| 摘 要： | 针对磁介质在应用过程中出现弯曲变形的问题,需寻求既能表现出较高抗弯强度又能产生较高磁场力的磁介质。对几种特殊截面磁介质的磁场特性和抗弯强度进行了模拟和计算分析,并与常规圆形截面介质作对比,结果表明:几种特殊截面形状的磁介质产生的磁场力都要大于直径2 mm的圆形截面磁介质产生的磁场力;当量直径3 mm和4 mm的椭圆截面和正方形截面介质的抗弯强度比直径2 mm圆形截面介质大得多;几种介质中当量直径4 mm的正方形截面介质的抗弯强度和产生的磁场力都是最大的。

| Abstract: | Matrices which can generate high magnetic force and present high flexural strength should be developed because of the bending deformation of matrices when applied in high gradient magnetic separator. The magnetic characteristics and flexural strength of several special cross-sectional shape matrices are simulated and calculated and are compared with those of conventional circular cross-sectional shape matrices, the results show that: The magnetic forces generated by special cross-sectional shapes matrices are larger than those of the 2mm circular cross-sectional shape matrices; The flexural strength of elliptical and square cross-sectional shape matrices with equivalent diameters 3mm and 4mm are much larger than that of 2mm circular cross-sectional shape matrices; Square cross-sectional shape matrices with a equivalent diameter of 4mm can generate high magnetic force and present high flexural strength at the same time. |
