Abstract

긴밀하게 앞뒤로 배치되어 있으며, 단단히 고정ehl어 운전가능한 수평적-, 수직적-, 고리고 수vud적 이단 압연장치로 구성된 압연로 뒤에 배치된 압연장치 그룹내에서, 원형횡단면을 정해진 정확한 제품크기로 압연을 위한 작업방법.In the rolling machine group, which is arranged in close and front-to-back, rolling back consisting of horizontally, vertically, circular and several-duplex two-stage rolling machines, which are tightly fixed, can be rolled, the circular cross section is rolled to the correct product size. How to work.

이 작업방법에서는 14%내지 28%의 현저하게 더 강력한 흠제거시에 두개의 첫 압연장치(1,2)내에서 압연속도가 단지 더 작은 인장력만을 나타내는 것처럼 측정된다. 그리고 이 압연장치의 작동력이 마지막 압연장치(3)에서 1 내지 5%의 흠제거로 조절될때, 압연물의 횡단면이 압연장치와 앞서간 것 사이의 어떤 감소도 경험하지 못한 것처럼 제한치를 가지고 조정된다.In this method of operation, the rolling speed in the first two rolling mills (1, 2) is measured as showing only a smaller tensile force at 14% to 28% significantly stronger flaw removal. And when the operating force of this rolling apparatus is adjusted to 1 to 5% flaw removal in the last rolling apparatus 3, the cross section of the rolled product is adjusted with the limit as if no reduction was experienced between the rolling apparatus and the preceding one.
