High-hardness alloy novel grinding material and manufacturing process thereof

Abstract

The invention discloses a high-hardness alloy novel grinding material and a manufacturing process thereof. The alloy novel grinding material comprises, by weight percent, 16%-30% of chromium, 1.5%-2.5% of carbon, 1.5%-2.5% of silicon, 0.8%-1.2% of manganese and the balance iron. The high-hardness alloy novel grinding material has the advantages of being higher in hardness, more resistant to wear and better in grinding effect.

Description

technical field [0001] The invention relates to the field of abrasive materials, in particular to a novel high-hardness alloy abrasive material and a manufacturing process thereof. Background technique [0002] Abrasive materials are the general term for coated abrasives, wire drawing abrasives, and polishing abrasives, which are mainly used for grinding, wire drawing and polishing on the surface of workpieces. Abrasive materials generally have high hardness, toughness and regular shape. When grinding and polishing the workpiece, because the purpose of the workpiece is different, the materials used in the workpiece are different. Therefore, the surface abrasive materials used in different materials are also different; when we are performing the surface treatment of the workpiece, According to the characteristics and requirements of the workpiece, it is necessary to select the polishing and abrasive material that best meets the requirements of the workpiece.

Problems solved by technology

[0003] For example, in the existing aluminum alloy products industry, there are many kinds of processing techniques for aluminum alloy products, among which casting and die-casting are the main ones. Casting-formed aluminum alloy workpieces have low surface hardness and soft texture; die-cast aluminum alloy workpieces The surface hardness is high and the texture is relatively hard; for the workpieces formed by these two processes, the abrasive materials used are also very different. For casting molded workpieces, alloy abrasive materials with ordinary hardness can meet the grinding requirements, but for die casting For molded workpieces, alloy abrasive materials with ordinary hardness cannot achieve a good treatment effect at all, and high-hardness abrasive materials must be used to treat burrs and other defects on the surface of die-casting workpieces

However, the grinding materials currently on the market are uneven, either the hardness requirements are not up to the standard, or they are not wear-resistant, the loss is large, the waste is serious, and the grinding effect is poor and the efficiency is low, which cannot meet people's requirements for high-hardness workpieces formed by die-casting. grinding needs
