Problems solved by technology

Although the existing copper alloy materials are competent, in some fields with harsh working environment, such as the rotating gear of the rotary kiln, its working environment is usually in a place of high temperature and high pressure; moreover, it is eroded by dust and corrosive gases; resulting in Ordinary high-temperature-resistant and wear-resistant copper alloys will wear out after 500 hours of operation; and the wear will increase rapidly, and the entire part will be scrapped after about 800 hours
[0003] Due to the high price of the wear-resistant copper alloy, it takes a lot of cost to replace it once; it increases the cost of the product, and the replacement of the drive gear requires the shutdown of the rotary furnace, and it takes at least 24 hours for the rotary furnace to extinguish and re-ignite; plus the replacement gear time, which drastically reduces productivity

Abstract

The invention provides a super-wear-resistant copper alloy material, belongs to the technical field of materials and particularly relates to a super-wear-resistant copper alloy material which can still keep good wear resistance and long service life on the condition of high temperature, dust and corrosive gas. The super-wear-resistant copper alloy material is prepared from, by mass, 0.15-0.58% of C, 1.7-3.0% of Si, 0.8-1.0% of Mn, 0.15-0.3% of P, 0.035-0.047% of S, 0.7-4.0% of Ni, 2.0-2.5% of Cr and the balance Cu and inevitable impurities.

Description

technical field [0001] The invention belongs to the technical field of metal materials, and in particular relates to a super wear-resistant copper alloy material. Background technique [0002] In the field of machinery, such as large rolling mills, the force is transmitted through the rotation between the nut and the screw; the materials of the nut and the screw are required to have high strength and good wear resistance. Although the existing copper alloy materials are competent, in some fields with harsh working environment, such as the rotating gear of the rotary furnace, the working environment is usually in a place of high temperature and high pressure; moreover, it is eroded by dust and corrosive gases; resulting in Ordinary high-temperature-resistant and wear-resistant copper alloys will wear out after 500 hours of operation; and the wear will increase rapidly, and the entire part will be scrapped after about 800 hours. [0003] Due to the high price of the wear-resi...
