Referring to the domestic advanced rolling technology , rolling equipment, pass and auxiliary equipment choosing, specially, this ensure that the technology is reasonable and chosed equipment is advanced and there is space to produce highprofit rod . Bar is sale by sizing. All kinds of rolling mill can produce bar, such as opentrain mill, Bar to length delivery, barstyle, semicontinuous train and the continuous train. The pattern of continuous rolling bar in horizontal and vertical looper has the specility of the fewer accident, highly efficientand high output. In considering of the successfully producing, high lever automation, and stable quality controlling, the no twist continuous rolling is adopted in this classic production is θ26 bar. The workshop layout and pass paper and arrange pass paper is attached. Key words: workshop design。 bar production。 pass design。 high precision 目 錄 i 目 錄 摘 要 ...........................................................................................................................
