HEBEI RUBANG CARBON PRODUCTS CO., LTD developed the new technology antioxidant coating and suceed in oct.

The technology of antioxidant coating for graphite electrode, is used on the graphite electrodes of electric-arc furnace steelmaking. it is by novolac epoxy, polyvinyl formal acetal, phosphoric acid, silicon carbide, silicon-dioxide, compositions such as aluminum oxide, ferric oxide, boron nitride, norbide.be a kind of slurries, can with brush, spray, smear or impregnating method primary coating on the electrode surface below the electrode dop, have that adhesive power is big, oxidation-resistance is strong, apply advantage easily, uses graphite electrode consumption to reduce by 0.8-1.0kg on one ton of steel 7-8kg of original every refining basis.0933a after graphite electrode antioxidant process new technology new coating – extended graphite electrode use time 26~70.4%.

In the process of using graphite electrode for electric arc furnace when producing steel, due to the high temperature oxidation environment, the oxidation of the electrode side is about 60% of the total consumption. graphite electrode antioxidants in 600 ~ 1800 ℃ range, can avoid electrode contact with air directly to reduce the surface oxidation of graphite electrode and prolong the life of electrode.

The impregnated products can be used in combination with the coating products, and the anti-oxidation can be greatly improved. the oxidation resistant topcoating under the carbon product high temperature, be applicable to be coated on the graphite electrodes that electric-arc furnace steelmaking uses, play the anti-oxidation protection effect graphite electrode anti-oxidation treatment comparison as below format:

NOTE: The data is the results of anti-oxidation test of graphite electrode on 4 september 2017 from suzhou iron & steel group.
The decrease of power consumption is calculated according to the experimental results of steel mills.
