Yuav siv cov refractory castables nrog siab indexes yuav zoo dua?
Refractory castablesyog qhov zoo tsuas yog tias lawv muaj cov ntsuas tsim nyog. Cov ntsuas siab yuav tsis tas yuav tsim nyog, tsuas yog cov uas tsim nyog tuaj yeem hais tau zoo.
Refractory castables nrog high indexes muaj lub zog zoo, hnav tsis kam thiab corrosion kuj, tab sis tus nqi kuj siab. Tab sis nws tsis haum rau txhua qhov chaw thiab qhov kub thiab txias.
Kev xaiv yog nyob ntawm qhov sib txawv ntawm qhov kub thiab txias, huab cua thiab theem ntawm kev yaig. Piv txwv li, nyob rau hauv 1100 cheeb tsam, siv corundum castable tsis yog qhov zoo tshaj plaws kev xaiv, vim hais tiascorundum refractory castablemuaj zog heev tab sis kuj nkig. Haum rau siv ntawm qhov kub siab tshaj 1400 degree. Cov khoom tseem ceeb ntawm 1100 corundum castable tsis tuaj yeem siv tau, tab sis cov nyhuv tsis zoo heev vim tias qhov kub thiab txias yog qhov qis thiab qhov tuav ntawm corundum tsis siv. Nws tsis tuaj yeem siv ntawm tus nqi siab thiab cov nyhuv tsis zoo, thiab rov ua dua.
Tau kawg, nyob rau hauv cov ntaub ntawv ntawm qhov kub thiab txias, nws tseem yuav tsum tau xaiv refractory castables haum rau cov ntaub ntawv ntawm qhov kub thiab txias. Vim nws tus nqi siab, qhov ntsuas tau zoo thiab lub neej ua haujlwm ntev, kev ua haujlwm ntawm cov khoom siv refractory castables tuaj yeem siv tag nrho ntawm qhov tsim nyog.
Thaum cov huab cua sib txawv, xaiv cov refractory castables nyob rau hauv cov huab cua sib txawv, xaiv acidic castables nyob rau hauv tib qhov chaw rau acidic atmospheres, thiab xaiv alkaline cua castables rau alkaline cua. Yog hais tias corrosion yog loj, xaiv corrosion-resistant castables; Yog tias hnav hnyav, xaiv castables nrog zoo hnav tsis kam.
Tsis tsuas yog refractory castable nrog cov ntsuas zoo yog qhov kev xaiv zoo, nws yuav tsum tau hais tias yog qhov kev xaiv tsim nyog. Qee tus neeg tsim khoom tsuas yog saib qee qhov ntsuas hauv phau ntawv nug txog kev xaiv, uas yog qhov tseeb thiab tsis tsim nyog. Tsim nyog refractory castables yuav tsum tau xaiv raws li qhov tseeb qhov kub thiab txias, huab cua thiab yaig ntawm lub qhov cub hauv ob sab phlu.
