Vim li cas Ferromolybdenum Nqe Caij Nplooj Ntoos Hlav: Kev Xav Tau, Kev Pabcuam thiab Tus Nqi Tsav Tsheb

Ferromolybdenum yog dab tsi thiab Nws Yuav Ua Li Cas

Ferromolybdenum yog hlau-molybdenum master alloy ntxiv rau cov hlau thiab cam khwb cia hlau melts kom nce molybdenum cov ntsiab lus. Molybdenum txhim kho hardenability, siab - kub creep zog thiab corrosion kuj, uas yog vim li cas cov alloy yog siv nyob rau hauv quenched thiab tempered steels, cuab yeej steels thiab molybdenum- bearing stainless qib. Vim hais tias nws yog ib txwm ntxiv lig nyob rau hauv lub melting voj voog, ferromolybdenum yog yuav nyob rau hauv me me tonnages tsis tau tso nyiaj rau ib tug loj ib feem ntawm cov alloy nqi ntawm lub tiav thaum tshav kub kub.

Cov khoom lag luam yog pauv feem ntau hauv FeMo60 thiab FeMo70 tsev neeg. ASTM A132 yog cov lus qhia tshwj xeeb feem ntau hais txog ferromolybdenum muab rau cov neeg tsim khoom steel, thiab cov neeg yuav khoom ua haujlwm rau qib uas tau hais tseg, feem ntau thiab ntim ntau dua li cov lus hais.

Khoom	FeMo60, ib txwm	FeMo70, ib txwm
Molybdenum, Mo	55-65%	65-75%
Silicon, Si, max	1.5%	1.5%
Sulfur, S, max	0.10%	0.10%
Phosphorus, P, max	0.05%	0.05%
Copper, Cu, max	0.50%	0.50%
Qhov loj me	10-50 hli	10-50 hli

Cov kab saum toj no yog cov kev taw qhia qhov tseem ceeb rau kev lag luam ntau. Txhua qhov khoom xa tuaj yuav tsum tuaj txog nrog daim ntawv pov thawj ntawm kev soj ntsuam uas hais txog qhov tseeb molybdenum, silicon, sulfur thiab phosphorus cov nuj nqis, txij li kev rov qab los hauv lub ladle yog nyob ntawm qib xa tawm.

Xav tau tsav tsheb: Vim li cas Alloy Steel Consumption teeb lub suab

Ferromolybdenum xav tau yog muab tau los thov. Nws nce thiab ntog nrog lub ntim ntawm molybdenum-cov kabmob hlau thiab hlau uas yog yaj, tsis yog nrog kev lag luam dav dav li ntawd. Peb txoj kev xav tau ua tiav:

Alloy thiab engineering steel- automotive drivetrains, gears, shafts thiab fasteners noj molybdenum rau hardenability thiab qaug zog.

Roj thiab roj, lub zog thiab cov txheej txheem cog- tshav kub-tiv taus thiab corrosion- cov qib resistant nrog molybdenum ntxiv yog siv rau cov yeeb nkab, fittings thiab siab Cheebtsam.

Tool thiab tuag steels- kub ua hauj lwm thiab txias ua hauj lwm cuab yeej steels cia siab rau molybdenum rau tempering tsis kam thiab hnav lub neej.

Thaum cov mills txiav tawm, lawv feem ntau txiav siab - qib alloy ua ntej vim tias cov cua sov khi cov khoom kim ntxiv. Qhov tshwm sim yog tias kev noj ferromolybdenum tuaj yeem poob sai dua li cov hlau tsis huv, uas ua rau cov nqi poob qis uas lub khw tau ceeb toom tom qab.

