一种较好的压延材料应该具有延伸率高,单位压料力大,抗拉强度高,屈服点低等特点。而铝及其合金的性能与上述却相差太远(见表一)。从上表可知,铝及其合金有二个特点。第一,单位压料力小。第二、抗拉强度低、Ly12M 仅是08钢的一半,纯铝更低,因此,给铝质材料的压延带来困难。首先,由于单位压料力小,如何消除过渡形状的痕迹成为问题。

A good rolling material should have the characteristics of high elongation, large unit pressing force, high tensile strength and low yield point. The performance of aluminum and its alloys is far from the above (see Table 1). From the table shows, aluminum and its alloys have two characteristics. First, the unit pressure is small. Second, low tensile strength, Ly12M is only half of 08 steel, pure aluminum is lower, therefore, to the rolling of aluminum materials to bring difficulties. First of all, how to eliminate the trace of the transitional shape is a problem due to the small unit load.
