2.我国铝带坯连续铸轧技术的发展铝带坯连续铸轧技术在我国的发展大致经历了三个阶段。第一阶段自1964年1月至1967年初,1964年1月在哈尔滨东北轻合金加工厂成立了专门的机构,从事这一新工艺所需设备的研究。他们在“自立更生”精神鼓舞下,自行设计和制造了我国第一代双辊水平下注式连续铸轧机。1964年4月15开始工业试验,7月份铸轧成宽250毫米的板坯,9月份铸
2. China’s aluminum strip continuous casting and rolling technology development Aluminum strip continuous casting and rolling technology in our country’s development has gone through about three stages. The first phase from January 1964 to early 1967, January 1964 in Harbin Northeast Light Alloy Factory set up a special body, engaged in the equipment required for this new technology research. Inspired by the spirit of “independence and rejuvenation,” they designed and manufactured the first generation twin-roll horizontal continuous casting machine in China. April 15, 1964 Industrial test started, rolled into 250 mm wide slab in July, cast in September
