汽车用冷拔精密无缝钢管的生产

乌克兰国立管材科研所在研究了汽车用冷拔精密无缝钢管的使用要求和原苏联有关冷拔精密无缝钢管的技术标准的基础上，制定了冷拔精密无缝钢管的生产工艺，并介绍了该工艺的特点及保证几何尺寸精度的一些措施。已按此工艺生产出满足使用要求的冷拔精密无缝钢管。

PRODUCTION OF COLD-DRAWN PRECISION SEAMLESS STEEL TUBES FOR AUTOMOBILE PURPOSE

On the basis of a study concerning application requirements for motor-purpose cold-drawn precision seamless steel tubes and relevant technical criteria of the said product used in former USSR,the Ukrainian State Tubing institute set up the manufacturing process of the said cold-drawn precision tubes. Introduced in the paper are the characteristics of the process and some measures used to ensure the product geometric accuracy. With the said process,cold-drawn precision seamless steel tubes up to relevant application requirements have been produced.
