Abstract

The invention relates to the field of composite steel plates, and particularly discloses a composite wear-resistant steel plate and a preparation method thereof. The composite wear-resistant steel plate comprises a base plate and a wear-resistant plate, wherein the wear-resistant plate is composed of the following components: Cr, Mn, Al, V, C, Zr, TiB2, MoSi2 and the balance Fe and inevitable impurities. The preparation method comprises the steps that Cr, Fe, Al, Mn, V, Zr and ethyl alcohol are mixed to form a first primary mixture; TiB2, MoSi2 and C are mixed to form a second primary mixture;the first primary mixture and the second primary mixture are mixed, heated, melted, pressed into a blank, annealed, cooled and ground to obtain a wear-resistant plate; and then the wear-resistant plate and the base plate are subjected to heating pressure welding to obtain the composite wear-resistant steel plate. The composite wear-resistant steel plate provided by the invention has the advantageof being good in wear resistance.

Description

technical field [0001] The application relates to the field of composite steel plates, more specifically, it relates to a composite wear-resistant steel plate and a preparation method thereof. Background technique [0002] Steel plate is a common steel in industrial production. With the continuous acceleration of industrial development, people have higher and higher requirements for steel plate. Steel plate needs to have better mechanical properties and mechanical strength, so that the steel plate can be used in the application process. play a greater role. [0003] In order to further enhance the performance of steel plates, people produce composite steel plates. On the basis of ordinary steel plates, ordinary steel plates are combined with another or more steel plates with better performance to improve the overall mechanical properties of the composite steel plates, so that they can be used At the same time as the ordinary steel plate, the mechanical properties of the ste...
