Claims (9)
1. Induktionsvarmespole til smeltning af granulat af halvledermateriale på en tallerken med et udløbsrør, omfattende en med strømførespalte forsynet spole med en overside og en underside og med en gennemstrømningsåbning til granulat i et område liggende uden for spolens midtpunkt og strømførende segmenter, som fremstår i midtpunktet af spolens underside, og som via et forbindelsesstykke er elektrisk ledende forbundet på en nedre ende.
2. Induktionsvarmespole ifølge krav 1, kendetegnet ved, at i det mindste én af strømførespalterne er udvidet for at danne gennemstrømningsåbningen.
3. Induktionsvarmespole ifølge krav 1 eller krav 2, kendetegnet ved, at segmenterne danner en form som en keglestub.
4. Induktionsvarmespole ifølge et af kravene 1 til 3, kendetegnet ved, at hældningsvinklen på de strømførende segmenters udvendige flade og hældningsvinklen for udløbsrørets indvendige flade erens.
5. Induktionsvarmespole ifølge et af kravene 1 til 4, kendetegnet ved et kølesystem til køling af spolen og segmenterne,
6. Induktionsvarmespole ifølge krav 5, kendetegnet ved, at kølesystemet omfatter en rørbro, gennemstrømmet og omgivet af kølemiddel, som i midtpunktet af spolens overside er i kontakt med de strømførende segmenter.
7. Fremgangsmåde til smeltning af granulat af halvledermateriale på en tallerken med et udløbsrør ved hjælp af en induktionsvarmespole, omfattende dannelsen afen film af smeltet halvledermateriale, som fugter udløbsrøret, og en smeltemasse af halvledermateriale med en fri overflade, som er omgivet af filmen, kendetegnet ved, at filmen og smeltemassen opvarmes på den frie overflade ved hjælp af strømførende segmenter, der fremstår i midtpunktet for induktionsvarmespolens underside, og som via et forbindelsesstykke er elektrisk ledende forbundet på en nedre ende.
8. Fremgangsmåde ifølge krav 7, kendetegnet ved, at granulat af silicium smeltes på en tallerken af silicium.
9. Fremgangsmåde ifølge krav 6 eller krav 7, kendetegnet ved, at forbindelsesstykket og smeltemassen lægges på det samme elektriske potentiale.
