Dab tsi yog qhov sib txawv ntawm cov cement castables thiab tsoos castables?
Muaj qhov sib txawv loj ntawmqis cement castablesthiab tsoos castables, feem ntau nyob rau hauv qhov sib txawv ntawm nruab nrab lub sij hawm lub zog thiab lig-theem zog. Cov tsoos castables muaj lub zog nruab nrab lub sij hawm tsis zoo, thaum cov cement castables qis dua zoo dua li cov tsoos refractory castables. Tsis tsuas yog cov cement ntau npaum li cas qis, cov ntsiab lus calcium tsawg, thiab tseem siv ultra-nplua hmoov tshuab los faib cov castable particles nyob rau hauv ib tug tsim nyog proportions, thiab lub lig-theem zog thiab nruab nrab lub sij hawm lub zog ntawm lub castable yog ntxiv txhim kho.
Piv nrog cov tsoosrefractory castables, Cement Castables muaj qhov ntom ntom ntom ntom, porosity tsawg, thiab siab dua chav ntsuas kub kho lub zog; lawv kuj muaj qhov ntim zoo ruaj khov thiab muaj cov ntim me me tom qab ziab thiab calcining. Cov khoom siv high-zog low-cement hauv cov cement castables yog tsim nrog cov ntshiab calcium aluminate cement ua tus neeg sawv cev khi. Qhov siab tshaj plaws kev pab cuam kub ntawm high-strength castables ncav cuag 1600 degree, thiab nws muaj zoo hnav tsis kam ntawm kub kub. High-strength, low-cement castables yog haum rau siv nyob rau hauv ntau yam kiln linings nrog kub kub thiab muaj zog corrosiveness.
Cov khoom siv qis-cement siv fused dawb corundum ua aggregate hu ua corundum low cement castables. Cov khoom siv corundum-raws li qis-cement muaj lub zog txhua yam, tiv taus yaig thiab puas, thiab qhov siab tshaj plaws kev pabcuam kub ncav cuag 1700. degree, qis cement corundum castable yog tsim rau siv hauv cov cement kiln loj qhov ncauj, ntau lub tog raj kheej txias lub luj tshib thiab lwm yam. hauv ob sab phlu qhov chaw qhov kub siab tshaj 1400 degree thiab qhov kev cuam tshuam puas hnyav heev. Thiab nws yog tsim rau siv nyob rau hauv txhua qhov chaw ntawm lub qhov cub hauv ob sab phlu tshaj 1400 degree.
Cov tsoos refractory castables yog ua los ntawm refractory hais thiab hmoov, nrog rau siab alumina cement. Cov particle gradation ntawm qhov sib sau ua ke tsis zoo li cov khoom siv cement tsawg. Cov cement hais kuj coarser, thiab qhov feem ntawm cov cement ntxiv yog loj, thiab cov dej ntxiv thaum lub sij hawm tsim kho kuj loj. Tsis tas li ntawd, cov cement ntau ntau thiab cov khoom tsis raug cais tawm, yog li cov khoom siv cement tsis tuaj yeem ua kom muaj dej txaus, tshwj xeeb tshaj yog nyob rau ntawm qhov kub ntawm 800 degree, nws yeej tsis muaj zog, yog li kev ua haujlwm ntawm cov tsoos castables tsis zoo li. qis cement castables.
