钢管微张力减径增壁量的试验与探讨

Tests about and Approach to Steel Tube Wall Increase during Slight Stretch Reducing Process

钢管在减径过程中,减径量一定时,影响其增壁量的主要因素是钢管的轧制温度和张力系数等。就生产中出现的钢管实际增壁量大于设计值的问题,采用不同的轧制工艺进行了试验,探讨了轧制工艺与钢管增壁量之间的关系。

During the process of reducing, in case of constant diameter reduction, the major elements responsible for tube wall increase are the rolling temperature and the stretch factor, etc. Pinpointing the problem that the actual wall increase amount is bigger than the designed value, tests involving different rolling processes are conducted, and the relationship between the rolling process and tube wall increase amount is studied.
