Q: How does the hardness of graphite affect the performance of a crucible?: The hardness of graphite plays a crucial role in the performance of a crucible. A harder graphite crucible tends to have greater durability and resistance to wear and tear, resulting in a longer lifespan. Additionally, its higher hardness allows it to withstand higher temperatures without deforming or cracking, making it more suitable for use in high-temperature applications. So, the hardness of graphite directly impacts the performance and reliability of a crucible.

Q: How to extract gold from activated carbon filter?: Depends on the gold in your filter is what state, the ionic state can be used acid and other analytical solution, and then reducing agent or thiourea reduction of gold, simple gold can be replaced by Wang Shuirong, but the impurities will be more.

Q: Can graphite crucibles be used for electrode production?: Indeed, electrode production can utilize graphite crucibles. Graphite, being endowed with a high melting point, commendable electrical conductivity, and chemical stability, proves to be an exceptional substance for electrode fabrication. Industries like metallurgy, foundries, and electrical engineering often employ graphite crucibles when creating diverse kinds of electrodes. These crucibles possess the capability to endure extreme temperatures, thereby creating a steadfast atmosphere for electrode production. Moreover, graphite crucibles possess the advantage of easy customization and shaping to cater to specific electrode necessities, rendering them a favored option in numerous applications.

Q: Can graphite crucibles be used for electron beam melting processes?: Graphite crucibles are indeed capable of being used in electron beam melting processes. They possess exceptional thermal conductivity, a high melting point, and commendable resistance to chemical attack, rendering them appropriate for high-temperature applications like electron beam melting. The remarkable thermal conductivity of graphite aids in the effective transfer of heat, thereby enabling uniform heating and melting of the material. Moreover, graphite crucibles exhibit excellent dimensional stability, a vital factor in ensuring precise control over the melting process. Consequently, graphite crucibles are widely favored in electron beam melting processes due to their advantageous attributes.

Q: Can graphite crucibles be used for melting nickel?: Yes, graphite crucibles can be used for melting nickel. Graphite crucibles are commonly used in high-temperature applications, including the melting of various metals and alloys. Graphite has excellent thermal conductivity and can withstand high temperatures, making it suitable for melting nickel, which has a melting point of around 1,455 degrees Celsius (2,651 degrees Fahrenheit). Additionally, graphite crucibles have good chemical resistance and do not react with nickel, allowing for a clean and efficient melting process.

Q: What are the common uses of graphite?: As a conductive material of graphite in the electrical industry widely used as electrode, brush, carbon, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating etc.. The most widely application of graphite electrode in smelting, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as furnace head conducting material.

Q: Aluminum graphite crucible for iron crucible which is good: The graphite crucible produced by our factory can live for 6-9 months.

Q: How does the electrical resistivity of graphite affect the performance of a crucible?: The electrical resistivity of graphite affects the performance of a crucible by influencing its ability to conduct heat. Graphite has low electrical resistivity, which allows it to efficiently transfer heat to the substance being melted or heated in the crucible. This results in faster and more uniform heating, which is beneficial for various high-temperature applications such as melting metals or glass. Additionally, low electrical resistivity helps to prevent the buildup of excessive heat within the crucible, reducing the risk of thermal stress or damage.

Q: Can graphite products be calcined in air for a long time?: Graphite products are characterized by high thermal conductivity, and stable performance at high temperatures, in the use of the process, even if the temperature is very high, still able to maintain good performance. Graphite crucible thermal expansion coefficient is very small, in the cold, hot situation is still very little impact on the performance of the crucibleGraphite crucible is superior in smelting, alloy, tool steel, non-ferrous metals and other alloy smelting has good advantages, so it is widely used in metallurgy, casting, machinery, chemical and other industrial sectors. The application of the graphite crucible has a good effect both technically and economically.

Q: How does the shape of a graphite crucible affect the melting process?: The melting process can be significantly affected by the shape of a graphite crucible. Graphite crucibles are commonly utilized in high-temperature scenarios, such as melting metals, alloys, and other materials. The efficiency and effectiveness of the melting process are determined by the shape of the crucible. To begin with, the heating and cooling rates of the material being melted are influenced by the crucible's shape. A wider and flatter crucible will expose a larger surface area to the heat source, resulting in faster and more uniform heating. This can lead to a quicker melting process and better distribution of heat throughout the material. Conversely, a narrower and taller crucible will have less surface area exposed to the heat, causing slower and less uniform heating. Furthermore, the shape of the crucible can impact the convection currents within the molten material. Convection currents refer to the flow of liquid or gas caused by temperature differences. A wide and shallow crucible encourages the movement of the molten material, facilitating better mixing and homogenization. This is particularly crucial when melting alloys or materials with varying melting points. Conversely, a narrow and deep crucible may hinder the movement of the molten material, resulting in less effective mixing and potential stratification. Moreover, the shape of the crucible also affects its ability to withstand thermal expansion and contraction. During the melting process, the crucible is subjected to extreme temperatures, which can cause it to expand and contract. A crucible with a shape that allows for even and controlled expansion and contraction is less prone to cracking or breaking under thermal stress. In conclusion, the shape of a graphite crucible plays a vital role in the melting process. A well-designed crucible shape can facilitate faster and more uniform heating, improve mixing and homogenization, and enhance the crucible's durability against thermal stress. Therefore, selecting the appropriate crucible shape is crucial for achieving optimal melting results.
