Corundum silicon carbide castable yog qhov sib tov ua los ntawm fused xim av corundum thiab silicate alaas binder, thiab ntxiv cov khoom noj xws li kyanite thiab tawg-pov thawj fiber ntau. Nws yog lub Castable Amorphous Refractory cov khoom siv.
Cov yam ntxwv thiab kev thov ntawm Corundum Silicon Carbide castables
Cov yam ntxwv ntawm cov ntaub ntawv raw ntawm Corundum Silicon Carbide Cuzetables:
Cov ntaub ntawv raw ntawm fused xim av corundum thiab silicon carbide yog ntom, siab hardness, siab refractory kub, thiab hnav tsis kam. Lawv yog cov zoo-siab kub thiab hnav-resistant raw khoom raw;
Silicon carbide muaj qhov loj thermal conductivity thiab me me thermal nthuav kev coefficiention. Nws yog qhov nyuaj rau kev ua corroded los ntawm Molten Steel los yog swb, muaj cov oxidation oxidation tsis kam, tsis lo rau hlau shrag, thiab yog hnav-resistant. Nws yog cov khoom siv raw zoo uas muaj peev xwm hu ncaj qha rau hlau lossis hlau slag;
Silicon Micropowder yog cov matrix tivthaiv ntawm Corundum silicon carbide casumne. Tom qab qhov kub siab, nws plays lub luag haujlwm hauv kev sib txuas lossis sib sau ua ke thiab ntim cov hws khov thiab ntim tau thiab ntim ze Nws kuj tseem tuaj yeem txhawb nqa Sintering thiab txhim kho lub ntom ntom, lub zog, muaj kev ua tau zoo thiab siv lub cev (casting lub cev); Ntshiab aluminate xis mas yog qhov siab-tiv thaiv cov khoom siv, uas ua rau cov cam chling muaj lub zog txaus thiab kub-kub tiv thaiv ntawm qhov kub. Kyanite yog cov khoom siv nthuav dav, uas nthuav dav hauv ntim ntawm cov khoom siv kub, tiv thaiv kom muaj qhov kub ntawm cov cua kub ntawm Kiln.
Kev tawg-pov thawj fiber ntau yog cov khoom siv ua ke uas tuaj yeem hlawv ntawm tsawg kub. Thaum lub sij hawm ci, capillary pores yog tsim ua ntej dej vapor tsim. Cov dej dej ntws tawm yog tso tawm los ntawm cov hws los tiv thaiv cov kab ntawv los ntawm kev tawg lossis tev vim cua sov tsis sib xws.
Siv ntawm Corundum silicon carbide castables: feem ntau yog siv los ua cov khoom siv hluav taws xob tsis zoo rau cov khoom siv hluav taws xob tsis zoo, thiab cov khoom siv hluav taws xob tsis zoo thiab cov khoom siv hluav taws xob tsis zoo thiab siab thermal conductivity. Nws yog tsuas yog siv los ua cov kab hlau ntawm cov hlau tiaj thiab lub tso tsheb hlau luam Torpedo, thiab cov ntaub ntawv ntawm Iron Ditch. Nws muaj cov yam ntxwv ntawm kev tawm tsam rau kev yaig los ntawm cov hlau, molten tsis kam, zoo oxidation tiv taus kub, thiab tuaj yeem txhim kho lub neej ntawm lub khob.
