 阿塞洛公(gong)司及其五個控股的不(bu)銹鋼(gang)子公(gong)司的生產工藝流程舉(ju)例如下(xia)：

上述(shu)幾(ji)個(ge)工藝流程的特點可以概括為：

 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(bu)銹鋼帶，從而縮短了工序，降低了成本。

 ②. ALZ公司采用三(san)步法冶煉工(gong)藝，連鑄的板坯經熱(re)連軋(ya)（外(wai)廠加工(gong)）后在本廠2套冷軋(ya)機(ji)上冷軋(ya)，然后退火、酸(suan)洗、精整。

 ③. ALZ公(gong)司(si)擁有目前世界上惟一能生(sheng)(sheng)產(chan)(chan)2000mm寬、厚度可達到8mm冷軋不銹(xiu)鋼卷的生(sheng)(sheng)產(chan)(chan)線，也是(shi)世界上少(shao)數幾家可生(sheng)(sheng)產(chan)(chan)寬度達2000mm熱軋不銹(xiu)鋼板卷的生(sheng)(sheng)產(chan)(chan)企業。

 ④. 與伊斯貝格廠一樣，J&L公司(si)也是較(jiao)早建(jian)成一條緊湊式連續(xu)冷軋(ya)退火酸洗生產(chan)(chan)線，年產(chan)(chan)25萬噸(dun)冷軋(ya)不銹鋼板卷的生產(chan)(chan)企業。

 于齊諾爾公司的不銹鋼(gang)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。
