摘要： The present invention relates to a particulate inoculant for treating liquid cast-iron, comprising, on the one hand, support particles made of a fusible material in the liquid cast-iron, and on the other hand, surface particles made of a material that promotes the germination and the growth of graphite, disposed and distributed in a discontinuous manner at the surface of the support particles, the surface particles presenting a grain size distribution such that their diameter d50 is smaller than or equal to one-tenth of the diameter d50 of the support particles.

摘要： The invention relates to a method for manufacturing a foundry body including the preparation of a granular mixture including a polycondensed resin having modified formaldehyde, optionally incorporating an aromatic or polyaromatic during the synthesis thereof, a hardening agent, a formaldehyde sensor compound, water and optionally at least one resin selected from the group comprising tannins, natural polyphenols, and lignins, placing said granular mixture in contact with the surface of a forming tool, and insufflating a flow of gas at 50° C. to 380° C. into the granular mixture for 1 to 300 seconds, in order to ensure at least partial hardening of said mixture. The invention also relates to a method for manufacturing a molded foundry piece made of metal or a metal alloy, which includes pouring metal into at least one body (mold and/or core) thus produced; and to a foundry piece thus manufactured.

摘要： A method for the production of cast iron starting from pre-reduced iron ore (DRI) with an electric arc furnace includes the steps of preparing a charge of pre-reduced iron ore DRI having a metallization higher than 90% and containing over 2.8% by weight of carbon, wherein at least 80% of the carbon is combined with the iron to form iron carbide Fe3C; charging the charge of pre-reduced iron ore into the electric arc furnace; and melting the DRI charge to form liquid cast iron having at least 80% by weight of actual carbon content deriving from the carbon in the charge of pre-reduced iron ore, the melting step being in a reducing atmosphere and in a melting chamber of the electric arc furnace subjected to a positive internal pressure generated by the gases produced by reduction reactions that develop during melting.

摘要： A method for producing steel in which iron ore is reduced with hydrogen and the resulting intermediate product of reduced iron ore and possibly accompanying substances is subjected to further metallurgical processing; the hydrogen is produced through electrolysis of water; the electrical energy required for the electrolysis is regenerative energy from hydroelectric and/or wind and/or photovoltaic sources or other regenerative forms of energy and the hydrogen and/or the intermediate product is produced regardless of the current demand, whenever enough regeneratively produced electrical energy is available; and unneeded intermediate product is stored until there is demand or it is used so that the regenerative energy that is stored therein is also stored and a method for storing discontinuously produced energy in which the discontinuously produced energy, when it is present or after its production, is conveyed into a process in which a storable intermediate product is produced from a source material and the storable intermediate product is stored until it is required and retrieved for the production of an end product.
