言最近十幾年，熱連軋技術(shù)有了很大的進(jìn)步，在熱軋帶鋼軋機(jī)布置形式的發(fā)展方面，總結(jié)起來(lái)，主要有六種形式：典型的傳統(tǒng)熱帶鋼連軋機(jī)組，這種機(jī)組通常是 2 架可逆粗軋機(jī)，7 架精軋機(jī)，2 臺(tái)地下卷取機(jī)，年總產(chǎn)量 350~550 萬(wàn)噸，生產(chǎn)線的總長(zhǎng)度 400~500m，有一些新建的機(jī)組裝備了定寬壓力機(jī)(SP)。本著多品種，多規(guī)格的原則制定了產(chǎn)品大綱，其中包括汽車大梁鋼、船板鋼、管線鋼，汽車板用鋼等，并以其為出發(fā)點(diǎn)，盡量從工藝上使產(chǎn)品做到高質(zhì)量、高附加值。關(guān)鍵詞：多品種；兩架獨(dú)立的可逆粗軋機(jī)；CVC
