sic graphite crucible for melting gold

1 . sic graphite for Aluminum , cooper.etc smelting crucible 2 . Efficient ,Energy-saving ,Environmental protection . etc

Graphite crucible have four different main type .

Item 1 , Pure graphite crucible .

       The carbon content always > 99% . machine by pure artificial graphite material .

Item 2 , Clay graphite crucible . Main raw material always are clay , natural graphite             powder , then making the size by Rotational Molding machine . then baking that .           got the clay graphite crucible

Item 3, Sic graphite crucible otational Molding type . Main raw material is sic , natural           graphite , Al2O3 .etc   then making the size by Rotational Molding machine .                 carbon content from 20% to 50% , sic content 20%-40% . with the Prevent           oxidation coating . density always 1.7-1.85

Item 4 , Sic graphite crucible isostatic pressing type , Main raw material is sic , natural           graphite , Al2O3 .etc carbon content ABOUT 30% , sic content ABOUT 40% . then making the size by isostatic pressing machine . Awalys be Europe or japan brand such as Morgan , MARS ISOMELT, mammut-wetro,Foseco , Vesuvius. etc. with high quality . same sic graphite     crucible . The best quality crucible made by this way . Density always 1.95-2.2 .

Item 1 is different to 234 . there are no same place . they are different crucible , different using .

If FOR metling copper, gold ,silver, zinc, aluminium , lead , cast iron .etc Always using 2 .3 . 4 crucible.

Between 2 .3..4  With the standard of using life of India morgan crucible (about melting copper more than 200-250 times )

Item 2 Clay graphite crucible The cheapest and the lowest qualiy . the life is always 1/20 to 1/15 of india morgan crucible

Item 3 Sic graphite crucible otational Molding type Middle quality , middle price . the life is always 1/5 to 1/3 of india morgan crucible

item 4 . Sic graphite crucible isostatic pressing type The most expensive , the best quality ! A little better than india morgan crucible

SIZE NO . = Melting Capacity of copper in KGS

The CRUCIBLE is suitable for melting such metals as copper, gold ,silver, zinc, aluminium , lead , cast iron .etc

And we have the special crucibles used in melting pure cast iron which need high temperature .

Packing : In wooden case for export , Barrel , Carton OR straw rope

ADVANTAGE : Efficient ,Energy-saving ,Environmental protection . Durable

We provide Item 1 . 3 . 4 crucible except Item 2 .
