Kufunika kwa zida zodulira carbide ndikokhazikika, ndipo kufunikira kwa zida zosagwira kumatulutsidwa

Pakati zida kudula, carbide simenti zimagwiritsa ntchito ngati kudula zipangizo, monga kutembenukira chida, mphero wodula, planer, kubowola pang'ono, chida wotopetsa, etc.gwiritsidwa ntchito kudula chitsulo chosungunula, zitsulo sanali akakhala, mapulasitiki, CHIKWANGWANI mankhwala, graphite, galasi, mwala ndi chitsulo wamba, komanso kudula zinthu zopangira monga chitsulo chosagwira kutentha, chitsulo chosapanga dzimbiri, chitsulo cha manganese chachikulu ndi chitsulo chachitsulo. Kudula makamaka anazindikira ndi zida makina. Pakadali pano, kuchuluka kwa carbide wokhala ndi simenti wogwiritsidwa ntchito pocheka zida kumawerengera pafupifupi 1/3 yazinthu zonse zopangidwa ndi simenti ku China, 78% yake imagwiritsidwa ntchito pazida zowotcherera ndipo 22% imagwiritsidwa ntchito pazida zosakika.

Zida zochepetsera zimagwiritsidwa ntchito popanga. Zida zodulira carbide zimagwiritsidwa ntchito pocheka mwachangu kwambiri chifukwa cha zida zawo zabwino kwambiri (mphamvu yayikulu, kulimba kwambiri, kuuma kwakukulu, kukhazikika kwamafuta abwino komanso kulimba kwamafuta). Kumunsi kwa mafakitale achikhalidwe monga makina ndi galimoto, sitima, njanji, nkhungu, nsalu, ndi zina; Mapeto ake komanso ntchito zomwe zikubwera zikuphatikizapo malo osungira zinthu, makampani azidziwitso, ndi zina zambiri. Pakati pawo, makina ndi makina opanga magalimoto ndi malo ofunikira kwambiri pazida zolimbitsa carbide pakudula kwazitsulo.

Choyambirira, njira zamagetsi zamagetsi ndizomwe zimapangidwa ndi simenti yamafuta a carbide, omwe amayang'ana kutsika kwa zinthu zopangira ndi kukonza monga zida za makina a CNC, malo osungira zinthu, makina opanga nkhungu, zomangamanga, zida zomangamanga zam'madzi, ndi zina zambiri. wa National Bureau of Statistics, kuchuluka kwa chaka ndi chaka pamakampani opanga zida zapadera zaku China komanso zida zapadera zachulukanso kwa zaka ziwiri zotsatizana zitatuluka mu 2015. Mu 2017, phindu la mafakitale opanga zida zonse linali 4.7 trilioni yuan , ndikuwonjezeka kwa chaka ndi chaka kwa 8.5%; phindu la mafakitale opanga zida zapadera linali yuan 3.66 trilioni, ndikuwonjezeka kwa chaka ndi chaka kwa 10.20%. Monga kukhazikika kwachuma m'makampani opanga kwatsika ndikuchulukirachulukira, kufunika kokonza njira zothetsera vuto pamakina kukuwonjezekanso.

Kupanga magalimoto, chimodzi mwazida zofunikira kwambiri pamakampani opanga magalimoto ndi nkhungu yazida, ndipo zida zomangira carbide ndizofunikira kwambiri. Malinga ndi kafukufuku wa National Bureau of Statistics, makina opanga magalimoto ku China adakwera kuchoka pa 9.6154 miliyoni mu 2008 mpaka 29.942 miliyoni mu 2017, ndikukula kwapakati pa 12.03%. Ngakhale kuchuluka kwakuchulukirachulukira kumachepa mzaka ziwiri zapitazi, titakhazikika kwambiri, kufunika kwa zida zodulira carbide yolimba pamunda wamagalimoto kudzakhalabe kolimba.

Kunena zambiri, pamunda wodula, kuchuluka kwakukula kwamakampani agalimoto ndi makina ndikukhazikika, ndipo kufunikira kwa carbide yolimbitsa sikukhazikika. Akuyerekeza kuti pofika 2018-2019, kumwa zida zomangira carbide yolimbitsa thupi kudzafika matani 12500 ndi matani 13900 motsatana, ndikukula kwakukula manambala opitilira kawiri.

