WH Graphite high density graphite rod uses graphite block as raw material. After the processing of professional lathe equipment, it is made of different diameters and lengths. The graphite rod current density is a very important parameter, and you can contact us for more information. High density graphite rod is often used in silicon carbide furnace, graphitization furnace and other metallurgical furnace, resistance furnace as furnace lining and conductive material, as well as impermeable graphite heat exchanger.
Graphite rod electrode has good thermal conductivity and high temperature resistance, low thermal expansion coefficient during high temperature use, and has certain strain resistance to rapid heating and cooling.
It has strong resistance to acid and alkali solution corrosion, excellent chemical stability, high temperature resistance, oxidation resistance, corrosion resistance, long service life and other characteristics.
The graphite rod electrode must be kept dry, and must be dried when damp before it can be used.
The compressed air pressure is maintained at 0.5-1.6mpa.
When graphite rod electrode is used, it must be operated according to the working current.
When used for DC power supply, the graphite rod is connected to the positive pole of power supply, and the working pole is connected to the negative pole.
The arc distance between the graphite rod electrode and the workpiece is about 3mm, and the graphite rod exposed fixture is about 100mm.
