Continuous Casting Graphite Molds Used for Metal Smelting Industry

Good High Temperature Resistance Graphite Continuous Casting Mold for Precious Metal Refining
1. Advanced production methods, such as direct continuous (or semi-continuous) production of rods or pipes from the molten metal state. Artificial graphite is considered to be the most suitable material for continuous or semi-continuous casting of non-ferrous metals. Production practice has proved that the use of graphite mold continuous casting industry, due to its good thermal conductivity, thermal conductivity determines the solidification rate of metals or alloys), the mold's good self-lubricating performance factors not only make the casting speed, but also due to the ingot The size is precise, the surface is smooth, and the crystal structure is uniform. It can be directly used in the next process. This not only greatly improves the yield, but also reduces the loss of waste products, while also greatly improving the quality of the product.
2. There are two continuous casting methods: vertical continuous casting and horizontal continuous casting.
3. Continuous casting graphite molds are also used in the metal smelting industry. Graphite molds can be used to cast molten metal. Graphite molds can be reused, but some designs can only be used once. Precise and creative small grain castings can be directly used in graphite molds.
4. The coefficient of thermal expansion is an important factor in determining the use of graphite as a mold material. The mold is a medium with very uneven temperature, heated from the inside by the molten material, and then cooled from the outside through the cooling process applied to it. Graphite has a low coefficient of thermal expansion, so that the mold can work normally without deformation or cracking. Another very important factor is self-lubrication. Graphite is a solid lubricant that produces low friction between the mold and the casting material. Then the graphite can be smoothly removed from the casting.
5. There are many factors that determine the life of continuous casting graphite molds. From the composition of the casting material, to the casting temperature, to the cooling rate, it will affect the life of the graphite mold. The specific grade of graphite used is also determined by many factors. The main factor is the field of material technology used in the casting mold. For example, for gray cast iron or high-nickel alloys, wear-resistant graphite is required, while for brass, relatively dense graphite is required. Graphite with sufficient porosity to allow zinc to evaporate would be a better choice.
6. Graphite molds designed for continuous casting need to consider all these factors and apply them to your specific application. Grade selection is the most important, and should include the opinions of casting personnel, graphite manufacturers, and machine factories specializing in graphite processing. Even so, when designing a new system, actual testing may be required before the actual graphite grade can be selected.
