摘要
通过对钢管定径过程的理论分析,将定径机各架的辊径改为相等的辊径,最大张力达到2％,经生产实践证明,不会对钢管质量及定径过程产生不良影响。
Based on the theoretic analysis of sizing process, the same roll diameter for each stand is used instead of different diameters, and the max. stretch is up to 2%. Production practice proves that the measures taken above do no harm to pipe quality and sizing process.
