 阿塞洛公司及其五個控股的不銹鋼子公司的生產工藝流程舉例(li)如下：

上述幾個工藝流程的(de)特點可以(yi)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軋不銹鋼卷加工成冷(leng)軋不銹鋼帶，從而縮短了工序，降低了成本。

 ②. ALZ公(gong)司采用三(san)步法冶煉工(gong)藝，連鑄的板坯(pi)經熱連軋（外廠加工(gong)）后在(zai)本廠2套(tao)冷(leng)(leng)軋機上冷(leng)(leng)軋，然后退火、酸洗、精整(zheng)。

 ③. ALZ公司擁有目前(qian)世界上惟一能生產2000mm寬、厚度可達到8mm冷軋(ya)不(bu)銹鋼(gang)卷的生產線，也是世界上少數幾家可生產寬度達2000mm熱軋(ya)不(bu)銹鋼(gang)板(ban)卷的生產企業。

 ④. 與伊斯貝格廠一樣，J&L公司也是較(jiao)早建成一條緊湊式連續(xu)冷軋退火酸洗生產(chan)線，年產(chan)25萬噸冷軋不銹(xiu)鋼板卷的生產(chan)企業(ye)。

 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。
