Cemented carbide ndi ufa zitsulo zopangidwa ndi carbide (WC, TiC) micron-level ufa wa high hardness refractory zitsulo monga chigawo chachikulu, ndi cobalt (Co) kapena faifi tambala (Ni), molybdenum (Mo) monga binder, chidwi ng'anjo ya vacuum kapena ng'anjo yochepetsera haidrojeni.
Magulu ndi Maphunziro
①Tungsten ndi Cobalt Cemented Carbide
Chigawo chachikulu ndi tungsten carbide (WC) ndi binder cobalt (Co).
Gululi limapangidwa ndi "YG" ("hard, cobalt" ku Hanyu Pinyin) ndi kuchuluka kwa cobalt pafupifupi.
Mwachitsanzo, YG8, amatanthauza pafupifupi WCo = 8%, ndipo ena onse ndi tungsten carbide carbide.
②Tungsten, titaniyamu ndi cobalt cemented carbide
Zigawo zazikuluzikulu ndi tungsten carbide, titanium carbide (TiC) ndi cobalt.
Gululi limapangidwa ndi "YT" ("hard, titaniyamu" ku Hanyu Pinyin) komanso kuchuluka kwa titanium carbide.
Mwachitsanzo, YT15, imatanthauza WTi = 15%, yotsalayo ndi tungsten carbide ndi cobalt zomwe zili mu tungsten titanium cobalt carbide.
③Tungsten-titanium-tantalum (niobium) mtundu wa carbide
Zigawo zazikuluzikulu ndi tungsten carbide, titanium carbide, tantalum carbide (kapena niobium carbide) ndi cobalt.Mtundu uwu wa carbide umatchedwanso carbide-purpose carbide kapena universal carbide.
Mayiko omwe akutulutsa kwambiri
Pali mayiko oposa 50 padziko lapansi kupanga simenti carbide, ndipo linanena bungwe okwana akhoza kufika 27,000-28,000t-, maiko waukulu kupanga ndi USA, Russia, Sweden, China, Germany, Japan, UK, France, etc. msika wa simenti wa carbide uli m'malo odzaza, ndipo mpikisano wamsika ndiwowopsa.Makampani opanga simenti ku China adapangidwa kumapeto kwa zaka za m'ma 1950, ndipo adakula mwachangu kuyambira m'ma 1960 mpaka m'ma 1970.Kumayambiriro kwa zaka za m'ma 1990, mphamvu yaku China yopangira simenti ya carbide inafika pa 6000t, ndipo kuchuluka kwa carbide yopangidwa ndi simenti kunafika 5000t, kuyika 3 padziko lonse lapansi pambuyo pa Russia ndi United States.
Ndodo za Carbide ndi zida zodulira za carbide, zomwe ndizoyenera magawo osiyanasiyana akupera movutikira, zida zodulira komanso zinthu zopanda zitsulo.Izo ntchito ochiritsira zodziwikiratu ndi theka-zodziwikiratu lathes, etc.
Choyamba, bar ya carbide ili ndi ntchito zosiyanasiyana pamakina.Itha kugwiritsidwa ntchito popanga zida zosinthira mwachangu, zida za mphero, mitu ya cobalt, zida zowongolera ndi zida zina zojambulira, zomwe zimatha kusintha liwiro lodulira.
Ikhoza kusintha liwiro la kudula ndi kuyendetsa bwino, kuchepetsa mtengo wopangira, komanso kuonetsetsa kuti zinthuzo zili zolondola komanso zapamwamba.
Kachiwiri, pankhani yokonza zinthu, ndodo za simenti za carbide zimakhalanso ndi ntchito zofunika.
Itha kupanga zitsulo zobowola mafuta, zobowola miyala, zodula ndi kufa zina, zomwe zimatha kukhalabe ndi magwiridwe antchito pansi pa malo ovuta kwambiri amphamvu kwambiri, kuuma kwakukulu komanso kuthamanga kwambiri, kuwongolera bwino magwiridwe antchito ndi mtundu.
Kuphatikiza apo, ndodo za simenti za carbide zimagwiranso ntchito yofunika kwambiri pantchito yamigodi.Itha kugwiritsidwa ntchito popanga zida zoboola migodi, zida zobowola malasha, zida zobowoleza geological ndi zida zina, zomwe zimatha kuchita mitundu yosiyanasiyana ya kubowola, kubowola, kuzindikira zolakwika ndi ntchito zina m'malo ovuta komanso am'mbali zambiri zamigodi, kuonetsetsa chitetezo. ndi kuzindikira kolondola kwa dera la migodi.
Nthawi zambiri, ndodo za carbide zokhala ndi kukana kwamphamvu kwambiri, kulimba kwamphamvu komanso kutentha kwakukulu zimagwiritsidwa ntchito kwambiri popanga makina, kukonza zinthu, migodi ndi madera ena, zomwe zimatha kupititsa patsogolo kulimba ndi magwiridwe antchito a zida, motero zimakwaniritsa bwino mafakitale, kupulumutsa mphamvu komanso chilengedwe. chitukuko cha chitetezo.
Mawonekedwe:
Amagwiritsidwa ntchito kwambiri pobowola PCB, mitundu yosiyanasiyana ya mphero, reamers, zobowoleza, etc.;
- Kugwiritsa ntchito ma ultra-fine specifikationer sub-micron, kuphatikiza koyenera kwa mavalidwe apamwamba kwambiri komanso kulimba kwamphamvu;
- Kukaniza ma deformation ndi kupatuka;
- China tungsten Online ili ndiukadaulo wapamwamba wopanga wa tungsten alloy round bar;
Momwe mungasinthire bar yozungulira ya carbide kukhala chida cha carbide?Ndi kusintha kosalekeza kwa mafakitale, zofunikira za carbide round bar zikuchulukiranso.M'makampani opanga makina olondola kwambiri, kutha kwa zida za carbide kumatha kuwononga kulondola kwazinthu, ndipo kuchuluka kwa zida zomwe zidatha kumachepetsedwa makamaka ndi index ya cylindrical ya mipiringidzo ya carbide.Popanga carbide bar, cylindrical ya bala yopanda kanthu imakhudzidwa ndi zinthu ndi zitsulo zamafuta, motero kuwongolera kwapang'onopang'ono kwa carbide kumakhala makamaka pakukonza kotsatira ndi chithandizo chapadera.Nthawi zambiri, njira yayikulu yopangira mipiringidzo ya carbide ndiyopera pakati.Njira yopukutira yapakati imakhala ndi magawo atatu: gudumu lopukuta, gudumu losinthira ndi chogwirira ntchito, pomwe gudumu lopukuta limagwira ntchito ngati akupera, gudumu lowongolera limayang'anira kuzungulira kwa ntchitoyo ndikupangitsa kuti ntchitoyo ichitike. pa mlingo wa chakudya, komanso chogwirira ntchito, chomwe chimathandizira ntchitoyo panthawi yopera, magawo atatuwa akhoza kukhala ndi njira zingapo zogwirira ntchito (kupatulapo kusiya kugaya), zonse zomwe zimakhala zofanana.
Cylindrical ndi kalozera wokwanira kuyeza kuzungulira ndi kuwongoka kwa kapamwamba.Cylindrical ya bar carbide imakhudzidwa makamaka ndi kutalika kwapakati pa ntchito yokonzedwa, kuchuluka kwa chakudya chamagulu, liwiro la chakudya, komanso kuthamanga kwa gudumu lowongolera pakatikati-pakatikati pogaya.Chifukwa chake gwirani cylindrical index kuti bar ya carbide "isinthe" kukhala chida chapamwamba kwambiri cha carbide.
