Qhov kev ntsuam xyuas lub Tsib Hlis 23 qhia li cas
Molybdenum slab yog ib nrab -tiav billet los ntawm molybdenum phaj, daim ntawv thiab pas nrig yog tsim, thiab nws cov nqi txav nrog cov oxide thiab ferromolybdenum kev lag luam nyob rau hauv nqes hav thiab nrog zeb conversion peev downstream. Lub Tsib Hlis 23 kev soj ntsuam rau cov cheeb tsam Suav loj tau sau cov molybdenum slabs ntawm 6 kg thiab siab dua ntawm 44.00-44.50 hauv units ntawm kaum txhiab yuan ib tonne, nce 0.5 ntawm qhov kev ntsuam xyuas yav dhau los, thiab loj molybdenum pas nrig ntawm 50-70 mm txoj kab uas hla thiab 247 kg.0 thiab siab dua ntawm tib lub 247 kg.0 thiab saum toj no. 0.5.
Qhia nyob rau hauv daim ntawv paub ntau dua, cov slab band yog kwv yees li 440,000-445,000 CNY ib tonne thiab cov pas nrig loj txog 470,000-475,000 CNY ib tonne. Qhov 3,000 CNY ib tonne qhov sib txawv ntawm ob kab yog qhov pom tus nqi ntawm qhov ntxiv deformation, annealing thiab tiav ua hauj lwm uas hloov ib tug sintered los yog forged billet rau hauv ib tug tiav loj-inch pas nrig.
Nqe Table rau Slab thiab Qws
| Khoom | Specification | Nqe (ib txhiab CNY / t) | Hloov | Chav tsev |
|---|---|---|---|---|
| Molybdenum slab | 6 kg thiab siab dua | 44.00-44.50 | nce 0,5 | 10,000 CNY ib tonne |
| Loj molybdenum pas nrig | 50-70 mm inch, 25 kg thiab siab dua | 47.00-47.50 | nce 0,5 | 10,000 CNY ib tonne |
Rau tus neeg yuav khoom sib piv cov txiaj ntsig sib txawv, tus lej lej yog ncaj qha: 440,000-445,000 CNY ib tonne yog 440-445 CNY ib kilogram, thiab ntawm qhov kwv yees li ntawm 7.1 CNY ib US duas uas yog kwv yees li 62-63 USD ib kilogram ntawm molybden. Tus nqi siv yuav tsum tau teev nyob rau hauv kev sib piv, vim hais tias ib tug 2% txiaj pauv hloov qhov qeb duas ntawm ob tug neeg muag khoom hais nyob rau hauv txawv cov nyiaj.
Slab, Billet thiab Finished Qws: Qhov twg tus nqi zaum
Tus nqi ntawm molybdenum slab tsuas yog ib feem ntawm tus nqi ntawm molybdenum. Peb cov nqi thaiv zaum saum cov hlau. Ua ntej, kev npaj hmoov: molybdenum oxide thiab ammonium molybdate raug txo kom cov hmoov hlau, thiab qib hmoov txiav txim siab qhov ua tiav purity. Thib ob, kev sib sau ua ke: cov hmoov yog nias thiab sintered, thiab cov slabs hnyav dua yuav raug ntxiv los ntawm kub isostatic nias lossis los ntawm lub tshuab nqus tsev arc melting, ob qho tib si ntxiv tus nqi tab sis kuj txhim kho qhov ntom ntom thiab txo qhov porosity. Thib peb, deformation thiab xov: forging, dov, annealing, straightening, machining thiab deg txias. Ib tug pas nrig tiav yog nqa tag nrho peb lub blocks, uas yog vim li cas nws ua lag luam saum lub slab.
Qhov hnyav tseem ceeb heev. Qhov tshwj xeeb ntawm 6 kg thiab siab dua rau slab thiab 25 kg thiab saum toj no rau cov pas nrig loj tsis yog arbitrary; Cov khoom hnyav dua xav tau cov xovxwm loj dua thiab ntev sintering cycles, thiab lawv hais kom sib txawv cov ntsiab lus ntau dua li cov ntawv me me.
