Kev soj ntsuam ntawm kev ua haujlwm ntawm cov khoom siv refractory: qhov tseem ceeb los xyuas kom meej cov txheej txheem kub
Raws li cov khoom siv tshwj xeeb, refractory yog dav siv hauv metallurgy, cov khoom siv hauv tsev, tshuaj lom neeg kev lag luam thiab lwm yam txheej txheem kub. Kev ua tau zoo thiab qhov zoo ntawm cov khoom siv refractory yog ze ze rau lawv cov ntaub ntawv raw. Daim ntawv no yuav txheeb xyuas lub luag haujlwm ntawm cov khoom siv raw khoom, nrog rau kev muab cov khoom kub thiab txias, txhim kho lub zog ntawm cov khoom siv refractory thiab cuam tshuam qhov hnav tsis kam ntawm cov ntaub ntawv refractory.
1. Muab qhov kub thiab txias ua haujlwm kom ntseeg tau tias cov txheej txheem ruaj khov
Ib qho ntawm lub luag haujlwm tseem ceeb ntawm refractories yog muab kev kub ntxhov thiab ua kom muaj kev ruaj ntseg hauv qhov kub thiab txias. Lub ntsiab Cheebtsam ntawm refractory raw cov ntaub ntawv, xws li alumina, magnesium oxide, calcium oxide, thiab lwm yam, muaj siab melting point thiab thermal stability, thiab muaj peev xwm tiv thaiv thermal expansion thiab thermal shock ntawm kub. Cov ntaub ntawv nyoos no tau ua ke nrog lwm cov khoom siv los tsim cov ntaub ntawv refractory nrog kub tsis kam, ua kom muaj kev ruaj ntseg ntawm cov txheej txheem kub.
Nyem qhov no mus saib daim duab nyob rau hauv lub qhov rais tshiab
Thib ob, txhim kho lub zog ntawm cov khoom siv refractory, txuas ntxiv lub neej kev pab cuam
Cov khoom xyaw xws li cov nplaum thiab cov khoom siv ntxiv hauv cov khoom siv raw khoom tuaj yeem txhim kho cov qauv ntawm cov khoom siv refractory thiab txhim kho nws cov khoom siv xws li compression, dabtsi yog khoov thiab tensile kuj. Adhesives tuaj yeem khi cov ntaub ntawv raw khoom ua ke los tsim cov qauv tag nrho thiab ua kom lub zog thiab ruaj khov ntawm cov khoom. Tus neeg sawv cev txhawb nqa tuaj yeem sau cov micropores thiab qhov tsis xws ntawm cov khoom siv thiab txhim kho cov compactness thiab hnav tsis kam ntawm cov khoom. Qhov kev txiav txim ntawm cov khoom siv raw no ua rau cov refractory muaj zog dua cov qauv thiab ua rau lub neej ua haujlwm ntev.
Thib peb, cuam tshuam qhov hnav tsis kam ntawm cov ntaub ntawv refractory, txhim kho kev siv cov nyhuv
Cov ntaub ntawv refractory feem ntau raug hnav thiab yaig nyob rau hauv cov txheej txheem kub, yog li kev xaiv thiab sib piv ntawm cov khoom siv raw khoom muaj qhov cuam tshuam tseem ceeb rau nws cov hnav tsis kam. Cov yam ntxwv xws li particle puab, hardness thiab particle loj tis nyob rau hauv raw cov ntaub ntawv txiav txim siab hnav tsis kam ntawm refractory ntaub ntawv. Tsim nyog xaiv cov khoom siv raw thiab tswj cov khoom siv raw piv tuaj yeem txhim kho qhov hnav tsis kam ntawm cov ntaub ntawv refractory, txo qis hnav thiab yaig, thiab txhim kho kev siv cov nyhuv.
Plaub, cuam tshuam cov thermal conductivity ntawm cov ntaub ntawv refractory, optimize cov txheej txheem efficiency
Lub thermal conductivity ntawm refractory raw cov ntaub ntawv muaj ib qho tseem ceeb ntawm cov efficiency thiab lub zog noj ntawm kub txheej txheem. Lub thermal conductivity nruab nrab thiab thermal conductivity muab tub lim nyob rau hauv cov khoom siv raw tuaj yeem txhim kho cov thermal conductivity ntawm refractory thiab txhim kho cov thermal conduction efficiency. Optimizing thermal conductivity ntawm refractory tuaj yeem ua kom cov cua sov hloov mus, txhim kho cov txheej txheem kev ua haujlwm thiab txo kev siv hluav taws xob.
Refractory raw cov ntaub ntawv ua lub luag haujlwm tseem ceeb hauv kev kub siab ua haujlwm, lub zog muaj zog, hnav tsis kam thiab thermal conductivity. Los ntawm kev xaiv tsim nyog ntawm cov khoom siv raw thiab kev ua kom zoo ntawm qhov sib piv, nws tuaj yeem muab kev kub siab ua haujlwm, txhim kho cov txheej txheem lub zog ntawm refractories, txhim kho cov hnav tsis kam ntawm refractories thiab optimize cov txheej txheem efficiency. Nyob rau hauv lub neej yav tom ntej txoj kev loj hlob, kev tshawb fawb thiab daim ntawv thov ntawm refractory raw cov ntaub ntawv yuav txuas ntxiv mus txhawb txoj kev loj hlob ntawm refractory technology kom tau raws li qhov kev hloov pauv ntawm cov txheej txheem kub.
