Problems solved by technology

Since the above-mentioned components mostly work under the conditions of high temperature, heavy load, and much dust, the existing self-lubricating alloy materials have a short service life. For example, the self-lubricating bearings in the continuous casting machine need to be replaced every 2-3 days, which not only causes The production cost is high, causing a lot of waste of resources, and frequent replacement is time-con

Example Embodiment

[0018] Table 1 shows the chemical composition of the five embodiments of the present invention.

[0019] example

[0020] The above-mentioned self-lubricating metal material can be made by powder metallurgy, and each component in the material is powder, including the following steps:

[0021] (1) The mixture is prepared according to the chemical composition and fully mixed, where iron is reduced iron powder with a particle size of 100 mesh, graphite particle size is 300 mesh, molybdenum powder particle size is 400 mesh, chromium powder particle size is 300 mesh, and copper powder particle size is 300 The sulphur powder has a particle size of 300 mesh.

[0022] (2) Pressing. The mixed materials are assembled according to the different components required. The pressing pressure is 6-7t / cm. 2 , The density of the compact after pressing should be greater than 6 g / cm3.

[0023] (3) Sintering Put the compact prepared in step (2) into the electric furnace, and pass protective ...

Abstract

The disclosed preparation method for self-lubricating alloy material comprises mainly: adjusting the sulfur content to improve product optimal lubrication effect, adding other alloy elements to reinforce ferrite. This product has strong wear-resist capacity to prolong its lifetime, and can also be prepared by powder metallurgy sintering with low cost.

Description

technical field [0001] The invention belongs to the field of metallurgy, and in particular relates to a self-lubricating iron-based alloy material and a preparation method thereof. Background technique [0002] Self-lubricating alloy materials are widely used in the metallurgical industry. For example, self-lubricating bearings and other related components in continuous casting machines must use self-lubricating materials. Since the above-mentioned components mostly work under the conditions of high temperature, heavy load, and much dust, the existing self-lubricating alloy materials have a short service life. For example, the self-lubricating bearings in the continuous casting machine need to be replaced every 2-3 days, which not only causes The production cost is high, resulting in a waste of a lot of resources, and frequent replacement is time-consuming and labor-intensive, which affects work efficiency. At present, the preparation of self-lubricating materials is mostly...
