Types and application fields of best graphite electrode nipples

best graphite electrode nipples are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are made in the form of electric arc in an electric arc furnace. The conductors that release electric energy to heat and melt the charge can be classified into ordinary power, high power and ultra-high power according to their quality indicators.

(1) Ordinary power best graphite electrode nipples: It is allowed to use best graphite electrode nipples with a current density of less than 17A/cm2, which are mainly used in ordinary power electric furnaces for steelmaking, silicon making, and yellow phosphorus making.

(2) Anti-oxidation coating graphite electrode nipples: best graphite electrode nipples coated with an anti-oxidation protective layer to form a protective layer that is both conductive and resistant to high temperature oxidation, reducing electrode consumption during steelmaking.

(3) High-power graphite electrode nipples: The best graphite electrode nipples with a current density of 18-25A/cm2 are allowed, and they are mainly used in high-power electric arc furnaces for steelmaking.

(4) Ultra-high power best graphite electrode nipples: Allow the use of best graphite electrode nipples with a current density greater than 25A/cm 2. Mainly used for ultra-high power steelmaking electric arc furnace.
