Q: Why are there too many impurities in the gravity casting products of aluminum alloy, so they can not be welded well by argon arc welding?: 1. to improve the gating system, an open gating system must be used.2., strengthen the refining process of aluminum liquid, fully let the slag in the aluminum liquid separate out.3. as far as possible the use of low temperature pouring.If it's convenient, I can help you with the craft.

Q: Are there different sizes available for graphite crucibles?: Yes, there are different sizes available for graphite crucibles. Graphite crucibles come in a variety of sizes to accommodate different needs and applications. They can range from small crucibles used in jewelry making or small-scale laboratory experiments to larger crucibles used in industrial applications like metal casting or melting. The size of the crucible needed depends on the amount of material to be melted or processed and the specific requirements of the application. Thus, various sizes are available to cater to different needs and ensure efficient and effective use of graphite crucibles.

Q: Is the silicon carbide crucible good for use? What's the difference between an ordinary graphite crucible and a graphite crucible?: Easy to use and convenient.The ordinary graphite crucible can not guarantee the safety in the high temperature environment, moreover, the conduction speed is slow in the test, which is not good for the experiment.

Q: Can graphite crucibles be used for jewelry making?: Certainly, jewelry making can make use of graphite crucibles. Graphite crucibles possess a remarkable melting point, rendering them perfect for the melting and casting of valuable metals like gold, silver, and platinum. Furthermore, they exhibit exceptional resistance to thermal shock and possess commendable thermal conductivity, which promotes efficient and uniform heat dispersion. In addition, graphite crucibles show chemical inertness, ensuring that they do not react with molten metals and thus do not taint the jewelry being produced. Consequently, they have become a favored selection among jewelers and artisans who necessitate a dependable and long-lasting crucible for their jewelry making procedures.

Q: How do you prevent graphite crucibles from cracking due to thermal stress?: There are several measures that can be implemented to prevent graphite crucibles from cracking due to thermal stress: 1. Gradual preheating is important before using a new graphite crucible. This helps eliminate any moisture or volatile components, reducing the risk of thermal shock. 2. To avoid cracking, it is crucial to gradually heat and cool the crucible, preventing rapid and extreme temperature changes. This allows for uniform expansion and contraction, minimizing the risk of cracking. 3. Proper heating techniques must be used, such as applying a uniform heat source. Uneven heating can cause localized expansion and contraction, increasing the chances of cracking. 4. It is important to maintain the recommended temperature range for each type of graphite crucible. Exceeding the temperature limit can lead to thermal stress and eventual cracking. 5. Handle graphite crucibles with care to prevent cracking. Avoid sudden impacts or rough handling that can easily damage them. 6. Regularly inspect crucibles for wear, cracks, or damage. If any issues are identified, replace the crucible immediately to prevent further damage or accidents. By implementing these preventive measures, the risk of thermal stress and cracking in graphite crucibles can be significantly reduced, ensuring their long-lasting performance.

Q: Can graphite crucibles be used for carbon and graphite production?: Certainly! Graphite crucibles have the capability to facilitate carbon and graphite production. Manufactured using high-purity graphite, they are specifically engineered to endure intense temperatures and chemical interactions. With their exceptional thermal conductivity and resistance to thermal shock, these crucibles are exceptionally suitable for carbon and graphite production endeavors. Their versatility allows for utilization in diverse processes, encompassing the melting and refining of carbon and graphite substances. Moreover, graphite crucibles can be employed repeatedly, thus proving to be an economical option for carbon and graphite production.

Q: When decomposing iron ore, why should it be carried out at low temperature?: The commonly used acid decomposition method is as follows:(1) hydrochloric acid decomposition of iron ore can generally be heated by hydrochloric acid decomposition, iron silicate soluble in hydrochloric acid, can add a little hydrofluoric acid or ammonium fluoride, the sample is completely decomposed. The dissolution rate of magnetite is very slow, add a few drops of stannous chloride solution, the decomposition speed is.(2) sulfuric acid hydrofluoric acid decomposition sample, in the platinum crucible and the plastic crucible, adds 1:1 sulfuric acid 10 drops, hydrofluoric acid 4-5ml, the low temperature heats up, when will emit three oxidation two sulfur white smoke, extracts with hydrochloric acid.(3) when sulfuric acid or sulfur phosphorus mixed acid (1:2) dissolves, the ore needs to be heated until the water is completely evaporated, and the white smoke of three sulfur trioxide is added, and then heated for several minutes. But the heating time should not be too long to prevent the formation of pyrophosphate.

Q: How do you prevent overheating of a graphite crucible?: There are several measures that can be taken to prevent overheating of a graphite crucible: 1. Careful temperature control is essential. It is crucial to monitor and regulate the temperature of the furnace or kiln where the graphite crucible is being used. By keeping the temperature within the recommended range, overheating of the crucible can be avoided. 2. Insulating the furnace or kiln adequately can help maintain a stable temperature and prevent excessive heat transfer to the graphite crucible. By using high-quality insulation materials and ensuring proper installation, the risk of overheating can be effectively reduced. 3. It is important to avoid sudden temperature changes, as they can cause thermal shock and lead to cracks or failure of the crucible. Extreme temperature variations should be avoided, especially when the crucible is already hot. 4. Proper handling and storage of graphite crucibles are crucial. They should be handled with care to prevent any damage that could compromise their integrity. When not in use, they should be stored in a dry and cool environment, away from direct sunlight and sources of excessive heat. 5. Regular maintenance is essential. The graphite crucible should be inspected regularly for any signs of wear, cracks, or damage. If any issues are identified, the crucible should be replaced promptly to prevent the risk of overheating and potential accidents. By following these preventive measures, the lifespan of the graphite crucible can be enhanced, and the risk of overheating can be minimized, ensuring optimal performance in various high-temperature applications.

Q: What is the porcelain crucible with a small hole under it?: The crucible can be divided into three categories: graphite crucible, clay crucible and metal crucible. In the graphite crucible, there are three kinds of universal graphite crucible and special graphite crucible and high-purity graphite crucible. Various types of graphite crucibles, because of their performance, application and application conditions, are different in raw materials, production methods, process technology and product models and specifications.

Q: What are the uses of graphite crucibles?: Used in automotive, electronic and new material industries, graphite crucibles are hot containers for melting and containing non-ferrous metals and new materials.
