Graphite Block
Graphite blocks have a high density, high compressive and flexural strength, low porosity, resistance to erosion, acid and other features. Graphite blocks are widely used as lining materials for metallurgical furnaces and resistance furnaces, and are widely used to process graphite moulds and graphite shaped pieces. Graphite Blocks are also widely used to manufacture glass, chemical and electronics.
The graphite block include molded, extruded, vibrated and isostatic. Our main and most preponderant graphite block is extruded formed.
Advantages
1) Easier for the machining
2) Strong thermal shock resistance ability
3) Not easy to bend compared with copper due to low thermal expansion
4) Fine grain size,good lubrication
5) High melting point,high temperature resistance,high anti-deformation ability

Our company
Hengtai Group, one of the leading enterprises in China Carbon Industry, has been specializing in technology research and development, manufacturing and sales of graphite electrodes, carbon additive and other carbon products. Graphite electrodes are widely used in electric arc furnace and ladle furnace for steel production, ferroalloy production, silicon metal production and smelting processes. In addition to high temperature which can reach up to 3000ºC, our products are featured with higher electrical conductivity, stronger thermal shock resistance, higher mechanical strength, best chemical stability, higher oxidation resistance and lower consumption.
Hengtai Group has built the perfect carbon production processes including calcining, forming, baking, impregnation, graphitization and machining and also has advanced inspection and testing facilities and techniques. Our group has 24-pot calcinator, 3500 MT vacuumized oil hydraulic extrusion forming machine, 18-chamber ring baking furnace, high-pressure impregnation system, full CNC machine line and the first-class carbon inspection equipment.
