Kaolin wool: cov kev pab cuam thiab Scope

Vata muaj kaolin mullite fiber ntau thiab yog dej num raws li thermal rwb thaiv tsev cov ntaub ntawv. Nws txawv resistant rau hluav taws thiab tseem siv tau los sau cov voids nyob rau hauv lub masonry thiab tsiaj hiav txwv qhov qhib.

piav qhia

Material yog feem ntau siv rau hauv daim ntawv ntawm qaws. Nws yuav ua nyob rau hauv tus txheej txheem ntawm melting silicon oxides thiab txhuas nyob rau high school kub nyob rau hauv tshwj xeeb furnaces. Kaolin wool rau ntau xyoo nquag siv rau lub thermal rwb thaiv tsev ntawm cov vaj tse thiab outperforms ntau lwm yam ntaub ntawv. Txawm tias cov niaj hnub ntau yam ntawm lwm yam tshuaj mas siv nrog zoo xws li cov zog, nws yog ua ntau nrov thiab pom nws siv nyob rau hauv muaj daim ntaub ntawv. Nws ua raws li ib tug thermal rwb thaiv tsev pab kiag li lawm, combustion lag, Thaum tshav kub kub exchangers thiab turbines. Cov feem ntau lug sau tseg nyob rau hauv qhov kev lag luam. Tsis tas li ntawd kaolin wool yog siv nyob rau hauv qhov siv thiab ua slabs thiab lwm yam molded khoom.

Cov khoom muaj ib tug high level suab thiab tshav kub rwb thaiv tsev, ua hauj deformation thiab kev co loads. Nyob rau hauv tas li ntawd, paj rwb muaj lwm thaj chaw uas yog cov yam ntxwv ntawm ntau yam ntaub ntawv nrog ib tug zoo xws li cov hom phiaj. Lub insulating txhais tau tias yog tsis cuam tshuam los ntawm high kub nyob rau hauv nruab nrab los yog oxidizing ib puag ncig, cov theem ntawm kuj yuav muab ntau zog los ntawm kev siv ntawm chromium oxide. Dua li no, lub ntsiab feature yog kom muaj lub tshav kub yog tshuam txo nyob rau hauv ib tug txo cua.

zoo

Vata MKRR-130 yog zoo tagnrho rau cov creation ntawm tus nres tas, rwb thaiv tsev poob lawm ntawm ncu thiab phab ntsa Siv. Nws yam tsawg kawg nkaus hnyav thiaj li tau nyiaj uas yuav tsum tau lub sij hawm thiab kev rau siab yuav tsum tau rau installation thiab thiaj li roj nqi. Nws yog ib nqi sau cia lwm txoj kev:

• kom huv si ntxuav fibers yog yus muaj los ntawm siab kuj mus devitrification;
• yam tsawg kawg nkaus txog qib uas tshav kub txuam nrog;
• kuj mus thermal poob siab;
• preservation ntawm tus thawj yam ntxwv thaum lub sij hawm rov siv;
• ib tug high degree ntawm lub suab rwb thaiv tsev;
• Nws yog tsis cuam tshuam los ntawm kev txhoj puab heev tshuaj, alkalis thiab hlau melts;
• inert rau roj raws li ntxhia roj, thiab dej vapor;
• hluav taws xob yam ntxwv nyob twj ywm unchanged txawm sov siab.

nta

Kaolin wool ua los ntawm refractory alumina, uas yog raws li nyob rau hauv quartz xuab zeb. Nyob rau hauv ib tug tshwj xeeb ore-smelting cub tawg yog melted ntawm ib tug kub ntawm 1800 degrees. Nyob rau hauv lub melting tsam muaj peb electrodes, thaum nyob rau hauv lub qhov chaw ntawm lawv cov tiam tsuas yog ob tug. blowing txheej txheem yog siv rau melting cov khoom, nws yog raws li nyob rau hauv tej yam tshwj xeeb chav muab hais tias ib tug siab ntawm txog 0.7 MPa. Ncaws tawm nozzle tso cai rau tso cai ntawm tag nrho cov tshuab txheej txheem. Raws li binders yuav ua dej iav, av nplaum los yog xis mas.

Vata kaolin muag nyob rau hauv yob ntawm mus txog rau 10 meters nyob rau hauv ntev, thickness thiab dav ntawm 2 cm thiab 60 cm, ntsig txog. Nws yog saj zawg zog, li no muab ib tug snug haum rau tej kev tsim. Niaj hnub no, manufacturers tseem tabtom txhim kho cov ntaub ntawv uas los ntawm qhov sib ntxiv ntawm ntxiv Cheebtsam, piv txwv li yttria. Qhov no pab cov stability ntawm lub fibers thiab nthuav siv possibilities.

Ntaub ntawv resistant rau hluav taws

Refractory ntaub ntawv ua los ntawm mineral bases thiab yog resistant rau kev kub muaj peevxwm, thiab lawv cov yam ntxwv nyob twj ywm unchanged. Lawv yog cov tseem ceeb nyob rau hauv lub steel kev lag luam rau distillation, nrov heev nthe thiab lwm yam dab, tus creation ntawm mechanisms ntawm high-kub (motors, reactors) thiab yam rau lawv. Tom qab siv refractories yuav muab xa mus rau ub.

Feem ntau cov feem ntau, qhov no hom ntawm cov khoom muaj ib lub zoo lawm thiab tsis tshua muaj qhov hnyav, uas ua rau lawv zoo tagnrho rau ntau yam hauv ob sab phlu. Tam sim no, muaj yog ib tug yooj yim yuav txo tau nyob rau hauv zus tau tej cov refractories, raws li ntau mloog yog them rau zus tau tej cov tshwj xeeb mortars thiab concretes, resistant mus rau high kub.

Refractory ntawv uas siv: manufacturing txoj kev

ntaub ntawv Lawv muaj ib tug tej hub matrix ua los ntawm refractory borides, nitrides, oxides thiab muaj ib theem siab ntawm tshuaj inertness thiab durability. Tsis tas li ntawd feem ntau siv carbon compound. Refractory khaws lawv lub zog thaum raug rau ib tug kub ntawm 1600 degrees thiab siv nyob rau hauv ntau qhov chaw nyob qhov twg muaj ib tug xav rau tej kev txiav txim nyob rau hauv qhov muab tej yam kev mob. Raws li txoj kev ntawm txoj kev cov khoom raug muab faib ua ob peb hom:

• kub-nias;
• alloy, kev los ntawm cov yaj;
• yas txoj kev;
• alloy raws li nyob rau hauv cov kua penoshlikera;
• txiav los ntawm cov tiav blocks los yog pob zeb.
