Graphite crucible formed from natural graphite

The main raw material of graphite crucible is crystalline natural graphite, which maintains the original physical and chemical properties of natural graphite. In addition, graphite has strong acid and alkali corrosion resistance and good chemical stability. The high-quality domestic crucible has the following characteristics:


1. The high density of the graphite crucible makes the crucible have the best thermal conductivity, and the thermal conductivity of the crucible is significantly better than other imported crucibles;


2. The surface of the graphite crucible has a special glaze layer and dense modeling materials, which greatly improves the corrosion resistance of the product and extends the service life;


3. The graphite composition in the graphite crucible is all natural graphite with very good thermal conductivity. After the graphite crucible is heated, it should not be placed on the cold metal table immediately to avoid rapid cooling and cracking.

Graphite crucible has good thermal conductivity and high temperature resistance. In the process of high temperature use, the coefficient of thermal expansion is small, and it has a certain strain resistance to rapid heat and cold. It has strong corrosion resistance to acid and alkaline solutions, and has excellent Chemical stability. Because of the above excellent performance, the production technology level of domestic graphite crucible has reached or even exceeded that of imported crucibles. In metallurgy, casting, machinery, chemical and other industrial sectors, it is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys. , Has good technical and economic effects.
