high quality graphite crucible

The main raw material of graphite crucibles is crystalline natural graphite, which has excellent thermal conductivity and high-temperature resistance, strong corrosiveness to acid and alkali solutions, and good chemical stability. There are various types of graphite crucibles, but their application scope is relatively narrow, allowing for free selection. Based on the above excellent properties, graphite crucibles are widely used in industrial fields such as metallurgy, casting, machinery, and chemistry, and can also be used for the refining and refining of non-ferrous metals and new materials.

 

 

There are some instructions for use. As the bottom of the crucible is very small, when heating, the crucible needs to be placed on a graphite pad or a clay triangle. Direct heating is possible, but immediate cooling after heating is impossible. Take it out with tongs. Do not place it on a cold metal table to avoid cracking due to rapid cooling. During use, it is essential to check for any obvious cracks or other issues, and conduct regular inspections after use.

 

Graphite crucibles have strong corrosion resistance to acid and alkali solutions and high chemical safety. In industries such as metallurgy, forging, machinery, and chemical engineering, graphite crucibles are widely used in the metallurgy of alloy tool steel and the smelting of non-ferrous metals and their alloys.

 

Graphite crucibles have excellent thermal conductivity and high-temperature resistance. They have a small coefficient of thermal expansion during high-temperature applications and a certain degree of emergency resistance to rapid heating and cooling, but the resistance is very small. Caution is needed when using them.

 

 

The specifications of graphite crucibles vary, which is determined by the copper content. Here are some points to note: Graphite crucibles should be protected from moisture and stored in a dry place or wooden box. Before use, it needs to be baked beside a dryer or oven. Only after reaching a certain temperature can it be used. The crucible should be placed on the surface of the furnace mouth to prevent the furnace cover from being worn. Add too much or too tightly to prevent the pot from shrinking. The furnace chamber and crucible clamps should be adapted to the shape of the crucible and should hold the middle part to prevent local force from damaging the crucible. The spacing between the furnace walls should be appropriate, and the crucible should be placed in the middle of the furnace chamber. Excessive combustion AIDS and additives will shorten the service life of the crucible. During use, replacing the crucible once a week can extend its service life and prevent strong corrosive flames from being directly sprayed on the sides and bottom of the crucible. These are matters that require more attention.

 

Based on the above, it can be understood that graphite crucibles have excellent high-temperature resistance, and their role is in the extraction of non-ferrous metals, machinery, chemistry and other fields.
