High Carbon Ferrochrome Spot Reference Nqe rau lub Plaub Hlis 30

High Carbon Ferrochrome Spot Reference Nqe thiab Yuav Nyeem Li Cas

Cov pa roj carbon ntau ferrochrome yog qhov loj tshaj plaws ntawm ib qho hlau alloy nkag mus rau hauv cov hlau tsis muaj steel, thiab cov kev ntsuam xyuas pom tau tshaj tawm hauv cheeb tsam los ntawm cheeb tsam vim tias chromium thiab silicon cov ntsiab lus sib txawv thiab vim hais tias chav tsev hais tsis yog tus nqi ib tonne. Lub Plaub Hlis 30 qhov chaw siv hauv qab no tau hais hauv RMB ib 50 lub hauv paus tuj, nyiaj ntsuab suav nrog se, nrog rau cov nqe lus them nqi thiab xa khoom raws li tau hais los ntawm tus tshaj tawm.

50 Base Ton Convention tau piav qhia

Ib qho kev tsocai hais txog ib 50 lub hauv paus tuj txhais tau hais tias tus nqi yog teev rau ib metric ton ntawm alloy normalized mus rau 50% chromium hauv paus, tsis yog rau qhov tseeb tonnage raws li nws tawm ntawm lub tsheb. Rau nqi ib pob khoom tiag tiag, lub hauv paus nqe lus yog ntsuas los ntawm qhov tseeb chromium tsom xam muab faib los ntawm 50. Noj cov kab Indian ntawm 8400 RMB ib 50 lub hauv paus ton thiab xa tawm ntawm 60% Cr, cov chromium - tus nqi qub yog 8400 x (60 / 50) {{110 ton, 2000 tonnes, 20000000 nbsp; ua ntej qhov loj me ntawm cov pa roj carbon monoxide. Cov rooj sib tham no tshwm sim kom cov khoom sib txawv nrog cov qib chromium sib txawv tuaj yeem muab piv rau ntawm ib kab, thiab nws yog vim li cas ob lub ntsiab lus uas sib nrug deb tuaj yeem nyob ze thaum kev tshuaj xyuas. Cov neeg yuav khoom yuav tsum paub tseeb tias qhov kev ntsuam xyuas tau tshaj tawm yog los ntawm tus neeg muag khoom daim ntawv pov thawj lossis los ntawm tus neeg yuav khoom- sab kev soj ntsuam, vim tias ib qho - taw tes chromium sib txawv txav tus nqi txiav txim siab li 2%.

Vim li cas Silicon thiab Cr rau Fe Ratio Matter

Cov kab Indian thiab Southern African nqa 3 - 4% silicon, thaum Kazakh kab yog kwv yees li 0.5%. Silicon yog ib qho kev txiav txim siab ntawm tus nqi chrome xyaum hauv qee cov smelters vim nws txhim kho fluidity thiab rov zoo, tab sis nyob rau hauv lub khw steel nws yog ib qho ntxiv deoxidation load thiab nws tso cua sov thaum nws oxidises. Tus kws tsim cov hlau tsis muaj steel nrog kev tswj qhov kub thiab txias hauv lub converter tuaj yeem lees txais cov khoom siv silicone siab dua ntawm tus nqi qis dua, thaum lub khw them nyiaj rau hauv chav da dej kub twb tau them rau qib qis - silicon. Qhov sib piv ntawm chromium rau hlau yog qhov sib txawv thib ob: qhov sib piv ntau dua txhais tau tias ntau chromium units ib tonne ntawm alloy thiab tsawg dua dilution ntawm stainless tsom xam, uas tseem ceeb thaum lub tshav kub yog balanced tiv thaiv ib tug ruaj nickel ntxiv. Tsis muaj qhov sib txawv tsis tau raug ntes nyob rau hauv lub hauv paus nqe lus, yog li ob leeg yuav tsum tau them nqi rau hauv cov nqe lus hais daws.

