Cov yam ntxwv technical ntawm refractory tshuaj pleev xim:
Cov hluav taws-resistant tshuaj ntsuam txheej yog tsim nrog cov txheej txheem txau. Cov khoom sib tov sib piv, cov kev ua haujlwm txau, cov nqi rov qab thiab cov khaub ncaws hnav yog raws li hauv qab no. Qhov sib xyaw sib xyaw ntawm cov txheej txau uas yuav tsum tau ua kom tau raws li cov yuav tsum tau ua hauv qab no: kom ua tiav lub zog hauv qab no: kom ua tiav lub zog uas yuav tsum muaj, kom ua tau cov hmoov av tsawg dua, cov nplaum zoo thiab tsis muaj qhov thaiv ntawm cov raj dej. Thaum cov ceg xis nyob zoo yog siv rau qhuav lossis ib nrab txau txau, tus nqi ntawm cov cement yog li 20% ~ 25% ntawm tag nrho cov khoom siv. Thaum cov cement ntau dhau, cov plua plav tuaj yeem nce ntxiv thaum cov tshuaj tsuag tsuag tau txau, thiab cov shrinkage ntawm cov tshuaj pleev cov tshuaj pleev cov txheej ntxiv nce ntxiv tom qab ua kom tawv nqaij tawv.
Refractory txau cov txheej yog ib cov khoom siv kho amorphous tsim los ntawm cov tshuab nqus dej siv cov cuab yeej pneumatic. Nws yog tsim los ntawm refractory aggregate, hmoov, binder (lossis sab nraud tus neeg sawv cev). Txij li cov cement thiab kev sib sau ua ke thiab lwm cov ntaub ntawv tivthaiv tau sib cais ntau dua thaum cov khoom txau, cov txau txheej muaj qhov ntom ntom ntom nti thiab tshuab muaj zog. Txau kev siv yeej ua haujlwm sib txuas, pouring lossis tamping rau hauv ib txheej txheem, tsis muaj lossis tsuas yog xav tau ib qho kev kawm ib leeg. Cov txheej txheem yooj yim, txuag tau, thiab muaj ntau yam ntawm kev yoog tau.
Raws li lub volume ntawm cov khoom siv, kho cov txheej txau ua kom sib cais ua rau cov tshuaj tsuag lub teeb ({}}. 5 ~ 1.3g / cm3), nruab nrab thiab hnyav tsuag co coease (1.3 ~ 1.8g / cm2) Thiab cov tshuaj tsuag hnyav (> 1.8g / cm3). Lub teeb tshuaj txau lub teeb feem ntau siv los ua thermal rwb thaiv tsev, nruab nrab thiab nruab nrab kub cov raj tshuaj yog feem ntau siv cov kab yees ua haujlwm. Raws li kev txiav txim ntawm cov dej ntxiv (lossis cov tshuaj) thiab cov nyiaj siv, muaj peb hom tshuaj tsuag: ntub dej, ib nrab, ib nrab. Txoj kev ntub dej yog kom sib xyaw cov khoom txau rau hauv cov av nkos ua ntej txau; Txoj kev ua kom qhuav yog ntub dej txau txheej ua ntej, nias nws rau lub nozzle ua ntej, nias nws rau lub nozzle thiab tom qab ntawd ntxiv cov dej seem (lossis daws); Txoj kev qhuav siv tag nrho cov dej (lossis daws) ntxiv rau ntawm lub nozzle. Ntawm lawv, txoj kev ua ib nrab yog qhov feem ntau siv.
