Pakati zida kudula, simenti carbide zimagwiritsa ntchito ngati zida kudula zida, monga kutembenuza chida, mphero wodula, planer, kubowola pang'ono, chida wotopetsa, etc. ndi ntchito kudula kuponya chitsulo, zitsulo sanali ferrous, mapulasitiki, mankhwala CHIKWANGWANI, graphite, galasi, mwala ndi zitsulo wamba, komanso kudula zipangizo refractory monga zitsulo zosagwira kutentha, zitsulo zosapanga dzimbiri, mkulu manganese chitsulo ndi chida zitsulo.Kudula kumachitika makamaka ndi zida zamakina.Pakalipano, kuchuluka kwa carbide yopangidwa ndi simenti yomwe imagwiritsidwa ntchito podulira zida ndi pafupifupi 1/3 ya carbide yonse yopangidwa ndi simenti ku China, yomwe 78% imagwiritsidwa ntchito popangira zida zowotcherera ndipo 22% imagwiritsidwa ntchito pazida zolozera.
Zida zodulira zimagwiritsidwa ntchito makamaka popanga.Zida zodulira simenti za carbide zimagwiritsidwa ntchito kwambiri podula mwachangu chifukwa cha zinthu zabwino kwambiri (zamphamvu kwambiri, zolimba kwambiri, zolimba kwambiri, kukhazikika kwamafuta komanso kulimba kwamafuta).Mafakitale azikhalidwe zakutsika monga makina ndi magalimoto, sitima, njanji, nkhungu, nsalu, etc.;mkulu mapeto ndi akutuluka ntchito minda monga Azamlengalenga, makampani zambiri, etc. Pakati pawo, makina ndi galimoto kupanga ndi zofunika kwambiri ntchito minda ya simenti zida carbide mu kudula zitsulo.
Choyamba, njira zothetsera mawotchi ndizomwe zimagwiritsidwa ntchito pamakampani opanga cemented carbide, zomwe zimayang'ana kumunsi kwa minda yopangira ndi kukonza zinthu monga CNC makina, ndege, makina opangira nkhungu, kupanga zombo, zida zaumisiri zam'madzi, etc. Malinga ndi deta. wa National Bureau of statistics, chaka ndi chaka chiwongolero cha kukula kwa mafakitale aku China ndi zida zapadera zopangira zida zawonjezeka kwa zaka ziwiri zotsatizana pambuyo pomaliza ku 2015. , ndi kuwonjezeka kwa chaka ndi chaka ndi 8.5%;mtengo wamakampani opanga zida zapadera unali 3.66 thililiyoni yuan, ndikuwonjezeka kwa chaka ndi 10.20%.Pomwe ndalama zosasunthika m'makampani opanga zida zatsika ndikuwonjezereka, kufunikira kwa mayankho pamakina am'makina kumachulukirachulukira.
Pakupanga magalimoto, chimodzi mwazinthu zofunika kwambiri pamakampani opanga magalimoto ndi nkhungu ya zida, ndipo nkhungu ya zida za simenti ya carbide ndiye gawo lofunikira kwambiri.Malinga ndi data ya National Bureau of Statistics, magalimoto onse aku China adakwera kuchoka pa 9.6154 miliyoni mu 2008 kufika pa 29.942 miliyoni mu 2017, ndikukula kwapakati pa 12.03%.Ngakhale kukula kukucheperachepera zaka ziwiri zaposachedwa, pansi pa maziko apamwamba, kufunikira kwa zida zodulira simenti ya carbide m'munda wamagalimoto kumakhalabe kokhazikika.
Nthawi zambiri, pankhani yodula, kukula kwa magalimoto azikhalidwe zamagalimoto ndi makina kumakhazikika, ndipo kufunikira kwa simenti ya carbide ndikokhazikika.Akuti pofika chaka cha 2018-2019, kugwiritsa ntchito zida zodulira simenti za carbide kudzafika matani 12500 ndi matani 13900 motsatana, ndikukula kwa manambala opitilira awiri.
