Lub rooj vag swb teeb ua cov ntaub ntawv tseem ceeb rau cov hlau smelting rauv, ua lub luag haujlwm tseem ceeb hauv tag nrho cov txheej txheem steel smelting
Tsis ntev los no, kom tau txais kev nkag siab zoo thiab kev nkag siab ntawm lub rooj vag swb, txhawm rau pab muab cov kev daws teeb meem zoo tshaj plaws rau cov neeg siv khoom, peb pib ua haujlwm kev cob qhia ntawm cov khoom zoo li no. Hais txog kev txhim kho, cov txheej txheem tsim khoom, cov txheej txheem tseem ceeb, yam cuam tshuam rau lub neej kev pabcuam thiab lwm yam, peb tau caw tus kws tshaj lij engineer. Han piav qhia txhua yam.
Lub rooj vag swb feem ntau yog hais txog tag nrho cov txheej txheem refractories los ntawm lub ladle mus rau tundish thaum lub sij hawm steel casting, nrog rau sab sauv nozzle, sab sauv rooj vag phaj, sab swb rooj vag phaj, qis nozzle / collector nozzle. Upper nozzle yog tsau rau hauv qhov zoo thaiv hauv qab ntawm lub ladle, thiab lub nozzle qis yog txuas nrog ladle shroud. Nyob rau hauv no txoj kev, molten hlau yog tiv thaiv cam khwb cia los ntawm ladle mus rau tundish.
Xyoo 1990s, cov khoom siv rau cov rooj vag swb yog feem ntau corundum; Txhawm rau txhim kho cov thermal poob siab thiab pab ua haujlwm zoo, graphite yog siv rau hauv cov khoom, nrog Phenolic Resin ua tus neeg sawv cev. Nrog rau kev txhim kho ntawm qib steel, thov kom swb rooj vag teeb kuj siab dua. Txhawm rau txhim kho lub zog ntawm cov khoom, zirconia ntxiv. Txog tam sim no, alumina-carbon hom thiab alumina-zirconia-carbon hom feem ntau siv. Rau qee qhov muaj peev xwm loj tshaj 200 tons, loj raug rho tawm haujlwm alumina-carbon swb rooj teeb raug siv. Tsis tas li ntawd, hom spinel thiab hom magnesia kuj tau siv los ntawm qee lub tuam txhab tshwj xeeb.
Lub rooj vag swb yog cov khoom siv, kev pab cuam lub neej rau cov rooj vag swb thiab cov nozzles qis feem ntau yog 1-4 heats; kev pab cuam lub neej ntawm sab sauv nozzles siab dua, nws tau hloov ua ke nrog cov rooj zaum thaiv thiab purging plug. Dhau li ntawm qhov zoo ntawm cov khoom, cov kev ua haujlwm tseem cuam tshuam rau lub neej kev pab cuam ntau, suav nrog: qib steel, refining slag, smelting lub sij hawm, tapping kub, ladle muaj peev xwm, tapping ceev / tus nqi, kev khiav hauj lwm ntawm swb rooj vag txhawb mechanism, tej neeg ua hauj lwm los yog tsis thiab lwm yam .
Ntev Keter muab ntau yam swb rooj vag teeb, thiab tuaj yeem hloov kho rau cov txheej txheem xws li Daniel, CONCAST, Vesuvius, Krosaki thiab lwm yam, nrog rau hom HO, 1 QC, 2QC, 4200, 6300 thiab lwm yam.
Ntev Keter ib txwm mob siab rau ua qhov kev daws teeb meem sab saum toj thiab cov khoom lag luam rau molten steel tswj refractories!
