Ntawm cov cuab yeej txiav, cemented carbide feem ntau yog siv los ua cov cuab yeej cuab tam, xws li tig lub cuab yeej, milling cutter, planer, laum me ntsis, tho txawv cuab yeej, thiab lwm yam. nws yog siv rau txiav cam khwb cia hlau, non-ferrous hlau, yas, tshuaj fiber, graphite, iav, pob zeb thiab cov hlau zoo tib yam, thiab tseem siv rau kev txiav cov khoom siv hluav taws xob xws li cov hlau tsis muaj cua sov, cov hlau tsis muaj steel, siab manganese hlau thiab cov cuab yeej hlau.Txiav yog feem ntau pom tau los ntawm cov cuab yeej siv tshuab.Tam sim no, tus nqi ntawm cov cemented carbide siv rau hauv cov cuab yeej txiav nyiaj li ntawm 1/3 ntawm tag nrho cov khoom ntawm cemented carbide hauv Suav teb, ntawm 78% yog siv rau vuam cov cuab yeej thiab 22% yog siv rau cov cuab yeej indexable.
Cov cuab yeej txiav feem ntau yog siv hauv kev tsim khoom.Cemented carbide tej cuab yeej yog dav siv nyob rau hauv high-ceev txiav vim lawv zoo heev zog (siab zog, siab toughness, siab hardness, zoo thermal stability thiab thermal hardness).Downstream tsoos kev lag luam xws li tshuab thiab tsheb, nkoj, tsheb ciav hlau, pwm, textile, thiab lwm yam.;Cov ntawv thov siab kawg thiab cov ntawv tawm tshiab muaj xws li aerospace, cov ntaub ntawv kev lag luam, thiab lwm yam. Ntawm lawv, cov tshuab thiab tsheb tsim khoom yog cov ntawv thov tseem ceeb tshaj plaws ntawm cov cuab yeej cemented carbide hauv cov hlau txiav.
Ua ntej ntawm tag nrho cov, txhua yam kev daws teeb meem yog cov khoom tseem ceeb ntawm cemented carbide kev lag luam saw, uas yog taw qhia rau downstream manufacturing thiab ua teb xws li CNC tshuab cuab yeej, aerospace, mechanical mold processing, shipbuilding, marine engineering khoom, thiab lwm yam raws li cov ntaub ntawv. ntawm National Bureau of statistics, lub xyoo-rau-xyoo kev loj hlob tus nqi ntawm Tuam Tshoj tus dav dav thiab tshwj xeeb cov cuab yeej tsim kev lag luam tau rebounded rau ob xyoos sib law liag tom qab bottoming tawm nyob rau hauv 2015. Nyob rau hauv 2017, cov zis tus nqi ntawm cov khoom siv dav siv kev lag luam yog 4.7 trillion yuan. , nrog rau lub xyoo nce ntawm 8.5%;Tus nqi tsim tawm ntawm cov cuab yeej tshwj xeeb tsim kev lag luam yog 3.66 trillion yuan, nrog rau xyoo-rau-xyoo nce ntawm 10.20%.Raws li cov cuab yeej cuab tam ruaj khov hauv kev tsim khoom lag luam tau qis dua thiab rov qab los, qhov kev thov rau kev daws teeb meem hauv kev lag luam tshuab yuav rov ua dua ntxiv.
Hauv kev tsim tsheb, ib qho ntawm cov cuab yeej tseem ceeb tshaj plaws hauv kev lag luam tsheb yog cov cuab yeej pwm, thiab cov cemented carbide pwm yog nws cov khoom tseem ceeb tshaj plaws.Raws li cov ntaub ntawv ntawm National Bureau of statistics, Tuam Tshoj tag nrho cov tsheb tsim tau nce los ntawm 9.6154 lab nyob rau hauv 2008 mus rau 29.942 lab nyob rau hauv 2017, nrog ib tug nruab nrab txoj kev loj hlob ntawm 12.03%.Txawm hais tias qhov kev loj hlob zoo li poob qis hauv ob xyoos tsis ntev los no, nyob rau hauv keeb kwm yav dhau los ntawm lub hauv paus siab, kev siv cov cemented carbide txiav cov cuab yeej hauv tsheb yuav nyob ruaj khov.
Feem ntau hais lus, hauv kev txiav, kev loj hlob ntawm cov tsoos tsheb thiab tshuab kev lag luam yog qhov ruaj khov, thiab qhov kev thov rau cemented carbide yog qhov ruaj khov.Nws tau kwv yees tias los ntawm 2018-2019, kev siv cov cemented carbide txiav cov cuab yeej yuav ncav cuag 12500 tons thiab 13900 tons raws li, nrog rau kev loj hlob ntawm ntau tshaj ob tus lej.
