摘要
2017年,中国挤压铝材总产量19500kt,其中工业材产量10140kt,占总产量的52%。渤海湾地区产量1860kt,占工业材总产量的18.3%。本地区有忠旺集团等7个大型工业材挤压企业,生产能力约1600kt/a;中小工业材企业生产能力约545kt/a;建筑与结构材企业附带工业材生产能力约300kt/a;工业材产能总计约2450kt/a,约占全国总产能30000kt/a的8.2%。渤海湾地区有小到5MN的挤压机,也有大到天下独有的225MN挤压机,可以生产工业上所需要的超宽超大挤压材。
In 2017,China's total output of extruded aluminum was 19 500 kt ,of which the production of industrial materials was 10 140 kt,accounting for 52% of the total.The production in Bohai Bay region was 1 860 kt,accounting for 18.3% of the total industrial production.In Bohai Bay region,the production capacity of Zhongwang Group and the other six large-sized extrusion enterprises producing industrial materials is about 1 600 kt/a;the production capacity of small and medium-sized enterprises is about 545 kt/a;the production capacity of industrial materials produced by building and structural materials enterprises is about 300 kt/a;the production capacity of total industrial materials is about 2 450 kt/a,accounting for 8.2% of the national total production capacity of 30 000 kt/a.There are extruders as small as 5 MN and as large as 225 MN in this region.This large extruder is unique in the world,which can produce super wide and super large materials needed by the industry.
