specific Embodiment approach 1

[0012] Specific embodiment 1: In this embodiment, the wear-resistant alloy cast iron modified material is made of alloy cast iron and nano-rare earth modified material, and the nano-rare earth modified material accounts for 0.01-5.00% of the total weight of the wear-resistant alloy cast iron modified material. The alloy cast iron is Cr-Mo-Cu alloy cast iron, W-Cr-Cu alloy cast iron, W-Cr-Cu-Mn alloy cast iron, Cr-Mo-Cu-Ni alloy cast iron, Mo-Ni alloy cast iron, gray cast iron , White cast iron or ductile iron. The nano-rare earth modified material is a rare earth element and / or a rare earth compound with a particle size of 1 to 500 nm.

[0013] When the rare earth modified materials in this embodiment are a mixture, various rare earth modified materials can be mixed in any ratio.

specific Embodiment approach 2

[0014] Specific embodiment two: this embodiment is different from specific embodiment one in that the nano-rare earth modified material accounts for 0.02-2.00% of the total weight of the wear-resistant alloy cast iron modified material. Others are the same as the first embodiment.

specific Embodiment approach 3

[0015] Specific embodiment three: This embodiment is different from specific embodiment one in that the nano-rare earth modified material accounts for 0.1% of the total weight of the wear-resistant alloy cast iron modified material. Others are the same as the first embodiment.

Abstract

The invention relates to a wear resistant alloy cast iron modified material and a method thereof of fabricating nog plate blank casting, pertaining to a sphere material fabrication technology. The problems of low grinding processing efficiency and short service life of present nog plate are solved. Wear resistant alloy cast iron materials are fabricated by cast iron and nano rare earth modified material. The nano rare earth modified material accounts for 0.01 to 5.00 percent of total weight of wear resistant alloy cast iron modified materials; alloy cast iron comprises Cr-Mo-Cu alloy cast iron, W-Cr-Cu alloy cast iron, W-Cr-Cu-Mn alloy cast iron, Cr-Mo-Cu-Ni alloy cast iron, Mo-Ni alloy cast iron, gray cast iron, white cast iron or ductile cast iron; the grain diameter of the nano rare earth modified material is 1 to 500nm of lanthanon and / or rare earth compounds; the nog plate blank casting fabricating method employs a melting casting method. The grinding processing efficiency of the nog plate fabricated by the wear resistant alloy cast iron modified material of the invention is higher than existing nog plate by more than 50 percent and the service life is twice or more as that of the existing nog plate and the application range is wide. The fabrication technic of the invention is characterized by simple technique and easy operation.

Description

Technical field [0001] The invention belongs to the manufacturing technology of spherical materials; in particular, it relates to a grinding plate modified material and a grinding plate blank for grinding and grinding spherical materials such as steel balls, tungsten alloy balls, ceramic balls, glass balls, agate balls and other handicraft balls. Method of casting manufacturing. Background technique [0002] The high-tech machinery industry needs high-precision, high-quality bearings and steel balls. In recent years, my country’s steel ball industry has made rapid progress and has become a world steel ball producer, but not a strong country. The main reason is that the steel balls produced in my country have high precision and quality. Less than the level of the world's strong steel ball production country. Therefore, improving the surface accuracy of steel balls in our country, producing high-quality steel balls, and building a world powerhouse of steel balls, is placed in front...
