- Q: Can a graphite crucible be used for melting carbon-based materials?
- Yes, a graphite crucible can be used for melting carbon-based materials. Graphite is an excellent conductor of heat and has a high melting point, making it suitable for high-temperature applications like melting carbon-based materials. Additionally, graphite crucibles have good chemical resistance to withstand the corrosive nature of carbon-based materials during the melting process.
- Q: How to select and use the carbon graphite for machinery? What items should we pay attention to?
- Selection must be based on the working conditions of the equipment, taking into account the pressure, wire speed, medium, and grinding materials and other factors, if necessary, after the test selected appropriate.
- Q: The graphite boat loading and loading real real graphite boat is what?
- Main features:1, can make accurate Shi Mozhou bearing loading vehicle positioning;2 、 made of stainless steel, the structure of the whole machine is firm and reliable;3 、 adopt GK series high efficiency air filter 3;4, PECVD carrier car inside, can tilt 15 degrees or rotate 180 degrees;5 、 purification fan noise is less than 50dB.6, to ensure that the work area to achieve the requirements of cleanliness 100.
- Q: You solved it. What happens if a quartz crucible is coated with a graphite crucible?
- It doesn't work, but it just adds heat resistance. You get a pretty bad heating effect when you put things in. Of course, if you put it very, very tight, the graphite crucible may crack when heated.
- Q: I'd like to smelt 104 aluminium alloy by medium frequency furnace. What should I pay attention to? Please point it out, thank you!
- I can not decide which is good. I just want to talk about the smelting methods of some nonferrous alloys of my own experience. (1) casting, casting, tin bronze, 5-5-5, fused magnesia, medium frequency furnace smelting. Carbon contamination of aluminum alloy and copper alloy
- Q: Can graphite crucibles be used for metal powder sintering?
- Yes, graphite crucibles can be used for metal powder sintering. Graphite crucibles are often preferred for sintering because they have excellent thermal conductivity and can withstand high temperatures. Additionally, graphite crucibles do not react with most metals, making them suitable for sintering various types of metal powders.
- Q: How do you determine the appropriate crucible insulation for a specific application?
- When considering the appropriate crucible insulation for a specific application, several factors come into play. First and foremost, it is crucial to understand the temperature needs of the application. Different materials have different temperature limits, so it is important to choose an insulation material that can withstand the desired temperature range. For high-temperature applications, materials like ceramic fiber or refractory bricks may be suitable, while for lower temperatures, materials like vermiculite or perlite could be used. In addition, the thermal conductivity of the insulation material should be taken into account. Lower thermal conductivity ensures better heat retention and insulation capabilities. Therefore, insulation materials with low thermal conductivity, such as ceramic fiber or refractory bricks, are often preferred for applications where efficient heat retention and control are necessary. The physical properties of the insulation material also play a significant role. Factors like density, compressive strength, and resistance to thermal shock need to be considered. A denser material may provide better insulation, but it could also be heavier and more challenging to handle. Compressive strength is crucial if the crucible will be subjected to pressure or loads. Additionally, resistance to thermal shock is essential if the crucible will undergo rapid temperature changes. Furthermore, it is important to evaluate the compatibility of the insulation material with the substance being processed in the crucible. Some materials may react or corrode when in contact with certain chemicals or metals, which could compromise the integrity of the crucible. Therefore, selecting an insulation material that is chemically inert and resistant to the substances being handled is essential. Lastly, cost and availability should be taken into consideration. Some insulation materials may be more expensive or harder to source than others. Therefore, finding a balance between the desired properties and budgetary constraints is essential. Overall, determining the appropriate crucible insulation for a specific application requires a comprehensive evaluation of temperature requirements, thermal conductivity, physical properties, compatibility, and cost considerations. Seeking advice from experts or conducting thorough research can be beneficial in selecting the most suitable insulation material for a given application.
- Q: Can graphite crucibles be used for plasma arc melting?
- Graphite crucibles prove useful in plasma arc melting as they possess high thermal conductivity and resistance to high temperatures. This makes them suitable for a range of high-temperature applications. Given that plasma arc melting involves the use of an electric arc to create and sustain a plasma state, it necessitates a crucible capable of enduring the intense heat generated throughout the process. Graphite crucibles excel in this regard, as they can withstand these extreme temperatures and serve as a stable and durable container for the resulting molten material. Moreover, graphite crucibles exhibit commendable chemical resistance, enabling them to handle corrosive substances that may arise during plasma arc melting. In summary, graphite crucibles remain a prevalent and effective choice for plasma arc melting applications.
- Q: Can graphite crucibles be used for melting rare earth metals?
- Melting rare earth metals is possible using graphite crucibles. Graphite possesses desirable qualities like a high melting point, excellent thermal conductivity, and resistance to chemical reactions. These properties make graphite an ideal material for applications that involve high temperatures, such as melting rare earth metals. Moreover, graphite crucibles are durable and can endure the harsh conditions associated with molten metals. This makes them a suitable choice for the melting and refining of rare earth metals. Nevertheless, it is crucial to acknowledge that certain rare earth metals, like cerium, can react with graphite when exposed to high temperatures. This can lead to the formation of carbonates. Hence, it is advisable to carefully consider the specific properties and reactivity of each rare earth metal before employing graphite crucibles for the purpose of melting.
- Q: Can quartz ceramic crucibles instead of graphite crucibles?
- Graphite heat resistance is much higher than that of quartz ceramics; graphite can be more than 2000, while the highest resistant quartz ceramics 1700 degrees.
