Khoom piav qhia
High aluminium hnyav hluav taws kub cib yog cov khoom ntawm kub forging thiab hlawv, cov txheej txheem no tau muab faib ua ob peb theem, qhov tseem ceeb yog kev tshem tawm cov dej thiab kev sib cais ntawm hydrochemical qauv dej ntawm 500 degree C hauv qhov cub, thiab qhov kub tuaj yeem yuav ceev. Thaum lub sij hawm 500-1200 degree, cov nyhuv fusion ntawm cov tshuaj tua kab mob tau ploj mus, thiab cov qib siab ua kua theem tsis tau hloov mus rau hauv, thiab qhov tawg ntawm lub cev yog tsawg. Nyob rau ntawm 1200-1400 degree, cov theem cov tshuaj tiv thaiv yog generated, ua kua sib tov hloov, thiab cov khoom raug rho tawm haujlwm thiab tsim, tab sis cov tawg ntawm lub billet tseem tsawg, thiab qhov kub nce ceev ceev heev. Thaum cov hlau nplaum tau ua tiav thiab tawv tawv ntawm li 1400 degree, nws yuav tsim cov yas deformation thiab cov duab, lub sijhawm no, qhov tawg yog qhov tsawg, lub qhov cub tsis txhob cuam tshuam cov nplaim taws, thiab qhov kub ntawm qhov cub qeeb. Ntawm 1500-1600 degree, cov khoom seem yog calcined..
Qhov zoo ntawm superior av nplaum firebrick
Los ntawm qhov kev xav ntawm Hnyav luag hauj lwm hluav taws cib, yog tias cov ntsiab lus txhuas ntau tshaj 48%, lawv tuaj yeem hu ua aluminium cib siab. Kuj tseem muaj cov aluminium cib siab nrog cov ntsiab lus txhuas sib txawv ntawm 55%, 65%, 75%, 80%, thiab 85%, uas tuaj yeem siv rau hauv qhov cub hauv ob sab phlu ntawm qhov sib txawv.
