Monga "mano makampani", simenti carbide chimagwiritsidwa ntchito makampani asilikali, Azamlengalenga, processing makina, zitsulo, pobowola mafuta, zida migodi, mauthenga pakompyuta, zomangamanga ndi zina. Ndi chitukuko cha mafakitale akumunsi, kufunikira kwa msika wa carbide simenti kukukulirakulira. M'tsogolomu, kupanga zida zamakono ndi zipangizo zamakono, kupita patsogolo kwa sayansi ndi luso lamakono, komanso kukula kwachangu kwa mphamvu za nyukiliya kudzawonjezera kwambiri kufunikira kwa zinthu za carbide zokhala ndi teknoloji yapamwamba komanso kukhazikika kwapamwamba. Carbide yokhala ndi simenti imathanso kugwiritsidwa ntchito popangira zida zobowola miyala, zida zamigodi, zida zobowolera, zida zoyezera, zida zokutira zitsulo, mayendedwe olondola, ma nozzles, nkhungu za Hardware, ndi zina zambiri.

Kodi simenti carbide ndi chiyani? Cemented carbide ndi aloyi wopangidwa ndi zinthu zolimba zazitsulo zowuma komanso zomangira zitsulo kudzera muzitsulo za ufa. Ndi ufa zitsulo zopangidwa ndi micron-kakulidwe ufa wa mkulu-kuuma refractory zitsulo carbides (tungsten carbide-WC, titaniyamu carbide-TiC) monga chigawo chachikulu, cobalt (Co) kapena faifi tambala (Ni), molybdenum (Mo) monga chomangira, chotenthetsera mu ng'anjo yopanda vacuum kapena ng'anjo yochepetsera haidrojeni. Ili ndi mndandanda wazinthu zabwino kwambiri monga kuuma kwakukulu, kukana kuvala, mphamvu zabwino ndi kulimba, kukana kutentha, komanso kukana dzimbiri. Makamaka, kuuma kwake kwakukulu ndi kukana kuvala kumakhalabe kosasinthika ngakhale kutentha kwa 500 ° C, ndipo kumakhalabe ndi kuuma kwakukulu pa 1000 ° C. Panthawi imodzimodziyo, ndi chitukuko cha teknoloji yokutira, kukana kuvala ndi kuuma kwa zida za simenti za carbide zapanga kudumpha.

Tungsten ndi gawo lofunikira la zopangira zopangira simenti, ndipo zopitilira 80% za tungsten zimafunikira pakuphatikizika kwa simenti ya carbide. China ndi dziko lomwe lili ndi zinthu zambiri za tungsten padziko lapansi. Malinga ndi data ya USGS, nkhokwe zapadziko lonse lapansi za tungsten ore mu 2019 zinali pafupifupi matani 3.2 miliyoni, pomwe nkhokwe zaku China za tungsten zinali matani 1.9 miliyoni, zomwe zimawerengera pafupifupi 60%; pali makampani ambiri apanyumba opanga ma tungsten carbide, monga Xiamen Tungsten Viwanda, China Tungsten High-tech, Jiangxi Tungsten Viwanda, Guangdong Xianglu Tungsten Viwanda, Ganzhou Zhangyuan Tungsten Viwanda, ndi zina zonse ndi opanga zazikuluzikulu za tungsten carbide, ndi zoperekera ndi zokwanira.

China ndi dziko lomwe lili ndi makina ambiri opangidwa ndi simenti padziko lonse lapansi. Malinga ndi ziwerengero zochokera ku China Tungsten Industry Association, mu theka loyamba la 2022, mabizinesi amtundu wa simenti ya carbide adatulutsa matani 23,000 a carbide yomata, kuwonjezeka kwa chaka ndi 0.2%; adapeza ndalama zazikulu zamabizinesi a yuan biliyoni 18.753, kuwonjezeka kwachaka ndi 17.52%; ndipo adapeza phindu la yuan biliyoni 1.648, kuwonjezeka kwa chaka ndi 22.37%.

Madera ofunikira pamsika wa carbide, monga magalimoto amagetsi atsopano, zidziwitso zamagetsi ndi kulumikizana, zombo, nzeru zopangira, ndege, zida zamakina a CNC, mphamvu zatsopano, nkhungu zazitsulo, zomangamanga, ndi zina zotero, zikukulirakulirabe. Kuyambira 2022, chifukwa cha kusintha kwa zinthu zapadziko lonse lapansi, monga kuchulukira kwa mikangano yachigawo, mayiko a EU, omwe ndi gawo lofunika kwambiri pakupanga ndi kugwiritsa ntchito simenti ya carbide padziko lonse lapansi, awona kuwonjezeka kwakukulu kwa mtengo wamagetsi opangira simenti ndi ndalama zogwirira ntchito. chifukwa chakukwera kwamitengo yamagetsi. China idzakhala chonyamulira chofunikira pakusamutsa makampani ake opangidwa ndi simenti ya carbide.
