Introduction to Foundry Sand
Foundry sand is a crucial raw material in the casting industry. It is used to create molds and cores for metal casting processes. The quality of foundry sand significantly impacts the final quality of castings. Good - quality foundry sand should have appropriate grain size, shape, chemical composition, and thermal properties. It needs to be able to withstand high temperatures during the casting process, maintain its shape, and provide a smooth surface finish for the castings. Different types of foundry sand, such as silica sand, olivine sand, and zircon sand, are used depending on the specific requirements of the casting.
