铝合金挤压制品通常采用加热正挤压法,在日本投入生产的挤压机目前已有数百台之多。加热正挤压加工硬铝类(如7075合金)、含镁量多的铝合金是非常困难的,生产率也是很低的。用静液挤压法挤压上述合金,正进行着大量的研究,但有关应用至今尚未发表。现介绍住友重机工业公司与我公司共同在1600吨挤压机上进行铝合金管材挤压的情况。 1600吨卧式油压挤压机系住友重机工业公司和英国Fielding &platt公司合作制造的。其主要参数为:
Aluminum extrusion products are usually heated positive extrusion method, put into production in Japan, there are now hundreds of extruders. Heating extrusion processing of hard aluminum (such as 7075 alloy), the aluminum content of more aluminum is very difficult, the productivity is very low. Extrusion of the above-mentioned alloy by hydrostatic extrusion is undergoing extensive research, but the application has not yet been published. Sumitomo Heavy Industries is now introduced with my company in 1600 tons of extrusion machines for aluminum extrusion pipe. 1600 tons of horizontal hydraulic extruder Sumitomo Heavy Industries, Ltd. and the United Kingdom Fielding & platt co-manufacturing. The main parameters are:
