Structure of carbide steel rod embedded in steel matrix and composite casting process

Abstract

The provided is a structure of carbide steel rod embedded in steel matrix, including the steel matrix and at least one preform arranged in the steel matrix; the preform includes a substrate and a plurality of carbide steel rods fixed to the substrate; and the preform forms a metallurgically bonded mosaic structure with the steel matrix through a casting process, and spaces exist between the carbide steel rods and a working surface of the steel matrix. By forming the plurality of connecting holes on the substrate along a thickness direction, the carbide steel rods are sequentially assembled into the connecting holes and fixed by welding; and a fixed rod is vertically installed on a surface of the substrate, and a spatial positioning of the preform is realized by inserting the fixed rod into a mold cavity wall.
