Qhov kev thov ntawm carbide txiav cov cuab yeej ruaj khov, thiab qhov kev thov ntawm cov cuab yeej hnav-tso tawm

Ntawm cov cuab yeej txiav, cemented carbide feem ntau yog siv los ua cov khoom siv txiav, xws li tig lub cuab yeej, milling cutter, planer, laum me ntsis, tho txawv cov cuab yeej, thiab lwm yam nws yog siv rau kev txiav nrum hlau, hlau tsis muaj hlau, plastics, tshuaj fiber, graphite, iav, pob zeb thiab cov hlau zoo tib yam, thiab tseem rau kev txiav cov ntaub ntawv zoo li kub-tsis xeb hlau, stainless hlau, siab manganese steel thiab cuab yeej hlau. Txiav yog feem ntau pom tau hais los ntawm tshuab cuab yeej. Tam sim no, tus nqi ntawm cov cemented carbide siv nyob rau hauv cov cuab yeej txiav tau kwv yees li 1/3 ntawm tag nrho cov khoom lag luam ntawm cemented carbide hauv Suav teb, ntawm 78% yog siv rau cov cuab yeej vuam thiab 22% siv rau cov cuab yeej ntsuas.

Cov cuab yeej txiav yog siv dav hauv kev tsim khoom. Cemented carbide txiav cov cuab yeej siv dav hauv kev kub ceev txiav vim lawv cov khoom zoo (siab zog, siab toughness, siab hardness, zoo thermal stability thiab thermal hard). Downstream tsoos kev lag luam xws li cov tshuab thiab tsheb, nkoj, kev tsheb nqaj hlau, pwm, textile, thiab lwm yam.; siab kawg thiab tawm daim ntawv thov teb suav nrog aerospace, cov ntaub ntawv kev lag luam, thiab lwm yam Ntawm lawv, kev siv tshuab thiab tsheb tsim yog cov ntawv thov tseem ceeb tshaj plaws ntawm cov khoom siv cemented carbide hauv cov hlau txiav.

Ua ntej txhua yam, kev siv tshuab ua cov kev daws teeb meem yog cov khoom tseem ceeb ntawm cemented carbide kev lag luam saw, uas yog taw qhia rau kev nqes dej hauv kev tsim thiab kev ua teb xws li cov cuab yeej siv tshuab CNC, aerospace, kev siv tshuab ua pwm, txua nkoj, khoom siv tshuab marine, thiab lwm yam Raws li cov ntaub ntawv ntawm National Bureau of statistics, xyoo ntawm kev loj hlob ntawm Tuam Tshoj txoj kev lag luam dav dav thiab tshwj xeeb kev lag luam tau thim rov qab rau ob lub xyoo sib law liag tom qab xyoo tawm xyoo 2015. Xyoo 2017, tus nqi tsim tawm ntawm cov khoom siv dav dav tsim kev lag luam yog 4.7 trillion yuan , nrog rau xyoo ntawm lub xyoo nce ntxiv ntawm 8.5%; tus nqi tawm ntawm tshwj xeeb kev tsim khoom siv cuab yeej kev lag luam yog 3.66 trillion yuan, nrog rau lub xyoo nce ntawm 10.20%. Raws li kev nqis peev ruaj khov rau hauv kev tsim khoom lag luam tau tawm hauv qab thiab thim rov qab, qhov kev thov rau cov txheej txheem kev daws teeb meem hauv kev lag luam tshuab yuav rov txuas ntxiv.

Hauv kev tsim kho tsheb, ib qho tseem ceeb tshaj plaws ntawm kev tsim khoom siv hauv lub tsheb yog kev lag luam pwm, thiab cemented carbide tool pwm yog nws qhov tseem ceeb tshaj plaws. Raws li cov ntaub ntawv ntawm National Bureau ntawm cov txheeb cais, Tuam Tshoj qhov kev tsim kho tsheb ntau ntxiv los ntawm 9.6154 lab nyob rau xyoo 2008 txog 29.942 lab nyob rau xyoo 2017, nrog tus nqi nruab nrab ntawm 12.03%. Txawm hais tias qhov kev loj hlob ntawm lub cev muaj peev xwm poob qis hauv ob lub xyoo tsis ntev los no, hauv qab ntawm lub hauv paus ntawm lub hauv paus loj, qhov kev xav tau ntawm kev siv cemented carbide txiav cov cuab yeej hauv cov kho tsheb yuav nyob ruaj khov.

Feem ntau hais lus, hauv thaj teb ntawm kev txiav, kev loj hlob ntawm tsoos tsheb thiab tshuab kev lag luam ruaj khov, thiab qhov kev thov rau cemented carbide kuj ruaj khov. Nws kwv yees tias thaum xyoo 2018-2019, kev siv cov cemented carbide txiav cov cuab yeej yuav ncav cuag 12500 tons thiab 13900 tons feem, nrog kev loj hlob ntawm ntau tshaj ob npaug ntawm tus lej.

