Tsis zoo li refractory
Qhov sib koom ntawm amorphous refractories nyob rau hauv lub ntiaj teb no' s tag nrho cov khoom refractory txuas ntxiv nce.Cov qauv no feem ntau cuam tshuam nrog kev txhim kho cov khoom tshiab thiab kev qhia txog kev tsim kho tshiab.
kwv yees hais tias lub ntiaj teb no tso zis ntawm refractories tau mus txog 45 × 106t ib xyoo. Raws li cov ntaub ntawv ntawm Refractory Industry Association, nyob rau hauv 2019, Tuam Tshoj tus refractory tso zis yog 24.308 lab tons, thiab cov zis nyob rau hauv 2020 yog 24.78 lab tons, ib xyoo-rau-xyoo nce ntawm 1.94%.
Nyob rau hauv thawj ib nrab ntawm 2021, lub teb chaws tso zis ntawm cov khoom refractory yog 12.921,800 tons, ib xyoo-rau-xyoo nce ntawm 4.29%. Ntawm lawv, tuab zoo li tus refractory khoom tau 7.104.600 tons, ib xyoos-on-xyoo nce ntawm 3,64%; thermal rwb thaiv tsev refractory khoom yog 294,100 tons, ib xyoo-rau-xyoo txo ntawm 5.46%; unshaped refractory khoom yog 5.5232 lab tons, ib xyoo-rau-xyoo nce ntawm 5.72%.
Xyoo 2021, kev lag luam steel tseem yuav yog lub khw tseem ceeb rau cov khoom siv refractory. Nyob rau hauv 15 xyoo dhau los, lub ntiaj teb no' s crude steel tso zis tau ob npaug, mus txog 1623 × 106t nyob rau hauv 2015, uas muaj li ntawm 50% yog tsim nyob rau hauv Tuam Tshoj.Nyob rau hauv ob peb xyoos tom ntej no, kev loj hlob ntawm cement, ceramics. thiab lwm yam khoom siv ntxhia yuav ua kom tiav qhov kev loj hlob no.Ntxiv mus, nws tau kwv yees tias qhov nce ntawm cov khoom siv refractory siv hauv kev tsim cov hlau thiab cov khoom tsis yog hlau ntxhia yuav ua kom muaj kev lag luam loj hlob ntxiv. Ntawm qhov tod tes, kev noj cov khoom siv refractory hauv tag nrho cov cheeb tsam tseem txo qis. Txij li thaum xyoo 1970s lig, daim ntawv thov cov pa roj carbon monoxide tau dhau los ua qhov tseem ceeb.Unburned carbon-muaj cib tau siv dav hauv cov hlau thiab steelmaking nkoj kom txo tau cov khoom siv hluav taws xob. carbon refractory bricks.Unshaped refractory cov ntaub ntawv, xws li castables thiab sprayed cov ntaub ntawv, tsis yog tsuas yog kev txhim kho ntawm cov khoom nws tus kheej, tab sis kuj yog kev txhim kho ntawm txoj kev tsim kho.Unshaped refractory linings yuav tsim sai dua li cov khoom zoo li tus, txo cov downtime ntawm lub kiln thiab ho txo cov nqi.
Unshaped refractories account rau 50% ntawm lub ntiaj teb no kev ua lag luam, tshwj xeeb tshaj yog cov kev loj hlob prospects ntawm castables thiab preforms.In Nyiv, raws li ib tug kev qhia rau lub ntiaj teb no qauv, monolithic refractories accounted rau 70% ntawm tag nrho cov refractory ntau lawm nyob rau hauv 2012.
