Yuav ua li cas xaiv ramming khoom rau melting cam khwb cia hlau nyob rau hauv induction rauv?
Cam khwb cia hlau induction furnaces yog lined nrog refractory cov ntaub ntawv nyob rau hauv lub cub tawg phab ntsa, thiab acidic quartz ramming ntaub ntawv feem ntau yog siv. Tam sim no, feem ntau foundries siv pheej yig ntuj quartz induction rauv ramming cov ntaub ntawv. Txawm hais tias ntuj quartz yuav nthuav dav vim yog crystalline transformation ntawm si thaum siv, crystalline transformation ntawm quartz yog irreversible thiab yuav nyob twj ywm thaum txias. Yog li ntawd, qhov kub ntawm lub qhov cub phab ntsa hauv ob sab phlu tsis yooj yim rau cov kab nrib pleb, thiab lub neej ruaj khov thiab txhim khu kev qha tuaj yeem tau txais. Txawm li cas los xij, vim qhov loj thermal expansion coefficient ntawm si, thermal shock kuj tsis zoo. Nws yog qhov yuav tsum tau ua kom lub qhov cub induction tsis tuaj yeem nqus tau thaum siv. Kev ua haujlwm tsis tu ncua yog qhov zoo tagnrho. Tam sim no, lub neej kev pab cuam ntawm lub tshuab hluav taws xob hauv tsev hauv ob sab phlu rau nruam melting ntawm cam khwb cia hlau nrog lub peev xwm ntau dua 10t yog 40 mus rau 90 hnub, thiab lub neej kev pab cuam ntawm lub cub tawg phab ntsa ntawm lub qhov cub induction nrog lub peev xwm me me yuav ntev dua. .
