焊接鋼管管坯成型過程中鼓包的預(yù)防
A DISCUSSION ABOUT PREVENTION FROM BULGING IN BLANK FORMATION PROCESS OF WELDED STEEL TUBE
-
摘要: 簡要分析了帶鋼在成型為待焊開口管坯的變形過程中,其邊緣鼓包的形成機(jī)理。闡述了絕大部分鼓包都是材料、孔型、軋制線、設(shè)備、操作等因素綜合作用引起的,提出了預(yù)防鼓包的措施Abstract: The writer briefly analyses the mechanism of edge-bulging of the strip being formed into blanks to be welded and makes the point that in most cases the said bulging is developed due to a combined effect by such factors as material, groove, passing line, equjpment and operation.Some countermeasures against bulging are also proposed here.
