Abstract
  In steel production plants, such as those manufacturing sheets, pipes, and round bars, raw materials are annealed in preheating furnaces at approximately 1200 oC before undergoing hot deformation process. Substantial oxidation and loss of raw steel materials occur in preheating furnaces, resulting in ...  Read More

Abstract
  Fin-pass rolls are the latest series of rolls in electric resistance welding (ERW) pipe production lines that form the sheets to tubular shape and adjust the edges of the sheet for welding. The rolls (made of AISI 8622 steel) lose their proper function after about 10 years of operation due to severe ...  Read More
