Khoom Description
Nyob rau hauv lub xyoo pua 20th, dawb fused yog cov hmoov ua los ntawm kev txo cov bauxite thiab carbon dub ntawm qhov kub thiab txias. Txawm hais tias txoj kev no tuaj yeem tsim cov corundum dawb nrog cov hardness siab, nws cov nqi ntau lawm yog siab heev thiab nws yog ib qho nyuaj rau siv rau ntawm qhov loj. Tom qab ntawd, alumina tau siv los ua cov khoom siv raw los tsim cov corunalumina dawb los ntawm cov khoom siv kub xws li hluav taws xob rauv taws thiab hluav taws xob arc furnaces. Nyob rau hauv cov txheej txheem no, alumina yog thawj melted thiab ces tov nrog lwm yam additives nyob rau hauv high kub los ua dawb corundum. Hom kev tsim khoom no yog pheej yig dua thiab tuaj yeem ua rau ntawm qhov loj.
Nyob rau hauv cov txheej txheem niaj hnub no ntawm 9 mohs hardness dawb fused alumina, feem ntau siv txoj kev yog hluav taws xob arc rauv melting nrog alumina ua raw khoom. Nyob rau hauv txoj kev no, alumina thiab auxiliary cov ntaub ntawv yog ntxiv rau ib tug hluav taws xob arc rauv, uas yog melted thiab tov nyob rau hauv high kub kom txog rau thaum ib tug uniform kua theem. Cov kua theem no yog tom qab ntawd txias, quenched, thiab reheated kom tau txais cov khoom dawb corundum zaum kawg. Txhawm rau kom ntseeg tau cov khoom lag luam zoo, cov txheej txheem tsim khoom yuav tsum tau tswj nruj me ntsis hauv kev npaj hmoov, sintering, dej txau, tshuaj ntsuam xyuas, tu thiab lwm yam.
