Product Description

We supply high quality graphite electrode. Raw material and process Our graphite electrode choose low ash raw material of high grade petrol coke, needle coke and coal pitch, and processed with machining after calcimine adjuvant, mixing, moulding, roasting , pressure impregnation and graphitizing 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 power Allowable used graphite electrode with current density lower than 17A/cm2, mainly used in ordinary power electric furnace for steel-making, silicon smelting and yellow phosphorus smelting. 2. Graphite electrode with oxidation resistant coating Graphite electrode with oxidation resistant coating has protective layer which can conduct electricity,
