Petroleum Coke Needle Coke UHP Electrode 350mm Corrosion Resistance
350mm UHP Electrode
UHP 350mm graphite electrode is our main product. This product selects high quality petroleum coke, needle coke and so on as raw materials, through forming, roasting, macerating, graphitization and mechanical processing and made, as high quality conductive materials for the arc furnace.
- Product Details
This kind of 350mm UHP Electrode is mainly made of petroleum coke and needle coke, coal tar is used as a binder, and it is processed by calcining, batching, kneading, pressing, roasting, graphitization, and machining. It releases electric energy in the form of electric arc in electric arc steel making to heat and melt the charging material as a conductor.
There is no transverse cracks on the surface, and the width of the black surface area on the surface is less than 1/10 of the electrode circumference, and the length is less than 1/3 of the electrode length. It is suitable for metallurgical furnaces, non-ferrous metals industry, foundry, arc furnace steel making, ceramics Smelting, glass industry, etc.
