Cov cement rotary kiln yog cov khoom siv tseem ceeb hauv kev tsim cov cement. Txhawm rau kom ntseeg tau tias nws ua haujlwm tau zoo thiab ruaj khov mus ntev, kev xaiv cov khoom siv refractory tsim nyog yog qhov tseem ceeb. Cov nram qab no yog cov refractory cib feem ntau siv hauv cov cement rotary kilns. Koj puas paub lawv tag nrho?
1. Phosphate bonded siab alumina hauv ob sab phlu
Phosphate bonded siab alumina hauv ob sab cib muaj xws li phosphate bonded siab alumina cib (hu ua phosphate cib), thiab phosphate bonded siab alumina hnav-resistant cib (xa mus rau hnav-resistant bricks).
2.Magnesia refractory cib
Lub cib cov ntsiab lus magnesium oxide tsis tsawg dua 91%, calcium oxide cov ntsiab lus tsis ntau tshaj 3%, thiab nws yog ib qho khoom alkaline refractory nrog periclase ua cov ntxhia tseem ceeb.
3. Magnesia-aluminium spinel cib
Magnesia-alumina spinel refractory cib yog magnesia cib tsim nrog magnesium-alumina spinel ua cov pob zeb tseem ceeb los ntawm kev ntxiv alumina rau cov khoom xyaw txhawm rau txhim kho thermal shock stability ntawm magnesia cib.
4. ncaj qha muab cov magnesia chrome cib
Hauv cov kiln loj, thaum lub qhov cub kub siab tshaj 1700 degree, zoo tib yam magnesia-chromium refractory bricks tsis muaj peev xwm. Kev sib xyaw ua ke ncaj qha ntawm magnesia-chromium cib yog tsim los hloov mus rau qhov loj-scale cement ntau lawm - high-zoo magnesia-chromium refractory cov ntaub ntawv.
5. Ordinary magnesia chrome cib
Magnesia chrome cib muaj MgO55%-80%, Cr2O3 Ntau dua lossis sib npaug li 8%, cov zaub mov tseem ceeb yog periclase thiab chromium spinel, thiab theem silicate yog forsterite thiab forsterite.
6. Sodium polyphosphate bonded magnesia cib
Lub cib no yog cov tshuaj sib xyaw ua ke magnesia cib, uas siv high-calcium synthetic magnesia li aggregate, sodium polyphosphate li binder, thiab pulp pov tseg kua li hydration inhibitor.
7.Alkali-resistant bricks
Nws yog alkali-resistant av nplaum refractory cib nrog cov ntsiab lus Al2O3 ntawm 25-28%. Cov alkali nyob rau hauv lub kiln gas condenses ntawm lub cib nto thiab sai sai reacts chemically nrog lub cib nto los ua ib tug high-viscosity glaze txheej, uas seals lub alkali los ntawm nkag mus rau hauv lub cib lub cev. Cov pores txuas ntxiv mus, yog li tiv thaiv "alkali cracking".
8. High alumina cib
High alumina cib yog aluminium silicate refractory khoom nrog cov ntsiab lus alumina ntau dua 48%.
Ntxiv nrog rau cov cib refractory, cov cement kilns kuj siv lwm cov khoom siv refractory, cov khoom siv refractory castables, rwb thaiv tsev thiab cov khoom siv hluav taws xob, thiab lwm yam, uas Topower tuaj yeem muab tau. Peb kuj tos ntsoov yuav koom tes nrog koj.
