Khoom piav qhia
High-lub luag hauj lwm firebrick yog ib hom ntawm nruab nrab qib hluav taws cib ntawm cov stereotyped khoom ntawm refractory ntaub ntawv. Nws belongs rau nruab nrab cov ntaub ntawv refractory thiab yog siv nyob rau hauv ob sab phlu ntawm industrial kilns.
Muaj ntau Al2O3 nyob rau hauv lub luag hauj lwm siab firebrick aluminium cib, ze rau nruab nrab cov ntaub ntawv refractory, uas muaj peev xwm tiv taus yaig ntawm acidic slag thiab alkaline slag, vim hais tias nws muaj SiO2, yog li lub peev xwm ntawm anti-alkaline slag yog weaker tshaj lub peev xwm ntawm anti- kua qaub slag. Tsis tas li ntawd, cov slag kuj ntawm cov khoom siv aluminium siab kuj tseem cuam tshuam rau kev ruaj ntseg ntawm cov khoom hauv cov slag. Feem ntau, tom qab kev kub siab molding thiab kub kub tua, cov khoom uas muaj porosity qis dua slag kuj.
