Abstract

A preparation method of a magnetic rod comprises the steps: A, weighing the following raw materials by weight: 20-40 parts of a rare earth permanent magnet, 10-30 parts of iron oxide, 20-40 parts of manganese oxide, 20-40 parts of zinc oxide, 10-30 parts of titanium dioxide and 10-30 parts of cobalt oxide, uniformly mixing and stirring the raw materials, adding 10-30 parts of nickel oxide and thenadding an insulating agent, and uniformly stirring the raw materials again to obtain a first mixed material; B, performing the smelting of the first mixed material at the step A to prepare an ingot,and obtaining a second mixed material; C, profiling the second mixed material; D, putting the profiled material into a sintering furnace to be tempered; E, grinding and cutting the tempered material at the step; F, electroplating and magnetizing the formed material at the step E to obtain the finished magnetic rod. The production process of the magnetic rod is simplified, the magnetic rod is not rusted in the long-term use process, and the service life of the magnetic rod is prolonged.

Description

technical field [0001] The invention relates to a preparation method of a magnetic rod, in particular to a preparation method of a magnetic rod. Background technique [0002] Magnetic rods are mainly used to filter various fine powders and liquids, iron-containing impurities in semi-liquids and other energy and magnetic substances. Currently, they are widely used in chemical, food, waste recycling, carbon black and other fields.
