PRINCIPALI APPLICAZIONI:
Sabbia di cromite nell’industria della fonderia
Le sue proprietà consentono al materiale di essere utilizzato nelle fonderie di ghisa grigia e acciaio ad alta resistenza come anima e stampo
fabbricazione di sabbia. La sua elevata conduttività termica gli conferisce buone proprietà di raffreddamento, la bassa dilatazione termica dà origine a una buona stabilità dimensionale. La sua basicità essendo prossima alla neutralità consente l’uso di un’ampia gamma di resine
sistemi leganti e leganti inorganici, presenta un’elevata refrattarietà e un’ampia distribuzione setacciante.
Sabbia di cromite nell’industria siderurgica
Nella produzione dell’acciaio, la sabbia di cromite viene utilizzata anche come riempitivo per la protezione della saracinesca scorrevole nelle grandi siviere di stoccaggio dell’acciaio.
Sabbia di cromite nell’industria del vetro
Una volta macinata fino a ottenere una farina fine, la sabbia di cromite viene utilizzata per la produzione di contenitori per bevande in vetro verde.
