Product Description

 Main products: high purity graphite,Isostatic pressed graphite,  graphite electrode,  flake graphite, , mechanical equipment ,  various processing graphite mould and graphite products.
   
Introduce
The thermal system of a single crystal furnace, known as a thermal field, refers to the whole system in order to melt the silicon and keep the single crystal growing at a certain temperature.

Thermal field generally includes ((graphite materials) pressure ring, insulation cover and 3 insulation cover (three disc crucible), graphite crucible, crucible supporting rod tray, electrode, crucible, heater, guide tube, graphite bolts, and to prevent leakage of silicon, furnace bottom, metal electrodes, supporting rod are set up protection plate, protective sleeve
Advantage
1.High strength    (Flexural strength: 39Mpa  Compressive strength: 78Mpa   With rising of temperature, graphite strength increases)
2.High purity   (Carbon: 99.5%)
3.High temperature resistance (graphite material melting point is 3850±50)
4.good heat shock resistance.
