It is shown that the uneven cooling of hot-rolled coiled material leads to inconsistent lengthwise characteristics of metal in a strip from one coil, welded joint zone included. One of the consequences of using this flat bar without controlled coil chilling (CCC) is an uneven relation of the mechanical properties of the main metal and the welded joint, which raises doubt about the possibility to eliminate this inconsistency by subsequent heat treatment. The study results show the need for optimizing the chilling of finished hot-rolled coiled material to reach a stable level of physical mechanical properties of items, where this material is used as the source material for producing cold-rolled products, pipes, metalware, etc. [ABSTRACT FROM AUTHOR] |
