High-efficiency extra strength alloy steel moderate grinding abrasive band and detection method thereof

Abstract

The invention relates to an abrasive band, in particular to a high-efficiency extra strength alloy steel moderate grinding abrasive band and a detection method thereof. The abrasive band comprises a base material, base adhesive, grinding material and composite adhesive, wherein the base adhesive comprises the following components in percentage by weight: 60-85 percent of bonding agent, 12-32 percent of neutral or alkaline inorganic filler, 0.1-0.3 percent of surface active agent and 2.5-8 percent of thinner; and the composite adhesive comprises the following components in percentage by weight: 65-85 percent of a bonding agent, 0-30 percent of inorganic filler, 2-5 percent of dyes and 2-8 percent of thinner. In the detection method, annulus band grinding is used for detecting demetallization amount, annulus bands are abutted, and ten stainless steel bars with the diameter of 40 cm are ground under the condition that the rotation speed is 1800 rpm, the contact pressure is 200 Newton and the grinding time is 71 seconds. The high-efficiency extra strength alloy steel moderate grinding abrasive band has high grinding performance and high performance price ratio, is suitable for moderate grinding processing of various alloy steel products, and can substitute similar imported products.

Description

technical field [0001] The invention belongs to the field of coated abrasive tools, and relates to an abrasive belt, in particular to a high-efficiency super-strength alloy steel medium abrasive belt and a detection method thereof. Background technique [0002] In the grinding of metal products, zirconium corundum products are generally used for rough machining, and calcined alumina high-efficiency abrasive belt products are often used for intermediate grinding. Metal products mostly use alloy steel as the most difficult grinding object. On the one hand, there are many types of them. On the other hand, the alloying elements in alloy steel generally increase the hardness of steel, making it have high strength, high toughness, wear resistance, and wear resistance. Special properties such as low temperature and high temperature resistance, thus increasing cutting resistance and easily aggravating tool wear. At present, calcined alumina high-efficiency abrasive belt products ar...

Problems solved by technology

Metal products mostly use alloy steel as the most difficult grinding object. On the one hand, there are many types of them. On the other hand, the alloying elements in alloy steel generally increase the hardness of steel, making it have high strength, high toughness, wear resistance, and wear resistance. Special properties such as low temperature and high temperature resistance, thus increasing cutting resistance and easily aggravating tool wear

At present, calcined alumina high-efficiency abrasive belt products are mostly imported, such as Japan’s NCA’s X871, Riken’s 953 and other products. Compared with the domestic market, imported products still have two problems: on the one hand, the price is high; on the other hand, The product is fixed, resulting in little room for performance improvement, and some fields are gradually unsuitable
