- Q:Cast iron into a casting. What is the state of the matter, change, sublimation?
- In metallurgy, casting, machinery, chemical and other industrial sectors, it is widely used in smelting of alloy tool steel and smelting of nonferrous metals and their alloys. And has better technical and economic results.
- 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:What are the different methods of preventing contamination from graphite particles?
- There are several methods that can be used to prevent contamination from graphite particles. 1. Use of containment systems: One method is to use a containment system, such as an enclosed environment or a glove box, to prevent graphite particles from escaping into the surrounding area. These containment systems can be equipped with air filtration and ventilation systems to remove any graphite particles that may be present in the air. 2. Proper handling and storage: Another method of preventing contamination is to ensure that graphite particles are properly handled and stored. This may involve using sealed containers or bags to store graphite, and using appropriate handling techniques to minimize the release of particles into the environment. 3. Regular cleaning and maintenance: Regular cleaning and maintenance of equipment and surfaces that come into contact with graphite can help prevent contamination. This may involve using specialized cleaning methods, such as wet cleaning or vacuuming, to remove any graphite particles that may be present. 4. Personal protective equipment: Using personal protective equipment, such as gloves, masks, and coveralls, can help prevent contamination from graphite particles. These protective measures can help minimize direct contact with graphite, reducing the risk of contamination. 5. Proper training and education: Providing training and education to personnel who handle graphite can help raise awareness about the risks of contamination and the proper precautions to take. This can include training on proper handling techniques, the use of personal protective equipment, and the importance of regular cleaning and maintenance. By employing these methods, contamination from graphite particles can be effectively prevented, ensuring a safe and clean working environment.
- Q:Is the silicon carbide crucible good for use? What's the difference between an ordinary graphite crucible and a graphite crucible?
- The crucible can be placed on the iron tripod with either positive or oblique directions, and can be placed on the basis of the requirements of the experiment. When the crucible is heated, it cannot be immediately placed on a cold metal table to prevent it from breaking due to rapid cooling. It should not be placed on the wooden table immediately so as not to spoil the table or cause fire. The correct method is to cool the metal on the tripod or to let it cool slowly on the asbestos net. For crucible purposes, see the crucible tongs. The relevant information from the supply of silicon carbide crucible dachengxian Tianjin high silicon carbide crucible crucible factory released using the latest international technology of isostatic pressing method and strict quality assurance inspection system, using advanced refractory raw materials, high-tech formula developed a new generation of high-quality silicon carbide crucible, this product has a large volume density, high temperature resistant, fast heat, acid and alkali resistance, high temperature strength, oxidation resistance and high service life is 3 times that of the clay graphite crucible.
- Q:Are graphite crucibles suitable for melting composite propellants?
- Graphite crucibles are generally not suitable for melting composite propellants. Composite propellants consist of a mixture of oxidizers, fuels, and binders, which can be highly reactive and corrosive. Graphite, although known for its high melting point and resistance to high temperatures, can react with certain components of composite propellants. Graphite crucibles can undergo chemical reactions and erosion when exposed to certain oxidizers, such as ammonium perchlorate, which is commonly used in composite propellants. This can lead to contamination of the propellant and affect its performance. Additionally, the binders used in composite propellants can also react with graphite, leading to degradation and potential failure of the crucible. For melting composite propellants, it is recommended to use crucibles made of materials specifically designed for this purpose, such as ceramic or refractory metal crucibles. These materials have better resistance to the corrosive nature of composite propellants and can withstand the high temperatures involved in the melting process.
- Q:Are graphite crucibles suitable for use in a vacuum environment?
- Yes, graphite crucibles are suitable for use in a vacuum environment. Graphite is a highly stable material that can withstand high temperatures and corrosive environments, making it a popular choice for various industrial applications including vacuum environments. Graphite crucibles have excellent thermal conductivity and resistance to thermal shock, which are important properties for maintaining temperature stability in a vacuum. Additionally, graphite has low outgassing properties, meaning it releases minimal gas or vapor when exposed to a vacuum, further making it suitable for use in such environments. Overall, graphite crucibles are a reliable and effective choice for conducting experiments or processes in a vacuum environment.
- Q:What special attention should be paid to the use of graphite crucible in vacuum induction melting of titanium alloy?
- In the smelting of titanium alloy, because there are a lot of active element Ti in the alloy, it is easy to react with C, N, O and other elements, resulting in the change of alloy composition
- Q:Can graphite crucibles be used for melting pharmaceutical compounds?
- Yes, graphite crucibles can be used for melting pharmaceutical compounds. Graphite is a commonly used material in high-temperature applications, and its high thermal conductivity and resistance to chemical reactions make it suitable for melting various substances, including pharmaceutical compounds.
- Q:Can graphite crucibles be used for heat treatment processes?
- Yes, graphite crucibles can be used for heat treatment processes. Graphite has excellent thermal conductivity and high melting point, making it suitable for withstanding extremely high temperatures required for heat treatment. Additionally, graphite crucibles have good resistance to chemical corrosion, which is important when dealing with reactive or corrosive substances during heat treatment.
- Q:Can graphite products be calcined in air for a long time?
- Because graphite has many excellent properties, it has been widely used in metallurgy, mechanical, electrical, chemical, textile, national defense and other industrial sectors. Refractory material. The graphite product keeps the original chemical properties of flake graphite and has a strong self lubrication performance. The characteristics of graphite powder is of high strength, corrosion resistance and acid resistance of the high temperature of 3000 DEG C and resistance to low temperature of -204 DEG C, and its compressive strength is greater than 800kg/Cm2, and the antioxidant, at 450 degrees Celsius in the air was 1%, rebound rate of 15-50% (density 1.1-1.5). Therefore, graphite products have been widely used in metallurgy, chemical, petrochemical, high energy physics, aerospace, electronics and so on.