Standard Requirements thiab Purity
Cov khoom lag luam molybdenum raug txiav txim rau lub teb chaws thiab thoob ntiaj teb specifications, suav nrog GB / T 3462 rau molybdenum tuav thiab slabs nyob rau hauv Suav lag luam, ASTM B386 rau molybdenum thiab molybdenum alloy phaj, ntawv, sawb thiab ntawv ci, thiab ASTM B387 rau molybdenum bar, qws thiab hlau. Tus qauv coj mus muag purity yog 99.95% molybdenum, nrog qhov sib npaug ua los ntawm cov khoom seem thiab cov khoom siv hlau. Interstitials tseem ceeb tshaj plaws: oxygen, nitrogen, carbon thiab hydrogen tswj ceev, ductility thiab tus cwj pwm ntawm cov khoom thaum dov, thiab lawv yuav tsum tau tshaj tawm rau daim ntawv pov thawj ntawm kev soj ntsuam.
Cov khoom siv tsis tu ncua siv rau kev tsim thiab ntsuas qhov hnyav yog qhov ntom ntawm 10.2 g / cm3 thiab qhov taw tes melting ntawm 2,623 degC. Because density is close to that value only when the consolidation route has produced a fully dense body, the measured density should be checked rather than assumed, especially for slabs produced by pressing and sintering alone.
Daim Ntawv Thov Uas Xav Tau
Molybdenum yog siv rau qhov chaw melting siab, siab - qhov kub thiab txias, tsis tshua muaj thermal expansion thiab zoo thermal conductivity yuav tsum tau ua ke. Cov ntawv thov raug siv yog electrodes thiab iav- melting Cheebtsam, cua sov cov ntsiab lus thiab shields nyob rau hauv lub tshuab nqus tsev vacuum furnaces, pwm thiab tuag rau siab- kub tsim, sputtering lub hom phiaj, cov khoom nyob rau hauv lub electronics thiab semiconductor industries, thiab alloy ntxiv nyob rau hauv stainless thiab cov cuab yeej steels. Slab thiab pas nrig hnyav yog cov ntawv pub rau cov khoom no, yog li thov rau slab lem ob lub steel hlau ua lag luam thiab cov refractory hlau fabrication sector.
Cov lus nug nquag
Q:Dab tsi yog molybdenum slab?
A: Nws yog ib nrab - ua tiav molybdenum billet, feem ntau ntawm 6 kg thiab siab dua, ua los ntawm nias thiab sintering molybdenum hmoov thiab, qhov twg yuav tsum tau, ntxiv densified. Nws yog dov los yog forged rau hauv phaj, ntawv los yog pas nrig.
Q:Vim li cas cov pas nrig molybdenum loj dua li slab?
A: Nyob rau lub Tsib Hlis 23 kev soj ntsuam cov pas nrig yog kwv yees li 3,000 CNY ib tonne siab dua. Qhov sib txawv suav nrog forging, dov, annealing, straightening thiab tiav kev ua haujlwm uas lub slab tsis tau txais.
Q:Dab tsi purity yog tus qauv rau kev lag luam molybdenum?
A: 99.95% molybdenum yog tus qauv coj mus muag purity, nrog interstitial thiab metallic residuals tswj thiab tshaj tawm ntawm daim ntawv pov thawj ntawm kev soj ntsuam.
Q:Kuv yuav hloov tus nqi li cas rau ib -kilogram daim duab?
A: Faib los ntawm kaum. Ib qho kev tsocai ntawm 44.00-44.50 hauv units ntawm kaum txhiab yuan ib tonne sib npaug 440,000-445,000 CNY ib tonne, uas yog 440-445 CNY ib kilogram.
Q:Cov qauv twg npog molybdenum slab thiab pas nrig?
A: GB / T 3462 npog molybdenum tuav thiab slabs hauv Suav lag luam, ASTM B386 npog phaj, ntawv, sawb thiab ntawv ci, thiab ASTM B387 npog bar, pas nrig thiab hlau.
Q:Dab tsi txiav txim siab qhov loj ntawm slab xaj?
A: Cov khoom tiav. Heaver slab thiab pas nrig xav tau cov xovxwm loj dua thiab ntev sintering cycles, yog li cov lus hais hloov pauv; cov neeg yuav khoom feem ntau txhim kho qhov hnyav ntawm qhov ntev ntawm lub phaj kawg lossis pas nrig.
