Hom Magnesia Spinel Cib lossis Magnesia Chrome Cib Puas Tsim Nyog Rau RH Rauv?

MagnesiaHercynite spinel cibthiabmagnesia chrome cibyog cov ntaub ntawv refractory uas feem ntau siv nyob rau hauv rotary kilns thiab lwm yam khoom siv kub kub hauv kev lag luam steel. Txawm li cas los xij, rau RH furnaces (kua steel nqus cov khoom siv kho mob), kev xaiv ntawm cib yuav tsum tau txiav txim siab raws li nws cov kev xav tau tshwj xeeb.

Adaptable kub: Qhov ntsuas kub hloov tau ntawm Magnesia Hercynite Brick yog qis dua, kwv yees li ntawm 1300 degree thiab 1500 degree, thaum qhov hloov pauv kub ntawm magnesia chrome bricks yog siab dua, uas tuaj yeem ncav cuag 1600 degree. Rau RH furnaces, magnesia-chrome cib tej zaum yuav tsim nyog yog tias qhov kev ua haujlwm kub siab dua.

Chemical stability: Magnesia spinel bricks muaj kev tiv thaiv zoo rau tshuaj tua kab mob los ntawm alkaline slag thiab molten steel, thaum magnesia-chrome bricks muaj kev cuam tshuam ntau rau cov teebmeem ntawm cov tshuaj no. Yog li ntawd, yog hais tias RH rauv yuav tsum tau alkaline slag los yog molten steel, magnesia alumina spinel cib yuav tsim nyog.

Mechanical zog: Magnesia-chrome bricks muaj thermal poob siab zoo dua, thaum magnesia-spinel bricks muaj zog hnav tsis kam. Rau RH rauv, nws cov kev ua tau zoo ntawm kev siv tshuab kuj yuav tsum tau muab rau hauv kev txiav txim siab.

Hauv cov ntsiab lus, kev xaiv ntawm magnesia spinel cib los yog magnesia chrome cib nyob ntawm cov xwm txheej tshwj xeeb ntawm RH rauv. Yog tias qhov ua haujlwm kub siab dua thiab cov khoom siv kho tshuab zoo dua yuav tsum tau ua, ces magnesia-chrome cib yuav tsim nyog dua; Yog hais tias tsis kam mus yaig los ntawm alkaline slag los yog molten steel thiab zoo dua hnav kuj yuav tsum tau, ces magnesia alumina spinel cib yuav tsim nyog. Hauv kev siv tswv yim, lwm yam yuav tsum tau xav txog, xws li tus nqi, muaj, thiab lwm yam.
