Khoom Description
Calcium silicate cored hlau yog ib qho tseem ceeb hauv kev tsim steel niaj hnub no. Nws yog ib hom cored hlau uas muaj calcium silicate hauv cov tub ntxhais, thiab feem ntau muaj txoj kab uas hla ntawm 13 hli. Cov hlau cored yog ntxig rau hauv cov hlau yaj, uas tom qab ntawd tso cov calcium rau cov hlau molten, ua rau cov ntsiab lus calcium ntau dua.
Cov ntsiab lus calcium siab hauv steel muaj ntau yam txiaj ntsig. Nws txhim kho cov khoom siv hluav taws xob ntawm cov hlau, txo cov kev tsis sib xws, thiab txhim kho cov hlau zoo ntawm cov hlau. Tsis tas li ntawd, nws tuaj yeem txo qhov nozzle clogging, txo qis qhov tsis xws luag, thiab ua rau kom muaj txiaj ntsig ntawm desulfurization.
Ib xyoos ib zaug muab cov calcium silicate cored hlau ua kom muaj kev ruaj khov thiab ruaj khov ntawm cov txheej txheem steel ntau lawm. Nws tuaj yeem pab kom tsis txhob ncua sijhawm, txo cov nqi tsim khoom, thiab txhim kho cov khoom zoo kawg nkaus. Yog tsis muaj kev ntseeg siab ntawm calcium silicate cored hlau, steelmakers yuav raug yuam kom nrhiav lwm txoj hauv kev kom ua tiav cov ntsiab lus calcium uas xav tau hauv cov hlau. Cov txheej txheem no yuav siv sijhawm ntev, raug nqi, thiab tuaj yeem cuam tshuam qhov kawg ntawm cov hlau.
Yuav kom tswj tau cov khoom siv tas mus li ntawm calcium silicate cored hlau, cov tuam txhab steel yuav tsum tau ua kom muaj cov khoom siv ruaj khov, cov txheej txheem tsim khoom txhim khu kev qha, thiab cov khoom muag txaus ntawm cov khoom tiav. Tsis tas li ntawd, kev xa khoom zoo thiab kev xa tawm tuaj yeem ua kom lub sijhawm xa khoom ntawm calcium silicate cored hlau rau cov neeg siv khoom.
Ntxiv mus, cov tuam txhab lag luam yuav tsum ua raws li cov qauv kev tswj hwm nruj kom ntseeg tau tias calcium silicate cored hlau ua tau raws li qhov tsim nyog specifications. Los ntawm kev ua li ntawd, lawv tuaj yeem lav tias cov hlau cored yuav ua haujlwm raws li qhov xav tau thiab pab ua tiav cov ntsiab lus calcium uas xav tau hauv cov hlau.
Kev nqis peev hauv kev tshawb fawb thiab kev tsim kho kuj tuaj yeem pab txhim kho cov txheej txheem tsim khoom, txo cov nqi, thiab txhim kho qhov zoo ntawm calcium silicate cored hlau. Cov thev naus laus zis tshiab thiab cov txheej txheem tuaj yeem tsim los ua kom muaj txiaj ntsig ntawm cov txheej txheem tsim khoom, txo cov khoom pov tseg, thiab ua kom cov khoom sib xws.
Tsis tas li ntawd, kev sib koom tes ntawm cov tuam txhab steel thiab calcium silicate cored hlau manufacturers tuaj yeem ua rau muaj txiaj ntsig zoo. Cov tuam txhab hlau tuaj yeem muab cov lus qhia muaj txiaj ntsig rau cov tuam txhab ntawm qhov zoo thiab kev ua haujlwm ntawm cov hlau cored, uas tuaj yeem pab txhim kho kev rov ua haujlwm yav tom ntej. Tsis tas li ntawd, cov neeg tsim khoom tuaj yeem siv cov lus tawm tswv yim no los kho cov txheej txheem tsim khoom thiab tsim cov khoom tshiab los ntawm cov kev xav tau tshwj xeeb ntawm lawv cov neeg siv khoom.
Nyob rau hauv xaus, ib tug perennial mov ntawm calcium silicate cored hlau yog qhov tseem ceeb rau steelmaking kev lag luam. Nws tsis tsuas yog txhim kho qhov zoo ntawm cov hlau, tab sis kuj ua kom muaj kev ruaj khov thiab ruaj khov ntawm cov txheej txheem steel ntau lawm. Cov tuam txhab hlau yuav tsum tau nqis peev rau hauv cov khoom siv raw, cov txheej txheem ntau lawm, kev tswj kom zoo, thiab kev tshawb fawb thiab kev txhim kho kom ntseeg tau tias muaj cov calcium silicate cored hlau ruaj khov. Kev sib koom tes ntawm cov tuam txhab steel thiab cov tuam txhab lag luam tuaj yeem ua rau muaj kev sib koom ua ke thiab txhawb kev loj hlob hauv kev lag luam. Nrog rau cov kev siv zog no, kev lag luam steelmaking tuaj yeem txuas ntxiv vam meej thiab muab cov hlau zoo rau ntau yam kev siv.
