graphite electrode for arc furnaces
Description
1)Raw material: Graphite Electrode raw materials use low sulphur and low ash CPC, coke plant pitch, HP grade graphite electrode add 30% Japan needle coke, UHP grade graphite electrode use 100% Janpan needle coke. Widely used in LF, EAF for steel making industry, Non-ferrous industry, silicon and phosphorus industry.
2)Feature: Our graphite electrodes are with low electric resistance, high density, high anti-oxidation capability, precise machining accuracy, especially with low sulphur and low ash will not give steel second time impurity.
3) Grade: RP, HD,HP,SHP,UHP.
4) Diameters: Φ 150~Φ800mm
5) Length: 1600~3000mm
6)Application: Widely used in arc furnace (EAF, LF for steel making) and electrochemical furnace (for metallurgical and chemical industry)
7)Packing:Wooden cases after Fumigation
8)trail order 20Tons
9) Production capability 10000tpa.
10)Delivery time: 30days after L/C operative
11)Terms of payment: We can allow OA, CAD, LC. DP etc. free payment term.
Please specify the dia and nipple size in your inquiry. (Nipple size including 3TPI, 3TPIL, 4TPI,4TPIL.)
