ABSTRACT:
Oven for non-metal melting, in particular silicon melting, with a housing enclosing an interior, at least one mould arranged in the interior for receiving a non-metal melt, at least one electrical heating device enclosing, at least partially, the at least one mould for influencing the temperature of the non-metal melt, and a power supply device connected in an electrically conductive manner to the at least one heating device for providing the heating device with a time-variable current I(t), wherein the current I(t) has a frequency of 0.1 Hz to 1000 Hz and the current I(t) is of a magnitude sufficient for setting a predetermined temperature of the non-metal melt, the currents in the plurality, where necessary, of heaters having a defined phase position in respect of one another.
