What is the thermal conductivity of chromite sand?
Chromite sand has a relatively high thermal conductivity, which makes it widely used in the foundry industry. Specific thermal conductivity may vary depending on test conditions and sample characteristics. According to data, the thermal conductivity coefficient of chromite sand is approximately 0.937W/cmK3. This value indicates that chromite sand has good hot soup properties and can effectively transfer heat during the casting process, thereby increasing the cooling rate of the casting.
