Kev hais lus txog tungsten, koj tuaj yeem xav txog zaj dab neeg ntawm Edison' s kev tsim kho ntawm lub teeb ua kom pom tseeb. Edison nyob rau hauv thiaj li yuav nrhiav tau txoj cai filament khoom, nws yuav piav qhia raws li painstakingand sau ntau tshaj 3000 yam ntawm cov ntaub ntawv conductive ib los ntawm ib xeem, thaum kawg xaiv tungsten xaim. Vim hais tias tungsten tsis tsuas yog ua hluav taws xob zoo, tab sis kuj tsis' t hlawv tawm ntawm qhov kub siab tshaj 3,000 ° C, nws cov ntsiab lus melting (3,410 ° C) yog qhov ntau tshaj plaws ntawm ib qho hlau, ua rau nws zoo tagnrho rau cov filaments.
Ntxiv rau, tungsten muaj lwm tus yam ntxwv, uas yog qhov nyuaj! Nyob rau hauv cov xwm, tungsten yog thib ob tsuas yog pob zeb diamond hauv hardness. Tias' s vim li cas nws' s hu ua" kev lag luam hniav" thiab yuav ntxo yuav luag txhua yam. Yog hais tias tsuas yog siv tungsten los ua tus lim, nws yog overqualified. Dab tsi ntxiv yog tungsten siv rau? Koj tuaj yeem tau ib nyuag ntsia ntawm nws los ntawm lwm cov npe -" King of War Hlau" ;.
Daim duab
Lub hardness ntawm alloy hlau nrog ntxiv ntawm tungsten yuav zoo heev hloov kho. Thaum ntxov ntawm lub xyoo pua puv 19, German cov kws tshawb fawb tau tshawb pom tias ntxiv cov tungsten rau cov phom phom ua rau muaj rab phom phom ntau dua; Thaum Lub Ntiaj Teb Tsov Rog Thoob Ntiaj Teb thib II, tungsten tau siv nyob rau hauv lub hleb phom tej rab phom, zoo li lub taub hau German Tiger tank, uas siv tungsten carbide cores. Txog niaj hnub no, tungsten tau siv los ua superalloys rau cov cav hlau, foob pob ua ntxaij, hluav taws xob cannons thiab txawm tias lub nkoj thauj khoom, qhov chaw uas cov hlau txuas. Pom, qhov tseem ceeb ntawm tungsten hauv kev tiv thaiv kev tiv thaiv hauv tebchaws.
Qhov tseeb, tsis tsuas yog nyob hauv kev tiv thaiv kev lag luam, tam sim no tungsten tau siv dav hauv metallurgy, cov ntaub ntawv siv hluav taws xob, tshuaj lom neeg, kev siv tshuab, aerospace thiab lwm cov teb, zoo li lub ntiaj teb tsis tshua muaj, tau dhau los ua cov hlau tseem ceeb hauv kev tsim ntau cov khoom siv qib siab. khoom. Thiab tus nqi no yog sib npaug nrog cov peev txheej tseem ceeb ntawm cov khoom ntiaj teb tsis tshua muaj, kuj yog ib hom kev lag luam muaj txiaj ntsig hauv peb lub teb chaws.
Raws li cov ntaub ntawv tso tawm los ntawm Tebchaws Meskas Kev Tshawb Fawb Kev Tshawb Fawb (USGS), txog xyoo 2018, cov khoom pov thawj thoob ntiaj teb ntawm cov khoom siv tungsten yog 3.3 lab tons, uas Suav Tebchaws Suav' s khaws cia yog txog 1.9 lab tons, accounting txog li 58% ntawm cov txiaj ntsig thoob ntiaj teb. Tom ntej no tuaj Canada (290,000 tons) thiab Russia (250,000 tons), thaum Tebchaws Meskas tsuas muaj 140,000 tons thiab Tuam Tshoj muaj 13.57 npaug ntawm nws cov peev xwm.
Nws yog tsim nyog teev tias cov ntaub ntawv no thiab kev tshaj tawm hauv tsev tseg rau cov ntaub ntawv sib txawv yog qhov loj heev. Peb yuav tsum paub tias txog rau thaum xaus ntawm xyoo 2018, Tuam Tshoj' s txheeb xyuas tungsten cov peev nyiaj tau nce mus txog 10,715,700 tons. Nws yuav tsum tau piav qhia ntawm no txog USGS cov ntaub ntawv hais txog cov peev ntawm tungsten ore refined rau hauv tungsten ntshiab. Yog li ntawd, nws tsis yog qhov ceeb tias muaj 1,9 lab tons ntawm cov tungsten dawb huv ntxiv tom qab kev tshuaj xyuas thiab rov ua ntawm Tuam Tshoj' s pov thawj tungsten ore.
Raws li xyoo 2016, muaj 14 lub tungsten mines nrog ntau dua 200,000 tons ntawm tungsten hauv ntiaj teb, 10 ntawm lawv nyob hauv peb lub teb chaws. Ganzhou yog qhov chaw yug ntawm Tuam Tshoj' s tungsten kev lag luam. Koj yuav tau hnov ntawm" tsis tshua muaj ntiaj teb lub nceeg vaj" ntawm Ganzhou, uas tsim tawm 70% ntawm lub ntiaj teb' s nruab nrab thiab hauv ntiaj teb tsis tshua muaj hnyav. Tab sis Ganzhou kuj tseem muaj lwm lub npe - tungsten peev thoob ntiaj teb. Txij li thaum tsim cov neeg' s koom pheej ntawm Tuam Tshoj, tungsten cov chaw khaws tseg ntawm no tau mus txog 1,17 lab tons, thiab 60% ntawm lub ntiaj teb' s tungsten tseem tsim nyob rau ntawm no, ua nws cov khoom muaj nqis Cov.