Geology ndi migodi: amafuna kuchira

Kumbali ya zida za geological ndi mchere, carbide wokhala ndi cemented imagwiritsidwa ntchito ngati zida zobowolera miyala, zida zamigodi ndi zida zobowolera. Mitundu yazopangidwayi ikuphatikizira pobowola miyala, pobowola pobowola nthaka, kubowola kwa DTH kwa migodi ndi malo amafuta, kubowola kwa cone, kusankha kwa wodula malasha ndi kubowola kwakomwe kumakampani opanga zida zomangamanga. Zida zamchere za carbide zolimba zimathandiza kwambiri pamafuta amafuta, mafuta amchere, mchere wazitsulo, zomangamanga ndi zina. Kugwiritsa ntchito simenti ya carbide mu zida za geological ndi migodi kumawerengera 25% - 28% ya kulemera kwa carbide wolimba.

Pakadali pano, China ikadali pakatikati pa mafakitale, ndipo kuchuluka kwa mphamvu zamagetsi kukucheperachepera, koma zofunikira zonse zizikhala zazikulu. Akuyerekeza kuti pofika chaka cha 2020, mphamvu zoyambira ku China zikhala pafupifupi matani 5 biliyoni amakala amoto, matani 750 miliyoni achitsulo, matani 13.5 miliyoni amkuwa woyengedwa ndi matani 35 miliyoni a aluminium yoyambirira.

Pomwe ntchito ikufunidwa kwambiri, kuchepa kwa magwiridwe antchito kumalimbikitsanso mabizinesi amigodi kuti azigwiritsa ntchito ndalama zambiri. Mwachitsanzo, avareji ya miyala ya golide idatsika kuchoka pa 10.0 g / T koyambirira kwa ma 1970 mpaka pafupifupi 1.4 g / T mu 2017. Izi zikuyenera kukulitsa kutulutsa kwa miyala yosaphika kuti pakhale kukhazikika kwapangidwe kazitsulo, ndikupangitsa kufunikira kwa zida zamigodi kuti ziwuke.

M'zaka ziwiri zikubwerazi, mitengo yamakala amafuta, mafuta ndi chitsulo ikadali yokwera, zikuyembekezeredwa kuti kufunitsitsa kwa migodi ndi kufufuzira kupitilirabe kukwera, ndipo kufunikira kwa carbide wolimba wa zida za geological ndi migodi kupitilirabe kukwera kwambiri. Zikuyembekezeka kuti chiwongola dzanja chidzasungidwa pafupifupi 20% mu 2018-2019.

Valani zida zosagonjetsedwa: kutulutsa kofunikira

Valani carbide yosagwiritsidwa ntchito makamaka imagwiritsidwa ntchito popanga makina osiyanasiyana, kuphatikizapo nkhungu, kuthamanga ndi kutentha, mbali zosavala, ndi zina zambiri. Pakadali pano, carbide yolumikizidwa yomwe imagwiritsidwa ntchito pazinthu zingapo za nkhungu 8% yazotulutsa zonse za carbide wokhala ndi cement, komanso mphako yothamanga kwambiri komanso kutentha kwambiri imapangitsa pafupifupi 9% ya chiwonkhetso cha carbide wamatope. Zida zosagwira ndizophatikizira nozzle, njanji yowongolera, plunger, mpira, tayala yolimbana ndi skid, mbale yopanda chisanu, ndi zina zambiri.

Kutenga nkhungu monga chitsanzo, chifukwa cha mafakitale omwe amagwiritsa ntchito nkhungu molimbika kwambiri, kuphatikiza magalimoto, zida zapanyumba, izo ndi mafakitale ena ogula omwe amagwirizana kwambiri ndi moyo wa anthu watsiku ndi tsiku, potengera kukonzanso kwa zakumwa, kukonzanso kwa zinthu kumakhala mwachangu komanso mwachangu , Zofunikira pa nkhungu zimakhalanso zapamwamba. Akuyerekeza kuti kuchuluka kwakukula kwakufa kwa cemented carbide wofunidwa mu 2017-2019 kudzakhala pafupifupi 9%.

Kuphatikiza apo, kufunika kwa carbide wokhala ndi simenti wothinikizika kwambiri komanso zotchinga zotentha komanso zida zosagwiritsa ntchito makina zikuyembekezeka kuwonjezeka ndi 14.65% ndi 14.79% motsatana mu 2018-2019, ndipo kufunika kudzafika matani 11024 ndi matani 12654 .
