·High thermal conductivity ensures rapid and even heating
·High strength and crack resistance
·Adopt advanced materials, effectively resist chemical erosion
·Long service life
·Widely used in various fields
Silicon carbide graphite crucibles are industrial products used for high-temperature melting and casting, with excellent heat resistance and chemical corrosion resistance. They remain stable at extreme temperatures and are suitable for melting various metals, including non-ferrous and precious metals.
These crucibles support various furnace types, including resistance furnaces, medium-frequency electric furnaces, electromagnetic induction furnaces, bio-particle furnaces, gas furnaces, coke ovens, and oil furnaces. They are usually used in metallurgy, casting, glass manufacturing, ceramics production, and chemical analysis.
Compared with ordinary crucibles, their service life is three to five times longer, playing a vital role in the efficient and reliable melting and casting of metals.
DECENT silicon carbon graphite crucibles are suitable for a variety of high-temperature applications. Their excellent thermal conductivity ensures uniform heating and reduces energy consumption. High thermal shock resistance minimizes the risk of cracking during rapid temperature changes, while their chemical stability ensures the purity of the molten metal, playing a crucial role in the metallurgical field.
·Made from high-quality materials, the crucibles are dense, uniform, defect-free, and strong.
·Use natural graphite materials and silicon carbide, and isostatically pressed, the crucibles produced have thin walls and excellent thermal conductivity.
·Graphite crucibles have a special glaze layer and dense molding materials, which are highly resistant to chemical attacks that may be caused by flux and additives.
·Able to withstand extremely high temperatures, they can maintain structural integrity even after repeated heating and cooling cycles.
·The formula design fully considers the use process to prevent oxidation of the crucible, making it have a longer service life.
