Abstract

Ved fremstilling av Ti eller en Ti-legering gjennom reduksjon med Ca blir et elektrolyttisk badsalt tatt ut fra en reduksjonsprosess elektrolysert for å utvinne Ca og det elektrolyttiske badsaltet som en fast substans, og utvunnet Ca og elektrolyttisk badsalt leveres til reduksjonsprosessen. Derfor blir varmegenerering undertrykt i reduksjonsprosessen ved anvendelse av latent fusjonsvarme frembrakt av den faste substansen som derved i stor grad forbedrer fremstillingseffektiviteten og den termiske effektiviteten. Ytterligere er reaksjonstemperaturen enkel å kontrollere, og råmaterialtilsetningshastigheten kan økes for effektivt å fremstille Ti eller Ti-legering. Således, ved anvendelse av en opptrekkelektrolysemetode ifølge oppfinnelsen kan faststoff-Ca og elektrolyttisk badsalt oppnås ved lav spenning og høy strømeffektivitet, dvs. med relativt lav kraftkonsumpsjon. Når faststoff-Ca og elektrolyttisk badsalt anvendes som en Ca-kilde ved fremstilling av Ti eller Ti-legering gjennom reduksjon med Ca kan Ti eller Ti-legering effektivt produseres.In the preparation of Ti or a Ti alloy by reduction with Ca, an electrolytic bath salt is taken out of a reduction process to be electrolysed to recover Ca and the electrolytic bath salt as a solid, and recovered Ca and electrolytic bath salt are delivered to the reduction process. Therefore, heat generation is suppressed in the reduction process by using latent fusion heat generated by the solid which thereby greatly improves the manufacturing efficiency and the thermal efficiency. Further, the reaction temperature is easy to control, and the raw material addition rate can be increased to efficiently prepare Ti or Ti alloy. Thus, by using a pull-up electrolysis method according to the invention, solid-Ca and electrolytic bath salts can be obtained at low voltage and high current efficiency, i.e. with relatively low power consumption. When solid Ca and electrolytic bath salts are used as a Ca source in the preparation of Ti or Ti alloy through reduction with Ca, Ti or Ti alloy can be effectively produced.
