 阿塞洛公(gong)司(si)及其五個控股的不銹鋼子公(gong)司(si)的生產工藝流程(cheng)舉例如下：

上述(shu)幾個工藝流(liu)程的(de)特點可以概括(kuo)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(re)軋(ya)不銹鋼卷加工成冷(leng)軋不銹鋼(gang)帶，從而縮短了工序，降低了成本。

 ②. ALZ公司采用三(san)步法(fa)冶煉工藝，連鑄的板坯經(jing)熱連軋(ya)（外廠(chang)加工）后(hou)在本(ben)廠(chang)2套冷軋(ya)機上冷軋(ya)，然后(hou)退火(huo)、酸洗、精整。

 ③. ALZ公司(si)擁有目前世界上(shang)惟一能生(sheng)(sheng)產2000mm寬(kuan)、厚度可(ke)達(da)到8mm冷軋不銹鋼卷的生(sheng)(sheng)產線，也是世界上(shang)少數幾家(jia)可(ke)生(sheng)(sheng)產寬(kuan)度達(da)2000mm熱軋不銹鋼板卷的生(sheng)(sheng)產企(qi)業。

 ④. 與(yu)伊斯(si)貝格廠(chang)一樣(yang)，J&L公司也是較早(zao)建成(cheng)一條緊湊式連續冷(leng)軋退火酸洗生(sheng)產(chan)線，年產(chan)25萬噸(dun)冷(leng)軋不銹鋼板卷的生(sheng)產(chan)企業。

 于齊諾爾公司的不銹鋼產品主要有大方坯、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。
