一、前言 早在一百三十多年前,英国人(Sir Henry Bessemer)贝塞麦在他的专利中就提到了一种铸造、结晶和轧制过程同时在一对轧辊上完成的所谓“无锭轧制”模型。按照这种工艺模型,美国和苏联曾在一段较长的时期内进行过较大规模的试验。限于当时的技术发展条件,最终未能实施生产。但一百多年来,对此项技术的研究工作从未间断过。先后开发了双辊法、单辊法、双带法、外环内辊法、喷射沉积法等一系列直接铸造薄带坯的方法。大大丰富了贝塞
I. INTRODUCTION As early as over one hundred and thirty years ago, Sir Henry Bessemer of the British People’s Republic of Serbia referred in his patent to a process called casting, crystallizing and rolling which is done simultaneously on a pair of rolls. Ingot rolling "model. According to this process model, the United States and the Soviet Union conducted large-scale trials over a long period of time. Limited to the conditions for the development of technology at the time, eventually failed to implement the production. However, over a hundred years, the research on this technology has never ceased. Has developed a double roll method, single roll method, double belt method, outer ring inner roll method, spray deposition and a series of direct casting thin strip method. Greatly enriched Besse
