Muaj pes tsawg hom refractory muaj?
Insulating refractories tuaj yeem raug cais ntxiv rau plaub yam: Cov ntaub ntawv kub-resistant insulating nrog daim ntawv thov kub ≤ 1100 ° C. Refractory insulating cov ntaub ntawv nrog cov ntawv thov kub ≤ 1400 ° C. High refractory insulating cov ntaub ntawv nrog daim ntawv thov kub ≤ 1700 ° C.
Peb qhov kev faib tawm ntawm cov refractories yog dab tsi?
Raws li qhov kev faib tawm no, refractories yog peb hom xws li (i) acid refractories, (ii) yooj yim refractories, thiab (iii) nruab nrab refractories. Kuj tseem muaj qee yam tshwj xeeb ntawm refractories. Acid refractories - Cov refractories no raug tawm tsam los ntawm alkalis (cov slags yooj yim).
Dab tsi yog qhov yooj yim refractories?
Basic refractories muaj ntawm cov zaub mov xws li txiv qaub (CaO) thiab magnesia (MgO)thiab tuaj yeem siv rau hauv ib puag ncig zoo li ib puag ncig. Neutral refractories feem ntau muaj ntau yam sib txawv ntawm chrome nyob rau hauv ob peb daim ntawv ua ke nrog alumina los yog magnesia thiab ua hauj lwm zoo nyob rau hauv nruab nrab ntawm cov kua qaub / puag spectrum.
yog dab tsirefractories siv rau?
Hluav taws kub av nplaum refractories: Lawv feem ntau tau siv los ntawm steel industries. Lawv yog dav siv nyob rau hauv foundries thiab. Magnesium Refractories: Feem ntau yog siv hauv kev lag luam steel rau hauv ob sab phlu ntawm cov converters yooj yim thiab qhib-hearth furnaces. Dolomite refractory: feem ntau siv los kho cov khoom siv.
