Cov ntaub ntawv tshawb fawb tshiab ntxiv los ntawm kev tshawb fawb kev lag luam, cam khwb cia hlau thiab cam khwb cia hlau casting lag luam nrog Covid-19 cuam tshuam kev tshuaj xyuas
Cam khwb cia hlau yog ib pawg ntawm cov hlau-carbon alloys nrog cov ntsiab lus carbon ntau dua 2%.Nws cov txiaj ntsig yog los ntawm nws qhov qis melting kub.Cov alloy muaj pes tsawg leeg yuav cuam tshuam rau nws cov xim thaum nws tawg: dawb cam khwb cia hlau muaj carbide impurities, cia cov kab nrib pleb kom dhau mus ncaj qha;grey cam khwb cia hlau muaj graphite flakes, uas muaj peev xwm deflect hla cov kab nrib pleb thiab pib countless tshiab tawg raws li cov khoom tawg;Thaum cov hlau tsis muaj hlau muaj Spherical graphite "nodules" tiv thaiv cov kab nrib pleb los ntawm kev txhim kho ntxiv.Hauv 2019, kev lag luam cov nyiaj tau los ntawm cov hlau cam khwb cia hlau thiab cam khwb cia hlau yog xx.xx lab nyiaj daus las thiab yuav ncav cuag xx.xx lab nyiaj daus las los ntawm 2025. Qhov sib xyaw ua ke txhua xyoo kev loj hlob ntawm 2020-2025 yog xx%.
Hauv cov ntsiab lus ntawm kev sib kis thoob ntiaj teb COVID-19, daim ntawv tshaj tawm no muab kev tshuaj xyuas 360-degree, los ntawm cov saw hlau xa khoom, kev tswj hwm thiab xa tawm mus rau tsoomfwv cov cai hauv cheeb tsam thiab kev cuam tshuam yav tom ntej ntawm kev lag luam.Kev soj ntsuam ntxaws ntxaws ntawm kev ua lag luam (2015-2020), cov qauv kev sib tw ntawm cov tuam txhab, cov khoom lag luam muaj zog thiab qhov tsis muaj zog, kev txhim kho kev lag luam (2020-2025), cov qauv kev lag luam hauv cheeb tsam thiab kev lag luam macroeconomic, kev lag luam cov cai.Kev tshawb fawb los ntawm cov khoom siv raw mus rau cov neeg siv khoom kawg hauv kev lag luam tseem yuav qhia txog cov ncauj lus ntawm cov khoom lag luam thiab cov khoom muag.Nrog rau COVID-19 hauv siab, daim ntawv tshaj tawm no muab kev txheeb xyuas dav dav thiab tob tob txog seb tus kabmob kis tau zoo li cas rau kev hloov pauv thiab hloov pauv ntawm kev lag luam no.
Hauv COVID-19 qhov tshwm sim, Tshooj 2.2 ntawm tsab ntawv tshaj tawm no txheeb xyuas qhov cuam tshuam ntawm COVID-19 rau kev lag luam thoob ntiaj teb thiab kev lag luam cam khwb cia hlau thiab cam khwb cia hlau.Tshooj 3.7 txheeb xyuas qhov cuam tshuam ntawm COVID-19 los ntawm qhov kev xav ntawm kev lag luam saw.Tsis tas li ntawd, Tshooj 7-11 tseem xav txog qhov cuam tshuam ntawm COVID-19 rau kev lag luam hauv cheeb tsam.
Kev lag luam cam khwb cia hlau thiab cam khwb cia hlau tuaj yeem muab faib ua cov khoom lag luam, cov ntawv thov tseem ceeb thiab cov teb chaws tseem ceeb / cheeb tsam raws li hauv qab no:
Tshooj 12 qhia txog cov neeg tseem ceeb hauv ntiaj teb cam khwb cia hlau thiab cam khwb cia hlau castings lag luam: * Grupo Industries, Saltillo * Dakota Foundry * MES, Inc. * ACAST * Hitachi hlau * Qingdao Tianhua Yihe Foundry * Huadong Tek West Sen Iron Foundry * Foundatur Casting * Hindusja Casting * Elkem * Grede tuav * Brantingham Manufacturing * India Nres Co., Ltd. * Dalle (Durham) Casting * Anhui Yingliu Group (AOSCO Industries) * Benton (Benton) Casting
Hauv Tshooj 4 thiab Tshooj 14.1, raws li hom, cam khwb cia hlau thiab cam khwb cia hlau casting lag luam los ntawm 2015 txog 2025 feem ntau muab faib ua: * Grey cam khwb cia hlau * Cov hlau cam * Malleable cam khwb cia hlau
Hauv Tshooj 5 thiab Tshooj 14.2, nyob ntawm daim ntawv thov, cam khwb cia hlau thiab cam khwb cia hlau casting lag luam los ntawm 2015 txog 2025 npog: * tsheb * kev lag luam machinery * kev tsim kho thiab kev tsim kho tshuab * hluav taws xob
Geographically, Tshooj 6, 7, 8, 9, 10, 11, thiab 14 hais txog kev noj, nyiaj tau los, kev lag luam thiab kev loj hlob ntawm cov cheeb tsam hauv qab no, kev tshuaj xyuas ntxaws txog keeb kwm thiab kev kwv yees (2015-2025):
