The Role of Cryolite in Grinding Wheels

Cryolite (chemical formula Na₃AlF₆ or KAlF₄) serves as a key active filler in resin-bonded grinding wheels, significantly enhancing wheel performance through synergistic physical and chemical interactions.

How is cryolite used in casting?

Sprinkle it onto the surface of the molten iron at a dosage of 0.1%–0.3%. Its functions include slag removal and surface coverage. Cryolite helps dilute the molten slag, making it easier to collect and remove. When heated above 1011°C, cryolite decomposes, releasing AlF3 gas. This gas can protect the surface of the molten iron from oxidation—but unfortunately, it is harmful to humans.

Analysis issues regarding cryolite quality

Cryolite, as the primary solvent in aluminum smelting, plays a critically important role during the electrolytic production process. The quality of cryolite not only affects the purity of the electrolytically produced aluminum but also directly influences the efficiency and overall performance of the entire electrolysis process. Therefore, accurate analysis and inspection of cryolite are essential to ensure optimal production outcomes.

The Difference Between Polymer Cryolite and Regular Cryolite

High-molecular-ratio cryolite refers to cryolite where the molecular ratio of sodium to aluminum fluoride content falls between 2.8 and 3.0. This type of high-molecular-ratio cryolite contains fewer impurities, boasts a higher cryolite recovery rate, and is particularly favored by customers who rely on cryolite for their operations.
