What is the leaching weight gain rate required for the firing of uhp 300 graphite electrode?

uhp 300 graphite electrode

For the common power uhp 300 graphite electrode roasted joint material, the first immersion weight gain rate is not less than 13%, the second immersion weight gain rate is not less than 8%, and the third immersion weight gain rate is not limited. For high-power and ultra-high-power uhp 300 graphite electrode firing classes, the weight gain rate of the first immersion should not be less than 15%, the weight gain rate of the second immersion should not be less than 10%, and the weight gain rate of the third immersion. Unrestricted.

If the weight gain rate is lower than the specified index, the immersion depth must be checked. If the carbon billet is submerged, it should be re-impregnated after baking. If the bulk density of bakery products is low, the weight gain rate should be higher than the above-mentioned regulations.
