  2. Glass melting furnace - Wikipedia

    en.wikipedia.org/wiki/Glass_melting_furnace

    The maximum melting area of day tanks is 10 m2, and the melting capacity is between 0.4 and 0.8 t/m2 of melting area. The pot furnace is one type of this. The furnace consists of a refractory masonry basin with a depth of 40 to 60 cm (bottom furnace), which is covered with a vault with a diameter of 70 to 80 cm (top furnace).

    en.wikipedia.org/wiki/Induction_furnace

    The advantage of the induction furnace is a clean, energy-efficient and well-controlled melting process, compared to most other means of metal melting. Most modern foundries use this type of furnace, and many iron foundries are replacing cupola furnaces with induction furnaces to melt cast iron, as the former emit much dust and other pollutants ...

    en.wikipedia.org/wiki/Metallurgical_furnace

    Electric arc furnaces (EAFs), which apply current to the metal via electrodes over an electric arc. The Flodin furnace is an early EAF, specially designed to smelt iron from ore through the direct addition of carbon; Electric induction furnaces, which heat the metal through eddy currents, requiring metal mostly free of gangue and corrosion

  6. Electric arc furnace - Wikipedia

    en.wikipedia.org/wiki/Electric_arc_furnace

    An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking.
