... conducting crucibles. Later, Ferranti, Colby, and Kjellin developed induction melting furnaces which made use of nonconducting crucibles. In these designs, electric currents were induced directly into the charge, usually at simple line frequency, or 60 Hz. It should be noted that these early induction...

.... Casting production begins with melting of the metal (left side of Fig. 1 ). Molten metal is then tapped from the melting furnace into a ladle for pouring into the mold cavity, where it is allowed to solidify within the space defined by the sand mold and cores. After it has solidified, the casting...

... from its ore through heat treating. This iron was a very primitive material. The early metal makers could not get their furnaces hot enough to melt the resulting mass that collected at the bottom, but this part-metal, part-furnace residue was able to be hammered, while hot, into useful shapes. In 1200...
