- 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 official must before casting of aluminum liquid refining slag and gas, because the melting use graphite crucible furnace or silicon carbide crucible furnace refining, so do not suggest that the addition of a solvent in order to avoid corrosion of crucible, the best refining slag degassing process is the use of rotary degassing machine by introducing inert gas such as nitrogen and argon (the best), impurity and hydrogen in liquid aluminum removal, complete slag removal and gas to test the effect of slag by K model, and use the detection instrument for measuring hydrogen hydrogen content, to meet the requirements after the investment casting used.
- Q: What is the aluminum crucible?
- The crucible of aluminium melting can be sintered by neutral sand in medium frequency electric furnace. Melting crucible is made. The service life is more than 300
- Q: Can a graphite crucible be used for gold or silver melting?
- Yes, a graphite crucible can be used for gold or silver melting. Graphite crucibles have high thermal conductivity, which allows for efficient heat transfer during melting. Additionally, graphite has a high melting point and is chemically resistant, making it suitable for withstanding the high temperatures and corrosive environments associated with gold and silver melting. Graphite crucibles are commonly used in various industrial applications, including metallurgy, jewelry making, and dental laboratories, for melting and casting precious metals like gold and silver.
- Q: Can graphite crucibles be used for crystal growth?
- Yes, graphite crucibles can be used for crystal growth. Graphite crucibles are known for their high melting point, chemical resistance, and low reactivity with most substances. These properties make them suitable for creating an environment conducive to crystal growth by maintaining stable temperatures and protecting the crystals from contamination. Additionally, graphite crucibles are often preferred for their durability and ability to withstand thermal shock, making them a popular choice for crystal growth applications.
- Q: Are graphite crucibles suitable for melting alloys with low melting points?
- Yes, graphite crucibles are suitable for melting alloys with low melting points. Graphite has a high melting point and excellent thermal conductivity, allowing it to withstand high temperatures and efficiently transfer heat to the alloy. Additionally, graphite is chemically inert and does not react with most metals, making it an ideal choice for melting low melting point alloys.
- Q: How does the purity of the graphite affect the melting process in a crucible?
- The purity of the graphite in a crucible can significantly impact the melting process. Higher purity graphite has a lower impurity content, which reduces the likelihood of contaminating the molten material. This allows for a more controlled and uniform melting process, as impurities can interfere with the melting temperature and the desired properties of the molten material. Additionally, higher purity graphite has better thermal conductivity, enabling more efficient heat transfer and faster melting. Overall, the higher the purity of the graphite, the smoother and more reliable the melting process in a crucible.
- Q: Graphite producer / graphite manufacturer / graphite enterprise brand, where is there?
- Huixian jade deep graphite mold factory is located in Foshan, Guangdong Province Nanhai Luo Village Industrial Zone, convenient transportation, covers an area of 2500 square meters. With advanced mechanical equipment and many years of experience in the development of engineers, the Pearl River Delta region is a large graphite mold processing enterprises, the main products are:1 kinds of high purity graphite mold, metal continuous casting graphite mould, sealing ring for chemical mechanical, geological drill bit sintering mold, graphite heating element, aluminum stopper and a stirring rod and a bowl bottom base, pouring pipe, launder jacket, graphite ring, roller, lath, Shi Mogan, Guo, graphite electrode, graphite plate graphite precision device.2, diamond products, mold, saw blade mold, drill bit mold, roller mold, grinding wheel, crucible and all kinds of special-shaped mold.3, distribution of various high-quality high purity graphite materials and special graphite G4 material, EDM, continuous casting materials, square material, round material, graphite powder.
- Q: Is it possible to cast or mold materials using a graphite crucible?
- Yes, it is possible to cast or mold materials using a graphite crucible. Graphite crucibles are widely used in various industries, including foundries, jewelry making, and metal casting. Graphite has high thermal conductivity and can withstand high temperatures, making it an ideal material for melting and casting processes. It is commonly used for melting metals, alloys, and other materials that require high heat resistance. The graphite crucible provides a controlled environment for the molten material, ensuring efficient and precise casting or molding.
- Q: Is the yellow metal in the graphite rock gold?
- It would be more convenient if we could find the touchstone. From the proportion can be simply measured, the proportion of gold is very large.
- Q: How do you see the conch alive?
- Slightly touched conch soft tissue, it will be sensitive to contraction, the more sensitive, the more fresh, but not fresh or dead
