Muaj ib hom abrasive grain nyob rau hauv alumina oxide tsev neeg, uas muaj ib tug rose liab xim, hu ualiab fused alumina. Qhov zoo nkauj zoo nkauj no los ntawm kev ntxiv ntawm chrome oxide (＜0.5 feem pua Cr2O3) nyob rau hauv cov txheej txheem smelting. Thaum ntxiv chrome oxide ntxiv (＜2 feem pua Cr2O3), cov ntaub ntawv qhia ib tug sib sib zog nqus liab xim, ces peb tau ruby fused alumina. Cov chrome oxide tivthaiv ua kom muaj zog ntxiv piv nrog dawb fused alumina, thiab tseem txhim kho nws cov peev xwm sib tsoo.
Lub hardness ntawm liab fused alumina yog ze rau ntawmdawb fused alumina, nws toughness yog siab dua li ntawm dawb fused alumina, tab sis qis dua cov xim av fused alumina, thiab nws kev sib tsoo efficiency kuj siab dua li cov dawb fused alumina. Cov cuab yeej abrasive ua los ntawm paj yeeb fused alumina muaj qhov ua tau zoo thiab ua haujlwm siab.
Vim lub feature ntawm zoo toughness, siab hardness thiab muaj zog sib tsoo efficiency, liab fused alumina muaj ib tug ntau dua kev ua hauj lwm zoo tshaj li cov dawb fused alumina thaum siv los ua cov ntaub ntawv tawv. Pink fused alumina yog tsim rau kev tsim cov vitrified abrasives rau kev ua hauj lwm hardened steels thiab alloys nrog tensile zog tshaj 50 kg / mm². Nws kuj yog siv rau hauv cov cuab yeej sib tsoo, pom thiab riam-sharpening daim ntaub ntawv, precision sib tsoo, profile sib tsoo, flute sib tsoo, hniav sib tsoo, qhuav sib tsoo ntawm cov ntu ntu thiab cov ntsiab lus / lub log.
