Influence of Baking on Thermal–Expansion Ability of Quartz Sands
In order to understand the changing tendency of thermal–expansion abilities of used sands in foundry, the four groups of quartz sands were measured in this paper. The influencing laws of baked-times and temperatures on the property of quartz sands were analyzed. And the test results showed that volume thermal-expansion ratio of quartz sands decreases with increasing of the baked-times.
