Smelting Graphite Crucible Operating Tips:

1. The graphite crucible should be kept in a dry situation.

2. Take the graphite crucible carefully

3. Warm the graphite crucible in the drying machine or near the furnace. The warming temperature should be up to 500℃.

Graphite Crucible Advantages For Smelting:

1.High strength (Flexural strength: graphite strength increases)

2.High temperature resistance (graphite material melting point is 3850±50C)

3.Good heat shock resistance


5.Strong corrosion resistance to acid and alkali liquid

6.Abrasion resistance,

7.Good conductivity and thermal efficiency.

8.Excellent chemical stability

9.Small thermal expansion coefficient

10.Easy to clean

11. High Purity

12. High machining capabilities

Graphite Crucible  Application:

Graphite crucible with its special character is widely used in the smelting area e.g. gold smelting, silver smelting, aluminum smelting, and copper etc. smelting in metallurgy, casting, machinery, chemical, and other industries.

Graphite crucible with good thermal conductivity and temperature resistance, in the use of high temperature, thermal expansion coefficient, resistance to thermal shock, chilling with a certain strain of performance. Acids, alkaline solutions of strong corrosion resistance, good chemical stability. In metallurgy, casting, machinery, chemical industry and other industrial sectors, are widely used in alloy tool steel smelting and melting of non-ferrous metals and their alloys. And have a better technical and economic effect. a. Thermal stability: We make special design to assure the quality according to the instant temperature changing working condition. b. Corrosion resistance: Precise design extends the ability of corrosion resistance of the crucible. c. Impulsion resistance: graphite crucible can stand very strong heat impulsion, so it can be freely used in any technique process. d. Acid resistance: Impregnation of special stuff can improve the quality of the crucible and it is outstand in the acid resistance. As a result, it can prolong the work life of the graphite crucible.
