Refractory yog dab tsi?
Refractoriesyog cov ntaub ntawv uas muaj peev xwm tiv taus kub, hnav tsis kam, corrosion kuj, tshuaj yaig kuj thiab lwm yam tshwj xeeb ib puag ncig. Lawv tau siv dav hauv metallurgy, tshuaj lom neeg kev lag luam, kev tsim kho, lub zog thiab lwm yam kev lag luam, thiab yog cov khoom siv tseem ceeb hauv cov kev lag luam no.
Muaj ntau ntau hom refractories, raws li lawv cov khoom sib txawv, tuaj yeem muab faib ua inorganic refractories thiab organic refractories ob pawg. Inorganic refractories feem ntau yog tsim los ntawm alumina, silicate, calcium oxide thiab lwm yam ntaub ntawv, thaum cov organic refractories yog tsim los ntawm cov ntaub ntawv organic polymer. Txawm hais tias inorganic lossis organic refractory cov ntaub ntawv, lawv muaj qhov kub thiab txias tsis kam, hnav tsis kam, corrosion kuj thiab lwm yam ntxwv.
Hauv kev lag luam metallurgical, cov ntaub ntawv refractory tau siv dav hauv cov ntaub ntawv thiab cov phab ntsa ntawm lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob, lub tshuab hloov hluav taws xob, lub tshuab hluav taws xob, lub tshuab hluav taws xob kub thiab lwm yam khoom siv. Cov khoom siv no ua haujlwm ntawm qhov kub txog li 1000 ° C lossis ntau dua, xav tau cov refractories kom muaj qhov kub thiab txias heev. Nyob rau tib lub sijhawm, kev lag luam metallurgical kuj xav tau refractories nrog zoo oxidation tsis kam mus rau kev pab cuam lub neej ntawm cov khoom siv.
Hauv kev lag luam tshuaj, cov ntaub ntawv refractory feem ntau yog siv rau hauv ob sab phlu thiab cov phab ntsa ntawm cov reactors, kilns, chimneys thiab lwm yam khoom siv. Ntau cov txheej txheem hauv kev lag luam chemical yuav tsum tau nqa tawm ntawm qhov kub thiab txias, thiab qhov yuav tsum tau ua rau refractories siab heev. Nyob rau tib lub sijhawm, kev lag luam tshuaj lom neeg kuj xav tau cov refractories nrog corrosion kuj zoo los tiv thaiv kev yaig ntawm cov tshuaj lom neeg.
Hauv kev tsim kho kev lag luam, cov khoom siv refractory feem ntau yog siv rau hauv tsev rwb thaiv tsev, tiv thaiv hluav taws thiab lwm yam. Nrog rau kev nrawm ntawm cov txheej txheem hauv nroog, kev tsim cov tsev siab siab ntau dua, thiab cov kev xav tau ntawm cov khoom siv hauv tsev kuj yog siab dua thiab siab dua. Cov khoom siv hluav taws xob muaj hluav taws kub zoo thiab tuaj yeem tiv thaiv kev nyab xeeb ntawm cov tsev.
Hauv luv luv, refractories ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam. Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, cov hom refractories kuj nce ntxiv, thiab kev ua tau zoo kuj tseem txhim kho. Nws ntseeg tias yav tom ntej kev txhim kho,refractorycov ntaub ntawv yuav ua lub luag haujlwm tseem ceeb dua.
