不銹鋼熱軋(ya)中厚(hou)板工(gong)藝技術裝備主(zhu)要體現(xian)在爐卷軋(ya)機(ji)。

  爐卷(juan)軋(ya)(ya)機(ji)技(ji)術(shu)始于20世(shi)(shi)紀30年(nian)代，主要生產厚度3毫米(mi)以上的熱軋(ya)(ya)帶鋼。帶鋼進卷(juan)取(qu)爐的厚度為15～17毫米(mi)，爐內溫度950～1050℃，生產能力20萬～30萬噸／年(nian)。20世(shi)(shi)紀50-60年(nian)代其發(fa)(fa)展(zhan)較(jiao)快(kuai)，至20世(shi)(shi)紀70年(nian)代全(quan)世(shi)(shi)界已建爐卷(juan)軋(ya)(ya)機(ji)約(yue)34套(tao)，形成第一次(ci)發(fa)(fa)展(zhan)高(gao)潮(chao)。但由于爐卷(juan)軋(ya)(ya)機(ji)存在諸(zhu)多不足，20世(shi)(shi)紀80年(nian)代初，仍在生產的爐卷(juan)軋(ya)(ya)機(ji)已不超過(guo)20套(tao)。

  20世紀80年代中后期爐卷軋機復興，以生產不銹鋼(gang)為主的爐卷軋機因采用多項熱連軋機的控制技術得到長足發展，已成為不銹鋼領域的主力熱軋機。采用爐卷軋機軋制不銹鋼的主要原因為：（1）爐卷軋機前后設保溫卷取爐，適合不銹鋼等加工溫度范圍窄、難變形金屬的軋制；（2）專業化不銹帶鋼廠規模在25萬～50萬噸／年，用爐卷軋機生產能力適中，投資低，效益好；（3）現代化的爐卷軋機由于采用了厚度自動控制、板形控制、多次高壓水除鱗、快速換輥裝置等，從而保證了產品的尺寸精度、表面質量及板形等；（4）爐卷軋機在特種材料的軋制方面優勢明顯，可實現卷板品種優化。
