世界铝合金(国外英文资料) The world aluminum extrusion process equipment is toward large-scale, modern production lines, motors, and automation direction, a large round, flat extrusion container and special mold technical breakthrough progress has been made; Although China has become the worlds pressing power, but it is not squeeze the power, and industrial developed countries, Chinas aluminum extrusion technology and equipment have a certain gap. The extrusion equipment mainly refers to the extruder and its supporting equipment, which is an important indicator of the technical level. Rough statistics, countries all over the world have been equipped with different types, structure, USES and pressure of extruding machine more than 7000 units, including the United States more than 600 Taiwan, Japan, Russia, more than 400, more than 200 Taiwan, Germany in China more than 3000 sets, but most of them 15-25 mn between small and medium-sized extrusion machine. With large transport aircraft, bombers and missiles, ships and other military industrial and underground railway, high-speed train, etc. The development of modern transportation, need a lot of whole wall components, such as structure towards large-scale extruding machine. In the early 1950 s, the U.S. air force decided to use government money to build a series of heavy extrusion and forging press, the original proposed manufacturing 17 large pressure machine, cut to 9, after the 350 mn vertical forging - a extrusion machines, 120 mn and 80 mn aluminium each two horizontal extrusion machines. The present situation of the world aluminum extrusion technology Extruding equipment to the development of large-scale development After decades of development, it has formally put into production around the world use each of about 20 large extrusion machines, they are in the United States, Russia, China, Japan and Western Europe. The largest is the former Soviet union kuibyshev aluminum processing plant of 200 mn extruder, the United State
