Khoom Description
Cored hlau yog cov khoom siv tseem ceeb hauv cov txheej txheem steelmaking thiab yog siv dav hauv kev lag luam steel. Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev txhim kho ntawm kev lag luam, hom thiab cov ntsiab lus ntawm cov xov hlau cored tau txuas ntxiv txhim kho thiab txhim kho.
Feem ntau hom cored hlau yog calcium silicon cored hlau. Nws yog tsim los ntawm cov hlau sheath thiab cov khoom ntim, uas yog sib xyaw ntawm silicon hmoov thiab calcium hmoov. Calcium silicon cored hlau yog tsuas yog siv rau deoxidation thiab desulfurization nyob rau hauv cov txheej txheem steelmaking. Nws tuaj yeem txhim kho qhov zoo ntawm cov hlau thiab txo cov impurities hauv cov hlau. Los ntawm kev txhim kho tas mus li, calcium silicon cored hlau tau ua kom ruaj khov thiab ua haujlwm tau zoo.
Lwm hom cored hlau yog carbon cored hlau, uas yog siv los ua kom carbon cov ntsiab lus nyob rau hauv cov txheej txheem steelmaking. Carbon cored hlau yog tsuas yog siv nyob rau hauv zus tau tej cov steel tshwj xeeb, xws li caij nplooj ntoos hlav steel, bearing steel, thiab alloy steel. Los ntawm kev siv cov pa roj carbon cored hlau, cov ntsiab lus carbon hauv cov hlau tuaj yeem raug tswj xyuas kom raug, ua kom muaj kev sib haum xeeb thiab ruaj khov ntawm cov hlau.
Ferrochrome cored hlau kuj yog ib hom kev siv cored hlau. Nws yog tsim los ntawm cov hlau sheath thiab cov khoom ntim, uas yog sib xyaw ntawm ferrochrome hmoov thiab ib qho me me ntawm cov hmoov carbon. Ferrochrome cored hlau yog tsuas yog siv nyob rau hauv cov txheej txheem ntawm stainless hlau thiab lwm yam tshwj xeeb steels. Nws tuaj yeem txhim kho corrosion kuj thiab lwm yam khoom ntawm cov hlau.
Ntxiv nrog rau cov hom kab cored feem ntau siv no, kuj tseem muaj ntau lwm hom cored hlau, xws li txhuas cored hlau, titanium cored hlau, nickel cored hlau, thiab lwm yam. Cov xov hlau cored no muaj lawv tus kheej cov khoom tshwj xeeb thiab siv rau hauv cov txheej txheem ntau lawm los txhim kho qhov zoo ntawm cov hlau.
Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho ntawm kev lag luam steel thiab kev txhim kho thev naus laus zis, cov kev qhia tshwj xeeb ntawm cov xov hlau cored kuj tau txuas ntxiv txhim kho thiab txhim kho. Txoj kab uas hla thiab ntev ntawm cov xov hlau cored tau nce tas li, thiab cov kev qhia tshwj xeeb sib txawv tau tsim los rau cov txheej txheem ntau lawm. Qhov no tau txhim kho qhov ua tau zoo thiab qhov tseeb ntawm daim ntawv thov cored hlau, tso cai rau kev tswj xyuas cov txheej txheem steelmaking ntau dua.
Zuag qhia tag nrho, txoj kev loj hlob ntawm cored hlau nyob rau hauv steel kev lag luam tau zoo heev txhim kho qhov zoo thiab efficiency ntawm cov txheej txheem steelmaking.
Nrog rau kev txhim kho txuas ntxiv thiab txhim kho nws cov hom thiab cov lus qhia tshwj xeeb, cored hlau tau dhau los ua cov khoom siv tseem ceeb hauv kev lag luam steel.
Hauv kev xaus, kev txhim kho txuas ntxiv thiab txhim kho ntawm cov hom thiab cov ntsiab lus ntawm cored hlau tau ua rau muaj kev vam meej hauv kev lag luam steel. Ntau hom cored hlau yog siv rau hauv cov txheej txheem ntau lawm los txhim kho cov hlau zoo. Raws li cov khoom siv tseem ceeb hauv kev lag luam steel, cored hlau yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev txhim kho steel kev lag luam.
