目前我国极薄带材的研制和生产与国际先进水平相比,还有一定差距。美、苏等国已在试验室轧出厚度小于0.001毫米的极薄带材,其中莫斯科中央黑色冶金研究院设计的36辊试验轧机,在试验室的条件下曾轧出厚度为0.0005毫米(即5000埃)的79NiMn合金带。近几年来我国在这方面也取得了一定的进展。1974年上海有色金属研究所对北京冶金设计院于1968年设计,由上海彭浦机器厂制造的小型14辊轧机进行了改造,生产出了0.001至0.002×10至20毫米的极薄带材。北京钢铁研究总院于1975年用36辊轧机轧制出0.001×10
At present, there is still a certain gap between the development and production of ultra-thin strip in our country and the international advanced level. The United States, the Soviet Union and other countries have rolled out in the laboratory very thin strip thickness of less than 0.001 mm, of which the Moscow Central Black Metallurgy Institute designed 36-roll test mill, under laboratory conditions has rolled out a thickness of 0.0005 mm (ie 5000 Angstroms) 79NiMn alloy band. In recent years, our country has also made some progress in this regard. In 1974, the Shanghai Institute of Nonferrous Metals designed a small 14-roller mill designed by Beijing Metallurgical Design Institute in 1968 and manufactured at Shanghai Pengpu Machinery Factory to produce an extremely thin strip of 0.001 to 0.002 × 10 to 20 mm. Beijing Iron and Steel Research Institute in 1975 with 36 rolling mill rolling out 0.001 × 10
