Graphite moulds for manual and automatic systems
It is made from low ash, hard calcined grade Electro graphite powders which are selected carefully and mixed with bituminous binders in varying proportions. The mix is then extruded or moulded as per requirement and heated to high temperatures in a furnace. The stock material formed has high porosity around 25%. Since its mechanical strength and abrasion resistance is not adequate, the product is impregnated with resins of unmatched chemical resistance, in vacuum autoclaves depending on duty service. The final material is thus made impervious to liquids and gases.
This process greatly improves all physical properties such as compressive and impact strength, abrasive resistance, bringing down porosity of the brick to minimum. The process through cumbersome has found to be unique in combating any chemical attack of corrosion and abrasion at elevated temperatures.
It has been established that Impervious graphite materials withstand continuously temperatures up to 190°C and such linings have been known to be working for years, trouble free.
| Crushing strength kg/cm sq. | 500 |
|---|---|
| Transverse strength kg/cm sq. | 150 |
| Bulk Density | 1.6 |
