Zida Zodulira Carbide Simenti

Tungsten carbide ndi gulu lomwe limagwiritsidwa ntchito kwambiri pazida zopangira makina othamanga kwambiri (HSM), zida zotere zimapangidwa ndi njira yazitsulo ya ufa, yomwe imakhala ndi tinthu tating'onoting'ono ta carbide (kawirikawiri tungsten carbide WC) ndi kulumikizana kwazitsulo zofewa. Pakali pano, pali mazana a zigawo zosiyanasiyana za WC-based simenti carbide, ambiri a iwo amagwiritsa cobalt (Co) monga chomangira, faifi tambala (Ni) ndi chromium (Cr) amagwiritsidwanso ntchito zomangira zinthu, kuwonjezera pa aloyi zina. zinthu zikhoza kuwonjezeredwa. Chifukwa chiyani pali magiredi ambiri a simenti a carbide? Kodi wopanga zida zodulira amasankha bwanji chida choyenera panjira inayake yodulira? Kuti tiyankhe mafunsowa, tiyeni tione kaye zinthu zosiyanasiyana zomwe zimapanga simenti ya carbide kukhala chida choyenera chodulira.

Kuuma ndi kulimba:WC-Co carbide ili ndi maubwino apadera pakuuma komanso kulimba. Tungsten carbide (WC) palokha imakhala ndi kuuma kwakukulu (kuposa corundum kapena alumina), ndipo kuuma kwake sikucheperachepera pamene kutentha kwa ntchito kumakwera. Komabe, ilibe kulimba kokwanira, komwe kuli kofunikira pazida zodulira. Pofuna kupezerapo mwayi pa kuuma kwakukulu kwa tungsten carbide ndikuwongolera kulimba kwake, anthu amagwiritsa ntchito zitsulo zomangira zitsulo kuti agwirizanitse tungsten carbide pamodzi, kotero kuti zinthuzi zimakhala zolimba kwambiri kuposa zitsulo zothamanga kwambiri, ndipo nthawi yomweyo zimatha. kupirira mphamvu yodula mu njira zambiri zodula. Kuphatikiza apo, imatha kupirira kutentha kwambiri komwe kumapangidwa ndi makina othamanga kwambiri.

Masiku ano, pafupifupi zida zonse za WC-Co ndi masamba amakutidwa, kotero kuti gawo la zinthu zoyambira likuwoneka ngati losafunikira. Koma kwenikweni, ndizomwe zimakhala zotanuka kwambiri za WC-Co (muyeso wa kuuma, kutentha kwa chipinda cha WC-Co ndi pafupifupi kuwirikiza katatu kuposa chitsulo chothamanga kwambiri) chomwe chimapereka zokutira kuti zisawonongeke. maziko. Matrix a WC-Co amaperekanso kulimba kofunikira. Izi ndizomwe zimafunikira pazida za WC-Co, komanso ndizotheka kusintha zinthuzo posintha kapangidwe kazinthu ndi kamangidwe kakang'ono popanga ufa wothira simenti wa carbide. Chifukwa chake, kukwanira kwa zida zogwirira ntchito inayake kumadalira kwambiri pamayendedwe oyambira.

Pomaliza, chidziwitso chofunikira cha chida chilichonse chodulira ndi momwe chimagwirira ntchito ndikofunikira posankha zolondola. Zomwe zikuyenera kuganiziridwa zikuphatikizapo chinthu chomwe chiyenera kupangidwa, mtundu wa chinthu ndi mawonekedwe, makina opangira makina ndi mlingo wapamwamba wofunikira pa ntchito iliyonse. Mwachiwonekere, simenti ndi chisankho chabwino chopangira zida zodulira, ZZBETTER Carbide Tools Company ili ndi zaka zopitilira khumi popanga pafupifupi mitundu yonse ya zida za tungsten carbide.

Takulandirani kuti mutitumizireni ngati muli ndi funso kapena zofunikira pa zida za simenti za carbide, timathanso kuchita zinthu zopanda malire pokhapokha mutapereka zojambula zanu.
