Zida zapamwamba za carbide zokhala ndi simenti zimaperekedwa paokha, ndipo "mano" a makina opanga mafakitale ndi amphamvu.

Pa makina osindikizira a servo, mkono wamakina umapitilira kuvina. Pasanathe sekondi imodzi, ufa wa imvi-wakuda umaponderezedwa ndikupangidwa kukhala tsamba la kukula kwa chikhadabo.

Ichi ndi CNC chida, lotchedwa "mano" a mafakitale mayi makina-m'mimba mwake ya yaying'ono kubowola pokha ndi zabwino monga 0,01 mm, amene akhoza "wopeta" 56 zilembo Chinese pa njere ya mpunga; Chida chobowola ndi chotakata ngati tayala, chomwe chimatha kudya dothi lofewa komanso kutafuna thanthwe lolimba, ndipo chimagwiritsidwa ntchito pamutu wodula wa makina achitetezo opangidwa kunyumba kwambiri "Juli No. 1".

Pali dziko mu chida chaching'ono. Kulimba kwa "mano achitsulo ndi mano amkuwa" kumachokera ku carbide yopangidwa ndi simenti, yomwe ili yachiwiri kwa diamondi pakuuma.

M'makampani opanga mafakitale, zida ndizomwe zimagwiritsidwa ntchito. Pokhapokha akakhala olimba mokwanira kuti azitha kupirira; pokhapokha atakhala amphamvu mokwanira sangathe kusweka; ndipo kokha pamene ali olimba mokwanira angathe kukana kukhudzidwa. Poyerekeza ndi zida zachitsulo zachikhalidwe, zida za carbide zokhala ndi simenti zimakhala ndi liwiro lodulira lomwe limathamanga nthawi 7 komanso moyo wautumiki womwe utha kuwonjezedwa pafupifupi nthawi 80.

Chifukwa chiyani choyikapo simenti cha carbide "chosawonongeka"?

Yankho likhoza kupezeka mu tungsten carbide ufa, zopangira za simenti carbide, monga momwe khofi ufa umakhudza mwachindunji kukoma kwa khofi. Ubwino wa tungsten carbide ufa umatsimikizira kwambiri momwe zinthu za carbide zimagwirira ntchito.

Kukula kwake kwa njere ya tungsten carbide ufa, kumapangitsa kulimba, kulimba komanso kuvala kukana kwa aloyi, kumalimbitsa mgwirizano pakati pa chomangira ndi tungsten carbide, komanso kukhazikika kwazinthuzo. Komabe, ngati kukula kwa tirigu ndi kochepa kwambiri, kulimba, kutentha kwa matenthedwe ndi mphamvu zamakina za zinthuzo zidzachepetsedwa, ndipo vuto lokonzekera lidzawonjezeka. "Kuwongolera molondola kwa zizindikiro zaumisiri ndi ndondomeko ya ndondomeko ndiye vuto lalikulu kwambiri. Popanga mankhwala a alloy apamwamba kwambiri, zofunikira za tungsten carbide powder zikukhala zovuta kwambiri.

Kwa nthawi yayitali, ufa wapamwamba wa tungsten carbide wakhala umadalira kwambiri kuchokera kunja. Mtengo wa ufa wamba wa tungsten carbide ufa womwe umagwiritsidwa ntchito podulira zida ndi 20% wokwera mtengo kuposa wa ku China, ndipo ufa wa nano tungsten carbide ufa ndi wokwera mtengo kuwirikiza kawiri. Komanso, makampani akunja amayankha pang'onopang'ono, sikuti amangofunika kusungitsatu pasadakhale, komanso amayenera kudikirira kwa miyezi ingapo kuti atumizidwe. Kufunika kwa msika wa zida kumasintha mofulumira kwambiri, ndipo nthawi zambiri maoda amabwera, koma kuperekedwa kwa zipangizo sikungathe kupitirira. Kodi ndiyenera kuchita chiyani ngati anthu ena akundilamulira? Chitani nokha!

Kumayambiriro kwa 2021, ku Zhuzhou, Hunan, msonkhano wanzeru wa ufa wa tungsten carbide ufa wokhala ndi ndalama zoposa 80 miliyoni za yuan unayamba ntchito yomanga, ndipo idzamalizidwa ndikuyika kumapeto kwa chaka.
Msonkhano wanzeru ndi waukulu komanso wowala. Pa coarse tungsten powder silo, nambala ya QR imalemba zidziwitso zakuthupi, ndipo chotengera chodziwikiratu chimawunikira kuwala kolowera, kutsekeka pakati pa ng'anjo yochepetsera ndi ng'anjo yamoto Panthawiyi, njira zopitilira 10 monga kudyetsa, kutsitsa ndi kusamutsa ndi pafupifupi opanda ntchito pamanja.

Kusintha kwanzeru kwasintha bwino komanso kuwongolera bwino, ndipo kafukufuku waukadaulo pakukonzekera sikunayime: njira ya tungsten carbide idapangidwira bwino kutentha kwa carburizing, ndipo mphero zapamwamba za mpira ndi ukadaulo wophwanya mpweya ndi njira zimagwiritsidwa ntchito kuonetsetsa kuti umphumphu wa kristalo ndi kubalalitsidwa kwa tungsten carbide ufa ali bwino kwambiri.

Kufuna kwapansi kumayendetsa kupita patsogolo kwaukadaulo wakumtunda, ndipo tungsten carbide ufa umakwezedwa mosalekeza mpaka pamlingo wapamwamba. Zida zabwino zimapanga zinthu zabwino. Ufa wapamwamba kwambiri wa tungsten carbide umabaya "majini" abwino muzinthu zokhala ndi simenti zotsika, zomwe zimapangitsa kuti zinthu ziziyenda bwino, ndipo zitha kugwiritsidwa ntchito m'magawo "olondola kwambiri" monga zakuthambo, zidziwitso zamagetsi, ndi zina zambiri.

Pafupi ndi mzere wopangira ufa wa tungsten carbide ufa, mzere wina wanzeru wopangira tungsten carbide ufa wokhala ndi ndalama zokwana 250 miliyoni wa yuan ukumangidwa. Zikuyembekezeka kumalizidwa ndikupangidwa chaka chamawa, pomwe mtundu wa ufa wa tungsten carbide ufa udzafika pamlingo wapamwamba wapadziko lonse lapansi.
