Qhov sib txawv thiab daim ntawv thov ntawm refractory av nkos, refractory cement thiab refractory castable
Refractory av nkos:
Muaj pes tsawg leeg: Refractory av nkos feem ntau yog tsim los ntawm silicate los yog siab aluminium refractory cov ntaub ntawv, binders thiab lwm yam additives.
Nta: Refractory av nkos muaj cov yas zoo, kev tsim kho yooj yim, tsim rau masonry, kho thiab kev sib txuas ntawm cov khoom siv kub kub ntawm qhov chaw me me. Nws tuaj yeem tiv taus qhov kub siab dua, tab sis qhov kub thiab txias yog qhov tsawg.
Daim ntawv thov: Refractory av nkos feem ntau yog siv rau hauv cov khoom kub kub kho, kho, xau plugging thiab masonry furnace phab ntsa, rauv sab saum toj thiab lwm qhov chaw.
Refractory cement:
Muaj pes tsawg leeg: Refractory cement feem ntau yog tsim los ntawm cov pob zeb refractory, siab alumina thiab lwm yam ntaub ntawv tseem ceeb thiab ib feem ntawm cov ntawv khi.
Nta: Refractory cement muaj qhov kub thiab txias tsis kam thiab corrosion kuj. Nws yog ib yam ntawm cov khoom siv refractory, uas yog tsim rau tag nrho cov qauv ntawm cov khoom siv masonry siab kub, thiab muaj zog compressive zoo thiab stability.
Daim ntawv thov: Refractory cement feem ntau yog siv rau masonry furnace lub cev, kiln, rauv thiab lwm yam high-temperature khoom tag nrho cov qauv, xws li masonry furnace phab ntsa, rauv hauv qab, thiab lwm yam.
Refractory castable:
Muaj pes tsawg leeg: Refractory castable yog tsim los ntawm refractory aggregate, binder thiab dej ntxiv tus neeg sawv cev, thiab lwm yam. Lub refractory aggregate yuav ua tau siab aluminium aggregate los yog silicon carbide.
Nta: Lub refractory castable yog kua lossis semi-kua, uas tuaj yeem nchuav rau hauv cov khoom siv kub kub los ntawm kev nchuav, txau thiab lwm txoj hauv kev. Nws muaj qhov zoo ntawm qhov kub thiab txias tsis kam, thiab yog qhov tsim nyog rau cov khoom siv kub kub nrog cov duab thiab cov qauv sab hauv.
Daim ntawv thov: Refractory castables feem ntau yog siv los kho, sib khi thiab tso rau hauv cov khoom siv kub, xws li tso rau sab saum toj, hauv qab thiab nraub qaum ntawm lub qhov cub phab ntsa.
Hauv cov ntsiab lus, cov av nkos refractory yog tsim los kho thiab koom nrog cov khoom me me, cov cement refractory yog tsim rau tag nrho cov qauv masonry, thiab refractory castable yog tsim rau pouring complex duab thiab sab hauv. Raws li kev siv tshwj xeeb xav tau thiab cov khoom siv, xaiv cov khoom siv refractory tsim nyog rau daim ntawv thov. Thov nco ntsoov tias cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb, thiab nws raug nquahu kom sab laj nrog cov kws tshaj lij refractory manufacturers lossis cov kws tshaj lij thaum xaiv qhov tiag.
Refractory av nkos, refractory cement, refractory castable yog tag nrho cov khoom siv amorphous refractory, thiab feem ntau siv hauv kev lag luam refractory. Refractory av nkos yog siv rau masonry refractory bricks, refractory av nkos, los yog refractory mortar los yog cov khoom sib koom ua ke. Siv los ua cov khoom sib koom ua ke rau masonry ntawm cov khoom refractory. Refractory cement yog tsim los ntawm refractory qhob khoom, refractory castable yog ua los ntawm refractory aggregate, hmoov thiab binder, vim hais tias ntawm kev siv ntawm pouring siv kuj hu ua pouring khoom.
Ua ntej, refractory av nkos Refractory av nkos raws li cov khoom yuav muab faib ua av nplaum, siab txhuas, silica thiab magnesium refractory av nkos. Nws yog tsim los ntawm refractory hmoov, binder thiab admixture. Nrog refractory clinker hmoov thiab ib qho tsim nyog ntawm cov av nplaum uas tsim nyog raws li cov ntaub ntawv thiab cov yas ua los ntawm cov av nkos refractory, nws qhov kub thiab txias tsis tshua muaj zog, kub siab rau daim ntawv cog lus ceramic muaj lub zog siab. Qhov luaj li cas ntawm cov av nkos refractory sib txawv raws li daim ntawv thov, thiab nws qhov txwv particle loj feem ntau tsawg dua 1mm, thiab qee qhov tsawg dua 0.5mm lossis finer. Kev xaiv cov khoom siv refractory slurry yuav tsum tau txiav txim siab ua ke nrog cov ntaub ntawv ntawm cov khoom siv refractory ntawm masonry. Ntxiv nrog rau kev siv los ua cov khoom sib koom ua ke, cov av nkos refractory tuaj yeem siv los ua cov txheej txheem kho rau hauv ob sab phlu los ntawm kev hloov kho lossis txoj kev tawg.
Refractory cement Refractory cement tseem hu ua aluminate cement. Aluminate cement yog hydraulic cementing khoom ua los ntawm bauxite thiab limestone, calcined clinker nrog calcium aluminate ua cov ntsiab lus tseem ceeb thiab alumina cov ntsiab lus ntawm li 50%, thiab tom qab ntawd hauv av. Aluminate cement feem ntau yog daj lossis xim av, tab sis kuj grey. Siv raws li hauv ob sab phlu nyob rau hauv industrial kilns.
Thib peb, refractory castable
Refractory castable yog ib hom amorphous refractory uas tau siv dav thiab tsim tam sim no. Nws yog tsuas yog siv los tsim ntau yam ntawm cov cua sov rauv hauv ob sab phlu thiab lwm yam khoom siv. Qee qhov zoo tshaj plaws kuj tuaj yeem siv rau hauv qhov cub smelting. Xws li aluminate cement refractory castable tuaj yeem siv dav hauv ntau lub tshuab cua sov thiab lwm yam slag dawb, tsis muaj kua qaub thiab alkali corrosion ntawm cov khoom siv thermal. Nyob rau hauv qhov chaw corroded los ntawm molten hlau, molten steel thiab slag thiab ua hauj lwm kub yog siab, xws li steel trough, steel chim thiab moj tej tawg rauv lub cev, hlau ditch, thiab lwm yam., nyob rau hauv tej qhov chaw ntawm metallurgical furnaces thiab lwm yam hlab ntsha nrog ncaj qha kev sib cuag nrog. molten slag thiab molten hlau, kev siv zoo phosphate refractory castable kho kuj tau zoo heev.
Los ntawm cov saum toj no peb tuaj yeem pom tias txawm hais tias peb cov khoom yog cov khoom siv amorphous refractory, tab sis kev siv sib txawv heev, thiab txhua yam khoom tau muab faib ua cov qauv sib txawv thiab hom, yog li koj tuaj yeem sab laj cov kws tshaj lij thaum yuav khoom, xaiv cov khoom tsim nyog, yog li ntawd. tsis txhob ncua lub sij hawm tsim kho thiab ua rau tsis tsim nyog poob.
