Cov neeg siv khoom hauv Columbia tau xaj 128 tons refractory hluav taws kub silica cib
Lub Kaum Ib Hlis. 128 tons refractory hluav taws kub silica cib tau ntim rau xa mus rau cov neeg siv khoom hauv Columbia. High quality refractory hluav taws cib hauv Topower Refractory.
Silica cib yog cov khoom siv refractory nrog SIO2 cov ntsiab lus ntawm ntau dua 92 feem pua. Qhov siab dua SiO2 cov ntsiab lus hauv cov khoom siv silicon, qhov siab dua qhov hluav taws kub ntawm cov khoom, thiab muaj peev xwm tiv taus cov kua qaub.
Silica cib yog ib qho semi-silicon cib ua los ntawm nplooj wax pob zeb ua cov khoom siv tseem ceeb, uas yog siab tshaj 1700 degree C. Lub tshav kub poob siab yog qhov zoo, nws tuaj yeem tiv taus qhov cuam tshuam ntawm cov hlau seem thiab hlau, thiab muaj peev xwm muaj zog. tawm tsam.
Silica cib yog ntau yam hauv cov khoom siv acidic refractory. Lawv muaj peev xwm tiv taus acid residue los yog acid melting kua yaig. Lawv muaj kev tiv thaiv tsis zoo rau alkaline tshuaj yaig, thiab kev nthuav dav coefficient ntawm silicon bricks loj heev. Qhov ntim ntawm qhov ntau ntawm silicon cib saum toj no 300 degree C kom ze rau lub melting point yog ruaj khov. Thaum cua sov mus rau 1450 ° C, 1.5 feem pua rau 2.2 feem pua ntawm qhov ntim yuav raug tsim tawm. Qhov loj tshaj qhov tsis zoo ntawm silica bricks yog tias qhov kub tsis kam tiv thaiv tsis zoo, thiab qhov hluav taws kub tsis zoo (feem ntau 1690 ~ 1730 degree C), thiab nws cov kev siv tau txwv.
Silica cib ua los ntawm wax pob zeb. Micro expansion yuav tshwm sim. Vim tias cov ntxhia pob zeb ntawm cov pob zeb ua kom sov, cov qauv siv lead ua hauv cov qauv siv lead ua hloov me me, yog li nws shrinks thaum ci, thiab qee zaum nws yuav o me ntsis. Thaum lub sij hawm siv high-temperature siv, nplooj wax thiab acid slag cov tshuaj tiv thaiv yuav tsim ib txheej ntawm viscosity nrog loj viscosity nyob rau saum npoo ntawm semi-silicon cib kom tsis txhob acid slag nkag mus rau hauv lub cib. Lub peev xwm erode kuj zoo heev.
Tus nqi ntawm silica bricks yog loj thiab muaj ntau ntau yam. Nws yog tsuas yog siv nyob rau hauv chav tsev carbonization, combustion chav thiab muab faib phab ntsa ntawm lub coke cub, thiab lub kiln saum thiab kiln pas dej ua ke ntawm lub khob pas dej kiln. Kuj tseem muaj qhov cub ntawm qhov kub thiab txias load-bearing qhov chaw, carbon roasting furnaces xws li cua kub rauv, thiab carbon roasted furnaces. Muaj ntau ntau yam ntawm silica cib. Lawv muab faib ua coke furnaces, silicon cib rau cov cua kub qhov cub, silicon cib rau hluav taws xob furnaces, thiab silicon vuas rau iav kiln.
Qhov ntau thiab tsawg ntawm semi-silica cib tsis muaj ntau ntawm silicon cib, uas tsis tshua muaj kev txwv. Txawm hais tias nws tuaj yeem siv rau hauv qab hauv qab ntawm lub hnab steel, sab hauv ntawm lub hnab dej hlau, thiab cov flue, tus nqi ntawm semi-silica cib yog me me.
