PROCEDIMIENTO PARA PREPARAR SILICIO A PARTIR DE UNA MATERIA PRIMA DE CUARZO EN UN HORNO ELECTRICO DE CUBA BAJA |
摘要 |
<p>An electric low-shaft furnace is charged with the raw quartz in granular form together with briquettes of a quartz/carbon reducing agent having excess carbon (>50 wt %) in relation to the reaction SiO2 + 3C = SC + 2CO, the quartz in the briquetted reducing agent is first converted to SiC plus activated carbon at a temperature below 1600 DEG C in an upper section of the furnace, and the molten raw quartz is then reduced at a temperature above 1600 DEG C in a lower section of the furnace.</p> |
