Peb cov kav dej nkev roj yog tsim los siv cov thev naus laus zis-ntawm-art-art-art-art-the-art-art-the-art-art-the-art-artici thiab cov ntaub ntawv zoo los xyuas kom meej lawv lub zog, muaj zog thiab kev ua tau zoo. Cov kav dej no tau tsim tshwj xeeb los ua kom tau cov neeg muaj haujlwm siab thiab cov xwm txheej ua haujlwm hnyav. Peb to taub qhov tseem ceeb ntawm kev ntseeg siab, muaj kev nyab xeeb rau cov roj tsheb thauj khoom, yog li peb ua kom peb lub raj xa dej ua kom haum nruj qauv kev lag luam.
Ib qho ntawm cov tseem ceeb ntawm peb cov roj nkev roj yog tushelical submerged arc vuam(Hsaw) txheej txheem. Qhov kev siv vuam no cuam tshuam nrog kev siv cov kauv pob qij txha, uas txhim kho lub zog tag nrho thiab kev ncaj ncees ntawm cov yeeb nkab. Lub hsaw tus txheej txheem ua kom tiav cov fusion fusion ntawm cov hlau, uas ua rau cov yeeb nkab muaj zog uas tuaj yeem tiv taus huab siab thiab kub hloov.
Peb cov kws ua haujlwm thiab cov kws tshaj lij ua tswv yim ua raws cov txheej txheem sib tw thiab ua haujlwm kev tswj hwm zoo ntawm kev tswj hwm kom ntseeg tau tias txhua tus qauv kev kawm siab tshaj plaws. Los ntawm kev kauv vuam arcmerged arc vuam, peb tau lees tias peb cov roj hloov lub zog zoo dua thiab txhim kho cov qauv kev ntseeg.
Ntawm cangzhou Kauv Steel Kav Cov Co., Ltd., zoo yog nyob ntawm qhov tseem ceeb ntawm peb cov txheej txheem kev tsim khoom. Peb tau nqis peev tau nyob rau hauv lub xeev-ntawm-ed cov chaw thiab txiav cov tshuab thev naus laus zis los tsim cov roj roj nkev uas ntau qhov kev cia siab. Lub tuam txhab npog thaj tsam ntawm 350,000 square metres thiab muaj cov peev txheej tag nrho ntawm 680 lab yuan, uas tuaj yeem ua tau raws li kev cog qoob loo rau cov kav hlau zoo steel.
Raws li lub tuam txhab kev sib raug zoo, peb ua ntej kev nyab xeeb thiab ib puag ncig. Peb cov raj roj muaj txiaj ntsig yog tsim los txo cov xau thiab ua kom muaj kev ncaj ncees ntawm cov kev phom sij uas muaj kev phom sij thaum ib puag ncig.
Hauv cov ntsiab lus xaus, pebkhoob-Ntu kev kav dej(Tsim los ntawm cov roj nkev roj) yog qhov kev daws teeb meem zoo tshaj plaws rau kev ua tau zoo thiab nyab xeeb thaum muaj kev thauj khoom roj. Los ntawm kev siv kauv submerged arc vuam, peb cov kav dej muab lub zog zoo dua qub, durability thiab corrosion tsis kam. Ua ib qho chaw tsim khoom lag luam, canegzhou Kauv Steel kav Co., Ltd. tau cog lus los muab cov khoom lag luam zoo tshaj uas cov neeg siv khoom lag luam zoo tshaj cov neeg siv khoom. Peb thov caw koj los tshawb peb cov raj roj ntuj thiab muaj kev ntseeg siab thiab ua tau zoo. Ua haujlwm nrog peb rau txhua yam kev thauj mus los tau muaj ntuj.
