### 1. What are graphite blocks used for in casting?

Graphite blocks are commonly used in the casting industry for their high temperature resistance, thermal conductivity, and self-lubricating properties. They are used in various casting processes such as die casting, continuous casting, and centrifugal casting. Graphite blocks are typically used as molds, crucibles, and dies in these processes due to their ability to withstand extreme temperatures and provide a smooth surface finish to the casted products.

### 2. How is graphite block different from other materials used in casting?

Graphite blocks have several advantages over other materials commonly used in casting such as steel, aluminum, and ceramic. One of the main differences is their high temperature resistance, which allows graphite blocks to withstand temperatures up to 5000°C without melting or deforming. This makes them ideal for casting processes that involve molten metals or alloys.

Another key difference is the thermal conductivity of graphite blocks, which allows for efficient heat transfer during the casting process. This helps in achieving uniform solidification of the casted products and reduces the risk of defects such as porosity or shrinkage.

Moreover, graphite blocks have a self-lubricating property, which reduces friction between the mold/die and the molten metal, resulting in smoother casting surfaces and longer mold/die lifespan. This property also helps in preventing metal sticking or adhesion to the mold/die during the casting process.

Overall, the unique combination of high temperature resistance, thermal conductivity, and self-lubricating properties make graphite blocks an ideal choice for various casting applications in the industry.
