1. a kind of manufacturing method of resistance to oxidation carbon product, it is characterised in that:

  • the manufacturer comprising following processing steps and sequenceMethod;

    1) the various solid state components of surface oxidation-resistant reagent treatment are stocked up in proportion, is done with water or other volatile reagents moltenAgent is configured to slurries;

    The solid state component are as follows;

    the compound of silica and aluminium oxide, metal oxide semiconductor, anti-steel slag wear resistanceMetal oxide, improve thermal shock resistance substance, enhance flexural strength substance;

    2) outer surface for the carbon product that slurries are coated or are immersed in after the completion of being graphitized, forms wet surfaces layer;

    3) it takes out, is dried 5-10 days in dustless room temperature environment of divulging information, form the carbon product with dry state superficial layer;

    4)

         3) product obtained in is placed in sintering furnace or closed chamber, uses the highest temperature for 3000 DEG C, lowest temperature isThe high temperature of the melting temperature of the minimum substance of fusing point carries out the sintering of dry state superficial layer in its solid state component, and be sintered be in hydrogen orIt is carried out in the reducing atmosphere of person'"'"'s carbon monoxide, forms the anti-oxidant thin layer of ceramic state on the surface of carbon product;

    5) carbon product for being provided with the anti-oxidant thin layer of ceramic state is directly used as steel-making electrode or electrolysis electrode.
