Self-lubricating alloy material and method for preparing the same

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...

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-consuming and labor-intensive, which affects work efficiency

At present, the preparation of self-lubricating materials is mostly made by smelting metallurgy. Due to the limitation of smelting conditions, the chemical changes of various components in the production process are relatively complicated, the production process is not easy to control, and the adjustment of elements is difficult to adjust to the optimum. good condition
