- Q:Intermediate frequency induction furnace melting copper with what dry pot?
- Graphite crucible, because copper is non-magnetic metal, so the circuit needs to be heated by the crucible, and then the heat of the crucible will melt the copper metal
- Q:How do you prevent graphite crucibles from erosion during use?
- Graphite crucibles can be prevented from erosion during use by following a few key measures: 1. Proper Preconditioning: Before using a new graphite crucible, it is important to precondition it by gradually heating it to high temperatures and gradually cooling it down. This process helps to remove any impurities from the surface and increases its resistance to erosion. 2. Appropriate Handling: Graphite crucibles should be handled with care to avoid any physical damage that could lead to erosion. Avoid dropping or banging them against hard surfaces, and use proper tools when handling them. 3. Controlled Heating and Cooling: Rapid and extreme temperature changes can cause thermal shock and accelerate erosion. It is essential to heat and cool the crucible gradually and uniformly, avoiding sudden temperature fluctuations. 4. Proper Flux Selection: The type and quality of flux used can greatly influence crucible erosion. It is important to select a flux that is compatible with graphite and has a low corrosive effect. Regularly checking and maintaining the flux composition is essential to prevent erosion. 5. Regular Cleaning and Maintenance: After each use, graphite crucibles should be thoroughly cleaned to remove any residue or impurities that could cause erosion. Using appropriate cleaning techniques and materials is crucial to prevent scratching or damaging the crucible. 6. Avoiding Contamination: Contamination from foreign materials can also contribute to erosion. It is important to ensure that only appropriate materials are used in the crucible, and that no foreign substances come into contact with it during use. By implementing these preventive measures, one can significantly reduce erosion and extend the lifespan of graphite crucibles, ensuring their optimal performance and cost-effectiveness.
- Q:Are graphite crucibles suitable for melting magnetic materials?
- No, graphite crucibles are not suitable for melting magnetic materials. Graphite is a non-magnetic material and has a low melting point, making it unsuitable for use with magnetic materials that typically require higher temperatures for melting. Additionally, graphite can react with certain magnetic materials, leading to contamination and impurities in the molten metal. To melt magnetic materials, it is recommended to use crucibles made from materials that are resistant to high temperatures and have low reactivity with the specific magnetic material being melted.
- Q:What is the white product in the crucible?
- What is the white product in the crucible?
- Q:How do you determine the appropriate crucible capacity for a specific application?
- To determine the appropriate crucible capacity for a specific application, several factors need to be considered. These include the amount of material to be melted or processed, the desired temperature range, the duration of the process, and any necessary safety precautions. By evaluating these factors, one can calculate the required crucible capacity that will meet the application's needs efficiently and effectively.
- Q:Can a graphite crucible be used for gold melting?
- Yes, a graphite crucible can be used for gold melting. Graphite crucibles have high melting points and excellent heat resistance, making them suitable for melting and containing gold during the refining process.
- Q:Can quartz ceramic crucibles instead of graphite crucibles?
- For the time being, I don't know what to replace. Since graphite was chosen, nothing else could be used.
- Q:What are the common defects found in graphite crucibles?
- Common defects found in graphite crucibles include cracks, chips, erosion, and oxidation. These defects can occur due to thermal shock, mechanical stress, chemical reactions, or prolonged use at high temperatures.
- 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:Can a graphite crucible be used for melting thorium?
- No, a graphite crucible cannot be used for melting thorium. Thorium has a high melting point, and its reactivity with graphite can cause contamination and reaction with the crucible material. A suitable crucible made from materials like ceramic or refractory metals should be used for melting thorium.
