    摘要: Moulded articles are produced by heating expandable graphite, in which the expandable graphite is first pre-expanded at 140.degree. to 450.degree. C. until a bulk density of 30 to 500 g/l has been reached, at least 50% by volume of a mould is then filled with the graphite thus pre-expanded, and the expansion of the graphite is then completed in the mould by heating to temperatures in the range from 300.degree. to 700.degree. C.

    摘要: An electric arc furnace, signal processing device, storage medium, machine-readable program code, and method for determining a time for charging (e.g., recharging) an electric arc furnace with material to be melted (e.g., scrap) are provided. The electric arc furnace may include electrode(s) for heating material inside the electric arc furnace by an electric arc. By detecting a signal for determining a phase state of an electric arc root on the side of the material to be melted based on a captured electrode current, by checking whether the signal exceeds a predetermined threshold value for a predetermined minimum duration, and by ensuring that the charging time is reached at the earliest when the signal exceeds the predetermined minimum duration threshold value, a state-oriented charging time for an electric arc furnace can be determined to reduce energy use, resource use, and production time for a production cycle to reach a tap weight.
