Characteristics of graphite crucible

Graphite crucible has good thermal conductivity and high temperature resistance. During high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to rapid heating and cooling. It has strong corrosion resistance to acid and alkaline solutions and excellent chemical stability. In metallurgy, casting, machinery, chemical industry and other industrial sectors, it is widely used for smelting alloy tool steel and non-ferrous metals and their alloys. And has a good technical and economic effect.

Graphite crucible is widely used for smelting alloy tool steel and non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical industry and other industrial sectors because of its excellent performance. And has a good technical and economic effect.
The good chemical stability of graphite crucibles makes graphite crucibles widely used in many fields. As mentioned above, graphite crucibles are often used in metallurgy, machinery and other industrial sectors, which are well used for smelting alloy tools, non-ferrous metals, etc., greatly reducing economic costs. But how can we use the graphite crucible correctly and prolong its service life?

Methods to increase the service life of graphite crucible

The graphite crucible is made of graphite, so we must pay attention to moisture and humidity prevention. We must not keep the graphite crucible in a damp place. At the same time, we should pay attention to handling it gently during transportation, so as to avoid damage due to strong shock. Although the graphite crucible can withstand high temperature and prevent acid and alkali, before using the graphite crucible, it must be baked in a dry place, such as near the furnace, and can be used normally only when the temperature gradually rises. Even if the graphite crucible can withstand rapid heat and cold, it cannot be heated or cooled instantaneously. Finally, when usingGraphite crucibleWhen smelting metal, it is better to reduce the use of combustion supporting agent, so as to prolong the service life of the graphite crucible. In addition, when using the crucible, a certain distance must be left between the crucible and the edge of the furnace, so as to better combustion and heat transfer. It should be said that the crucible is placed in the center of the furnace.
