日本的铝挤压工业

Aluminum Extrusion Industry in Japan

对日本的铝挤压产业作了全面、系统介绍。2017年日本的铝人均消费量约28kg;日本有11个大的挤压厂、30个中小型厂,保有生产能力约1370kt/a,挤压机约280台,但挤压力≤12MN的只有3台,仅有1台挤压力95MN重型挤压机,挤压力45MN^75MN的大挤压机只有13台。在2013-2017年的5年中,在日本发货的挤压材中,建筑材平均占60.8%,工业材平均占39.2%。日本挤压铝材消费高峰期已过,早已进入平稳期,近期产量约为800kt/a,产能利用率仅约58.4%。

In this paper,a comprehensive and systematic introduction is made to the aluminum extrusion industry in Japan.In 2017,the per capita consumption of aluminum in Japan is about 28kg;In Japan,there are 11 large extrusion plants,30 small and medium-sized plants with a production capacity of about 1370kt/a and about 280 extruders,but only 3 extruders 12MN and only 1 heavy-duty 95MN extruder under extrusion pressure.There are only 13 large extruders with extrusion pressure 45 MN^75MN.In the five years from 2013 to 2017,building materials accounted for an average of 60.8%of extruded materials shipped in Japan and industrial materials accounted for 39.2%on average.Japan's extrusion aluminum consumption peak has passed,has already entered a stable period,near-term production is about 800kt/a,capacity utilization rate is only about 58.4%.