Kev xa khoom, nqi nkag thiab cov khoom lag luam voj voog

Cov khoom siv raw rau ferromolybdenum tsis yog hlau ore. Nws yog molybdenum concentrate, feem ntau molybdenite, uas yog roasted rau molybdenum oxide ua ntej raug txo thiab alloyed nrog hlau. Ob qhov khoom siv tseem ceeb tshaj plaws:

Los ntawm - khoom muag- ib feem loj ntawm molybdenum concentrate yog rov qab los ntawm - khoom ntawm porphyry tooj liab mining. Thaum cov mines tooj liab nthuav dav lossis rov pib dua, molybdenum units tshwm sim ntawm kev ua lag luam txawm tias qhov kev thov molybdenum puas tsim nyog rau lawv, uas ua rau muaj qhov nyiaj seem.

Hloov peev xwm- roasting thiab metallothermic los yog hluav taws xob- cub tawg muaj peev xwm txiav txim siab sai npaum li cas tuaj yeem hloov mus rau ferromolybdenum muag. Lub peev xwm tshiab, lossis muaj peev xwm tso tawm los ntawm kev saib xyuas, loosens lub lag luam txawm tias thaum kuv cov khoom siv yog tiaj tus.

Qhov sib txawv ntawm qhov sib xyaw ua ke thiab kev xav tau steel yog li ntawd cov keeb kwm yav dhau los rau tus nqi ferromolybdenum poob.

Ntawm tus nqi, cov tswv yim tseem ceeb yog molybdenum oxide, yog li luam tawm ferromolybdenum quotations zoo li txav nrog cov kev ntsuam xyuas oxide ntxiv rau kev hloov pauv. Nyob rau hauv tas li ntawd mus rau lub hauv paus, peb theem ob tus nqi hloov pauv theem ntawm cov neeg muag khoom txaus siab rau kev lag luam:

Zog thiab reductant- roasting, smelting thiab crushing cov kauj ruam yog lub zog siv zog, yog li lub hwj chim thiab roj nqi pub ncaj qha rau hauv tus nqi hloov dua siab tshiab.

Freight thiab ntim- drummed lossis loj -cov khoom siv lub hnab txav los ntawm lub thawv lossis cov khoom tawg yog nqa cov khoom thauj uas tuaj yeem txav tau ntau feem pua ​​​​ntawm ob qho tib si hauv ib xyoos.

Cov khoom lag luam cycles- thaum cov tub lag luam xav tias tus nqi qis dua lawv destock, tso cov khoom mus rau hauv kev lag luam poob thiab ua rau kev poob qis. Thaum credit yog kim, tsawg tus neeg yuav khoom nqa cov khoom lag luam, uas tshem tawm qhov kev txhawb nqa.

Txoj Cai Kev Lag Luam, tariffs thiab txiaj raws

Txoj cai thiab cov txiaj ntsig hloov pauv tus nqi uas tus neeg yuav khoom them tiag tiag txawm tias tus nqi ntawm cov hlau tsis hloov pauv.

Export lub luag haujlwm thiab quotasnyob rau hauv cov teb chaws tsim tsa tus nqi ntawm cov units tawm hauv lub hauv paus chiv keeb thiab redirect luam flows.

Ntshuam tariffs thiab tiv thaiv - kev ntsuas pov tseghloov tus nqi tsaws ntawm qhov chaw thiab feem ntau thawb cov khoom mus rau qhov twg lub khw tseem qhib.

Cov nqi pauvtxiav txim siab tus nqi hauv zos - txiaj. Ib tug neeg yuav khoom nyob rau hauv ib lub txiaj uas muaj zog tiv thaiv cov txiaj ntsig ntawm cov lus hais pom tus nqi qis dua yam tsis muaj kev hloov pauv hauv kev lag luam hlau.

Kev sib txhuam kev lag luam kuj cuam tshuam rau qhov xav tau: kev tsis paub meej ntawm cov nqi se ncua kev nqis peev hauv cov hlau- siv cov haujlwm uas yuav txwv tsis pub nqus cov hlau.

