全球铝轧制工业概览系列综述之六 世界铝板带热连轧技术(2)

A Review of Global Aluminium Plate and Strip Hot Roughing-Finishing Tandem Rolling Lines

对全世界4辊可逆式热粗轧与4辊双卷取热精轧生产线(1+1式)及多机架热连轧生产线即(1+3)式至(1+6)式轧机作了全面简明的介绍。严格来说,(1+1)式热轧制机列虽不能算热连轧生产线,但为了叙述系统起见,仍在本文中予以简介。中国现有(1+1)式热粗/精轧生产线1条,在建的(1+4)式热粗/连轧生产线1条,国家经济贸易委员会批准立项建设的(1+4)式热连轧生产线1条,拟建的在作立项前期准备工作的(1+4)式热连轧生产线二三条。全球有4辊热粗轧/1～6机架热精轧机生产线47条,其总生产能力约18300kt/a。

The global aluminium plate and strip hot roughing/finishing tandem rolling technology was reviewed.There are about 50roughing/finishing tandem rolling lines in the world by2000.The capacity of them is about 18300kt /a.Most of them are in the industry developed countries,only five lines in the developing countries.The first4high hot roughing/4stands tandem finishing mill commission in2002,and also there are2or3this lines which could be constructed in China in the future.
