本文论述的铝合金等温挤压法,与传统的铝舍金挤压完全不同。在等温挤压中,铝挤压件在全长范围内,机械性能和组织结构都很稳定;另外,可淬性铝制品在挤出模口时,可以进行淬火处理。为保证挤压温度均匀、稳定,对操作者提出了控制有效温度和速度的更高要求。B.M.Gotlib 等研制了一种计算机模型,可确定不同挤压速度、不同锭坯和不同挤压筒温度的挤压锭坯的温度范围。
This article discusses the aluminum isothermal extrusion method, with the traditional alchemy gold extrusion is completely different. In isothermal extrusion, the aluminum extrusion in the full-length range, mechanical properties and organizational structure are stable; In addition, hardenability of aluminum products in the extrusion die can be quenched. In order to ensure the extrusion temperature is uniform, stable, the operator raised a higher effective temperature and speed control requirements. B.M.Gotlib other developed a computer model to determine the different extrusion speed, different billet and extrusion cylinder temperature extrusion billet temperature range.
