Embodiment

[0037] The steel materials in Table 1 are selected respectively, and the end cover of the magnetic separator is manufactured according to the method for preparing the end cover of the magnetic separator.

[0038] Table 1: Composition table of the end cover of each magnetic separator (each component is calculated by weight ratio)

[0039]

[0040] The mechanical performance test, service life and surface performance of the end caps of the magnetic separator made of the above-mentioned different composition steels were compared. The specific results are shown in Table 2.

[0041] Table 2: Performance test table of end caps of magnetic separators in Examples 1 to 3 and Comparative Examples 1 and 2

[0042]

[0043] Through actual tests, it is found that: 1. The structure of the end cover of the magnetic separator made of traditional materials is austenite and a small amount of martensite and ferrite, and there is magnetism. A small amount of austenite is transformed into martensite after ...

Abstract

The invention provides a magnetic separator end cap and a manufacturing method of the magnetic separator end cap. The end cap is made of steel comprising the following chemical components, by weight, 0.08-0.12 part of C, 1.5-2.0 parts of Mn, 17-20 parts of Cr, 8-11 parts of Ni, 0.1-0.2 part of N, 0.5-0.9 part of Nb, at most 1.5 parts of Si, at most 0.03 part of S, at most 0.04 part of P and the balance Fe. The structure of the magnetic separator end cap is a single austenite, does not change after machining, is still the single austenite after machining and has no magnetism. The machine surface of the end cap is smooth, high in precision and good in quality.

Description

Technical field [0001] The invention relates to component parts of a magnetic separator, and in particular provides an end cover of a magnetic separator and a preparation method thereof. Background technique [0002] The end cover is an important component of the magnetic separator. It is located at both ends of the magnetic separator. Since the magnetic separator is a magnetic separation machine for separating magnetic minerals, the requirements for the magnetic field distribution gradient inside the magnetic separator are very strict. The end cover of the separator is magnetic, which will disturb the magnetic field distribution in the magnetic separator and affect the normal operation of the magnetic separator. The traditional materials for making end caps are made of steels composed of C, Si, Mn, S, P, Cr, Ni, Ti, and Fe. However, in the course of use, it is found that the end caps made of these materials have a structure To the west, there is a small amount of martensite and...
