挤压阶段变断面型材.变形程度是不同的,基本断面部分变形程度比较大,大头部分变形程度比较小.在生产断面一致的型材时.根据制品的长度采用不同能力的挤压机.例如,长度为1.5~7.5米的型材用直径210毫米的挤压筒在2000顿挤压机上挤压,长度为7.5~15米的型材分别用直径270和306毫米的挤压筒在3500吨和5000吨挤压机上挤压.另外,挤压温度也是不同的.?16合金型材,是将铸锭加热到380~460℃挤压.而B95合金型材是在380~440℃挤压.但是,在所有情况下,型材的大头部分和基本断面部分,不论是在纵向,还是在横向,其抗拉强度、屈服强度和相对延伸率都应当是?的.本文所研究的是,挤压温度和变形程度对115和B95合金阶段变断面型材机械性能和组织的影响.
Extrusion stage variable cross-section profiles. Deformation is different, the basic section of a large part of the degree of deformation, the bulk of the deformation is relatively small. In the production section of the same profile, according to the length of the product using different capabilities of the extruder .For example, Length of 1.5 to 7.5 meters of the profile with a diameter of 210 mm extrusion tube extrusion machine in the 2000 Dayton, the length of 7.5 to 15 meters of the profiles were 270 and 306 mm diameter extruder tube 3500 tons and 5000 tons In addition, extrusion temperature is also different.????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Case, the bulk of the section and the basic section of the section, whether in the vertical or horizontal, the tensile strength, yield strength and relative elongation should be? This study is the extrusion temperature and degree of deformation Effect on the mechanical properties and microstructure of 115 and B95 alloy cross-section profiles.
