Abstract

Si tratta di un forno a bacino per colata in bassa pressione in cui gli elementi riscaldati che mantengono il metallo a temperatura superiore a quella di solidificazione sono disposti lungo il perimetro del forno, permettendo una maggior compattezza del complesso, un risparmio energetico connesso all'irraggiamento diretto ed una minor lungheza del condotto d'iniezione.It is a basin oven for low pressure casting in which the heated elements that keep the metal at a temperature higher than that of solidification are arranged along the perimeter of the oven, allowing a greater compactness of the complex, an energy saving connected to the radiation direct and a shorter length of the injection pipe.
