Kev ntws tawm tus kheej yog cov qauv kev ua haujlwm tshiab refractives tsim muaj 10 xyoo dhau los. Lawv muaj lub hauv paus ntawm cov khoom siv rov qab ua kom tawg thiab tsim tawm ntawm cov qauv zoo nkauj uas muaj kev sib tham zoo. Qhov no koj tus kheej khiav yog siv nyob rau hauv cov khoom siv thermal xws li nyias cov kab ntawv, nyuaj rau tsim lossis kho cov kab, thiab muaj cov txiaj ntsig kev lag luam tseem ceeb. Nyob rau tib lub sijhawm, nws tau raug thov rau cov khoom siv thermal xws li cov ntaiv, tawg paj rauv, cua sov cov lus cog thiab cov txiaj ntsig cua sov thiab ua tiav cov txiaj ntsig zoo.
Kev ntws tawm tus kheej (SFC) muaj cov khoom siv sib xyaw ua ke Nws cov yam ntxwv yog: kev ua yeeb yam ntawm cov Castable zoo ib yam li lossis me ntsis zoo dua li ntawm hom qis gras series refractory casableable; Tsis tas yuav tsum muaj cov khoom siv uas yuav tsum tau ua tiav, thiab tsis muaj cov kab hlau ntxeem tau, yog li nws tuaj yeem txo cov nqi tsim kho, yog li kev siv qias neeg; Cov khoom siv matrix ntawm lubast yog ntawm cov khoom lag luam zoo thiab muaj ntau yam muaj nuj nqis yuav tsum tau ua kom haum cov khoom siv tus kheej, yog li kev tso pa tawm, tab sis tus nqi ntawm cov ntaub ntawv raw yog nce me ntsis.
Hauv kev ua kom tus kheej kev ua kom txaus siab, kom tau txais cov fluidity uas tsim nyog, nws yog qhov tsim nyog xaiv ntau yam thiab ntau npaum li cas ntawm cov hmoov pob txha refractory thiab binder. Nyob rau tib lub sijhawm, txhawm rau txo cov dej, nws tseem yog ib qho tseem ceeb heev ntxiv rau cov roj reducer ntxiv.
Thaum npaj tus kheej cov khoom siv tus kheej, hom ntawm dej reducer yuav tsum tau xaiv raws li cov yam ntxwv ntawm cov khoom siv hluav taws xob, tshwj xeeb yog cov khoom siv matrix zoo tshaj plaws, thiab nws yog qhov zoo tshaj plaws los siv lawv ua ke.
Daim ntawv thov tseem ceeb ntawm kev siv tus kheej yog qhov nqaim ntawm lub cub thiab kho cov kab mob puas tuaj yeem qhia tau meej. Thaum npaj tus kheej cov khoom siv ua kom zoo, cov ntaub ntawv nrog cov tuab tuab, cov dej nqus dej siab thiab ob peb impurities yuav tsum tau xaiv raws li refractory aggregates.
