Tungsten Carbide VS HSS (2)

Kusiyana kwa zinthu zosakaniza

Tungsten carbide

The carbide simenti ali chigawo chachikulu cha chitsulo mkulu kuuma refractory carbide ndi WC ufa, cobalt (CO) kapena faifi tambala (Ni), ndi molybdenum (MO) monga binder. Ndi mankhwala opangidwa ndi zitsulo zopangidwa ndi zitsulo zosungunulidwa mu ng'anjo yowonongeka kapena ng'anjo yochepetsera haidrojeni.

HSS

Chitsulo chothamanga kwambiri ndi chitsulo chovuta, chokhala ndi mpweya nthawi zambiri pakati pa 0.70% ndi 1.65%, 18.91% Tungsten, 5.47% Chloroprene mphira, ndi 0.11% Manganese.

Kusiyanasiyana kwa njira zopangira

Tungsten carbide

Kupanga kwa simenti ya carbide ndikusakaniza tungsten carbide ndi cobalt mu gawo linalake, kuwakakamiza mu mawonekedwe osiyanasiyana, kenako semi-sintering. Izi sintering ndondomeko zambiri ikuchitika mu ng'anjo vacuum. Imayikidwa mu uvuni wa vacuum kuti amalize kuyatsa, ndipo panthawiyi, kutentha kumakhala pafupifupi 1300 ° C ndi 1,500 ° C. Chopangidwa ndi sintered tungsten carbide chapondereza ufawo kuti ukhale wopanda kanthu kenako ndikutenthedwa mpaka kumlingo wina mu ng'anjo yotentha. Imafunika kusunga kutentha kwa nthawi ndithu kenako kuziziritsa, potero kupeza zofunika carbide chuma.

HSS

Njira yochizira kutentha kwa HSS ndizovuta kwambiri kuposa carbide ya simenti, yomwe iyenera kuzimitsidwa ndi kupsya mtima. Kuzimitsa, chifukwa cha kusayenda bwino kwa matenthedwe, nthawi zambiri kumagawidwa m'magawo awiri. Preheat poyamba pa 800 ~ 850 °C, kotero kuti chifukwa chachikulu matenthedwe nkhawa, ndiye mwamsanga kutentha kwa quenching kutentha 1190 ° C kuti 1290 °C amene amasiyanitsidwa pamene magiredi osiyana mu ntchito yeniyeni. Kenaka muziziziritsa ndi kuziziritsa mafuta, kuziziritsa mpweya, kapena kuzizira modzaza ndi gasi.

Kugwiritsa ntchito zida za Tungsten carbide ndi zida za HSS

Tungsten carbide

Tungsten carbide itha kugwiritsidwanso ntchito ngati zida zobowola mwala, zida zamigodi, zida zoboola, zida zoyezera, zida zobvala za carbide, zomangira ma silinda, mayendedwe olondola, ma nozzles, nkhungu zamtundu monga kujambula waya kufa, bawuti kufa, mtedza umafa, ndi zomangira zosiyanasiyana. amafa, omwe ali ndi ntchito yabwino kwambiri, pang'onopang'ono m'malo mwa nkhungu yachitsulo yapitayi.

HSS

HSS imakhala ndi ntchito yabwino yophatikiza mphamvu ndi kulimba, chifukwa chake imagwiritsidwa ntchito kwambiri popanga zida zodulira zitsulo zokhala ndi m'mbali zoonda kwambiri komanso zosagwira bwino, zokhala ndi kutentha kwambiri komanso zisankho zoziziritsa kukhosi.

Chidule

Chida cha tungsten carbide chidzakhala chisankho chabwino kwambiri pakukonza zitsulo zambiri. Carbide yopangidwa ndi simenti imagwira ntchito bwino kuposa HSS, yokhala ndi liwiro lalitali kwambiri, moyo wautali wautumiki, komanso kukana kwamphamvu kwambiri. Chitsulo chothamanga kwambiri chimakhala choyenera kwambiri pazida zokhala ndi mawonekedwe ovuta.
