Refractory yog dab tsi

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