Cov neeg siv khoom hauv Mexico tau xaj 45 tons refractory hluav taws cib thiab 36 rolls ceramic fiber pam
Thaum Lub Ib Hlis Ntuj 45 tons refractory hluav taws cib thiab 36 rolls ceramic fiber pam yog ntim rau xa mus rau cov neeg siv khoom hauv Mexico. Zoo siab thiab zoo tus nqi refractory hluav taws cib thiab rwb thaiv tsev thermal cov ntaub ntawv hauv Topower Refractory.
Hauv qab no peb yuav tham txog kev ua tau zoo thiab molding txoj kev ntawm iav kiln nrog av nplaum cib.
Fireclay refractory cib yog cov khoom siv refractory tsim los ntawm cov av nplaum refractory ua raw khoom. Nws yog dav siv hauv kev lag luam. Fireclay cib tau muab faib ua cov av nplaum zoo tib yam, ntau cov av nplaum uas paub zoo, tag nrho cov-rayed av nplaum refractory hluav taws cib thiab siab silicon av nplaum cib.
Av nplaum refractory hluav taws cib yog cov khoom siv acidic refractory, thiab lawv cov acidity maj mam poob qis raws li cov ntsiab lus ntawm AL2O3 hauv cov cib. Nws cov kev taw qhia thermal yog qhov qis tshaj ntawm tag nrho cov ntaub ntawv refractory. Txawm hais tias nws qhov hluav taws kub tsis kam yog siab li 1700 ° C, qhov kub ntawm cov paj ntoo tsuas yog li 1300 ° C. Qhov no yog qhov tsis zoo tshaj plaws ntawm cov av nplaum cib. Yog li ntawd, nws tsis tuaj yeem thauj khoom lossis compressed thaum siv kub. Thaum nws yog eroded los ntawm ib tug loj npaum li cas ntawm R2O, nws softening kub yuav tsum tau ntxiv nqis mus txog 1050 degree C, yog li nws tsuas yog siv nyob rau hauv lub qis qis ntawm lub pas dej ua ke phab ntsa los yog hauv qab ntawm lub pas dej ua ke. Lub thermal expansion tus nqi ntawm av nplaum cib yog qhov tsawg tshaj plaws ntawm cov khoom siv refractory. Nyob rau tib lub sijhawm, vim muaj cov pob zeb me me ntawm cov av nplaum refractory hluav taws cib thiab cov pores me me, nws tau sib npaug sib npaug, uas ua rau muaj kev ntxhov siab yooj yim dua kom tsis txhob muaj, yog li nws muaj zog tiv taus cua sov. Qhov kub ntawm qhov qis ntawm qhov chaw cia khoom cua sov, daim phiaj cib, lub flue thiab cov iav pas dej ua rau txhua hnub, cov khoom siv refractory nyob ze ntawm lub tshuab muab khoom, xws li cov punch, lub tais ntawm lub tais, thiab lwm qhov chaw nyob qhov twg. qhov kub-resistant cuam tshuam yog xav tau, nws tuaj yeem ua lub luag haujlwm tag nrho.
Muaj ntau txoj hauv kev los ua cov av nplaum refractory hluav taws cib, uas tuaj yeem tsim, tinked, squeezed, av nkos pouring molding, thiab siab molding ntawm av nkos. Txawv molding txoj kev, qhov xwm ntawm cov khoom yog txawv heev. Txawm hais tias cov khoom siv tshuaj lom neeg thiab cov khoom siv raw yog tib yam nkaus, qhov xwm txheej ntawm cov cib yuav txawv vim yog cov txheej txheem molding sib txawv. Cov txheej txheem sib txawv yog siv raws li qhov chaw siv sib txawv. Lub tshav kub cia chav sib faib cib, me me cib loj, cov khoom zoo tshaj plaws rau molding nrog cov tshuab siab siab; rau loj-scale pas dej phab ntsa cib, cov khoom zawj bricks, thiab lwm yam. Qhov zoo tshaj plaws av nkos casting txoj kev ntawm lub tshuab nqus tsev tso pa tawm. Nws yog qhov zoo dua los ua nrog pounding.
