我厂生产的铝板、带,百分之四十以上是供深冲热水瓶盖、底肩、铝锅等之用。由于轧制工艺的关系,常使板、带材产生各向异性,即织构,从而造成制品出现“四角”(即“制耳”),废品率增加,切边损失大(见图1)。为了有效地控制织构,提高产品的成品率,本厂在没有X射线衍射仪的情况下,采用拉伸和硬度试验法,定性而简易地测定铝材的织构,为控制产品质量取得了效果,具体方法如下: I plant the production of aluminum, with more than 40 percent for deep drawing hot water bottle cap, shoulders, such as the use of aluminum pan. Due to the relationship between the rolling process, often plate, strip anisotropy, that texture, resulting in products appear “four corners” (ie “ear system”), increased rejection rate, see picture 1). In order to effectively control the texture, improve product yield, the factory in the absence of X-ray diffraction instrument, the use of tensile and hardness test method, qualitative and simple determination of aluminum texture, in order to control the quality of the product made Effect, the specific method is as follows:
