Diferencia entre Metalurgia Y Siderurgia 7.2

La metalurgia es la ciencia que se ocupa del estudio de las propiedades, las aplicaciones y los procesos de extracción y elaboración de los metales. La siderurgia es la metalurgia del hierro, el acero y las fundiciones.

En líneas muy generales, el proceso siderúrgico transcurre de la siguiente manera:

Extracción del mineral de hierro, que suele ser oligisto o limonita, aunque también se extrae a partir de la magnetita, la siderita o la pirita.

Separación de la mena (el mineral que contiene el hierro) de la ganga (arena, cal y otros minerales)

Calcinación del mineral o reducción con carbón de coque, en un alto horno para obtener el arrabio, que es un producto formado por hierro que contiene entre el 2,5 y el 4,5% de carbono, además de silicio, manganeso, fósforo, azufre y otras impurezas.

Transformación del arrabio en hierro dulce, fundiciones o acero. Para obtener las fundiciones se deja solidificar el arrabio y después se vuelve a fundir en un horno de cubilote. Para obtener el acero, el arrabio líquido se mezcla con chatarra y mineral de hierro en un mezclador y se envía a diferentes hornos de afino, según el tipo de acero que se quiera conseguir
