[0002] The prior art reports that composite wear-resistant castings are manufactured using a medium bimetallic casting process. This type of composite wear-resistant castings ensures the excellent wear resistance of the wear-resistant part and also has the advantage of strong overall toughness. However, the wear-resistant castings produced by this process The composite strength of the casting is not high, and the composite area is only 80%, so there are still great safety hazards in the use of its parts, so it can only be used for wear-resistant castings in a static state, such as liners, while moving Wear-resistant castings such as hammer heads in

Embodiment Construction
[0009] A composite wear-resistant casting, the casting is provided with two risers, two riser necks and an overflow outlet, one of the risers is arranged on the upper part of the casting, and the other riser passes through two The riser neck is connected to the upper and lower parts of the side of the casting, and the overflow port is arranged on one side of the casting. The casting is composed of an assembly part 1 and a working part 2 cast from different materials. The working part 2 is a high The anti-wear body, the assembly part 1 is a strong and tough body, and the casting is composited into a whole through the melting layer between the two.

The invention relates to a compound abrasion-resistant casting. Two gatings and risers, two riser necks and an overflow port are formed in the casting. One gating and riser is arranged on the upper portion of the casting, the other gating and rise is arranged on the upper and lower portions of the side of the casing through the two riser necks, and the overflow port is arranged on one side of the casting. According to the compound abrasion-resistant casting, a medium-free double-liquid three-dimensional compound casting process is used, two high-toughness and high-rigidity materials different in performances are compounded into a whole through a middle melting layer, the compound strength is firm, the compound area reaches 100%, parts have both high toughness and high rigidity, and deficiencies that materials are single and high toughness and high rigidity cannot be provided simultaneously are effectively overcome.
Description
technical field [0001] The invention relates to the field of product casting, in particular to a composite wear-resistant casting. Background technique [0002] The prior art reports that composite wear-resistant castings are manufactured using a medium bimetallic casting process. This type of composite wear-resistant castings ensures the excellent wear resistance of the wear-resistant part and also has the advantage of strong overall toughness. However, the wear-resistant castings produced by this process The composite strength of the casting is not high, and the composite area is only 80%, so there are still great safety hazards in the use of its parts, so it can only be used for wear-resistant castings in a static state, such as liners, while moving Wear-resistant castings such as hammer heads are not suitable. Contents of the invention [0003] The purpose of the present invention is to provide a composite wear-resistant casting that can simultaneously meet the requir...
