Yuav ua li cas txog qhov ua tau zoo ntawm av nplaum refractory bricks?

Av nplaum refractory cib yog cov khoom siv tsis muaj zog acidic refractory, uas tuaj yeem tiv taus qhov yaig ntawm cov kua qaub slag thiab kua qaub roj, thiab muaj qhov tsis zoo rau cov tshuaj alkaline. Cov av nplaum refractory cib muaj cov khoom siv thermal zoo thiab tiv taus qhov txias txias thiab kub ceev.

Qhov hluav taws kub tsis kam ntawm cov av nplaum refractory cib yog sib npaug ntawm cov silica cib, ncav cuag 1690 ~ 1730 ℃, tab sis cov softening kub nyob rau hauv load yog ntau tshaj 200 ℃ qis dua silica bricks. Vim hais tias av nplaum refractory cib tsis tsuas yog muaj mullite crystals nrog siab refractoriness, tab sis kuj muaj ze li ntawm ib nrab ntawm lub amorphous iav theem nrog tsawg melting point.
