 阿塞(sai)洛(luo)公司及其五個控(kong)股的不(bu)銹(xiu)鋼子公司的生產工藝(yi)流程舉(ju)例如下：

上述幾個工藝流程的特點可(ke)以概括為：

 ①. 1999年3月在伊斯貝格廠建成世界最新的緊湊式連續冷軋退火酸洗生產線，年產能力25~27萬噸，產品為（0.8)1.0~4mmx700~1600mm冷軋不銹鋼帶。該生產線只需一步就可將熱軋不銹鋼卷加工成冷軋不銹鋼帶，從而縮短了工序，降低了成本。

 ②. ALZ公司采用三步法(fa)冶煉工藝(yi)，連(lian)鑄的板(ban)坯經熱連(lian)軋（外廠(chang)加工）后(hou)在(zai)本廠(chang)2套冷軋機上冷軋，然后(hou)退火、酸洗(xi)、精整。

 ③. ALZ公司擁有目前世(shi)界(jie)上惟一能生(sheng)產(chan)2000mm寬、厚度可達(da)到8mm冷(leng)軋(ya)不銹(xiu)鋼(gang)卷的(de)(de)生(sheng)產(chan)線，也(ye)是世(shi)界(jie)上少數幾家可生(sheng)產(chan)寬度達(da)2000mm熱軋(ya)不銹(xiu)鋼(gang)板卷的(de)(de)生(sheng)產(chan)企(qi)業。

 ④. 與伊(yi)斯貝格廠一樣(yang)，J&L公司(si)也是較早(zao)建成(cheng)一條緊湊式連續冷軋(ya)退火酸洗生(sheng)產線，年產25萬(wan)噸冷軋(ya)不(bu)銹鋼板卷的生(sheng)產企業。

 于齊諾爾公司的不銹(xiu)鋼產品(pin)主要有大方坯、小方坯、板坯、熱軋帶鋼、熱軋退火酸洗薄板和帶卷、冷軋薄板和帶卷、光亮退火薄板和帶卷，線材以及圓鋼、光亮棒材。
