HP Graphite Electrodes For Electric Arc Furnace & Ladle Furnace Dia. 200-400mm (Inch 10″- 16″)
Overview
The high power HP Graphite Electrode is made of high quality petroleum coke and pitch coke, through the process of raw materials calcining, crushing and grinding, batching, mixing and kneading, molding, baking, impregnation, graphitization, machining, etc. The Graphite Electrode Nipples are made of 100% imported needle coke with three times impregnation and four times baking process. The product has the characteristics of low resistance, good electrical conductivity and chemical stability. It can meet the requirement of various high power electric arc furnaces and ladle refining furnaces for steel making.
Features
- Higher purity, higher density and great chemical stability
- Low coefficient of thermal expansion, resistance to cracking, broken and thermal shock
- Higher mechanical strength and lower electrical resistivity; Higher machining accuracy and good surface
- The advanced antioxidant treatment process, low consumption, and long using life
Applications
- For high power Ladle furnace
● For high power Electric arc furnace steel making
● For Yellow phosphorus furnace
● Apply to Industrial silicon furnace or melting copper.
● Apply to Refine steel in ladle furnaces and in other smelting processes

Products Transportation and Installation Introductions:
(1)The Electrodes should be kept in a clean, drying place and avoid vibrations and collisions. It should be dried before use.
(2) When installing the joint, please clean the hole with the compressed air, then carefully screw the joint and not damage the thread.
(3)When connecting electrodes, the two electrodes should be cleaned with compressed air when they are 20-30mm apart.
(4)When using a wrench to connect the electrode, it should be completely taut to the specified position so that the gap between the two electrodes is not less than 0.05mm
(5)To avoid the electrode fracture, please avoid the insulation block.
(6)To avoid the electrode fracture, please place the bulk block in the upper part.
