Bottom price Graphite Electrode Hp 150mm T3l - HP Graphite Electrode for Steel Making – MORKIN
Bottom price Graphite Electrode Hp 150mm T3l - HP Graphite Electrode for Steel Making – MORKIN Detail:
The Introduction of HP Graphite Electrode
High power graphite electrode is produced by low-sulfur content petroleum coke (or needle coke) as raw materials and coal asphalt as binder through calcination, crushing, batching, kneading, molding, baking, impregnation, rebaking, graphitization and machining. Its physical and mechanical properties are higher than regular power graphite electrode, such as low resistivity and large current density.
The Application of HP Graphite Electrode
(1) For steel smelting in electric arc furnace/ladle furnace
(2) HP Graphite electrode is mainly used in Electric arc furnace for steel making. When graphite electrode is working in EAF, the current will be introduced by graphite electrode into the furnace, and there will be heat source which is generated by electric arc between electrode end and furnace charge for smelting.
(3)For corundum smelting in electric furnace
(4)Used for processing special-shaped graphite products
The blank of graphite electrode is also used to process various special-shaped graphite prod and graphite crucible,etc..
