Tuam Tshoj txoj kev noj tungsten hauv tsev tau nyob ruaj khov ntawm kwv yees li 10,000 tons / xyoo.Raws li tsab ntawv ceeb toom, kev noj tungsten hauv Suav teb yog 9,200 tons, 9,400 tons thiab 9,500 tons hauv 1994-1996, thiab kev noj tungsten hauv Suav teb tau kwv yees tias yuav yog 11,500 tons hauv 2000. Txij li xyoo 1980s, kev noj cov qauv ntawm tung. Tuam Tshoj tau ua ntsiag to hloov.Kev txheeb cais qhia tau hais tias los ntawm 1980 txog 1985, kev siv cov qauv ntawm tungsten rau steelmaking suav txog 61% ntawm tag nrho cov kev siv, suav rau qhov loj tshaj plaws;Los ntawm 1986 txog 1990, qhov kev faib ua feem ntawm tungsten siv hauv steelmaking poob mus rau 48%, thaum feem ntawm tungsten siv hauv cemented carbide nce mus rau 28%.Los ntawm 1991 mus rau 1995, raws li cov zis ntawm cemented carbide nce siab, qhov feem ntawm tungsten siv nyob rau hauv cemented carbide ntau tshaj li ntawm tungsten siv nyob rau hauv steelmaking, nce mus txog 50% ntawm tag nrho cov domestic tungsten noj, thaum lub feem pua ntawm cov tungsten siv nyob rau hauv steelmaking poob mus txog. 40%.
Nws yog pom tseeb tias qhov kev hloov ntawm tungsten noj qauv hauv Suav teb yog ncaj qha ntsig txog kev tsim cov cemented carbide.Yog li, dab tsi yog qhov sib txawv ntawm Tuam Tshoj cov cemented carbide ntau lawm?Tam sim no tus qauv ntawm carbide ntau lawm hauv Suav teb.
Suav tebcemented carbidekev lag luam pib nyob rau hauv nruab nrab-1950s, thiab txawm hais tias lub industrial system tau tsim nyob rau hauv peb caug xyoo tom qab tshaj nyob rau hauv lub tsim lub teb chaws ntawm lub East thiab West, qhov ceev ntawm nws txoj kev loj hlob thiab lub scale ntawm nws cov khoom tau zoo kawg li rau lub ntiaj teb no.Tshwj xeeb tshaj yog nyob rau xyoo 1990, nyob rau hauv kev hloov kho thiab qhib thiab kev lag luam-taw qhia kev lag luam, cov txiaj ntsig ntawm cemented carbide tau nce siab.Tam sim no, muaj 150 cemented carbide manufacturers hauv Suav teb, nrog rau tag nrho cov peev txheej ntawm 9,000-10,000 tons / xyoo.Tag nrho cov khoom lag luam txhua xyoo yog kwv yees li 7000-7500 tons, suav txog 21% ntawm lub ntiaj teb tag nrho cov khoom lag luam txhua xyoo, uas yog ntau dua li Tebchaws Meskas, Sweden, CIS thiab lwm lub tebchaws uas muaj ntau tshaj cemented carbide kev lag luam hauv kev tsim khoom thaum ntxov thiab lub ntiaj teb thawj zaug. .Thaum lub sij hawm 8th Tsib Xyoo Plan, qhov nruab nrab txhua xyoo ntawm cemented carbide nyob rau hauv Tuam Tshoj yog 6528 tons (qhov ntau tshaj txhua xyoo yog 7540 tons hauv 1994), thiab qhov nruab nrab txhua xyoo noj yog 5894 tons (qhov siab tshaj plaws txhua xyoo noj yog 6620 tons) .Raws li cov kws tshaj lij kev twv ua ntej, thaum lub sijhawm Ninth Tsib Xyoo Plan, qhov nruab nrab txhua xyoo ntawm cov cemented carbide hauv Suav teb yuav nce 6%, piv txwv li, qhov nruab nrab txhua xyoo ntau lawm yuav ncav cuag 6976 tons.Qee cov kws tshaj lij siv cov kab sib txuas sib txuas los txuas cov hlau thiab cemented carbide ntau lawm hauv Suav teb thaum lub Cuaj Hlis Tsib Xyoo.Cov lej simulation tau ua tiav los suav ob qhov ntsuas ntawm GDP.
