Graphite Crucible

 Aluminized graphite crucible in the time of our feeding, can not use  too much effort, can not put a lot of one-time, to prevent the material  and crucible wall collision broke the graphite crucible. 2.  If the use of molten aluminum crucible after a period of time is no  longer used, then the need for aluminum alloy crucible bottom of the  remaining material to clean up, to avoid the next time in the use of the  bottom of the material has been condensed, if the material will lead to  condensation of the crucible ,  This will affect its service life, but if the 24-hour continuous use of  molten aluminum crucible will not only reduce its service life, but  also extend its service life Oh. 3.  In the melting aluminum crucible into the dissolved additives when the  amount must be appropriate, too much solvent will damage the inner wall  of the graphite crucible. 4. Regularly carry out inspection and cleaning of molten aluminum crucible, usually about two months to be carried out once.
[Graphite crucible] the basic characteristics:

Graphite crucible Good thermal stability: for the use of graphite  crucible rapid quenching conditions, 2. Graphite crucible good corrosion  resistance, impact resistance, to ensure product quality and  reliability. 3. Graphite crucible good resistance to strong acid, alkali. 4. Graphite crucible Good thermal conductivity: can greatly shorten the melting time, saving energy. 5. Graphite crucible ash is less than 0.1%, to ensure that precious metals in the smelting is not contaminated. 6.  Features: with good thermal conductivity and high temperature  resistance, in the high temperature process, the thermal expansion  coefficient is small, for acute, quenching with a certain anti-strain  performance. The acid and alkaline solution corrosion resistance is strong, with excellent chemical stability. Gold, silver, platinum and other precious metals and other alloys with  high-purity graphite crucible, high temperature products, good  resistance to oxidation and corrosion, long service life.
The use of graphite crucible: graphite crucible commonly used in  experiments and metal smelting, metallurgy, casting, machinery, chemical  and other industrial sectors, is widely used in alloy tool steel  smelting and melting of non-ferrous metals and their alloys.

Graphite  crucible material using special high-purity, high strength, high  density graphite material; after high-precision CNC machining equipment,  can be processed graphite crucible, graphite casting crucible, graphite  oil tank, pull tube, pull the film, product. Graphite  crucible for precious metal smelting selected special special graphite  materials, graphite crucible products can be more than 2 times the  durability of ordinary materials, longer life, more can withstand more  than 2000 ℃ high temperature.

The use of  graphite crucible is very wide, non-ferrous metal melting are basically  used, such as: gold, silver, copper, aluminum, lead, zinc, etc., and  some steel plants can also use graphite crucible
Graphite  crucible has good thermal conductivity and high temperature resistance,  high temperature in the use of the process, the thermal expansion  coefficient is small, for acute, quenching with a certain anti-strain  performance. The acid and alkaline solution corrosion resistance is strong, with excellent chemical stability. In  the metallurgical, casting, machinery, chemical and other industrial  sectors, is widely used in alloy tool steel smelting and melting of  non-ferrous metals and their alloys. And has a better technical and economic effects.
