Cov Cib Hluav Taws Kub Alumina Siab: Kev daws teeb meem zoo tshaj plaws rau kev siv hauv kev lag luam kub siab

Kev ua haujlwm ntawm cov cub tawg kev lag luam vam khom ntau rau cov khoom siv ruaj khov thiab tiv taus cua sov. Ntawm txhua yam khoom siv refractory,cov cib hluav taws kub alumina siabraug lees paub tias yog ib qho ntawm cov kev xaiv txhim khu kev qha tshaj plaws rau kev tsim khoom niaj hnub no. Siv dav hauv kev ua hlau metallurgy, kev tsim cement, kev tsim tshuaj lom neeg thiab kev ua cov khoom siv ceramic, cov cib refractory alumina siab tswj tau qhov ruaj khov thermal zoo heev thiab lub zog kho tshuab hauv qab qhov kub siab heev. Nrog rau kev txhim kho tas li ntawm cov qauv kev tsim khoom hauv kev lag luam, cov cib hluav taws kub alumina siab tsim nyog tau dhau los ua qhov tseem ceeb rau kev ncua lub neej ua haujlwm ntawm lub cub tawg thiab txo cov nqi khiav lag luam hauv Hoobkas.

Qhov zoo tshaj plaws ntawm cov cib hluav taws kub alumina siab yog lawv cov alumina oxide siab, txij li 48% txog 80%. Cov alumina siab dua ua rau cov cib hluav taws kub dua, ua rau cov cib hluav taws kub tiv taus qhov kub ua haujlwm tas mus li ntawm 1400 ℃ thiab 1790 ℃. Piv nrog cov cib hluav taws kub av nplaum txheem, cov cib hluav taws kub alumina siab zoo tshaj plaws muab kev tiv thaiv corrosion zoo dua, tiv thaiv slag erosion muaj zog thiab ruaj khov thermal shock zoo heev. Lawv tiv taus kev tawg thiab deformation nyob rau hauv qhov kub hloov pauv ntau zaus, tiv thaiv kev puas tsuaj rau lub qhov cub thiab txo qis kev saib xyuas thiab lub sijhawm tsim khoom tsis tau npaj tseg.

Peb cov cib hluav taws kub alumina siab yog tsim los ntawm cov khoom siv bauxite ua los ntawm kev kub siab sintering thiab kev tshuaj xyuas zoo nruj, ua raws li cov qauv thoob ntiaj teb kev lag luam refractory. Peb muab cov cib refractory txheem thiab kev cai loj uas haum rau rotary kilns, blast furnaces, cua sov furnaces thiab ntau yam khoom siv thermal industrial. Txhua pawg ntau lawm raug kuaj xyuas qhov ceev, lub zog compressive, refractoriness thiab lwm yam cim tseem ceeb kom ntseeg tau tias muaj kev ruaj khov thiab txhim khu kev qha rau cov neeg yuav khoom lag luam thoob ntiaj teb.

Kev ua tau zoo ntawm tus nqi yog qhov laj thawj tseem ceeb uas ua rau cov cib hluav taws kub alumina siab tau txais kev siv dav thoob ntiaj teb. Piv nrog cov khoom siv refractory fused zoo, cov cib alumina siab sib npaug kev ua tau zoo thiab tus nqi sib tw. Lawv lub neej ua haujlwm ntev txo cov zaus hloov khoom siv, cov nqi zog ua haujlwm thiab kev poob ntawm kev kaw ntau lawm, ua rau lawv yog qhov ruaj khov thiab pheej yig thermal rwb thaiv tsev thiab kev daws teeb meem refractory rau cov lag luam me, nruab nrab thiab loj.

Thaum kev tsim khoom lag luam thoob ntiaj teb txav mus rau kev ua haujlwm zoo dua thiab siv hluav taws xob tsawg dua, qhov kev xav tau ntawm kev ua lag luam rau cov khoom siv refractory zoo tseem pheej loj hlob. Cov chaw tsim khoom siv hluav taws kub alumina siab txuas ntxiv txhim kho cov txheej txheem tsim khoom kom txhim kho kev ua haujlwm rwb thaiv tsev thiab cov khoom ruaj khov. Rau cov chaw tsim khoom lag luam uas tab tom nrhiav cov ntaub ntawv hauv qhov cub kom ntseeg tau, cov cib refractory alumina siab uas tau kuaj zoo, ua raws li txoj cai tag nrho thiab hloov kho tau yog qhov kev xaiv zoo tshaj plaws los txhawb kev ua haujlwm zoo dua thiab txo qis kev nqis peev mus sij hawm ntev.

Cov khoom siv hauv qhov cub sib txawv thiab cov xwm txheej ua haujlwm xav tau cov ntsiab lus alumina, qhov loj me, kev tiv taus compression thiab cov yam ntxwv tiv taus cua sov. Yog tias koj tab tom npaj kho qhov cub, yuav khoom siv refractory lossis hloov khoom siv kho, xav tiv tauj peb txhua lub sijhawm. Txhawb nqa los ntawm cov txheej txheem tsim khoom laus thiab cov pab pawg kws tshaj lij, peb tuaj yeem phim cov qauv cib hluav taws kub alumina siab tshaj plaws raws li koj cov xwm txheej ua haujlwm tshwj xeeb thiab cov yam ntxwv ntawm qhov cub, muab cov kev daws teeb meem dawb, cov lus hais raug thiab cov kev pabcuam yuav khoom ib zaug los pab cov chaw tsim khoom tswj cov nqi thiab txhim kho kev ruaj khov ntawm qhov cub.
