Description

Technical Field

[0001] This utility model relates to the technical field of quartz sand processing equipment, specifically a molten quartz sand cleaning device for melt casting. Background Technology

[0002] Fused silica is produced by melting natural high-purity silica in an electric furnace at a temperature above 1760 degrees Celsius, followed by rapid cooling. This process transforms crystalline silica into an amorphous glass melt. Fused silica has a melting temperature of approximately 1713 degrees Celsius, a low thermal conductivity, and a coefficient of thermal expansion that is among the lowest of all refractory materials. As a result, it has extremely high thermal shock resistance. Therefore, fused silica shells rarely crack due to drastic temperature changes during firing and casting, making it an ideal refractory material for investment casting. It can also be used as a surface or back coating material, as well as a sand-spreading material.
