| titleOfInvention | IMPROVED PROCESS FOR REMOVAL OF ALUMINUM AND CALCIUM IN SILICON AND SILICON-BASED ALLOYS |
| abstract | THE INVENTION CONCERNS AN IMPROVEMENT OF THE PROCESS FOR REMOVING ALUMINUM AND CALCIUM FROM SILICON AND SILICON-BASED ALLOYS, SUCH AS FERROSILICON CONTAINING AT LEAST 40 SILICON. THE PROCESS CONSISTS OF INJECTING INTO THE SILICON OR THE LIQUID SILICON ALLOY, THROUGH THE AXIAL TUBE OF THE DOUBLE-FLOW TUBE, SEQUENTIALLY OR SIMULTANEOUSLY, OXYGEN AND AT LEAST ONE SUBSTANCE CONTAINING AT LEAST ONE ACTIVE ATOM CHOSEN FROM AMONG THEM. OXYGEN, CHLORINE AND FLUORINE, WHICH IS RELEASED BY THERMAL DECOMPOSITION AT THE TEMPERATURE OF THE LIQUID ALLOY AND WHICH COMBINES WITH ALUMINUM AND CALCIUM GIVING A VOLATILE OR SCORIFIABLE COMPOUND WHICH SEPARATES FROM THE SILICON OR THE ALLOY . |
