Wadah Grafit

Proses Pembuatan:

The production of graphite crucibles involves petroleum coke, pitch coke, and coal tar pitch, which function as binders. We mix these components and subject them to milling, pressing, and graphitization to create a blank. Subsequent mechanical processing shapes the product into a crucible.

Artificial Graphite, which doesn’t melt at high temperatures, possesses robust thermal shock resistance. Furthermore, it doesn’t contaminate molten metal and slag or adhere to them, making it the optimal choice for a crucible and boat used in metal melting.

Characteristics of Graphite Crucibles:

Graphite crucible has good thermal conductivity and resistance to high temperature. When subjected to high temperature range, they display a small thermal expansion coefficient and have the specific strain capacity for swift heating and cooling.

Graphite crucible melting point is between 1800 – 3697 °C. These crucibles also possess strong resistance to both acid and alkali solutions, exhibiting remarkable chemical stability. Available in various models and specifications, manufacturers can select the ones that best fit their needs.

Crucially, graphite crucibles don’t react or infiltrate molten metal, ensuring the purity of the molten material.

Applications:

Graphite Crucibles find extensive use in sectors like metallurgy, casting, machinery, and the chemical industry. They are often employed in smelting alloy tool steel and non-ferrous metals and their alloys, delivering substantial economic benefits.

Based on distinct usage requirements, manufacturers can shape graphite crucibles into four types: conical, cylindrical, irregular, and shaped, tailoring to diverse needs.
