 阿塞洛公(gong)司及其五(wu)個控股的不銹鋼子(zi)公(gong)司的生產工藝流程(cheng)舉例如(ru)下(xia)：

上述幾個工藝流程(cheng)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銹鋼(gang)帶，從而縮短了工序，降低了成本。

 ②. ALZ公司采用三步法(fa)冶(ye)煉工藝，連(lian)鑄的板(ban)坯(pi)經熱(re)連(lian)軋（外(wai)廠(chang)加(jia)工）后在本廠(chang)2套冷軋機上冷軋，然后退火(huo)、酸洗、精整。

 ③. ALZ公司擁有(you)目(mu)前世界(jie)上惟一能生產2000mm寬、厚度(du)可(ke)達到8mm冷(leng)軋(ya)不(bu)銹(xiu)鋼(gang)卷的生產線(xian)，也是世界(jie)上少數(shu)幾家可(ke)生產寬度(du)達2000mm熱軋(ya)不(bu)銹(xiu)鋼(gang)板卷的生產企業(ye)。

 ④. 與伊(yi)斯貝格廠一樣，J&L公司(si)也是(shi)較早建成一條(tiao)緊湊式連續冷軋(ya)退火酸洗(xi)生產線，年產25萬噸冷軋(ya)不銹鋼(gang)板卷的生產企業(ye)。

 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。
