国家“七五”重大科技攻关项目“同径双辊冷轧薄带坯连铸研究”是研究将钢水经过二个直径相同的水冷结晶辊直接连铸出1—5mm厚的薄带,直接供给冷轧作为坯料的新技术。它不但可以省去铸锭。锻造、热连轧等多道工序,节约大量的能源,减少基本建设投资,极大地降低生产成本,有巨大的潜在经济效益,而且还可以利用其快速凝固的特点开发生产一些常规工艺所难以生产的薄带材料。因此世界上各技术先进国家都投入大量的资金和力量,积极开发这一新技术。
National “Seventh Five-Year” major scientific and technological project “with the diameter of double-roll cold-rolled thin strip continuous casting research” is the study of molten steel through two identical diameter water-cooled crystal roll direct casting 1-5mm thick strip, direct supply Cold rolling as a new technology blank. It can not only save the ingot. Forging, hot rolling and other processes, save a lot of energy, reduce capital investment, greatly reduce production costs, there is a huge potential economic benefits, but also can use its rapid solidification of the characteristics of the development and production of some conventional process is difficult to produce Of the strip material. Therefore, all the countries with advanced technologies in the world have invested a lot of money and power to actively develop this new technology.
