Minimum wettability to molten metals    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;      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 jewelryindustry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles accordingto 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 wil 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.     Graphite crucible technical paramermers:

  ATTENTION:   1,Crucible should be placed at a dry place or placed in a wooden frame 2,The crucible tongs should be matched to the shape of crucible to avoid damage crucible 3,The quantity of the feeding should be based on the capacity of the crucible, do not feed too much or too tight, otherwise the crucible may be bursted 4,We should tap the crucible when clean the slag, in order to avoid damage the crucible body  5,The pedestal of crucible placed should put some kelp, carbon powder or asbestos powder, pedestal should be matched to the bottom of the crucible, the crucible placed in the center of furnace.  6,There should be maintained distance between crucible and furnace and the crucible should be fixed firmly by wedge 7,Using an excess oxidizer will reduce the life of the crucible     Recommended Products     Refractory Melting Clay Graphite Crucible
