High Power Thermal Plasma Heating (HPTP) in Automatic Casting Uunits-Tomorrows Technology Applied to Today s Casting
1 Introduction Foundrymen throughout the world have always respected a basic operating maxim that is essential for the correct working of our foundries. Weare referring to the recommendation that is often repeated but not always remembered: melt cold, pour hot. When we say melt cold, we are referring to how unnecessary it is, both from the point of view of quality and cost, to heat the molten metal more than is strictly necessary. All overheating involves higher consumption of energy and refractory material, increased oxidation looses and greater metallurgical degradation, as well as increased consumption of inoculants and nodulisers, On the other hand, when they sAld pour hot, the foundrymen of the past regarded as ideal those temperatures that allowed us to ensure correct metallurgical quality of the metal and avoid defects associated with low casting temperatures (cold joints, lack of filling, etc. ).
