Cov khoom siv refractory uas tiv taus hnav yog ib hom khoom siv refractory amorphous uas siv dav hauv metallurgy, petrochemicals, cov ntaub ntawv tsim kho, fais fab thiab lwm yam lag luam. Cov khoom siv no muaj qhov zoo ntawm kev tiv taus kub siab, tiv taus hnav, thiab tiv taus kev yaig. Nws yog siv los kho thiab tiv thaiv cov ntaub ntawm cov khoom siv kub siab xws li lub cub tawg thiab lub boiler kom ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua.

7. Lub lauj kaub castable:Ladle castable yog ib qho amorphous refractory castable ua los ntawm cov khoom zoo siab alumina bauxite clinker thiab silicon carbide ua cov khoom tseem ceeb, nrog rau cov khoom siv aluminate cement binder, dispersant, shrinkage-proof agent, coagulant, explosion-proof fiber thiab lwm yam additives. Vim tias nws muaj cov nyhuv zoo hauv txheej ua haujlwm ntawm lub ladle, nws tseem hu ua txhuas silicon carbide castable.

8. Cov khoom siv hluav taws xob uas tsis hnyav thiab tsis yooj yim tawg:Cov khoom siv hluav taws xob rwb thaiv tsev uas sib dua yog cov khoom siv hluav taws xob rwb thaiv tsev uas muaj qhov hnyav sib dua, muaj zog heev thiab ua tau zoo heev rau kev rwb thaiv tsev kub. Nws feem ntau yog ua los ntawm cov khoom sib xyaw ua ke uas sib dua (xws li perlite, vermiculite, thiab lwm yam), cov khoom siv ruaj khov thaum kub siab, cov khoom sib txuas thiab cov khoom ntxiv. Nws yog siv dav hauv ntau yam khoom siv hauv kev lag luam uas kub siab, xws li cov cub tawg hauv kev lag luam, cov cub tawg kho cua sov, cov cub tawg hlau, cov cub tawg iav yaj, thiab lwm yam, los txhim kho kev siv hluav taws xob ntawm cov khoom siv thiab txo kev siv hluav taws xob.

9. Corundum castable:Nrog nws cov kev ua tau zoo heev, corundum castable tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov khoom tseem ceeb ntawm cov kilns thermal. Cov yam ntxwv ntawm corundum castable yog lub zog siab, qhov kub siab softening thiab zoo slag tsis kam, thiab lwm yam. Qhov kub siv dav dav yog 1500-1800 ℃.

10. Magnesium castable:Feem ntau siv rau hauv cov khoom siv kub thiab txias, nws muaj kev tiv taus zoo heev rau alkaline slag corrosion, qis oxygen potential index thiab tsis muaj kuab paug rau cov hlau molten. Yog li ntawd, nws muaj ntau yam kev siv hauv kev lag luam metallurgical, tshwj xeeb tshaj yog hauv kev tsim cov hlau huv thiab kev lag luam khoom siv hauv tsev.

11. Av nplaum uas siv tau:Cov khoom tseem ceeb yog av nplaum clinker thiab av nplaum sib xyaw, nrog kev ruaj khov zoo thiab qee qhov refractoriness, thiab tus nqi qis dua. Nws feem ntau yog siv rau hauv daim ntaub ntawm cov kilns kev lag luam dav dav, xws li cua sov rauv, annealing rauv, boilers, thiab lwm yam.

12. Cov castable qhuav:Cov castable qhuav feem ntau yog ua los ntawm cov khoom sib xyaw ua ke, hmoov, cov khoom khi thiab dej. Cov khoom xyaw feem ntau suav nrog av nplaum clinker, tertiary alumina clinker, hmoov zoo heev, CA-50 cement, cov tshuaj dispersants thiab cov tshuaj siliceous lossis feldspar impermeable agents.

Cov castable qhuav muaj peev xwm muab faib ua ntau hom raws li lawv siv thiab cov khoom xyaw. Piv txwv li, cov castable qhuav impermeable feem ntau yog siv rau hauv cov hlwb electrolytic txhuas, uas tuaj yeem tiv thaiv kev nkag mus ntawm electrolytes thiab ntev lub neej kev pabcuam ntawm cov hlwb. Tsis tas li ntawd, cov castable qhuav refractory yog qhov tsim nyog rau cov khoom siv kho vajtse, smelting, kev lag luam tshuaj lom neeg, cov hlau tsis yog ferrous thiab lwm yam lag luam, tshwj xeeb tshaj yog nyob rau hauv kev lag luam hlau, xws li lub qhov ncauj kiln rotary, lub cub tawg, lub hau kiln thiab lwm yam khoom.
