【導(dǎo)讀】從精軋最后一架軋機(jī)出來的熱鋼帶通過層流冷卻至設(shè)。卷及縱切鋼帶產(chǎn)品。橋梁、建筑、機(jī)械、壓力容器等制造行業(yè)。越廣泛的應(yīng)用并在市場上具有越來越強(qiáng)的競爭力。各種不同用途，對鋼板的材質(zhì)性能、表面質(zhì)量。抗拉強(qiáng)度、屈服點(diǎn)、伸長率及沖擊吸收功是表示熱軋鋼。板力學(xué)性能的主要指標(biāo)。其大小表示鋼材抵抗各種作用的能。設(shè)計(jì)時(shí)選材和進(jìn)行強(qiáng)度計(jì)算的主要依據(jù)。伸試驗(yàn)及沖擊試驗(yàn)等。降低而試樣仍能繼續(xù)伸長（變形）時(shí)的應(yīng)力。度愈低，產(chǎn)生永久變形所需的力愈小，即愈容易成形加工。標(biāo)距長度的百分比。伸長率的比數(shù)愈大，則表示材料在受力。小，表示金屬材料對沖擊負(fù)荷的抵抗能力。不良而出現(xiàn)缺陷。然而材料的屈服點(diǎn)小于140Mpa時(shí)，又可能。加工或沖壓加工的鋼板，通常要求具有比較低的屈服強(qiáng)度值，要求其具有一定足夠高的沖擊韌性-沖擊功值。熱連軋鋼板產(chǎn)品包括帶（卷）及由其剪切而成的鋼板。整線重卷、平整的平整卷。
