Nqa cov cib ua pa Piv txwv li, luv luv piav qhia txog kev paub txog cov khoom siv refractory

Rau cov tuam txhab steel thiab cov khoom siv refractory kev lag luam, cov cib ua pa yog qhov tseem ceeb heev thiab cov khoom siv refractory ntau; Ua ib qho piv txwv, tsab xov xwm no tham txog cov ntaub ntawv refractory los ntawm plaub yam ntawm thermal conductivity, tshwj xeeb kub muaj peev xwm, refractoriness, thiab load softening kub. Kev paub yooj yim.

(Daim duab) Refractory

Thermal conductivity ntawm cov ntaub ntawv refractory: Thermal conductivity qhia cov thermal conductivity ntawm ib yam khoom. Qhov ntau dua qhov thermal conductivity, qhov zoo dua thermal conductor. Qhov ntom ntawm ladle air-permeable bricks yog loj dua, thiab thermal conductivity yog correspondingly loj.

Lub peev xwm tshwj xeeb kub ntawm cov ntaub ntawv refractory: Cov peev txheej kub tshwj xeeb sawv cev rau qhov nqus cua sov lossis lub peev xwm ua kom sov ntawm cov khoom. Qhov loj dua qhov tshwj xeeb cua sov muaj peev xwm, qhov muaj zog dua qhov sib piv cov cua sov los yog cov cua kub dissipation muaj peev xwm. Qhov tshwj xeeb kub muaj peev xwm ntawm ventilated bricks muaj feem xyuam rau nws lub sij hawm ci thiab txias.

Refractoriness ntawm cov ntaub ntawv refractory: Raws li tau hais nyob rau hauv tsab xov xwm dhau los, nws yog ib qho kev qhia uas ua ke cov tshuaj muaj pes tsawg leeg, dispersion, kev faib ua feem thiab viscosity ntawm cov kua theem muaj nyob rau hauv cov khoom. Refractoriness yog ib qho tseem ceeb ntawm cov khoom siv refractory. Cov ntaub ntawv refractory yuav tsum muaj peev xwm tiv taus qhov kub siab ntawm kev siv scene thaum siv; rau ventilating bricks, yog hais tias qhov kub ntawm cov hlau molten yog siab dhau lawm, nws yuav tsis tsuas cuam tshuam lub neej ntawm cov ventilating bricks, tab sis kuj ua rau loj leaks, thiab lwm yam kev huam yuaj.

Lub load softening kub ntawm cov khoom siv refractory: Nws qhia txog qhov tsis kam ntawm cov khoom mus rau qhov kub thiab txias thiab thauj khoom tib lub sijhawm. Cov khoom siv refractory muaj lub zog compressive siab ntawm chav tsev kub, tab sis tom qab thauj khoom ntawm qhov kub thiab txias, lawv yuav deform thiab txo lawv lub zog compressive.
