Crucible Details
The crucible is a refractory container used to melt and smelt metal liquid or the chemical reaction of substances. Its general shape is like a jar for smashing garlic. It is basically a cylinder with a large top and a small bottom. It can be melted or melted by heating the crucible. Extracting some required substances is also an important tool for chemically reacting some substances through heating.
Refractory materials used in crucible manufacturing include various types of ceramics, such as alumina (aluminum oxide), silicon carbide, graphite, zirconia, and magnesia. These materials maintain their structural integrity at elevated temperatures, making them suitable for containing molten metals, glass, slag, and other high-temperature substances.
1.Thermal Shock Resistance:Refractory materials used in crucibles have good resistance to thermal shock, allowing them to handle rapid temperature changes without cracking or breaking.
2.Mechanical Strength:While refractory materials can be brittle, crucibles are designed with sufficient mechanical strength to handle the weight of their contents and to resist cracking or deformation during use.
3.Chemical Stability:These crucibles are resistant to chemical reactions with the materials they contain, which is crucial when working
1. Metallurgy:Refractory crucibles are commonly used in metallurgical processes such as melting, casting, and alloying of metals like iron, steel, aluminum, copper, and precious metals.
2. Glass Manufacturing:In the glass industry, crucibles are employed to melt and shape glass for various applications, including laboratory glassware, optical components, and artistic glassware.
3. Foundries:Crucibles are vital components in foundries for melting and casting non-ferrous metals like bronze, brass, and other alloys.
4. Ceramics Industry:Refractory crucibles are used for firing ceramics and pottery at high temperatures, ensuring uniform heat distribution and controlled firing cycles.
5. Chemical Processing:In chemical laboratories and industrial settings, refractory crucibles are used for high-temperature reactions, calcination, and other processes involving aggressive chemicals.
Semi-silica brick refers to an aluminum-silicon refractory product with a SiO2 content of greater than 65% and an Al2O3 content of 15% to 30%. They generally use clay containing quartz impurities or native kaolin refractory clay or tailings and pyroph...
The Al2O3 content of anchor bricks is above 55%, and some users require that the alumina content reach 75%, and the load softening temperature of 75% bricks reaches 1550C. However, in actual use, anchor bricks with high aluminum content cannot be enough. The key is Flexibility is the most important t...
