1980年末我们用单辊熔喷速凝法成功地喷制出宽度达200mm 的 Fe40Ni40P12B8 非晶磁性薄带.本文介绍在喷制非晶宽带时产生的各种工艺性缺陷的分类和特征,在大量实验的基础上,分析了缺陷产生的原因及各主要工艺因素的影响,并提出相应消除缺陷的方法.实验证明,正确的判别缺陷和分析产生的原因,对生产优质的非晶宽带是十分重要的. At the end of 1980, we successfully spun out the Fe40Ni40P12B8 amorphous magnetic ribbon with a width of 200mm by single-roll melt-blown rapid coagulation method.This paper introduces the classification and characteristics of various technological defects produced when sprinkling amorphous broadband, Based on the experiments, the causes of the defects and the influence of the main process factors are analyzed, and the corresponding methods to eliminate the defects are put forward.Experiments prove that the correct discrimination defects and the reasons for the analysis are very important for the production of high quality amorphous broadband of.
