为了满足对矫直精度和矫直效率的更高要求，在七辊和两辊矫直机基础上，开发研制了φ80十辊圆钢矫直机组。十辊矫直机采用的恒压对辊压紧技术降低了对来料的要求；采用的液压马达预旋转结构显著提高了矫直速度；采用2－2－2－2－2的辊系布置提高了其矫直精度。整个矫直机组矫直速度最高可达2 m／s，圆钢矫直后直线度可达0.5 mm／m。对矫直机结构进行了强度、刚度有限元分析，保证设备的可靠性。%φ80 ten-rollers straightener had been developed and applied base on seven-rollers straightener and two-rollers straightener , to meet higher requirements of straightening precision and efficiency needs .Rollers compact technology of constant pressure reduces the requirement of raw material .Liquid motor pre-rotary struc-ture raises the straightener speed .Straightening speed is up to 2 m/s, the 2-2-2-2-2 rollers arrangement and raise the straighten precision .Straightness of round steel after straightened is up to 0.5mm/m.The strength and stiffness finite element analysis of structure has been done for the reliability .
