Other refractory materials for High temperature industry
- 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?
- The filter is not added in the casting process, some slag ran in, leading to the casting surface or internal slag, leakage or air pressure testing, due to impurities, argon arc welding welding is up to where there is always staying, not fusion. The solution, first of all to choose high purity aluminum ingots, some rural plant products do not choose, are turning or cutting scrap materials in investment, not too many impurities; secondly in the casting process, increase to two times to minimize the filtering impurities.
- Q: What graphite crucible is used to smelt aluminium by electromagnetic induction heating?
- You buy that is very cheap graphite crucible, graphite crucible is magnetic good, Wuxi branch cast professional supply excellent magnetic crucible, graphite crucible, we can according to the customer, provide excellent technology of graphite crucible,
- 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: What material can be used to build a furnace for intermediate frequency melting of aluminium bronze?
- Hello, it seems that your smelting furnace is not big. In general, the furnace is melted by the medium frequency smelting furnace. You can only melt two of a small pot.
- Q: Are graphite crucibles suitable for melting composite propellants?
- Yes, graphite crucibles are suitable for melting composite propellants. Graphite is known for its high melting point, excellent thermal conductivity, and resistance to chemical reactions, making it an ideal material for containing and heating composite propellants during the melting process.
- Q: Can graphite crucibles be used for alloy preparation?
- Yes, graphite crucibles can be used for alloy preparation. Graphite is a suitable material for crucibles due to its high melting point, excellent thermal conductivity, and chemical inertness. It can withstand high temperatures and is commonly used in metallurgical processes for smelting and alloying different metals.
- Q: Can a graphite crucible be used for melting berkelium?
- No, a graphite crucible cannot be used for melting berkelium.
- Q: Can a graphite crucible be used for non-ferrous metals?
- Indeed, non-ferrous metals can absolutely be melted using a graphite crucible. Foundries and laboratories frequently utilize graphite crucibles for the purpose of melting and casting non-ferrous metals like gold, silver, copper, aluminum, and zinc. The reason graphite is widely favored for high-temperature applications is due to its exceptional thermal conductivity and high melting point. It possesses the ability to withstand the extreme heat required to melt non-ferrous metals, all the while avoiding any possibility of melting or chemically reacting with the molten metal. Furthermore, graphite crucibles exhibit impressive resistance to thermal shock and are relatively manageable and easy to clean. As a result, they are the preferred choice in various industries when it comes to melting non-ferrous metals.
- Q: What are the uses of graphite? What are the downstream products of graphite?
- Conductive material: used as an electrode and an electric brush in the electrical industry,...
- Q: Are there any special precautions to be taken while using graphite crucibles?
- Yes, there are a few special precautions to be taken while using graphite crucibles. Firstly, it is important to handle them with care as they can be brittle and prone to cracking. It is advisable to avoid sharp impacts or sudden temperature changes to prevent damage. Additionally, graphite crucibles can release small amounts of graphite dust, so it is recommended to wear protective gloves and a mask while handling them to avoid inhalation. Lastly, it is crucial to clean the crucibles properly after each use to remove any impurities or residues that may affect future experiments or reactions.
