Carbon graphite crucible material is made of special high purity, high strength and high density graphite material, which is made by high precision CNC processing equipment.
Graphite crucible china sizes are various, ranging from 250g to 800kg. The most seen ones are 2kg/3kg/4kg/5kg/6kg/10kg graphite crucibles. It is mainly used for melting precious metals, gold, silver, copper, aluminum, and various kinds of moulds.
Melting graphite crucible has high temperature resistance, strong thermal conductivity, special glaze layer and dense molding material, which greatly improves the corrosion resistance of the product and extends its service life. As an experienced graphite crucible factory , our company provide mass purchasing and custom services as needed.
TYPES OF GRAPHITE CRUCIBLE
&#;
Graphite Crucible For Induction Furnaces
Isostatic graphite crucible, because of its high-temperature resistance, fast thermal conductivity, acid and alkali resistance, corrosion resistance, and oxidation resistance, can be used for induction furnace, electric furnace smelting use, can not only save fuel to reduce labor intensity but also prolong the service life of the equipment.
Graphite Foundry Crucible
Graphite foundry crucibles, in the process of high-temperature use, thermal expansion coefficient is small, for rapid heating, rapid cooling has a certain strain resistance, stable chemical properties, strong corrosion-resistance, in metallurgy, casting, machinery, chemical, and other industrial sectors, is widely used in the smelting of alloy tool steel and nonferrous metals and their alloys smelting.
Graphite Foundry Crucible
Graphite crucible is suitable for smelting gold, silver, copper, aluminum, alloys and other non-ferrous metals. It has high refractoriness and can withstand ~ &#; high temperature. With low ash content it can ensure that precious metals in smelting is not polluted.
The company is the world’s best artificial Graphite Block supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
Quartz Graphite Crucible
Quartz crucible, has the advantages of high purity, strong temperature resistance, large size, and high precision, good insulation, energy-saving, stable quality, can be directly heated on the flame. Quartz crucibles, like glassware, are easily broken and should be used with great care.
&#;
Graphite Crucibles Uses
Graphite crucibles are widely used in non-ferrous metals and precious metals, alloy smelting industry, aluminum production industry, optical fiber industry, vacuum aluminum plating industry, graphite crucible induction furnace, analysis and test industry, and graphite thermal field and other industries.
Quality
Graphite crucible has excellent corrosion resistance, impact resistance, to ensure the reliability of product quality.
HOW TO TEMPER A GRAPHITE CRUCIBLE
&#;
Graphite crucible in the production of the main material is graphite, including clay, aggregate and other components. The graphite crucible temperature limit mainly depends on the graphite material, but also is affected by other materials.
The graphite crucible melting point is ±50&#; and the boiling point is &#;. Its strength increases with the temperature. At &#;, graphite strength is doubled. After ultra-high temperature arc burning, its weight loss is very small, thermal expansion coefficient is also very small.
FAQS OF GRAPHITE CRUCIBLE
&#;
Q:
What is the manufacturing process of graphite crucible?
The manufacturing process of graphite crucible can be divided into three kinds: hand molding, rotary molding and press molding. The quality of crucible has an important relationship with the forming method. The forming method determines the structure, density, porosity and mechanical strength of the crucible body.
