Thaum ntsuascored hlau nqi rau steelmaking, buyers yuav tsum tsis txhob sib piv hais ib leeg. Qhov sib piv muaj txiaj ntsig yog nruab nrabquoted tus nqi thiab qhov kev kho mob tiag tiag, vim hais tias hlau zoo ncaj qha cuam tshuam rau calcium rov qab, noj stability, hlau tawg, thiab zaum kawg inclusion tswj nyob rau hauv lub ladle furnace. Raws li lub Plaub Hlis 1 Tuam Tshoj xa tawm siv,CaSi cored hlau (Ca30Si60, 13mm)yog quoted ntawmFOB Tianjin 1300-1330 Tuj, Ca28Si55 cored hlau (13 hli)ntawmFOB Tianjin 1160-1180 Tuj, thiabcov khoom ntshiab calcium hlau (Ca Ntau dua lossis sib npaug 98%, 9 mm, Ca 58–68 g / m)ntawmFOB Tianjin 1450-1540 ton. Hauv kev xyaum, qhov qis qis qis qis tsis yog ib txwm ua tus nqi qis dua steelmaking, vim tias tsis ruaj khov, tsis muaj zog strip zoo, thiab hlau tawg tuaj yeem txo qhov rov qab thiab nce nqi kho tag nrho.
Vim li cas Cored Wire Nqe Tsis zoo li tus nqi kho mob?
Hauv ladle furnace ua haujlwm, tus nqi them nqi tsuas yog tus nqi pom. Tus nqi zais tshwm thaum pub mis. Yog hais tias cov hlau tsis pub smoothly, yog hais tias lub seam qhib thaum ntxov, yog hais tias tus filling ratio yog tsis ruaj tsis khov, los yog yog hais tias calcium tsis nkag mus rau hauv lub molten hlau, cov nroj tsuag yuav noj ntau hlau mus cuag tib lub hom phiaj metallurgical.
Qhov no yog vim li cas tej buyers tsis tshua txiav txim cored hlau los ntawm tuj nqi ib leeg. Lawv saib seb cov xaim xaim xaim li cas hauv qhov cub: kev noj zaub mov ruaj khov, kev rov ua kom zoo dua qub, thiab cov txiaj ntsig kho tau rov qab.
Ib lub xaim pheej yig dua tuaj yeem kim dua thaum:
- hlau tawg cuam tshuam kev noj mov
- calcium rov qab yog tsawg
- hmoov filling tsis sib npaug
- strip thickness tsis ruaj khov
cov hlau ntxiv yuav tsum tau noj los kho cov cua sov
Vim li cas thiaj yuav tsum Metallurgical Cored Hlau Tsis txhob muab piv nrog Ordinary Vuam Hlau?
Ib qho ntawm feem ntau kev lag luam tsis to taub yog khometallurgical cored hlauzoo li nws zoo ib yam li cov vuam hlau zoo tib yam. Qhov kev sib piv ntawd yog technically tsis zoo.
Lub vuam hlau yog tsim los rau arc stability thiab weld deposition. Lub hlau cored hlau yog tsim los rau siab - ceev ceev pub rau hauv cov hlau molten, qhov uas nws yuav tsum tswj cov duab nyob rau hauv lub siab noj, ciaj sia tuav thiab cia, thiab tso tawm nws active core nyob rau hauv lub qhov tob ntawm lub ladle. Lub strip thickness, seam ncaj ncees, thiab sau logic yog txawv kiag li.
Thaum cov neeg yuav khoom tsis quav ntsej qhov kev sib txawv no, lawv feem ntau kwv yees vim li cas qee qhov qis -cov nqi xaim tsis siv. Ib lub xaim uas zoo nkaus li siv tau ntawm lub reel yuav flatten, tawg, los yog tawg thaum lub sij hawm pub mis yog hais tias lub strip nyias nyias los yog cov khoom tsis sib xws. Thaum qhov no tshwm sim, cov txiaj ntsig kev kho mob yuav tsis ruaj khov thiab qhov pom tseeb tus nqi zoo dua ploj mus.
Tam sim no Export Market Reference yog dab tsi rau Steelmaking Cored Hlau?
