Refractory Fire Clay Cib

Refractory Fire Clay Cib

Av nplaum cib yog siv dav hauv kev tsim kho vim lawv cov nqi qis thiab muaj kev yooj yim. Txawm li cas los xij, thaum nws los txog rau cov ntawv thov kub xws li cov rauv thiab cov kiln, av nplaum cib tsis txaus. Qhov no yog qhov uas refractory bricks tuaj ua si. Refractory bricks, tseem hu ua hluav taws cib, yog tsim los tiv taus kub thiab siv ntau yam kev lag luam.

Muaj ntau ntau hom refractoryhluav taws av nplaum cib, uas tau muab faib ua alumina bricks, siliceous cib, volcanic pob zeb cib, ceramic cib, thiab lwm yam. Ntawm lawv, alumina cib ua tau zoo nyob rau hauv qhov kub thiab txias ib puag ncig nrog nws siab melting point, tsis tshua muaj coefficient ntawm thermal expansion thiab zoo tshuaj stability. Siliceous bricks muaj cov yam ntxwv ntawm erosion kuj thiab zoo kub kuj. Volcanic pob zeb cib yog lub teeb yuag thiab feem ntau siv rau kev rwb thaiv tsev kub, lub suab nqus thiab kev sib cais. Ceramic bricks, xws li hluav taws kub-cov pob zeb cib tiv taus, muaj kev tiv thaiv corrosion zoo thiab muaj zog kub ua haujlwm, thiab tuaj yeem siv dav hauv tshuaj, metallurgy, khoom siv hauv tsev thiab lwm yam lag luam.

 

Daim ntawv thov teb ntawm refractory hluav taws kub av nplaum cib yog dav heev. Nws yog feem ntau siv nyob rau hauv high-kub reactors, furnaces, kilns, tswb kilns, steel kev lag luam furnaces, metallurgy, iav kev lag luam, ceramic kev lag luam thiab lwm yam high - cov khoom kub, thiab yog dav siv nyob rau hauv ntau yam kev tsim kho. Refractory av nplaum cib kuj tseem siv tau rau hauv cov pa roj carbon monoxide, cua sib cais, muaj cua sov thiab lwm yam lag luam.

 

Cov khoom siv los tsim cov hluav taws kub refractory av nplaum yog qhov tseem ceeb heev rau lawv qhov zoo. Spain yog nplua nuj nyob rau hauv ntuj alumina deposits uas tsis muaj nqi thiab zoo zoo. Cov alumina bricks tsim los ntawm cov khoom siv no muaj kev ua haujlwm zoo thiab ruaj khov, thiab nyiam los ntawm kev lag luam thiab kev tsim kho. Ib yam li ntawd, siliceous bricks feem ntau siv high bauxite, volcanic pob zeb cib siv liab volcanic basalt nplua nuj nyob rau hauv hlau oxide, nyob rau hauv luv luv, zoo raw cov ntaub ntawv yog tus yuam sij rau kev ua tau zoo ntawm refractory av nplaum cib.

 

Fireclay cib, tseem hu ua refractory cib, yog cov khoom siv tseem ceeb hauv kev tsim cov khoom kub - kub thiab cov kilns. Cov cib no yog tsim los ntawm cov av nplaum uas tau raug rho tawm haujlwm ntawm qhov kub thiab txias los ua kom muaj cua sov zoo heev. Ntawm no yog yuav ua li cas ua ib tug firebrick.

 

Kauj Ruam 1: Kev npaj cov khoom siv raw

Thawj kauj ruam hauv kev ua fireclay cib yog npaj cov khoom siv raw. Cov khoom tseem ceeb suav nrog qib siab - cov av nplaum, xuab zeb, thiab cov khoom ntxiv xws li sawdust lossis mov husk. Cov khoom siv raw yog sib xyaw hauv qhov sib npaug kom tsim tau homogenous sib tov.

 

Kauj Ruam 2: Moulding

Cov khoom sib xyaw ua ke yog tom qab ntawd hloov mus rau hauv lub tshuab molding. Lub tshuab molding compresses qhov sib tov nyob rau hauv kev kub siab, tsim ib qho chaw tiaj tus uas txiav thiab zoo li tus cib ntawm qhov xav tau loj.

 

Kauj Ruam 3: Qhuav

Cov bricks molded ces cia kom qhuav. Cov txheej txheem no yog qhov tseem ceeb vim tias cov dej seem seem tuaj yeem ua rau cov cib tawg lossis tawg thaum lawv raug rho tawm haujlwm. Cov txheej txheem ziab tuaj yeem siv li 2-4 lub lis piam nyob ntawm qhov kub thiab av noo. Cib tau qhuav nyob rau hauv lub hnub los yog nyob rau hauv ib tug tshwj xeeb drying chamber.

 

Kauj Ruam 4: Tua tawm

Tom qab ntawd cov cib qhuav tau raug rho tawm haujlwm hauv qhov cub kub ntawm qhov kub ntawm 1200 txog 1800 degree. Qhov no yog ib kauj ruam tseem ceeb hauv kev tsim khoom vim nws muab cov cib lawv lub zog thiab thermal kuj. Thaum tua hluav taws, cov molecules nyob rau hauv cov av nplaum sib tov sib xyaw ua ke los tsim cov qauv ntom ntom. Cov txheej txheem no tuaj yeem siv sijhawm txog 48 teev.

 

Kauj Ruam 5: Kev Tswj Xyuas Zoo

Tom qab tua hluav taws, cov cib raug tshuaj xyuas rau kev tswj kom zoo. Cov cib raug kuaj xyuas seb puas muaj cov kab nrib pleb, deformities, lossis lwm yam tsis xws luag uas yuav cuam tshuam rau lawv qhov kev ua tau zoo. Tsuas yog cov cib uas dhau qhov kev ntsuam xyuas zoo tau ntim thiab xa mus rau cov neeg siv khoom.
