TLDR
In this article, a magnetic core main body composed of flat-shaped soft magnetic alloy material and insulator and a metal outer pipe accommodating said core is provided, and the flat surface of the soft magnetic Alloy material is orientated in the axial direction of the outer pipe.Abstract:
PURPOSE: To reduce magnetic gap, and improve magnetic characteristics, by providing a magnetic core main body composed of flat-shaped soft magnetic alloy material and insulator and a metal outer pipe accommodating said core, orientating the flat surface of the soft magnetic alloy material in the axial direction of the material outer pipe, and substantially constituting the soft magnetic alloy material in an amorphous state. CONSTITUTION: Magnetic core main body composed of flat-shaped soft magnetic alloy material and insulator and a metal outer pipe accommodating said core are provided, and the flat surface of the soft magnetic alloy material is orientated in the axial direction of the outer pipe. The soft magnetic alloy material is amorphous alloy expressed by Fe 100-a-b M a Y b . M is at least one kind of element selected out of group IV a , group V b elements in periodic table, and Mn, Co and Cu. Y is at least one of Si, B, P and C. The notations (a) and (b) represent at%, and adjustment is performed so as to satisfy 0≤a≤8 and 10≤b≤30. COPYRIGHT: (C)1992,JPO&Japioread more

Tension calculating method
TL;DR: In this paper, the authors propose to detect the tension acting on a rolling material between rolling mills with good accuracy and to eventually permit the tension control with high accuracy even with a rolling installation having no sensors for detecting rolling load by using only the rolling power to be outputted by the main motors of the rolling mills without using the rolling load.
