Av nplaum cib, tseem hu ua sintered cib, yog cov khoom me me rau kev tsim kho. Cov av nplaum nplaum yog ua los ntawm cov av nplaum (xws li shale, coal gangue thiab lwm yam khoom siv hmoov) ua cov khoom siv tseem ceeb, thiab ua tiav, zoo li, qhuav thiab ci nrog av nkos. Qhov sib txawv ntawm cov khoom thiab hollow.
Qhov zoo ntawm av nplaum cib:
1. av nplaum cib tsis muaj zog acidic ntawm qhov kub thiab txias, thiab lawv lub peev xwm los tiv thaiv alkaline slag yaig yog me ntsis zuj zus, tab sis nws nce nrog cov ntsiab lus ntawm Al2O3, thiab lawv cov thermal stability zoo dua li cov silica bricks thiab magnesia bricks.
2. Tom qab ziab, tsim nyog blast furnace av nplaum cib yog impregnated nrog phosphoric acid nyob rau hauv lub tshuab nqus tsev thiab raug rho tawm ob zaug ntawm qhov kub thiab txias, uas yuav siv tau los tsim lub Upper txheej ntawm blast furnace lub cev.
3. Cov av nplaum nplaum yog cov khoom siv hauv zos, pheej yig, ruaj, thiab muaj qhov zoo ntawm kev tiv thaiv hluav taws kub, rwb thaiv tsev kub, suab rwb thaiv tsev, thiab nqus dej noo. Lawv tau siv dav hauv kev tsim vaj tsev engineering, thiab cov khib nyiab tawg tuaj yeem siv los ua cov khoom sib xyaw ua ke.
4. Fly tshauv av nplaum cib siv cov hmoov tshauv ya raws li cov khoom siv tseem ceeb, sib xyaw nrog cov hmoov nplej hmoov av lossis av nplaum thiab lwm yam khoom siv cementing, thiab yog tsim los ntawm batching, molding, ziab thiab roasting, uas tuaj yeem siv tag nrho cov khoom pov tseg thiab txuag roj. .
Kev siv tseem ceeb ntawm av nplaum cib:
1. Cov av nplaum cib feem ntau yog siv hauv kev lag luam metallurgical. Raws li cov khoom siv raw rau kev tsim cov khoom siv refractory zoo li (cib ntawm ntau yam tshwj xeeb) thiab cov ntaub ntawv tsis zoo li refractory, tus nqi suav txog li 70% ntawm tag nrho cov khoom siv refractory. Cov av nplaum tawv hauv cov av nplaum refractory yog siv rau Kev Tsim cov blast furnace refractories, ironmaking furnaces, kub moj tej tawg rauv, hauv ob sab phlu thiab ntsaws cib rau steel nruas, high-alumina av nplaum yog siv los ua aluminium cib, high-alumina hauv ob sab phlu cib thiab high- alumina refractory av nkos rau hluav taws xob furnaces thiab blast furnaces, tawv av nplaum Thiab siab alumina av nplaum feem ntau yog siv los ua clinker calcined ntawm qhov kub thiab txias (1400-1800 degree ).
2. Refractory av nplaum kuj tseem muaj kev siv tseem ceeb hauv kev sib tsoo, kev lag luam tshuaj lom neeg thiab kev lag luam ceramics. High alumina av nplaum yog melted nyob rau hauv ib tug hluav taws xob arc rauv los tsim cov khoom abrasive. Ntawm lawv, fused corundum abrasive yog tam sim no siv ntau tshaj abrasive, accounting rau 2/3 ntawm tag nrho cov khoom abrasive, siab alumina av nplaum yuav siv tau los tsim ntau yam txhuas tebchaw, xws li txhuas sulfate, txhuas hydroxide, txhuas chloride, poov tshuaj txhuas sulfate. thiab lwm yam khoom siv tshuaj. Hauv kev lag luam ceramic, cov av nplaum tawv thiab cov av nplaum zoo ib nrab tuaj yeem siv los ua cov khoom siv niaj hnub siv ceramics, architectural porcelain thiab industrial porcelain.
3. Refractory av nplaum yog siv nyob rau hauv lub tsev ntaub ntawv kev lag luam los ua high-alumina cib, phosphate high-alumina refractory cib, thiab high-alumina fused cam khwb cia bricks rau cement kilns thiab iav melting kilns. High-alumina av nplaum yog calcined thiab ces tov nrog limestone los ua aluminium-muaj cib. Cement, hom cement no muaj cov yam ntxwv ntawm kev teeb tsa ceev, kev tiv thaiv corrosion thiab kub tsis kam.
Cov kauj ruam los ua Clay Cib Hauv Tsev:
Kauj Ruam 1: Kev Npaj Av
Thawj kauj ruam hauv kev ua cov av nplaum yog sib sau ua ke cov av, uas yuav tsum muaj cov av nplaum nplua nuj. Cov av yuav tsum tsis muaj impurities xws li pob zeb, gravel, thiab organic teeb meem. Cov av yuav tsum tau sifted kom tshem tawm tej yam loj hais.
Kauj Ruam 2: Sib tov av thiab dej
Thaum cov av tau sau, nws yuav tsum tau tov nrog dej kom huv si. Cov dej yuav tsum tau ntxiv me me kom txog thaum cov av ntub tab sis tsis ntub heev uas nws ua av nkos.
Kauj Ruam 3: Ntxiv cov khoom siv khi
Cov khoom sib khi yuav tsum tau ntxiv rau cov av sib tov. Qhov no tuaj yeem yog xuab zeb, straw lossis tshauv. Tus nqi ntawm cov khoom sib txuas ntxiv yog nyob ntawm hom av thiab qhov sib xyaw uas koj xav ua kom tiav. Kev sib tov yuav tsum tau ua kom huv si kom ntseeg tau tias cov khoom sib khi yog sib npaug.
Kauj Ruam 4: Hloov cov cib
Txhawm rau tsim cov cib, koj yuav tsum tsim cov pwm, uas tuaj yeem ua los ntawm ntoo lossis hlau. Cov pwm yuav tsum yog qhov xav tau loj thiab cov duab ntawm lub cib. Tom qab ntawd cov av sib tov yog muab tso rau hauv pwm thiab compacted siv trowel los yog duav. Thaum cov pwm puv lawm, sab saum toj yog smoothed, thiab cov cib yog sab laug kom qhuav.
Kauj Ruam 5: Qhuav cov cib
Cov cib yuav tsum tau tso kom qhuav rau ob peb hnub. Lub sijhawm no, lawv yuav tsum tau tiv thaiv los ntawm nag, tshav ntuj ncaj qha, thiab cua daj cua dub. Thaum cov cib qhuav lawm, lawv tuaj yeem muab tso rau thiab khaws cia rau tom qab siv.
