Smelting Graphite Crucible  Specifications: (Customized)

Company Introduction ChenganTiantian Carbon Co.,Ltd. is located in Cheng'an County, Handan City, Hebei Province. It covers an area of 6 0, 000 square meters, has a registered capital of 5,000,000,0 RMB and employs 160 people. It is the world's leading graphite electrode manufacturer. 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 encountered working conditions: 1. Purification and smelting in the aluminum industry, using the furnace as an electric furnace, using a temperature of 700-800℃. 2. For aluminum casting, temperature 750-820℃. 3. Fused ceramic material, used in high frequency furnace, temperature 1600℃. 4. Aluminium alloy solution, temperature 2000℃, vacuum environment. 5. High-frequency furnace melting gold, continuous use for 24 hours. 6. Mineral analysis graphite crucible. 7. Vacuum aluminum plating. 8. Smelting precious metal high purity graphite crucible. Bulk density more than the 1.8g/cm. Graphite crucible can be divided into: Pure graphite crucible/ Clay graphite crucible/ Silicon carbide. Pure graphite crucibles generally smelt gold and silver, jewelry and other products requiring higher purity. Clay graphite crucibles and silicon carbide bismuth are widely used in large-scale smelting plants such as copper and aluminum. Pure graphite crucible is widely used in various industries such as non-ferrous metals and precious metals, industrial furnaces, molds, glass, rare earths, photovoltaics, and laboratory analysis. There are various selections of the materials. Based on the working environment, our engineers will offer the suitable graphite material. Packaging & Shipping
