4) fast delivey
STA graphite crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.
Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and etc.
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.
Some technical parameters :
Maximum Grain Size
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
