Taw qhia rau cov yam ntxwv ntawm chrome refractory bricks

Chromium refractory cib muaj cov ntsiab lus Cr2O3 siab dua (ntau dua 30%), thaum cov cib refractory nrog cov ntsiab lus tsawg MgO (10 ~ 30%) yog chromium refractory cib.

Nws lub ntsiab yam ntxwv yog hais tias nws yog ib tug nruab nrab refractory khoom. Vim tias Cr2O3 yog qhov nruab nrab oxide, nws muaj kev tiv thaiv zoo rau alkaline slag thiab acid slag. Chrome cib qee zaum siv rau masonry ntawm qhov sib txuas ntawm cov kua qaub refractory cib thiab alkaline refractory cib los tiv thaiv cov tshuaj tiv thaiv ntawm acid refractory cib thiab alkaline refractory cib ntawm qhov kub thiab txias.