Geology ndi migodi: amafuna kuchira
Pankhani ya zida za geological ndi mineral, carbide yokhazikika imagwiritsidwa ntchito makamaka ngati zida zoboola miyala, zida zamigodi ndi zida zobowolera.Mitundu yazinthuzo ndi monga pobowola miyala pobowola percussive, kubowola pofufuza za geological, DTH Drill for mining and oilfield, cone drill, pick of malasha cutter and impact drill for building materials.Zida za migodi ya simenti ya carbide zimagwira ntchito yofunika kwambiri pamakala, petroleum, mchere wazitsulo, zomangamanga ndi zina.Kugwiritsa ntchito simenti ya carbide mu zida za geological ndi migodi ndi 25% - 28% ya kulemera kwa simenti ya carbide.
Pakalipano, China idakali pakati pa mafakitale, ndipo kukula kwa kufunikira kwa mphamvu zamagetsi kukucheperachepera, koma chiwerengero chonsecho chidzakhalabe chachikulu.Akuti pofika chaka cha 2020, kugwiritsa ntchito mphamvu ku China kudzakhala pafupifupi matani 5 biliyoni a malasha, matani 750 miliyoni achitsulo, matani 13.5 miliyoni amkuwa woyengedwa ndi matani 35 miliyoni a aluminiyamu yoyambirira.
Pansi pa ntchito yofunikira kwambiri, kutsika kwa ma mineral grade kumapangitsanso mabizinesi ang'onoang'ono kuti achulukitse ndalama zazikulu.Mwachitsanzo, pafupifupi golide wa ore adatsika kuchokera ku 10.0 g / T koyambirira kwa zaka za m'ma 1970 kufika pafupifupi 1.4 g / T mu 2017. Izi ziyenera kuonjezera kutuluka kwa miyala yaiwisi kuti zikhalebe zokhazikika pakupanga zitsulo, motero kuyendetsa kufunika zida zamigodi kukwera.
M'zaka ziwiri zikubwerazi, monga mitengo ya malasha, mafuta ndi zitsulo mchere kukhalabe mkulu, zikuyembekezeredwa kuti migodi ndi kufufuza kufunitsitsa kupitiriza kukwera, ndi kufunika simenti carbide zida geological ndi migodi adzapitiriza kuwonjezeka kwambiri.Zikuyembekezeka kuti kuchuluka kwa kufunikira kudzasungidwa pafupifupi 20% mu 2018-2019.
Valani zida zosagwira ntchito: kumasulidwa kofunikira
Kuvala kugonjetsedwa ndi simenti carbide makamaka ntchito makina kapangidwe zinthu zosiyanasiyana kuvala zosagwira minda, kuphatikizapo nkhungu, mkulu-anzanu ndi mkulu-kutentha patsekeke, kuvala zosagwira mbali, etc. Pakali pano, simenti carbide ntchito zosiyanasiyana nkhungu nkhani pafupifupi 8% ya okwana linanena bungwe simenti carbide, ndi patsekeke kwa kuthamanga kwambiri ndi mkulu kutentha kukana nkhani pafupifupi 9% ya okwana linanena bungwe carbide simenti.Magawo osamva kuvala amaphatikizapo nozzle, njanji yowongolera, plunger, mpira, pini yotsutsa-skid tayala, mbale ya snow scraper, ndi zina.
Kutengera nkhungu mwachitsanzo, chifukwa cha mafakitale omwe amagwiritsa ntchito nkhungu mwamphamvu kwambiri, kuphatikiza magalimoto, zida zapakhomo, ndi mafakitale ena ogula omwe amagwirizana kwambiri ndi moyo watsiku ndi tsiku wa anthu, chifukwa cha kukweza kwa mowa, kukonzanso kwa zinthu kumathamanga komanso mwachangu. , ndipo zofunikira za nkhungu zimakhalanso zapamwamba komanso zapamwamba.Akuti kukula kwaphatikizidwe kwa kufa simenti ya carbide mu 2017-2019 kudzakhala pafupifupi 9%.
Kuphatikiza apo, kufunikira kwa carbide yokhala ndi simenti yamabowo othamanga kwambiri komanso kutentha kwambiri komanso zida zamakina osavala zikuyembekezeka kukwera ndi 14.65% ndi 14.79% motsatana mu 2018-2019, ndipo kufunika kudzafika matani 11024 ndi matani 12654. .
