Silicon carbide crucible and molten copper graphite crucible are introduced as follows

Analysis of Common Phenomenon of Silicon Carbide Crucible


    Phenomenon 1: Corrosion occurs at the position of the metal liquid level inside the silicon carbide crucible;


    Cause analysis: caused by additives and metal oxides floating on the metal liquid surface. Excessive oxidation and excessive use of additives should be avoided, and excessive heating should be avoided.


    Phenomenon 2: Corrosion occurs in many places inside the silicon carbide crucible;


    Cause analysis: Corrosion in many places inside the silicon carbide crucible is generally caused by corrosive substances. For example, the additive is put in when the casting material is not put in or not melted, or the additive is sprinkled directly on the crucible wall. We should use additives as prescribed and avoid overheating or overheating.


    Phenomenon 3: Corrosion occurs at the bottom or lower edge of the silicon carbide crucible;


    Cause analysis: This phenomenon is caused by coke or slag. The crucible can be damaged by using low-quality coke or by heating it at too high a temperature.


    Phenomenon 4: Depression on the surface of the silicon carbide crucible;


    Reason analysis: The additive penetrates and erodes the outer wall of the crucible with a higher temperature through the inner wall of the crucible.


   The molten copper graphite crucible is a kind of equipment that is used more in smelting factories and foundry enterprises. It has a particularly stable property, not only can resist the contamination of high temperature and high heat environment, but also has a better heat resistance. Conduction. It is also not easy to deform during use, and there is no problem of expansion when heated or shrinking when cold. Ideal for use in alternating hot and cold environments. Moreover, its chemical properties are also very stable, and it is not easy to be corroded and dissolved. The molten copper graphite crucible is manufactured by the world's most advanced cold isostatic pressing method, and the manufacturing pressure is 600MPa. It makes the internal organization of the product uniform and defect-free and has high strength.


    In today's metallization industry, the molten copper graphite crucible often has a high dissolution effect. The advantage is that such a crucible can promote the melting of metal substances even in a lower temperature environment. Therefore, it can be seen that such a crucible has very high oxidation resistance and constant temperature resistance. This is widely used in the production process.


    Compared with other products, the molten copper graphite crucible often does not have much pollution. After all, the graphite crucible product has low energy consumption, so it can ensure the green environmental protection effect of the product. Therefore, it is pursued by the public and its market demand is gradually increasing.
