** 1. Plaub yam tshuaj carbon hlau yog dab tsi? **
Plaub hom ntawm cov roj carbon steel tau faib raws lawv cov ntsiab lus carbon:
* ** STUPON STEEL (hlau me): ** muaj txog 0.3% carbon. Nws yog mos, ductile, yooj yim rau daim ntawv, thiab hom feem ntau.
* ** MENTERLOLOGY STEEL: ** muaj ntawm 0.3% thiab 0.6% carbon. Nws muaj kev sib npaug zoo ntawm lub zog thiab ductility thiab tuaj yeem ua cua sov {{}} kho.
* ** High carbon hlau: ** muaj ntawm 0.6% thiab 1.0% carbon. Nws yog qhov muaj zog heev, nyuaj, thiab hnav - tiv taus tab sis tsis tshua muaj condile.
* ** QIB HANAGE STEEL: ** muaj ntawm 1.0% thiab 2.0% carbon. Nws yog qhov nyuaj heev thiab nkig, siv rau cov ntawv thov tshwj xeeb xws li cov cuab yeej txiav thiab springs.
** 2. Dab tsi yog tag nrho daim ntawv ntawm HFS thiab ERW? **
* ** HFS ** sawv rau ** kub tiav seamless ** (raj lossis yeeb nkab).
* ** ERW ** sawv rau ** hluav taws xob tiv thaiv welded ** (raj lossis yeeb nkab).
** 3. Dab tsi yog qhov txawv ntawm ERW thiab LSAW? **
Thawj qhov sib txawv ntawm lawv cov txheej txheem tsim khoom thiab qhov tshwm sim loj thiab lub zog ntawm cov yeeb nkab.
* ** ERW (hluav taws xob tiv thaiv welded) ** Yeeb xyaw welded) ** Yeeb xyaw} ua rau cov hlau dov rau hauv cov leeg siv hluav taws xob. Nws yog feem ntau yog siv rau cov kav dej uas muaj me me (txog li 24 ntiv taw) thiab txo qis cov ntawv thov.
* ** LSAWW (Longitudinal submerged arc vuam vuam) ** Yeeb nkab yog ua los ntawm dabtsi yog khoov thiab sib sau cov phiaj hlau. Tom qab ntawv ntev yog mam li welded ntawm ob sab hauv thiab sab nraud siv cov submerged Arc vuam txheej txheem. LSAWaw kav loj yog loj {2} txoj kab uas hla nrog cov phab ntsa hickes, tsim los kom muaj roj thiab roj hloov hluav taws xob.
** 4. Dab tsi yog HFS hauv hlau? **
** HFS (kub thawj seamless) ** Yog hais txog ib hom ntawm seamless steel yeeb nkab lossis raj. Nws yog tsim los ntawm cov cua kub cov khoom siv hlau billet thiab tho nws los ua lub ntsej muag khoob. Lub plhaub no yog kub - rolled thiab ncab kom ua tiav qhov loj me thiab phab ntsa tuab. Lub "Khawm Kub Ua tiav" Cov txheej txheem ua rau cov yeeb nkab nrog lub zog sib tw tab sis muaj zog dua thiab muaj peev xwm metallurgical piv rau cov khoom txias.
** 5. Uas yog qhov zoo dua, seamless lossis ERW YEEB? **
Tsis muaj ib qho "zoo dua" kev xaiv; Cov kev xaiv yog nyob ntawm daim ntawv thov cov cai.
* ** SEAMLESS YEEB ** yog qhov zoo dua rau qhov siab- pa, siab} pa dej, siab- siab} tshuab siab hydraulic). Nws tsis muaj nqaws weld, ua kom muaj zog thiab txhim khu kev qha nyob rau hauv kev ntxhov siab heev thiab kev mob corrosive. Txawm li cas los xij, nws kim dua.
* ** ERW cov yeeb nkab ** yog kev lag luam ntau dua thiab haum rau cov ntawv thov qis dua (piv txwv li cov kav dej, fencing, qauv txheej txheem). Niaj hnub new cov txheej txheem tau txhim kho weld zoo, tab sis cov leeg tseem muaj lub peev xwm ntawm qhov tsis ua tiav. Nws yog xaiv rau nws tus nqi - ua hauj lwm zoo thiab muaj nyob ntev txuas ntxiv ntev.