Thib peb, kev rov ua dua thiab siv cov pov tseg thiab cov seemcarbideraws li ib txoj hauv kev los ntxiv qhov tsis txaus ntawm cov peev txheej ntuj
Cov peev txheej ntuj raug txwv, thiab lub tswb nrov ntawm kev poob qhov zoo ntawm cov peev txheej tungsten tau nrov nrov hauv peb pob ntseg.Nyob rau hauv lub ntsej muag ntawm qhov xwm txheej txaus ntshai no, cov kws tshaj lij tau tsim ntau yam kev tiv thaiv thiab kev daws teeb meem.Ntawm lawv, cov txheej txheem ntawm kev rov ua dua tshiab thiab siv cov khoom seem tungsten carbide tau ua pov thawj tias yog ib qho kev paub tab, siv tau thiab siv tau.Nws yog ib txoj hauv kev zoo los txo tus nqi ntawm cov khoom siv carbide thaum lub sij hawm muaj ntau cov khoom nyoos tungsten, thiab ib qho tseem ceeb los ua kom tsis muaj peev txheej tam sim no thiab yav tom ntej thaum ntuj raw tungsten yog depleted.Qhov kev siv dav dav ntawm kev siv cov khoom siv rov ua dua tshiab yog ib qho ntawm cov cim tseem ceeb ntawm kev txhim kho thev naus laus zis thiab kev txhim kho kev lag luam ntawm lub teb chaws thiab kev lag luam.Qhov tseeb, cov teb chaws tsim kho nyob rau sab hnub tuaj thiab sab hnub poob tau suav nrog kev rov ua dua tshiab thiab siv cov khoom siv khib nyiab pov tseg hauv cov khoom qub.Tam sim no, lawv cov khoom siv rov ua dua tshiab thiab siv cov seem seem cemented carbide tau mus txog 30-40% ntawm tag nrho cov khoom tsim tawm txhua xyoo.Tuam Tshoj txoj kev noj txhua xyoo ntawm tungsten hlau yog kwv yees li 10,000 tons, yog tias nws tuaj yeem ncav cuag 40% ntawm kev rov ua dua tshiab, nws cov txiaj ntsig kev lag luam thiab cov peev txheej ntxiv yuav muaj txiaj ntsig zoo.Siv cov cemented carbide ua piv txwv, tag nrho cov txiaj ntsig ntawm cemented carbide hauv Suav teb xyoo 1994 yog 7540 tons, raws li kev suav ntawm 40% rov qab, tsis yog peb tuaj yeem rov qab tau ze li ntawm 3000 tons ntawm tungsten hlau, tab sis kuj muaj ze li ntawm 240 tons ntawm cobalt hlau. .Raws li kev suav ntawm kev siv 2 tons ntawm tungsten mloog zoo rau txhua 1 tuj ntawm cemented carbide tsim, kev noj ntawm tungsten concentrate yuav raug txo los ntawm ze li ntawm 6000 tons.Qhov no yuav tsis ua rau muaj lub luag haujlwm loj hauv kev daws qhov tsis txaus ntawm cov peev txheej.Qhov teeb meem yooj yim ntawm kev rov ua dua thiab siv cov khoom seem carbide hauv Suav teb tam sim noCov seem carbide seem peb xa mus rau ntawm no suav nrog ob ntu: ib qho yog cov khoom tsis tsim nyog hauv cov txheej txheem tsim khoom;Lwm qhov yog siv cov khoom siv khib nyiab carbide (cov hniav, brazing hau, pwm, thiab lwm yam).
Raws li kev txheeb cais tsis tiav, tag nrho tus nqi ntawmresidual carbidegenerated nyob rau hauv Tuam Tshoj yog hais txog 3500 tons ib xyoo.Raws li cov tuam txhab txawv teb chaws carbide, ntawm cov cuab yeej siv cov khoom siv carbide, feem ntau hais lus, 12-25% ntawm cov seem vuam ntxig tuaj yeem rov ua dua;65-70% ntawm cov khoom seem carbide tuag (punching tuag, nias tuag, kos duab tuag, thiab lwm yam) tuaj yeem rov ua dua;95-97% ntawm lub tshuab scraping inserts tuaj yeem rov ua dua.
Tuam Tshoj tau pib rov siv dua thiab siv cov khoom seem carbide lig.Xyoo 1983, qhov ntim rov ua dua tsuas yog 300 tons, suav txog 8% ntawm cov khoom tsim tawm hauv xyoo ntawd;xyoo 1985, nws tau nce mus rau ntau dua 400 tons, suav txog 10% ntawm cov khoom tsim tawm hauv xyoo ntawd.accounting rau 10% ntawm cov khoom tsim nyob rau xyoo ntawd.Nyob rau hauv lub nineties, txoj hauj lwm rov ua dua tshiab tau muaj kev txhim kho ntau dua.Tam sim no muaj ntau tshaj 150 cemented carbide manufacturers nyob rau hauv lub teb chaws, tsis tsuas yog ze li ntawm 60 me me thiab nruab nrab factories muaj tungsten raw cov ntaub ntawv los ntawm recycled cov kev pab cuam, uas yog, nrog rau cov nplai ntawm Zhuzhou Cemented Carbide Factory thiab Zigong Cemented Carbide Limited Liability Company. (yav tas los Zigong Cemented Carbide Factory) kuj tau qhib cov kab ntau lawm ntawm cov khoom siv pov tseg cov cemented carbide.Tam sim no, lub teb chaws rov ntim ntim yog siab dua 1500 tons, uas suav txog li 20% lossis ntau dua ntawm tag nrho cov khoom siv cemented carbide hauv Suav teb thiab ze rau qib ntawm Nyiv.Cov txheej txheem thev naus laus zis ntawm kev rov ua dua cov seem seem cemented carbide yog ua tiav,?s txheej txheem ntawm zinc melting txoj kev, hluav taws xob melting txoj kev thiab mechanical crushing txoj kev yog mastered.Cov khoom siv rov ua dua tshiab tungsten carbide hmoov (WC) thiab cobalt hmoov (Co), uas yog cov zoo heev, tuaj yeem siv rau kev tsim cov carbide, pob zeb diamond dag, cov khoom siv hlau thiab lwm yam khoom.Muaj ob peb cheeb tsam uas cov khoom siv rov ua dua tshiab thiab rov ua dua tshiab, cov uas yog: Zhuzhou thiab Changsha hauv Hunan;Zigong hauv Sichuan;Qinghe hauv Hebei Xeev;Jinan hauv xeev Shandong;Mudanjiang hauv xeev Heilongjiang, thiab lwm yam. Cemented carbide manufacturers nyob rau hauv cov cheeb tsam no tau ua tiav kev ua tau zoo ntawm recycling thiab siv cov seem seem cemented carbide.
