-
摘要: 通過(guò)現(xiàn)場(chǎng)試驗(yàn),分析了冷拔鋼管橫裂缺陷產(chǎn)生的原因,并制定了相應(yīng)的控制措施。實(shí)踐證明,采取的措施是有效的。Abstract: With experimental operation, causes responsible for transverse cracks of the cold-drawn steel tubes were investigated, and relevant countermeasures were taken to control the said defects.The operational result shows that the control measures taken are effective.