Standards thiab Qib Frameworks

Ferrochromium tau teev tseg los ntawm chromium thiab carbon cov ntsiab lus, thiab qib naming convention ua raws li cov logic. ASTM A101, tus qauv specification rau ferrochromium, npog cov tshuaj muaj pes tsawg leeg uas yuav tsum tau nyob rau hauv lub ferrochrome tsev neeg, nrog rau cov ferrochrome - qib silicon. GB/T 5683, Suav ferrochromium tus qauv, xaiv cov qib los ntawm cov ntsiab lus chromium thiab qib carbon, yog li qib siab -carbon yog lub npe rau cov ntsiab lus chromium ua ke nrog lub qab nthab. Nyob rau hauv ib qho kev txiav txim nws yog ib txwm txaus los kho tus qauv, qhov kev xaiv, chromium thiab carbon ranges, silicon qab nthab, thiab band loj, thiab ces yuav tsum tau daim ntawv pov thawj ntawm kev tsom xam rau qhov tshwj xeeb. High- qib carbon raug xaiv rau cov chromium ntau ntxiv qhov twg cov pa roj carbon khaws- tsis txwv; qhov twg qhov kawg carbon specification yog nruj, qis dua - qib carbon ferrochrome lossis kev ua kom zoo dua yuav tsum tau siv.

Logistics, Packing thiab Inspection

Export parcels ntawm high carbon ferrochrome feem ntau ntim rau hauv 1 MT lub hnab loj rau lub thawv xa khoom, los yog muab rau hauv cov khoom loj rau cov khoom thauj loj, nrog cov crushed loj band tshuaj ntsuam xyuas kom tshem tawm cov nplua uas yuav tsis poob zoo li plua plav. Ib qho steelmaking band yog 10-50 mm, txawm hais tias ib coarser band siv qhov chaw them nyiaj tuaj yeem ua tau. Kev tshuaj xyuas yog los ntawm lub koom haum thib peb lossis los ntawm kev tsim cov haujlwm, thiab daim ntawv pov thawj yuav tsum tau tshaj tawm chromium, carbon, silicon, sulfur thiab phosphorus ua ke nrog qhov loj me. Qhov twg qhov kev sib hais haum raws li tus nqi 50 lub hauv paus, qhov kev tsom xam uas tsav cov kev suav yuav tsum tau pom zoo ua ntej xa khoom thiab yuav tsum tau kos los ntawm cov qauv uas ob tog txais, txwv tsis pub qhov sib txawv me me txhais ncaj qha rau hauv kev sib cav txog kev them nyiaj.

Cov lus nug nquag

Q:Dab tsi yog "ib 50 lub hauv paus tuj" txhais li cas hauv cov lus hais ferrochrome?
A: Nws txhais tau hais tias tus nqi siv rau ib qho metric tuj ntawm cov hlau tsis zoo rau 50% chromium hauv paus. Tus nqi sib hais yog qhov kev tsocai muab faib los ntawm qhov tseeb chromium cov ntsiab lus faib los ntawm 50.

Q:Vim li cas Kazakh kab siab dua cov kab Indian thiab Southern African?
A: Cov khoom siv Kazakh nqa ntau dua chromium tsom xam thiab qis dua silicon, yog li nws xa ntau chromium units ib tonne thiab tsawg deoxidation load, uas txhawb nqa lub hauv paus siab dua.

Q:Cov qauv twg npog ferrochromium?
A: ASTM A101 qhia txog ferrochromium muaj pes tsawg leeg hauv tsev neeg, suav nrog ferrochrome- qib silicon, thiab GB / T 5683 xaiv Suav ferrochromium qib los ntawm chromium cov ntsiab lus thiab qib carbon.

Q:Thaum twg yuav tsum tau siv qis-carbon ferrochrome es tsis txhob siab - cov khoom siv carbon?
A: Thaum kawg cov ntsiab lus steel txwv cov pa roj carbon khaws- nce. Cov qib siab - carbon qib yog rau cov chromium ntau ntxiv qhov twg cov pa roj carbon monoxide tuaj yeem nqus los ntawm cov nqi sib npaug.

Q:Yuav ua li cas yog high carbon ferrochrome ntim rau export?
A: Feem ntau hauv 1 MT lub hnab loj rau cov thawv ntim khoom lossis hauv cov khoom loj rau cov khoom loj, nrog rau qhov ntsuas qhov loj xws li 10-50 hli kom txo cov nyiaj poob qis.

Q:Puas yog cov duab no muaj kev ruaj ntseg?
A: Tsis yog. Lawv yog ib qho - kev sib tham qhov chaw siv sau rau hnub ntawd, nyiaj ntsuab suav nrog se, thiab siv rau kev ntsuas es tsis yog cov ntawv cog lus.
