Kev siv cov xwm txheej ntawm Bauxite hauv Brown Corundum Kev Lag Luam hauv Suav teb
Brown corundum yog ib yam ntawm cov khoom siv dag zog, vim nws qhov siab hardness, kub oxidation kuj, zoo tshuaj stability, zoo heev sib tsoo kev ua tau zoo, raws li ib tug refractory raw khoom thiab abrasive yog lug siv nyob rau hauv ceramics, metallurgy, tsev cov ntaub ntawv thiab mechanical ua. thiab lwm yam teb.
Bauxite yog cov khoom siv tseem ceeb rau smelting xim av corundum, thiab tseem yog qhov yuav tsum tau ua ua ntej rau kev ciaj sia ntawm xim av corundum kev lag luam. Feem ntau ntawm Tuam Tshoj cov khoom siv bauxite yog siv los smelt hlau txhuas, thiab tsuas yog ib feem me me yog siv los ua raw khoom rau cov ntaub ntawv refractory, corundum sib tsoo cov ntaub ntawv, ceramics thiab lwm yam khoom siv tshuaj lom neeg kev lag luam. Tam sim no, Tuam Tshoj qhov nruab nrab txhua xyoo kev siv cov khoom siv bauxite kwv yees li 14 lab tons (nrog rau cov ore imported), ntawm cov kev lag luam aluminium 12 500 txog 13 lab tons, cov ntaub ntawv refractory thiab abrasives 11 txog 12 lab tons (xws li hluav taws xob yaj, siab bauxite. clinker thiab siab aluminium cement, thiab lwm yam), ceramics thiab lwm yam lag luam 4 mus rau 5 lab t. Nrog rau kev nthuav dav sai ntawm alumina muaj peev xwm hauv Suav teb, cov khoom siv zoo bauxite rau xim av corundum smelting yuav nruj zuj zus.
Qhov tsis muaj cov khoom siv bauxite zoo, ua rau tus nqi ntawm bauxite nce, tus nqi ntawm lub teeb hlawv bauxite tom qab lub cev qhuav dej tau tawg los ntawm txhiab yuan, tus nqi ntawm bauxite siv rau hauv cov nqi ntawm cov xim av corundum smelting accounted txog li 1. / 3 mus rau 1/2 nruab nrab ntawm, thaum smelting xim av corundum bauxite qib kuj poob qis, Qhov qis ntawm qib txhais tau hais tias cov ntsiab lus ntawm cov ntxhia impurities nyob rau hauv cov ntaub ntawv raw ntawm smelting xim av corundum yuav nce, uas yuav tsis tsuas cuam tshuam cov txheej txheem smelting thiab cov khoom. zoo, tab sis kuj zoo heev nce lub zog noj ntawm smelting. Tam sim no tus nqi ntawm hluav taws xob thiab graphite electrodes tseem nce ntxiv, thiab cov smelting xim av corundum feem ntau yog nyob ntawm kev hloov hluav taws xob hluav taws xob rau hauv hluav taws xob hluav taws xob kom yaj thiab txo cov khoom siv, thiab cov khoom siv hluav taws xob yog 2/5 txog 1/2 ntawm tus nqi tsim khoom smelting. Hauv cov ntsiab lus, cov xwm txheej no tau ua rau cov nqi ntau lawm ntawm cov xim av corundum, thiab cov nqi tsim khoom ib tuj ntawm xim av corundum block smelting tau mus txog ntau dua 3,000 yuan. Qhov nce ntawm kev siv hluav taws xob thiab cov nqi tsim khoom ntawm smelting xim av corundum ua rau muaj sia nyob siab ntawm xim av corundum ntau lawm cov lag luam, thiab cov nyiaj tau los yog nyias lossis txawm poob. Brown corundum raws li tus nqi qis ntawm cov khoom tau nyuaj dua rau tus nqi siab, thiab tam sim no qee cov tuam txhab me thiab nruab nrab xim av corundum ntau lawm hauv Suav teb tau nres ntau lawm vim cov nqi smelting tsis tuaj yeem khaws cia.
