直接铸带技术是以省略热轧或热粗轧为目的的薄板带生产方法。这种新的工艺技术具有巨大的经济效益和节能效果,是钢铁工业一项革新性的技术。本文较全面地叙述了自80年代以来世界各国对直接铸带技术的开发现状。并综合评述了固定模法、移动模法(双带法),以及双辊法等工艺技术的进展和发展趋势。固定模法将最早实用化,双带法已出现半工业性中试设备;双辊法是直接铸带技术研究的主流,是以直接连铸出稍经热轧或直接冷轧的薄带为目标的,技术难度较大,实现工业化还需要一定的时间。
Direct casting technology is to omit the hot-rolled or hot rough rolling for the purpose of the production method of sheet metal. This new technology has great economic and energy-saving effects and is an innovative technology in the steel industry. This article gives a comprehensive description of the status quo of direct casting technology in various countries in the world since the 1980s. The progress and development trend of process technology such as fixed mold method, moving mold method (double tape method) and double-roll method are reviewed. The fixed mold method will be the earliest practical, double-band method has emerged semi-industrial pilot equipment; double-roller method is the mainstream of direct casting technology, is a direct continuous casting of hot rolled or direct cold rolled strip Goal, technical difficulty, to achieve industrialization also need some time.
