HP Graphite Electrode mainly uses petroleum coke, needle coke as raw material, coal tar as binder, is made after calcination, ingredients, kneading, pressing, roasting, graphitization, machining. It is featured with oxidation resistance, low resistivity, acid and alkali corrosion, high efficiency and energy saving and low loss. HP Graphite Electrode is mainly used for high-power electric arc furnace and ladle furnace to steelmaking. If you are looking for a conductor for steelmaking in arc furnace, HP graphite electrode can be your choice! Contact us for free quotation.
High temperature resistant type: graphite melting point is 3850+50℃, boiling point is 4250℃, even by the ultra high temperature are ignition, weight loss is small, thermal expansion coefficient is smal. Graphite with temperature increase and strengthen the intensity, at 2000℃, the intensity of graphite double.
Conductive, thermal conductivity, the conductivity of graphite nonmetalliferous ore is one hundred times higher than normal. Thermal conductivity than steel, iron,lead and other metal materials. Coefficient of thermal conductivity decreases with temperature rise, and even at high temperature, graphite into insulator.
Lubricity, lubrication performance depends on the size of the graphite flake graphite, flake, the greater the friction coefficient is smaller, the better the performance of lubrication.
Chemical stability: graphite at room temperature with good chemical stability, acid,alkali and corrosion resistance to organic solvent.
Plasticity: graphite good toughness, can become very thin slice.
Thermal shock resistance: graphite when used at room temperature can withstand the severe changes of temperature without damage, temperature mutations, graphite volume change is not big, won’t produce crack.
