Clay graphite crucible characteristic :
1. Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we will specially design the production procedure, so as to ensure the reliability of product quality.
2. Corrosion resistance: Even and fine basic design will delay the erosion of crucible.
3. Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out.
4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially its index of acid resistance., and will prolong the service life of graphite crucible.
5. High heat Conduction: High content of fixed carbon ensures the good heat conduction, shorten the time of dissolution, and remarkably reduce the energy consumption.
6. Control of metal pollution: The component of material under strict control will ensure that graphite crucible will not pollute the metals when dissolving.
7. Quality stability: The process technology of forming under high pressure and quality guarantee system will fully ensure the stability of quality.
8 .Using in high temperature process, thermal expansion coefficient is small ,it has resistance strain performance to hot and cold, Strong corrosion resistance to the acid, alkali solution;
Clay graphite crucible features:
a)Excellent Thermal Shock Characteristics
b)Corrosion Resistance
c)As Cast Tight Dimensional Tolerances
d)High Creep Resistance
e)Superior Wear Resistance
f)High strength, extreme hardness,wear resistance, high temperature tolerance, corrosion resistance, oxidation resistance,thermal shock resistance, high thermal conductivity, low coefficient of thermal expansion, creep resistance under high temperature and so on.
Clay graphite crucible advantages:
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.
e. Fine thermal conductivity: High content of fixed carbon ensures the good thermal conductivity, shorten the dissolving time and lower the cost of the oil and other energy obviously.
f. Control of metallic pollution: Strict control of the contents assures that there is no pollution to the metal during dissolving.
g. Quality stability: High-pressure manufacturing method and quality control system can pledge the quality stability better.
Clay graphite crucible applications:
1. Graphite crucible can be used for non-ferrous metal smelting and casting, dissolving gold or silver ornaments, analysis of special type steel, sintering hard metal.
2. graphite crucible for smelting gold is specialized in melting gold in headgear and jewelry industry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles according to customer's requirement.
3. Machined from high pure graphite and widely used in the gold,silver,platinum and other noble metal's melting.If it's used in oxygen atmosphere,it will start to be oxygenized when the temperature is higher than 700-800°c. If it's used in the protective atmosphere, it can stand more than 2000°c.
4. widely used in such fields as industrial furnaces, mono-crystalline silicon machinery, mono-crystalline silicon machinery, electron, semi-conductor, metallurgy, oil, chemistry, textile, electrical machinery, electrical equipment, electrical furnace, traffic, communication industry, medicine, etc.
Four types .
