Description
  • Příspěvek se zabývá matematickým a počítačovým modelováním elektromagnetického, teplotního a tlakového pole v roztaveném hliníku v typické kelímkové indukční peci. Úloha se řeší v kvazisdružené formulaci. Po roztavení je kov dále ohříván na teplotu lití, která je typicky asi o 200 °C vyšší než teplota tavení. Poté je výkon induktoru snížen tak, aby se teplota taveniny udržovala v blízkosti uvedené hodnoty. Přitom se tavenina více či intenzivně míchá Lorentzovými silami. (cs)
  • The paper deals with the mathematical and computer modeling of quasi-coupled electromagnetic, temperature and hydrostatic fields in molten aluminum in a typical crucible induction furnace. After the process of melting, the melt is further inductively heated to reach the casting temperature that is typically higher by about 200 oC than the melting point. Then the active power of inductors is reduced to a level making possible only to keep the temperature at that value. During that time, however, more or less intensive stirring of the melt takes place because of presence of the Lorentz forces acting in melt.
