本标准代替GB/T 2521-1996《冷轧晶粒取向、无取向磁性钢带(片)》。
本标准规定了公称厚度为0.23mm、0.27mm、0.30mm、0.35 mm的冷轧取向和公称厚度为0.35mm、0.50 mm、0.65 mm的冷轧无取向电工钢带(片)的分类、牌号、一般要求、技术要求、检查和测试、包装、标志和质量证明书等。本标准适用于全工艺状态供货、在磁路结构中使用的冷轧取向和冷轧无取向电工钢带(片)。
本标准与GB/T 2521-1996相比主要变化如下:
a)取向电工钢用两个表格分别表示普通级电工钢和高磁导率级电工钢,增加了0.23mm的厚度规格牌号;
b)普通级取向电工钢0.27mm 厚度规格增加了27Q110牌号,0.30mm厚度规格增加了30Q120牌号,删除了35Q165牌号;
c)高磁导率级取向电工钢0.27厚度规格增加了27QG090、27QG095、27QG105牌号,0.30mm厚度规格增加了30QG105牌号、删除了30QG130低牌号,0.35mm厚度规格增加了35QG115牌号;
d)将无取向电工钢50W540牌号修订为50W530牌号;
e)加严了厚度尺寸允许偏差;
f)增加了残余曲率条款和附录A《不平度、镰刀弯、毛刺高度和残余曲率的测试图》;
g)增加了“订货资料”条款;
h)增加了附录A、附录B、附录C。
