辊模拉拔是一种先进的线材生产方法，60年代后期开始在生产中应用。从1964年在加拿大开始，到1982年全世界已有近150条包括有辊拔机在内的生产线。该技术在国内起步较晚，郑州金属制品研究院和北京科技大学等单位做了大量的设计和实验研究工作。目前，在冷拔螺纹钢筋、异型管、
Roller drawing is an advanced wire production method that began in the late 1960s in production. Starting in 1964 in Canada, by 1982 there were nearly 150 production lines in the world including roll drawing machines. The technology started late in China, Zhengzhou Metal Products Research Institute and Beijing University of Science and other units have done a lot of design and experimental research. At present, in the cold drawn rebar, special-shaped pipe,
