Q:What's the pot in the lab that puts in the oven?: The laboratory uses the possibility of a silicon carbide crucible, followed by clay and graphite crucibles, and the 2 are black or black gray. Corundum crucible for red meat or close to white. The inner surface of the cast iron crucible is rough, and the stainless steel crucible is smooth and metallic.

Q:How to cast aluminum parts: After the molten aluminum, the temperature increased to more than 850 degrees, adding silicon powder mixing, heat preservation 40-60min, the temperature of 720-750 degrees into the metal mold can be.

Q:What are the main changes in graphene supercapacitors?: The advent of graphene supercapacitors, the first change is electronic products and digital products, why do you say so? Because the ultracapacitor is obviously charging and discharging faster. So, for example, mobile phone charging, electric cars, electric cars, computers and other products will decline in price. The birth of super capacitors indicates that mobile phones can become thinner and smaller, because the space that the battery takes can be smaller.

Q:Is it possible to achieve a controlled atmosphere inside a graphite crucible?: Yes, it is possible to achieve a controlled atmosphere inside a graphite crucible. Graphite crucibles are commonly used in high-temperature applications such as melting metals and alloys. In order to achieve a controlled atmosphere, various methods can be employed. One method is to use a gas purging system. This involves introducing a specific gas into the crucible to create the desired atmosphere. For example, if an inert atmosphere is required, gases like argon or nitrogen can be used to displace any oxygen or other reactive gases present. The flow rate and pressure of the gas can be controlled to maintain the desired atmosphere. Another method is to create a sealed environment around the crucible. This can be achieved by using a furnace or an induction heating system with a gas-tight enclosure. By controlling the gas composition and pressure within this enclosure, a specific atmosphere can be maintained around the crucible. Additionally, it is important to consider the crucible material itself. Graphite is known for its high thermal conductivity, which means it can transfer heat quickly. However, it can also be reactive with certain gases or metals at high temperatures. Therefore, selecting the appropriate grade of graphite and ensuring proper crucible conditioning can help maintain a controlled atmosphere. Overall, with the right equipment and techniques, it is possible to achieve a controlled atmosphere inside a graphite crucible, allowing for precise control of the environment during high-temperature processes.

Q:Can a graphite crucible be used for silver melting?: Yes, a graphite crucible can be used for silver melting. Graphite crucibles are commonly used in high temperature applications, including melting silver and other metals. Graphite has a high melting point and excellent thermal conductivity, making it ideal for melting and refining silver. Additionally, graphite crucibles have good resistance to thermal shock, meaning they can withstand rapid heating and cooling cycles without cracking or breaking. However, it is important to note that when using a graphite crucible for silver melting, it is crucial to properly prepare and condition the crucible before use to prevent any impurities from contaminating the silver.

Q:What are the different methods of preventing graphite crucible scaling?: There are several methods to prevent graphite crucible scaling. One common method is applying a protective coating on the crucible's surface. This coating acts as a barrier between the crucible and the materials being melted, reducing the chances of scaling. Another method is preheating the crucible before use, which helps to eliminate any moisture or impurities on the surface, preventing scaling. Additionally, using a flux or protective gas during the melting process can help minimize scaling by creating a controlled atmosphere around the crucible. Regular cleaning and maintenance of the crucible, including removing any built-up scale, is also important in preventing scaling.

Q:Can a graphite crucible be used for laser melting applications?: Indeed, laser melting applications do allow the utilization of graphite crucibles. Renowned for their elevated melting point, exceptional thermal conductivity, and resistance to chemical reactions, graphite crucibles prove to be well-suited for high-temperature endeavors such as laser melting. They demonstrate resilience against the formidable heat produced by laser beams and effectively conduct heat to the material being melted, guaranteeing consistent and regulated melting. Furthermore, graphite crucibles are frequently favored for their robustness and long lifespan, rendering them a financially prudent option for laser melting applications.

Q:Can graphite crucibles be used for melting and casting of non-ferrous metals?: Yes, graphite crucibles can be used for melting and casting of non-ferrous metals. Graphite crucibles are widely used in various industries, including foundries and metalworking, for their excellent thermal conductivity and resistance to high temperatures. Non-ferrous metals, such as aluminum, copper, zinc, and gold, have lower melting points compared to iron and steel, making them suitable for melting in graphite crucibles. The high thermal conductivity of graphite helps to evenly distribute heat throughout the crucible, ensuring efficient melting and casting of non-ferrous metals. Additionally, graphite crucibles have good chemical resistance and low reactivity with non-ferrous metals, which further enhances their suitability for this application. However, it is important to note that graphite crucibles may not be suitable for certain reactive or corrosive metals, as they can react with graphite and affect the quality of the casting.

Q:Medium frequency furnace plus graphite crucible does not start: The graphite content of the crucible is too low, the furnace is not tight enough, the quartz sand is not tight between the induction ring and the crucible, and can not start or the electric current is slightly large, and the power is automatically cut off.

Q:Can graphite products be calcined in air for a long time?: Tolerable。One of the main uses of graphite is to produce refractories, including refractory bricks, crucibles, continuous casting powders, mold cores, molds, detergents and high temperature resistant materials. In recent years, two important changes in the refractory industry is MgO-C brick is widely used in steelmaking furnace lining, and the application of aluminum carbon brick in continuous casting process. The graphite refractories and steelmaking refractories are closely linked, the world steel industry about consumption.
