批薄板坯连铸连轧产线采用半无头轧制技术,但由于轧制机理及其他方面的局限性,不能认为是一个理想的工艺产线。近几年国外两套以原有ISP(在线带钢工艺)型式的薄板坯连铸连轧产线为原型进行了无头轧制改造,特别是意大利阿维迪无头轧制产线的构成及特点,揭示了无头轧制技术发展的某些特征。国内薄板坯连铸连轧最多的是CSP产线,以国内某套一代半的CSP机组迁建项目为例,对改造成无头轧制产线进行技术分析,提出改造的设想方案及改造的效果预期。未来热轧带钢无头轧制技术的发展前景取决于在技术性、经济性及适用性方面的竞争力。
The hot strip rolling technology was born in the conventional hot rolling wide strip mill, followed by a number of thin slab casting and rolling production line with semi-endless rolling technology, but due to the rolling mechanism and other limitations, can not Think it is an ideal craft production line. In recent years, two sets of foreign countries to the original ISP (online strip technology) type of thin slab continuous casting and rolling production line as the prototype of the endless rolling transformation, especially in Italy Avid endless rolling production line And features, revealing some of the characteristics of the development of endless rolling technology. CSP production line is the largest in China for the production of thin slab continuous casting and rolling. Taking the relocation project of a certain generation of CSP units in China as an example, the technical analysis of the transformation into headless rolling production line is put forward, and the tentative plan and reformation of transformation are put forward The effect is expected. The future of hot rolled strip headless rolling technology depends on the technical, economic and applicability of the competitiveness.