Ntawm tam sim no, ib feem ntau ntawm tungsten tsim nyob rau hauv Suav teb yog siv rau kev xa tawm. Raws li kev txheeb cais, txij xyoo 2015 txog 2019, Tuam Tshoj' s sau tau nqa tawm tungsten cov khoom tau txog 141,000 tons, suav txog kwv yees li ib nrab ntawm kev noj thoob ntiaj teb tungsten. Txawm tias Tebchaws Meskas xav kom xa cov khoom tungsten ntau los ntawm Suav xwb.
Paub txog qhov tseem ceeb thiab kev pheej hmoo ntawm tungsten, xyoo 2018, Asmeskas Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam tau ntxiv tungsten rau nws cov npe ntawm 35 cov zaub mov tseem ceeb, kev tswj hwm thiab khaws cov khoom siv tseem ceeb no ntau dua li kev siv mining. Qhov tseeb, tsis yog Tebchaws Meskas, Tebchaws Europe, Nyij Pooj thiab Kaus Lim Qab Teb thiab lwm lub tebchaws nkaus xwb. Piv txwv, European Union, piv txwv ntxiv tungsten rau nws cov npe ntawm 14 cov zaub mov hauv cov khoom lag luam luv hauv xyoo 2010.
Cov teb chaws no tswj hwm thiab khaws lawv tus kheej tungsten mines, yog li lawv yuav tsum tau coj ntau tungsten, ntau ntawm nws los ntawm Tuam Tshoj. Peb yuav tsum paub tias ntau tshaj 80% ntawm Tuam Tshoj' s xa khoom tungsten tau xa tawm mus rau Tebchaws Europe, Amelikas, Nyij Pooj thiab Kaus Lim Qab Teb, plaub qhov chaw loj. Ua tus neeg tseem ceeb ntawm cov khoom lag luam high-end tungsten, Tebchaws Europe, Amelikas, Nyij Pooj thiab Kaus Lim Qab Teb nyob nruab nrab thiab siab kawg tungsten kev lag luam. Cov khoom siv raw khoom qib tungsten cov khoom lag luam tuaj txawv teb chaws tau ua rau cov khoom lag luam tungsten muaj txiaj ntsig, qee qhov tau siv rau lawv tus kheej siv thiab qee qhov tau raug xa tawm kom tau nyiaj ntau.
Tab sis hmoov tsis zoo, txawm hais tias tungsten ore yog qhov khoom tseem ceeb hauv peb lub teb chaws, tab sis zoo li lub ntiaj teb tsis tshua muaj, tsis tau muag nqi" tsis tshua muaj", tab sis kuj muag cov nqi" hauv ntiaj teb [ GG] quot ;. Vim tias tag nrho cov cuab yeej technology ntawm Tuam Tshoj' s tungsten kev lag luam saw tseem nyob hauv nruab nrab thiab qis kawg, cov khoom lag luam xa tawm feem ntau yog tungsten raw cov khoom lag luam thiab cov khoom tiav ib nrab, nrog tus nqi tsawg ntxiv, thiab tseem muaj qhov tshwm sim ntawm overcapacity, yog li nws tsis tuaj yeem muag ntawm" tus nqi zoo" ;.
Txij xyoo 2011 txog 2016, cov tungsten kev lag luam nyob hauv tebchaws tseem pheej poob qis, tshwj xeeb tshaj yog xyoo 2015, qhov qis tshaj mus rau 50,000 yuan / ton, qhov qis qis dua qhov kev lag luam kev lag luam raug nqi 80,000 yuan rau 85,000 yuan lub sijhawm ntawd. Txawm li cas los xij, kev txhim kho tau tsim nyob rau xyoo tsis ntev los no thiab tungsten mloog zoo tam sim no tau nce mus txog 100,000 100,000 yuan / tuj.
Yog lawm, Tebchaws Europe thiab Asmeskas cov neeg tswj hwm thiab khaws cov khoom tseem ceeb no, thiab peb lub tebchaws yuav tsis muaj qhov tsis nyiam. Qhov tseeb, txij xyoo 2002, Tuam Tshoj tau siv kev tswj hwm tungsten tag nrho, ua ntej lub ntiaj teb tsis tshua muaj; Hauv xyoo 2016, Ministry of Land thiab Cov Khoom Siv tau ntxiv 24 cov zaub mov, suav nrog tungsten thiab lub ntiaj teb tsis tshua muaj, mus rau cov npe ntawm cov cuab yeej zoo txhawm rau txhawm rau txhim kho kev nyab xeeb ntawm cov khoom siv dag zog thiab qib kev tsim kho thiab siv.
Hauv kev tshwj xeeb, Tuam Tshoj' s txoj cai tswj hwm kev xa khoom tawm tshiab tau pib siv thaum lub Kaum Ob Hlis xyoo tas los, thiab Tuam Tshoj' Nws ntseeg tau tias nrog kev koom tes hauv tebchaws thiab nce qib ntawm Tuam Tshoj' s kev hloov pauv kev lag luam thiab kho kom zoo dua, Tuam Tshoj' s tungsten cov khoom siv yuav tau siv kom zoo thiab tsim kho.
