Graphite Electrodes For Steel Making High Power HP 16 Inch EAF LF HP400

Short Description:

HP graphite electrodes are an essential component of electric arc furnaces, and their choice is critical to the energy efficiency of the furnace operation. High-quality needle coke used in the production of HP graphite electrodes ensures high thermal conductivity, low coefficient of thermal expansion and enables them to withstand the most demanding applications. The application of HP graphite electrodes is widespread in the production of steel alloys, non-ferrous metals, silicon, and phosphorus. HP graphite electrodes are also ideally suited for use in submerged arc furnaces. The choice of HP graphite electrodes is the best option for reliable and long-lasting furnace operation, and this makes them the ideal choice in modern industry.

Surface Quality Ruler

1.The defects or holes should not more than two parts on the graphite electrode surface, and the defects or holes size not be allowed exceed the data in chat below mentioned.

2.There is no transverse crack on the electrode surface.For longitudinal crack,its length should be not more than 5% of the graphite electrode circumference,its width should be within 0.3-1.0mm range.Longitudinal crack data below 0.3mm data should be negligible

3.The width of he rough spot(black) area on the graphite electrode surface should be not less than 1/10 of the graphite electrode circumference,and the length of rough spot(black) area over 1/3 of the graphite electrode length is not be allowed.
