Cov cuab yeej kuaj

Peb lub tuam txhab muaj txhua yam ntawm cov cuab yeej kuaj kev tshaj lij

Cold crushing zog (CCS):

Hais txog lub peev xwm ntawm cov khoom los tiv thaiv sab nraud ntawm chav tsev kub.Yog hais tias lub refractory tsis muaj zog txaus, nws lub peev xwm los tiv thaiv sab nraud mechanical kev nyuaj siab yog txo, uas yuav ua rau tawg thaum siv thiab masonry.

Modulus ntawm rupture (MOR):

Qhia txog lub peev xwm ntawm cov khoom los tiv thaiv kev khoov.Muab cov qauv tso rau ntawm qhov kev txhawb nqa thiab thauj khoom ntawm ib tus nqi kom txog rau thaum qhov nruab nrab ntawm cov qauv tawg.Tom qab ntawd lub zog flexural yog xam los ntawm qhov ntev ntawm lub bracket;lub load thiab qhov chaw hla ntu ntawm cov qauv thaum nws tawg.

Pom tseeb porosity

Nws hais txog qhov feem pua ​​​​ntawm qhov ntim ntawm qhov qhib pores hauv cov khoom refractory rau tag nrho cov ntim ntawm cov khoom.Rau cov ntaub ntawv ntom ntom, qhov qis ntawm qhov pores, qhov zoo dua qhov ntom.Nyob rau tib lub sijhawm, cov cib uas tsis muaj porosity kuj tseem tuaj yeem tiv thaiv kev nkag mus ntawm cov pa phem thaum siv.

Refractoriness nyob rau hauv load (RUL)

Qhia qhov kev ntxhov siab kawg ntawm cov khoom tiv thaiv kev khoov ntawm qhov kub thiab txias, feem ntau yog teem rau ntawm 1000 ° C;1200 ° C thiab 1400 ° C.Muab cov qauv tso rau ntawm qhov kev txhawb nqa thiab thauj khoom ntawm ib tus nqi kom txog rau thaum qhov nruab nrab ntawm cov qauv tawg.Tom qab ntawd lub zog flexural yog xam los ntawm qhov ntev ntawm lub bracket;lub load thiab qhov chaw hla ntu ntawm cov qauv thaum nws tawg.

Hais txog qhov deformation ntawm tuab cov ntaub ntawv refractory raws li qhov kub nce qis nyob rau hauv qee yam kev thauj khoom.Qhov ntsuas kub siab tshaj plaws yog 1700 ° C.Qhov siab dua qhov chaw thau khoom, qhov muaj peev xwm tiv taus qhov kub thiab txias.

Thermal shock resistance (TSR):

Hais txog qhov nro tshwm sim los ntawm kev hloov pauv loj hauv qhov kub thiab txias, uas ua rau tawg lossis tawg ntawm cov khoom siv, tshwj xeeb tshaj yog rau cov ntaub ntawv nkig.Cov ntaub ntawv refractory yuav tsum muaj qhov toughness txaus los tiv thaiv qhov hloov pauv hauv cov kiln ntawm qhov kub thiab txias.Yog hais tias lub toughness tsis txaus, cov khoom yuav tawg los yog headshot.
