Problems solved by technology

[0006] In order to solve the problem that the polar ribs (4) of the existing metal magnetic lining are located at the Y−Y section of the magnetic lining working face with the highest magnetic field intensity, so that they stay in the shallow groove (6) surrounded by the polar ribs (4) and the transverse ribs (5). The protective layer ⑾ is interrupted at the Y−Y section with the highest magnetic field intensity, which weakens the firmness of the protective layer ⑾, thereby weakening the wear resistance of the magnetic lining and shortening its service life. The present invention proposes a Metal magnetic liner formed by reinforced protective layer

Abstract

A metal magnetic lining plate formed by reinforcing a protective layer for protecting the inner surface of a mill cylinder and the ferromagnetic metal surface of the material in contact with the material during material transportation to reduce the wear of the surface. The lining plate is composed of a casing (1), a magnetic block group (2) and an adhesive; wherein the casing (1) is made of a non-magnetic metal material, one side is a mounting surface, and is composed of a plurality of cubic lattices (3), and all lattices (3) are aligned horizontally and vertically. The other side is a workingsurface, which is surrounded by the pole rib plates (4) and the transverse rib plates (5) into shallow grooves (6). A magnetic block group (2) is placed in the lattice (3). The polarity direction ofthe magnetic block groups (2) loaded into the lattices (3) is such that the polarities of the same row of magnetic block groups (2) are the same, and the polarities of the adjacent two rows of magnetic block groups (2) are opposite. The pole rib plates (4) on the working surface of the outer casing (1) are located in a symmetrical center plane of a row of lattices (3) in which the magnetic block groups (2) of the same polarity are mounted. The above arrangement of the pole rib plates (4) allows the protective layer (11) residing in the shallow grooves (6) surrounded by the pole rib plates (4)and the transverse rib plates (5) to remain continuous in the region of the highest magnetic field strength, whereby the protective layer (11) is more strongly sucked in the shallow grooves (6), the magnetic liner working surface is better protected and the magnetic liner life is extended.
