Graphite Electrode £® Raw material and process Our graphite electrode choose low ash raw material of high grade petrol coke,needle coke and coal pitch, processed with machining after calcimine adjuvant, mixing, forming,roasting , pressure impregnation and graphitization under 3000oC high temperature.With best characteristic of low resistivity, good conductivity, low ash, equality structure, good oxidative stability and high mechanical strength. £®Product sort Graphite electrode can be divided into ordinary power, high power and ultra high power electrode by electrode quality index. 1. Graphite electrode of ordinary powerGraphite electrode which allowable used current density is lower than 17A/cm2, are mainlyused in ordinary power electric furnace for steel-making, silicon smelting and yellow phosphorus smelting. 2. Graphite electrode with oxidation resistant coatingGraphite electrode with oxidation resistant coating has protective layer which can conduct electricity,heat resistant and anti-oxidation, reduce the electrode consume when steel-making. 3. Graphite electrode of high power Graphite electrode which allowable used current density is lower than 18-25A/cm2, are mainly used in high power arc furnace for steel-making. .Application Steelmaking in electric arc furnace, industrial silicon furnace, phosphorus furnace,the corundum furnace Nearly 30% graphite electrodes in our country are used for exportation, and domestic demand is mainly for steel making in the electric arc furnace (35%), smelting of yellow phosphorus in submerged arc furnace(9%), abrasive (8%) and industrial silicon (5%).Demands of the other industries is small.