Geology thiab mining: thov rov qab
Hais txog cov cuab yeej geological thiab ntxhia, cemented carbide feem ntau yog siv los ua pob zeb drilling cov cuab yeej, cov cuab yeej mining thiab cov cuab yeej drilling.Cov ntaub ntawv muaj xws li pob zeb drilling me ntsis rau percussive drilling, laum me ntsis rau geological tshawb fawb, DTH Laum rau mining thiab oilfield, cone laum, xaiv cov thee cutter thiab cuam tshuam rau kev lag luam cov ntaub ntawv.Cemented carbide mining cov cuab yeej ua lub luag haujlwm tseem ceeb hauv cov thee, roj av, hlau ntxhia, kev tsim kho vaj tse thiab lwm yam.Kev siv cov cemented carbide hauv geological thiab mining cov cuab yeej suav rau 25% - 28% ntawm qhov hnyav ntawm cemented carbide.
Tam sim no, Tuam Tshoj tseem nyob rau hauv nruab nrab theem ntawm industrialization, thiab kev loj hlob tus nqi ntawm cov khoom siv hluav taws xob xav tau qeeb, tab sis tag nrho cov kev thov yuav nyob twj ywm siab.Nws kwv yees tias los ntawm 2020, Tuam Tshoj tus thawj lub zog siv yuav yog li 5 billion tons ntawm cov qauv thee, 750 lab tons ntawm hlau ore, 13.5 lab tons ntawm refined tooj liab thiab 35 lab tons ntawm thawj txhuas.
Raws li keeb kwm yav dhau los ntawm kev ua haujlwm siab, qhov kev poob qis ntawm qib ntxhia ntxiv ua rau cov lag luam mining nce peev kev siv nyiaj.Piv txwv li, qhov nruab nrab qib ntawm cov ore kub poob los ntawm 10.0 g / T nyob rau hauv thaum ntxov 1970s mus txog 1.4 g / T nyob rau hauv 2017. Qhov no yuav tsum tau nce cov zis ntawm raw ore kom muaj kev ruaj ntseg ntawm cov hlau ntau lawm, yog li tsav qhov kev thov. cov cuab yeej mining kom nce.
Nyob rau hauv ob xyoos tom ntej no, raws li cov nqi ntawm cov thee, roj thiab hlau cov zaub mov tseem siab, nws cia siab tias qhov kev txaus siab ntawm kev tshawb nrhiav thiab kev tshawb nrhiav tseem yuav nce ntxiv, thiab qhov kev thov rau cemented carbide rau geological thiab mining cov cuab yeej tseem yuav nce ntxiv.Nws cia siab tias qhov kev thov loj hlob yuav tsum tau khaws cia li ntawm 20% hauv 2018-2019.
Hnav cov khoom siv tiv thaiv: thov tso tawm
Hnav resistant cemented carbide yog tsuas yog siv nyob rau hauv cov khoom siv kho tshuab ntawm ntau yam hnav-resistant teb, nrog rau cov pwm, high-pressure thiab high-temperature kab noj hniav, hnav-resistant qhov chaw, thiab lwm yam. 8% ntawm tag nrho cov zis ntawm cemented carbide, thiab cov kab noj hniav rau kev kub siab thiab kub tsis kam yog kwv yees li 9% ntawm tag nrho cov zis ntawm cemented carbide.Cov khoom hnav-tiv taus muaj xws li nozzle, qhia kev tsheb nqaj hlau, plunger, pob, log tsheb tiv thaiv tus pin, daus scraper phaj, thiab lwm yam.
Siv cov pwm ua piv txwv, vim yog cov kev lag luam uas siv pwm ntau ntxiv, suav nrog tsheb, khoom siv hauv tsev, nws thiab lwm yam kev lag luam uas muaj feem xyuam nrog tib neeg lub neej txhua hnub, nyob rau hauv keeb kwm ntawm kev siv cov khoom siv kho dua tshiab, kev kho dua tshiab ntawm cov khoom lag luam sai dua. , thiab cov kev xav tau rau cov pwm kuj yog siab dua thiab siab dua.Nws tau kwv yees tias qhov sib xyaw ua ke ntawm kev tuag cemented carbide xav tau hauv 2017-2019 yuav yog li 9%.
Tsis tas li ntawd, qhov kev thov rau cemented carbide rau kev kub siab thiab kub resistant kab noj hniav thiab hnav-resistant mechanical yam yuav tsum tau nce los ntawm 14.65% thiab 14.79% raws li nyob rau hauv 2018-2019, thiab qhov kev thov yuav ncav cuag 11024 tons thiab 12654 tons. .
