Taw qhia rau Refractories

Ib chav kawm ntawm inorganic non-metallic cov ntaub ntawv nrog lub refractoriness tsis qis dua 1580 degree. Refractoriness yog hais txog qhov kub ntawm Celsius uas tus qauv refractory conical tuaj yeem tiv taus kub yam tsis muaj softening thiab melting yam tsis muaj load. Txawm li cas los xij, nws tsis tuaj yeem piav qhia tag nrho cov ntaub ntawv refractory tsuas yog los ntawm lub ntsiab lus ntawm refractoriness, thiab 1580 degree tsis yog kiag li. Nws yog tam sim no txhais tau tias yog ib yam khoom uas nws lub cev thiab tshuaj muaj zog tso cai rau nws siv nyob rau hauv ib tug kub kub ib puag ncig yog hu ua ib tug refractory khoom. Cov ntaub ntawv refractory yog siv dav hauv metallurgy, tshuaj lom neeg kev lag luam, roj av, tshuab tsim, silicate, fais fab thiab lwm yam kev lag luam, thiab siv ntau tshaj plaws hauv kev lag luam metallurgical, suav txog 50% mus rau 60 feem pua ​​​​ntawm tag nrho cov zis.
