Brown corundum is a high-temperature refractory material synthesized by capacitor synthesis from natural bauxite as raw material, which is refined and refined through high-temperature smelting in an electric arc furnace. Due to its high hardness, purity, and strong grinding ability, it has become one of the most basic grinding and polishing consumables. Meanwhile, in addition to being used as an abrasive, brown corundum also has high corrosion resistance and high temperature resistance, and is widely used in the production and processing of durable materials
However, in recent years, with the increase of manufacturers producing brown corundum, the quality of bauxite has declined, and electricity costs have continued to increase, the production cost of brown corundum is facing great pressure. In addition, market competition is fierce, profits are gradually decreasing, and product quality is also gradually declining. The quality is unstable, and phenomena such as powdering and cracking often occur, which has become a common problem of brown corundum and a fact that refractory material manufacturers find difficult to accept.
The characteristic of brown corundum is that it contains a lot of impurities, is brown in color, has high hardness and good toughness, can withstand large grinding forces, and is suitable for grinding materials such as carbon steel, alloy steel, stainless steel, hard bronze, etc. It is also inexpensive and widely used. The main content of brown corundum is 15% -25%, and what is the difference between the two? 15% brown corundum grinding stone has a darker surface color and less brown corundum sand content. Therefore, during the re grinding process, although the cutting force is sufficient, it is extremely wear-resistant. The ground product has more water stains, which affects the production environment and makes it difficult to pass environmental testing; The brown corundum grinding stone with a 25% content has a lighter color, a higher content of brown corundum sand, stronger grinding force, and less water and mud stains after grinding, which can be monitored through environmental protection
Brown corundum grinding stones are divided into oblique cylindrical, oblique triangular, triangular, and spherical shapes, with different material specifications and sizes. The selection of shape and specifications mainly depends on the customer's own workpiece material and the requirements to be met
