Babban Ingancin Kayan Aiki Mai Tsauri Farin Alumina Grits tare da Samfurin Kyauta
Farin alumina mai haɗewa / Farin CorundumGritwani abu ne mai ƙarfi, wanda aka yi shi da foda mai inganci na alumina ta hanyar narkewa sama da digiri 2000 a cikin tanderun lantarki da sanyaya, wanda aka rarraba shi zuwa girman hatsi daban-daban. Farin alumina da aka haɗa shine babban kayan da ake amfani da su wajen samar da kayan da ba su da siffa da siffa.
An yi farin alumina da aka haɗa da foda mai ƙarancin sodium ta hanyar narkewa a yanayin zafi mai yawa, sanyaya kristal, sannan a niƙa. Farin alumina da aka haɗa yana ƙarƙashin iko mai ƙarfi don kiyaye rarrabawar girman hatsi da kuma kamannin da ya dace.
Ana amfani da shi sosai a cikin kayan ladle castables, kayan aikin ƙarfe, kayan haɗin bindiga mai hana ruwa gudu da sauran samfuran monolithic masu hana ruwa gudu; Don kayan da aka yi da siffa mai hana ruwa gudu, ana amfani da shi galibi a cikin kayan aiki masu inganci na tubalin corundum, corundum mullite, tubalin toshe mai jure ruwa na ƙarfe mai laushi, bindigar feshi mai haɗaka, yin ƙarfe da masana'antar siminti mai ci gaba.
Hakanan ana iya amfani da shi azaman kayan gogewa, simintin daidaitacce, feshi da shafi, da yumbu na musamman
