Abstract

The invention discloses a crusher wear resisting hammerhead for a high-toughness impact resisting cast-penetrated composite ore. The crusher hammerhead consists of a basal body, and a cast-penetrated layer on the surface of the basal body, wherein the basal body consists of the following components in percentage by weight: 0.3-0.5% of C, 1.0-1.5% of Si, 0.5-1.0% of Mn, 14-16% of Cr, 0.8-1.0% of Mo, 0.5-1% of Cu, 0.05-0.1% of B, 1-2% of Al, S not more than 0.05%, P not more than 0.05%, and the balance of Fe. The crusher hammerhead is excellent in wear resistance, toughness and impact resistance, is few in casting defects, is high in appearance quality, and is excellent in durability.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a wear-resistant hammerhead of a high-toughness impact-resistant cast-infiltration compound mine crusher and a production method thereof. Background technique [0002] Hammer crusher is a commonly used equipment in the mining industry. As the hammer head of the crusher for crushing various materials, it will bear a large impact force and the extrusion of the material on the surface during the crushing process, resulting in great damage. wear and reduce service life. Therefore, the preparation of the crusher hammer must take into account the high hardness and good impact toughness, so as to improve the wear resistance of the hammer. [0003] Cast infiltration is to mix materials such as ceramic particles or alloy particles with binders and solvents, fix them on the surface of the mold, and then pour molten metal. The molten metal penetrates into the micropores and undergoes inte...
