Problems solved by technology

However, the applicant found that: the resistivity of these existing conductive materials is high, so that the conductivity is low, the energy consumption is high, the calorific value is large, and the service life is greatly shortened; while graphene has excellent electrical properties, but If it is directly put into the melting furnace, it will be burned or float on the surface of the metal liquid, and it cannot be integrated into the smelting metal, and it cannot be fused with the molten metal at all.