Geology thiab mining: xav tau rov qab

Hais txog cov cuab yeej geological thiab cov ntxhia, cemented carbide tsuas yog siv los ua cov cuab yeej zeb pob zeb, cov cuab yeej tsuas thiab cov cuab yeej drilling. Cov ntawv lag luam muaj xws li pob zeb drilling me ntsis rau percussive drilling, laum me ntsis rau kev tshawb nrhiav geological, DTH Laum rau kev khawb thiab roj av, lub khob hliav nyom, kev sib tsoo ntawm cov pob zeb hlais thiab kev cuam tshuam los rau kev tsim cov khoom lag luam. Cemented carbide mining cov cuab yeej ua si lub luag haujlwm tseem ceeb hauv cov thee, roj av, hlau hlau, kev tsim kho vaj tse thiab lwm yam. Kev noj ntawm cov cemented carbide hauv cov cuab yeej geological thiab tsuas yog rau 25% - 28% ntawm lub cev hnyav ntawm cemented carbide.

Tam sim no, Tuam Tshoj tseem nyob hauv nruab nrab theem ntawm kev lag luam, thiab kev loj hlob ntawm kev siv hluav taws xob kev thov qeeb qeeb, tab sis qhov kev thov tag nrho yuav nyob siab. Nws kwv yees tias thaum xyoo 2020, Tuam Tshoj kev siv lub zog hluav taws xob thawj yuav muaj txog 5 billion tons ntawm cov thee pob zeb txheem, 750 lab tons ntawm cov hlau ore, 13,5 lab tons ntawm cov tooj liab ntshiab thiab 35 lab tons ntawm thawj txhuas.

Hauv qab ntawm kev ua haujlwm hauv kev xav tau siab, kev hloov ntawm cov pob zeb hauv av qib ntxiv yuam cov tuam txhab mining kom nce peev siv nyiaj. Piv txwv, cov qhab nia nruab nrab ntawm cov kub ore tso tawm ntawm 10.0 g / T thaum xyoo 1970 mus txog li 1.4 g / T nyob rau xyoo 2017. Qhov no yuav tsum tau nce cov khoom lag luam tawm ntawm cov xim hlau kom thiaj li muaj kev ruaj khov ntawm kev tsim hlau, yog li tsav kev xav tau cov cuab yeej tsuas los sawv.

Hauv ob xyoos tom ntej no, raws li cov nqi ntawm cov thee, roj thiab hlau cov zaub mov tseem nyob siab, nws cia siab tias cov neeg khawb av thiab kev tshawb nrhiav kam kam yuav nce ntxiv, thiab qhov kev thov rau cov cemented carbide rau cov cuab yeej geological thiab mining yuav nce ntxiv. Nws tau cia siab tias qhov kev thov nce qib qov yuav nyob ntawm 20% ntawm 2018-2019.

Hnav cov cuab yeej tiv thaiv: thov kom tso tawm

Hnav resistant cemented carbide feem ntau yog siv nyob rau hauv cov qauv kho tshuab cov khoom siv ntawm ntau cov hnav-tiv tshav teb, suav nrog cov pwm, kev kub siab thiab lub siab qhov chaw siab, hnav qhov chaw-tiv thaiv, thiab lwm yam. Thaum tam sim no, cov cemented carbide siv rau ntau lub pwm kev siv rau txog 8% ntawm tag nrho cov kev tsim tawm ntawm cemented carbide, thiab kab noj hniav rau qhov ua haujlwm siab thiab siab kub tsis kam rau txog 9% ntawm tag nrho cov zis ntawm cemented carbide. Cov cuab yeej siv-tiv taus ntawm no suav nrog, tsis muaj dab tsi, qhia kev tsheb nqaj hlau, plunger, pob, lub log tiv thaiv nplua tus pin, daus scraper phaj, thiab lwm yam.

Nqa cov pwm ua piv txwv, vim yog cov kev lag luam uas siv pwm siv ntau dua, nrog rau kev siv tsheb, khoom siv hauv tsev, nws thiab lwm tus neeg siv khoom lag luam muaj feem cuam tshuam nrog tib neeg lub neej txhua hnub, nyob hauv keeb kwm ntawm kev noj kev haus, kev hloov kho cov khoom lag luam tau nrawm dua thiab zoo dua. , thiab cov tseev kom muaj rau cov pwm kuj tseem siab dua thiab siab dua. Nws tau kwv yees tias qhov kev loj hlob sib xyaw ntawm cov tuag cemented carbide xav tau hauv 2017-2019 yuav txog 9%.

Ntxiv rau, qhov kev thov rau cov cemented carbide rau cov cuab yeej ua haujlwm siab thiab siab kub thiab cov khoom siv coj los tiv thaiv cov khoom hnyav yuav tsum nce los ntawm 14.65% thiab 14.79% feem ntau hauv xyoo 2018-2019, thiab qhov kev thov yuav ncav cuag 11024 tons thiab 12654 tons Cov.
