Classification thiab ntau lawm txoj kev ntawm lub teeb refractories
Nyob rau hauv tsab xov xwm no, Henan refractory cib manufacturers xav tham nrog koj txog kev faib thiab ntau lawm txoj kev ntawm lub teeb refractories. Lub teeb refractories xa mus rau refractories nrog siab porosity, tsawg bulk ceev thiab tsawg thermal conductivity. Lub teeb refractories muaj cov qauv ntxeem tau (qhov porosity feem ntau yog 40-85%) thiab thermal rwb thaiv tsev siab.
Muaj ntau ntau txoj kev muab faib rau lub teeb refractories
1. Muab faib los ntawm qhov ntim ceev. Lub teeb ci ci nrog qhov ntom ntom ntawm 0.4 ~ 1.3g / cm ~ 2 thiab ultralight cib nrog qhov ntom ntom tsawg dua 0.4g / cm ~ 2.
2. cais los ntawm kev ua haujlwm kub. Daim ntawv thov kub 600 ~ 900 ℃ yog cov khoom siv rwb thaiv tsev kub tsawg; 900 ~ 1200 ℃ yog nruab nrab kub rwb thaiv tsev khoom; saum toj no 1200 ℃ yog kub rwb thaiv tsev cov ntaub ntawv.
3. Muab faib los ntawm cov khoom zoo. Ib qho yog tsim lub teeb ci ci ci, nrog rau cov av nplaum, siab alumina, silica thiab qee cov oxide ntshiab cib; lwm yam yog unshaped lightweight refractory khoom, xws li lub teeb yuag refractory pob zeb.
Lub tshav kub cia poob thiab kub dissipation poob ntawm qhov chaw ntawm lub tshuab kiln lub cev feem ntau suav rau 24 txog 45% ntawm cov roj noj. Kev siv lub teeb ci ci nrog cov thermal conductivity tsawg thiab lub peev xwm kub me me raws li cov khoom siv ntawm lub cub tawg tuaj yeem txuag tau roj; Nyob rau tib lub sijhawm, vim lub cub tawg Nws tuaj yeem ua kom sov thiab txias sai, txhim kho kev tsim khoom ntawm cov khoom siv, txo qhov hnyav ntawm lub cub tawg, ua kom yooj yim rau cov qauv ntawm lub qhov cub, txhim kho cov khoom zoo, txo qhov kub thiab txias. , thiab txhim kho cov xwm txheej ua haujlwm.
Qhov tsis zoo ntawm lub teeb yuag refractories yog loj porosity, xoob qauv thiab tsis zoo slag kuj. Lub slag sai sai nkag mus rau hauv lub qhov hws ntawm lub cib, ua rau nws decompose, thiab tsis tuaj yeem siv ncaj qha rau hauv kev sib cuag nrog molten slag thiab kua hlau; nws muaj zog txhua yam tsis muaj zog, hnav tsis zoo, thiab tsis zoo thermal stability. Nws tsis tuaj yeem siv rau cov khoom siv thauj khoom, thiab tsis tuaj yeem siv rau kev sib cuag nrog cov khoom siv rau hauv qhov cub thiab hnav hnyav. Ntawm qhov chaw.
Vim yog qhov tsis zoo ntawm cov lus hais saum toj no ntawm lub teeb yuag refractory cov ntaub ntawv, qhov chaw ntawm cov kiln muaj kev sib cuag nrog tus nqi, huab cua kub nqa slag, ntws loj, thiab qhov chaw uas muaj kev vibration siab feem ntau tsis siv. Lub teeb yuag refractories feem ntau yog siv los ua kev txuag hluav taws xob los yog cov ntaub ntawv khaws cia kub rau cov kilns.
