鋼管微張力減徑增壁量的試驗與探討
Tests about and Approach to Steel Tube Wall Increase during Slight Stretch Reducing Process
-
摘要: 鋼管在減徑過程中,減徑量一定時,影響其增壁量的主要因素是鋼管的軋制溫度和張力系數(shù)等。就生產(chǎn)中出現(xiàn)的鋼管實際增壁量大于設(shè)計值的問題,采用不同的軋制工藝進行了試驗,探討了軋制工藝與鋼管增壁量之間的關(guān)系。Abstract: 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.
