Refractoriness yog ib qho tseem ceeb qhia txog qhov zoo ntawm refractory cib. Nws yog ncaj qha ntsig txog cov tshuaj ntxhia hauv cov khoom siv raw. Yog tias muaj ntau yam khoom siv raw siv rau hauv cov khoom xyaw ntawm refractory bricks, yuav tsum tau them nyiaj mloog mus rau lub purity ntawm raw cov ntaub ntawv thiab lawv cov kev sib nrig sib zog. Feem ntau, qhov kev ua tau zoo ntawm cov av nplaum clinker los yog cov av nplaum uas tsis muaj zog (cov av nplaum tawv nrog me me shrinkage), uas suav nrog cov nyiaj tseem ceeb hauv cov khoom xyaw av nplaum, txiav txim siab qhov zoo ntawm sk34 refractory cib. Cov av nplaum (muab, av nplaum) siv los ua kev sib xyaw ua ke feem ntau yog cov khoom siv raw nrog loj shrinkage thiab tsis tshua muaj refractoriness. Yog tias qhov nyiaj ntau dhau lawm, qhov kev ua tau zoo ntawm cov clinker lossis cov av nplaum barren yuav raug txo kom tsawg. Thaum ua cov silica bricks, quartz xuab zeb yog Ameslikas raw khoom nrog siab refractoriness, tab sis vim hais tias ib feem ntawm cov av nplaum yog ntxiv raws li ib tug binder, thiab cov refractoriness ntawm xws li av nplaum tej zaum yuav tsawg, lub refractoriness ntawm cov khoom yuav tsum tsawg tshaj li ntawm. quartz xuab zeb nws tus kheej. Yog li, nws tuaj yeem hais tias cov tshuaj ntxhia hauv cov khoom xyaw txiav txim siab qhov kev ua tau zoo ntawm sk34 refractory cib.
Nws yuav tsum tau taw qhia tias qhov refractoriness ntawm sk34 refractory bricks tsuas yog ib qho ntawm cov cim tseem ceeb los ntsuas nws qhov zoo. Raws li kev siv zoo ntawm refractory bricks, nws yuav tsum tau tswj nyob rau hauv ua ke nrog nrog rau cov txheej txheem tsim, uas yog, seb cov tsos thiab sab hauv ntawm sk34 refractory bricks yog ntom. Cov no muaj feem xyuam nrog cov yam xws li kev sib koom ua ke ntawm cov khoom xyaw, qhov loj ntawm lub siab molding, thiab seb lub adobe yog siav los yog overfired. Yog hais tias lub refractoriness ntawm sk34 refractory cib cov khoom xyaw yog siab heev (txawm hais tias saum toj no 1700 degree), tab sis lub adobe tsis nruj nreem packed thiab tsis tau sintered (xoos), nws cov kev pab cuam lub neej yuav tsum luv luv, vim hais tias hom no sk34 refractory cib. muaj porosity loj thiab lub zog. Tsis zoo, yooj yim corroded los ntawm teeb meem kua los yog roj thaum siv. Yog li ntawd, thaum txiav txim siab seb qhov hluav taws kub refractory cib yog qhov zoo los yog phem (tshwj xeeb yog qhov zoo ntawm kev siv), nws yuav tsum tau txiav txim siab. Lub refractoriness Performance index tsuas yog thawj lub hauv paus rau cov ntaub ntawv koom nrog.
Raws li tau hais los saum toj no, txhawm rau ntsuas qhov refractoriness ntawm tus qauv yog coj lub beech los ntawm lub xeem daim, grind nws los ua ib tug daim duab peb sab pyramid nrog ib tug tshwj xeeb cov duab, thiab ces ntsuas lub ntuj melting kub ntawm daim duab peb sab pyramid nyob rau hauv lub cub hluav taws xob raws li ib tug tshwm sim. qauv index ntawm refractoriness. Qhov teeb meem no tsis sib haum nrog cov kev siv tiag tiag ntawm sk34 refractory bricks. Feem ntau, tom qab cov hluav taws kub refractory bricks tau tsim rau hauv phab ntsa, cov cib qis tshaj yog raug rau ob qho tib si kub thiab siab siab (cov cib hauv qab kuj tseem eroded los ntawm smelting hlau tov), thiab lub siab los yog sab nraud impulse kuj txo cov refractoriness. ntawm cov ntaub ntawv refractory (lub refractoriness nyob rau hauv ib lub siab yog hu ua lub load softening kub). Yog li ntawd, lub refractoriness tsis qhia qhov kub ntawm qhov refractory hluav taws cib siv tau. Rau kev nyab xeeb kev ua haujlwm, qhov kev pabcuam kub ntawm cov hluav taws kub nyhiab yog li ntawm 200-250 degree qis dua nws qhov ntsuas refractoriness.