Tswj kev yuav khoom hauv kev lag luam poob qis Ferromolybdenum

Tus nqi poob muab nqi zog rau kev qhuab qhia ntau dua li kev khaws cia. Cov tswv yim ntsuas rau lub khw muag khoom lossis lub rooj lag luam muaj xws li:

Txuas cov nqi cog lus rau kev tshaj tawm oxide lossis ferromolybdenum kev ntsuam xyuas nrog rau lub sijhawm siv.

Shorten quotation validity thiaj li hais tias ib tug poob lag luam yog reflected nyob rau hauv lub tom ntej no kev txiav txim es tsis txhob muab xauv rau hauv.

Yuav kom noj thiab rov ua dua - xaj ntawm qhov chaw ruaj khov, siv qhov kev poob qis los sim cov khoom lag luam teb lub sijhawm es tsis tsim cov khoom muag.

Qhia qhov loj me me uas phim qhov kev coj ua: cov pob loj loj tuaj yeem zaum tsis tau, thaum cov nplua nplua ntau ua rau oxidation poob.

Kev soj ntsuam daim ntawv pov thawj ntawm kev tshuaj xyuas tiv thaiv qib uas tau tshaj tawm, vim hais tias hauv cov khw muag khoom muag khoom marginal feem ntau yuav tshwm sim.

Cov lus nug Cov neeg yuav khoom nug txog Ferromolybdenum Nqe

Q: Dab tsi yog tus tsav tsheb loj tshaj plaws ntawm ferromolybdenum nqi?
Tus nqi ntawm molybdenum oxide units, ua ke nrog lub ntim ntawm molybdenum -cov kabmob steel tau yaj. Txoj cai, kev thauj khoom thiab cov txiaj ntsig cuam tshuam txav tus nqi uas tus neeg yuav khoom them, tab sis lawv ua haujlwm saum toj ntawm ob lub hauv paus.

Q: Puas yog tus nqi ntawm cov hlau ore cuam tshuam rau ferromolybdenum nqi?
Tsis yog, thiab qhov no yog ib qho kev xav tsis zoo. Hlau ore tsis yog qhov chaw molybdenum hauv ferromolybdenum. Cov khoom noj uas cuam tshuam yog molybdenum concentrate, uas yog ci rau oxide thiab tom qab ntawd alloyed nrog hlau thaum smelting.

Q: Cov qib ferromolybdenum twg tau pauv ntau zaus?
Cov tsev neeg FeMo60 thiab FeMo70 ua lag luam ua lag luam, nrog cov ntsiab lus molybdenum kwv yees li 55-65% thiab 65-75%. Cov hlau uas xav tau ib qho me me molybdenum ntxiv feem ntau yog alloyed nrog qib qis.

Q: Vim li cas cov nqi ferromolybdenum poob sai dua cov nqi hlau?
Vim tias molybdenum- cov qib bearing yog ib feem me me ntawm phau ntawv txiav txim zeb, lawv raug txiav ua ntej thaum qhov kev thov tsis muaj zog. Alloy xav tau yog li ntawd cog lus ntau sharply tshaj cov khoom siv raw khoom, thiab cov concentrate sab ntawm kev ua lag luam tsis kho sai li sai tau.

Q: Qhov luaj li cas feem yuav tsum tau txiav txim?
Feem ntau steelmakers qhia 10-50 mm rau ladle lossis rauv ntxiv. Finer fractions yaj sai dua tab sis oxidise yooj yim dua, yog li qhov kev xaiv raug yog nyob ntawm kev them nqi, slag tej yam kev mob thiab tus nqi rov qab lub khw muag khoom yog npaj los txais.

Q: Yuav ua li cas daim ntawv cog lus yuav tsum tau teeb tsa thaum tus nqi poob?
Siv lub sijhawm luv luv ua ke nrog qhov ntsuas ntsuas, thiab cais cov npoo hloov pauv los ntawm cov khoom siv raw. Txoj kev ntawd qhov kev poob qis hauv cov txiaj ntsig oxide dhau mus rau tus neeg yuav khoom thaum tus nqi hloov pauv nyob twj ywm pob tshab.
