November 06 , 20243 Common Alumina Abrasive Grains Reprocessing Methods and Performance Improvement Comparison
Alumina abrasives are widely used in metal processing, grinding, cutting and other industrial fields. In particular, due to their high hardness and wear resistance, they have become the preferred material for many high-precision grinding. However, the original alumina abrasive grains often require further processing to improve their performance and meet different processing requirements. Reprocessing can improve the grains morphology, size distribution, hardness, toughness and other characteristics, there by enhancing their performance under different working conditions. As a supplier with 30 years of production experience, we will explore several common alumina abrasive particle reprocessing methods in depth, and analyze the performance improvements brought by these processing methods through actual comparison. 1. Heat Treatment Process The heat treatment (calcination treatment) can improve the hardness, toughness and wear resistance of alumina abrasive particles by high-temperature heating. The specific process is as follows: The abrasive is directly calcined at a high temperature of 800-1300℃ for 2-4 hours, taken out and cooled, and can be used. If the temperature is high, some abrasives will have a small amount of sintering phenomenon, and they need to be broken and sieved before use. Performance Improvement The fine cracks formed by multiple impacts during the granulation process of the abrasive...
