AC6786 Brown Corundum Abrasive

Brown Corundum Abrasive Description

Brown Corundum Abrasive is a synthetic brown alumina produced by melting bauxite, coke (anthracite), and iron filings in an electric arc furnace. Composed primarily of Al₂O₃ (95.00%-97.00%), with trace amounts of Fe, Si, Ti, and other elements, Brown Corundum is one of the most basic yet highly effective abrasives. Its excellent grinding performance and versatility make it widely used across various industries. SAM manufactures Brown Corundum using both fixed and tilting furnaces, offering a variety of sizes and grades to meet customer needs.

Fixed furnace Brown Corundum has fewer crystal aggregates, larger crystal sizes, and a lower glassy content, offering excellent toughness, high wear resistance, and superior purity. The abrasives made from this type of corundum exhibit high chemical stability, high temperature resistance, uniform particle sizes, and stable product quality, making them ideal for various abrasive tools, especially coated abrasives.

Brown Corundum Abrasive Applications

1.       Refractory Materials:

Both types of Brown Corundum are widely used in the production of refractory bricks and other heat-resistant materials due to their high temperature resistance and chemical stability.

2.       Metal and Alloy Processing:

Used for grinding and polishing metals and alloys, particularly in applications requiring high precision and durability. It is effective in machining steel, iron, aluminum, and other hard materials.

3.       Ceramics and Glass Manufacturing:

Brown Corundum abrasives are also utilized in the production of ceramic products, glass manufacturing, and other industrial applications where surface finishing is critical.

4.       Blasting and Surface Preparation:

Brown Corundum is used in sandblasting and surface preparation for cleaning, roughening, and finishing the surfaces of metals, concrete, and stone.

5.       Polishing and Surface Finishing:

Due to its sharp edges and wear resistance, it is commonly used for surface finishing and polishing applications in various industries, including automotive, aerospace, and manufacturing.

Precautions

1.       Particle Size Selection: Choose the appropriate particle size of brown corundum abrasive based on the processing requirements. For rough processing, it is recommended to use larger particle sizes; for fine processing, smaller particle sizes should be selected. This helps improve processing efficiency and surface quality.

2.       Operating Environment: Ensure proper ventilation in the work environment when using brown corundum abrasives to minimize dust accumulation. Although brown corundum produces less dust, protective measures, such as wearing dust masks, should still be taken to prevent health risks to workers.

3.       Tool Matching: When using brown corundum abrasives, select the appropriate grinding tools, such as inkjet machines or polishing machines. Ensure that the hardness of the tools matches the abrasives to avoid equipment damage or reduced abrasive efficiency.

4.       Safety Protection: Since brown corundum abrasives have high hardness and sharp edges, wear appropriate protective equipment (such as safety goggles, gloves, etc.) to prevent cuts or eye injuries.

5.       Temperature Control: When using brown corundum abrasives at high temperatures, ensure that the temperature is within a suitable range to avoid negatively affecting the abrasive performance or causing unnecessary wear.

6.       Service Life: Regularly check the wear of the brown corundum abrasives. While brown corundum has excellent wear resistance, abrasives will still experience wear over time. Timely replacement is necessary to maintain optimal processing performance.

7.       Waste Disposal: Dispose of waste materials generated after use according to environmental regulations to prevent pollution.
