Abstract

En fremgangsmåte for å drifte en elektromagnetisk støpeanordning for silisium tar i betraktning: målinger av overflatetemperaturen til støpeblokken og temperaturen til varmeovnen; regulering av induksjonsfrekvensen for den elektromagnetiske støpeprosessen; regulering av utgangseffekten for kraftkilden til oppvarmingsanordningen basert på den målte overflatetemperaturen til det størknede silisiumet; og regulering av induksjonsfrekvensen for induksjonskraftkilden basert på den målte induksjonsfrekvensen til kraftkilden til induksjonsspolen; følgelig er det mulig å sikre en bemerkelsesverdig sikkerhet og produktivitet ved kontinuerlig støping av silisiumblokken, og dermed gjøre det mulig å lette produksjon av en polykrystallinsk silisiumhalvlederblokk, som har bred anvendelse for sikker drift.
