Description

technical field [0001] The invention relates to the technical field of mechanical materials, and in particular provides a special high-performance die material for producing ore crushing mechanical equipment. Background technique [0002] In the process of screening and crushing ore in the mining industry, mining machinery is directly subjected to wear, impact, and vibration to produce different degrees of fatigue deformation, low hardness, poor corrosion resistance, non-wear resistance, and easy damage. Therefore, compared with other equipment In terms of high maintenance rate and shortened service life due to material failure, this not only consumes a lot of steel, but also wastes manpower and delays the construction period, resulting in serious economic losses. Non-metallic materials have high temperature resistance, oxidation resistance and corrosion resistance. Strong, good chemical stability, high wear resistance, etc., but there are still shortcomings such as poor the...

[0002] In the process of screening and crushing ore in the mining industry, mining machinery is directly subjected to wear, impact, and vibration to produce different degrees of fatigue deformation, low hardness, poor corrosion resistance, non-wear resistance, and easy damage. Therefore, compared with other equipment In terms of high maintenance rate and shortened service life due to material failure, this not only consumes a lot of steel, but also wastes manpower and delays the construction period, resulting in serious economic losses. Non-metallic materials have high temperature resistance, oxidation resistance and corrosion resistance. Strong, good chemical stability, high wear resistance, etc., but there are still shortcomings such as poor thermal shock resistance and limited wear resistance, which need to be improved. At the same time, it is necessary to continuously reduce production costs, realize the maximum benefits of the enterprise, and promote scientific and technological progress.
