现代化带钢生产采用四辊二个到六个机架的连续轧机、四辊单机架可逆式轧机和各种类型的多辊轧机。连续式机是用作大规模生产比较单一的品种;四辊单机架可逆式轧轧机用于生产规模较小,或轧制特殊钢及其它产品;多辊轧机则应用于特殊钢、极薄带及钢箔的生产。在资本主义国家中共建立了100多台连续式冷轧宽带轧机,轧辊辊身长度达900毫米;甚至更大,美国约占66台。这些轧机的年生产能力大致估算已超过5400万吨,其中美国为3500万吨,约占65％;在欧洲国家中有25台连续式冷轧宽带轧机,年生产能力为1300万吨左右,约占25％;其它资本主义国家有16台,年生产能力为600万吨左右,约占10％;其中日本有10台轧机。可逆式冷轧宽带轧机大约建立了100多台,它们的年生产能力为900万吨左右。多辊式冷轧宽带轧机建立得比较少(和可逆式相比),它们的生产能
Modern strip production uses four-roll two to six-stand continuous mills, four-roll single-stand reversing mills and various types of multi-roll mills. Continuous machine is used for large-scale production of relatively single species; four-roll single-stand reversing mill for the production of smaller, or rolling special steel and other products; multi-roll mills are used in special steel, And the production of steel foil. In the capitalist countries, the CCP has established more than 100 continuous cold-rolled broadband rolling mills, with rolls with a length of 900 mm or more and the United States accounting for about 66. The annual production capacity of these rolling mills has been estimated at more than 54 million tons, of which 35 million tons in the United States, accounting for about 65%; in Europe, there are 25 continuous cold rolling mill with an annual production capacity of about 13 million tons, about Accounting for 25%; other capitalist countries have 16, the annual production capacity of 6 million tons, accounting for about 10%; of which Japan has 10 rolling mills. Reversible cold-rolled broadband mills about established more than 100 units, their annual production capacity of 9 million tons. Multi-roll cold-rolling broadband mills are relatively small (compared to reversible ones) and their production capacity
