Wearable steel ball with reinforced framework

[0013] Such as figure 1 and figure 2 as shown, figure 1 It is a structural schematic diagram of an embodiment of the framework-reinforced wear-resistant steel ball proposed by the present invention; figure 2 It is a structural schematic diagram of another embodiment of the framework-reinforced wear-resistant steel ball proposed by the present invention.

[0014] refer to figure 1 , in one embodiment, a skeleton reinforced wear-resistant steel ball proposed by the present invention includes a skeleton 2 made of high-strength and high-toughness alloy steel and a metal matrix 1 cast on the skeleton 2 by casting ductile iron, and the skeleton 2 is One-piece structure, the skeleton 2 divides the internal space of the steel ball into multiple spaces, the metal matrix 1 fills the interior of the skeleton 2, and forms a package for the skeleton 2; The center is radially arranged inside the steel balls to form the skeleton 2; after the skeleton 2 is made, it is placed in a mold, and
