一、前言冷轧取向硅钢片有两个主要性能参数,即磁感应强度和铁损。测量磁感强度一般采用艾布斯坦方圈,这种方法在工业生产中被广泛采用。然而测得的磁感应强度实际上是一个平均值,与某块样品的实际情况可能有差距。精确的测定方法是采用单片或双片测磁,但是这种设备在很多单位不一定具有。在研究冷轧取向硅钢片成品织构时,由于晶粒粗大,一般采用X射线劳埃法或腐蚀坑法,逐个测出每个晶粒的取向。在研究织构之后,有时还需要知道其磁感应强度。本 I. Introduction Cold-rolled oriented silicon steel sheet has two main performance parameters, namely, magnetic induction and iron loss. Magnetic induction generally used to measure the square Erbazuan circle, this method is widely used in industrial production. However, the measured magnetic flux density is actually an average value, which may be different from the actual situation of a certain sample. The exact method of measurement is to use either monolithic or bi-polar magnetometry, but such devices may not necessarily be available in many units. In the study of the cold-rolled oriented silicon steel sheet finished texture, due to coarse grains, the general use of X-ray Lao method or corrosion pit method, one by one to measure the orientation of each grain. After studying the texture, sometimes need to know the magnetic induction. this
