1. Main raw materials and features
Main raw materials: Graphite crucibles are generally made of fine-grained graphite blocks or graphite columns.
Features:
High temperature resistance: Graphite crucibles can withstand extremely high temperatures to ensure that they will not deform or break due to high temperatures during the smelting of precious metals.
Strong thermal conductivity: Graphite crucibles have good thermal conductivity, which helps to evenly distribute heat during the smelting process and improve smelting efficiency.
Good corrosion resistance: Graphite crucibles have strong corrosion resistance to acidic and alkaline solutions, have excellent chemical stability, and do not participate in any chemical reactions during the smelting process.
Smooth inner wall: The inner wall of the graphite crucible is smooth, and the molten metal liquid is not easy to leak and adhere to the inner wall of the crucible, so that the metal liquid has good fluidity and castability, and is suitable for casting and molding in various molds.
2. Specifications
Specifications: Graphite crucibles come in a variety of sizes and shapes to meet the needs of different precious metal smelting.
3. Application and precautions
Application: Graphite crucibles are widely used in the smelting and refining of precious metals, as well as the smelting of non-ferrous metals and their alloys.
Precautions:
Before use, check whether the graphite crucible is damaged or cracked to ensure safe use.
The graphite crucible should be stored in a dry and ventilated place to avoid moisture that may damage the glaze layer or reduce the smelting efficiency.
During the smelting process, avoid spilling or splashing the metal liquid onto the outside of the graphite crucible to avoid damage to the crucible or cause safety accidents.
After smelting, the graphite crucible should be allowed to cool naturally to room temperature before cleaning and maintenance.
4. Maintenance and care
Regular cleaning: Use special tools to clean the graphite crucible while it is hot, and avoid using hard objects or sharp tools to scratch the inner wall of the crucible.
Moisture-proof treatment: The graphite crucible should be stored in a dry environment to avoid moisture that may damage the glaze layer or reduce the service life.
Regular inspection: Regularly check the integrity and use of the graphite crucible. If damaged, it should be replaced in time.
