Zhok silicon carbide crucible is suitable for melting such metals
as copper, gold, silver, zinc, aluminium, lead . etc And we have the special crucibles used in melting pure cast iron
which need high temperature. Our sic (silicon carbide) graphite crucible ADVANTAGE : Efficient ,Energy-saving ,Environmental protection .
DurableThe age of the crucible (for intermediate frequency furnace ,
resistor furnace , Gas , oil furnace) guaranteed value typical value The big one and the appropriate use could use one year Melting copper type ≥ 35 days 40-45 days Melting aluminum type ≥ 95 days 120-150 days We insure that could use more than 120-150 times Forming styles (How do we made the crucibles ) Type
Forming styles SIZE NO . FROM 0.5 TO 20 Moulded shape pressing SIZE NO . FROM 25 TO 2500 Isostatic pressing / Isostaticcompaction Our crucibles have received high reputations from users around the
world for their excellence in quality and high cost performance. Sic crucibles are constructed of clay graphite and carbon-bonded silicon carbide and are available in wide variety of shapes and sizes.
Glazes are available for most non-ferrous applications and in high and low temperature varieties. Through the years and countless experiences, our crucible manufacturers
have been developing melting and holding molten light alloys such as
aluminum and copper with characteristics of high flux and oxidation resistance. The wide range of application, gas furnace, oil furnace, electric furnace
and induction furnace of high/low frequency also enables our crucibles to
meet users various operations. SiC Crucibles
