Bambanci Tsakanin Cemented Carbide da High Speed ​​Steel (HSS)

Cemented carbide da high-gudun karfe ne hankula downstream kayayyakin na refractory karfe tungsten (W), duka biyu da kyau thermodynamic Properties, kuma za a iya amfani da su yi yankan kayan aikin, sanyi-aiki kyawon tsayuwa da zafi-aiki kyawon tsayuwa, da dai sauransu Duk da haka, saboda saboda da daban-daban kayan abun da ke ciki na biyu, sun kuma bambanta dangane da inji Properties da amfani.

1. Ra'ayi
Cemented carbide wani alloy abu ne wanda ya ƙunshi ƙarfe na ƙarfe na ƙarfe kamar tungsten carbide (WC) foda da ƙarfe mai haɗawa irin su cobalt foda. Sunan Ingilishi Tungsten Carbide / Cemented Carbide. Its high-zazzabi carbide abun ciki ne mafi girma fiye da na high-gudun karfe tsawo na.

Karfe mai sauri shine babban ƙarfe mai ƙarfi mai ƙarfi wanda ya ƙunshi babban adadin tungsten, molybdenum, chromium, cobalt, vanadium da sauran abubuwa waɗanda akasari sun haɗa da carbides na ƙarfe (kamar tungsten carbide, molybdenum carbide ko vanadium carbide) da karfe matrix, tare da carbon abun ciki na 0.7% -1.65%, jimlar adadin alloying abubuwa ne. 10% -25%, kuma sunan Ingilishi shine High Speed ​​Steels (HSS).

2. Aiki
Dukansu suna da halaye na tsayin daka, ƙarfin ƙarfi, mai kyau tauri, ja tauri, juriya juriya, juriya na zafi da aikin aiwatarwa, kuma waɗannan halayen zasu bambanta saboda nau'ikan daban-daban. Gabaɗaya magana, taurin, taurin ja, juriya da juriya na zafi na siminti carbide sun fi na ƙarfe mai saurin gudu.

3. Fasahar samarwa
Tsarin samar da siminti carbide ya haɗa da tsarin ƙarfe na foda, fasahar gyare-gyaren allura ko tsarin bugu na 3D.

Hanyoyin samar da ƙarfe mai sauri sun haɗa da fasahar simintin gargajiya, fasahar remelting electroslag, fasahar ƙarfe na foda da fasahar yin allura.

4. Amfani
Ko da yake duka biyu na iya yin wukake, kayan aiki masu zafi da kayan aikin sanyi, aikin su ya bambanta. Gudun yankan kayan aikin carbide na yau da kullun shine sau 4-7 sama da na kayan aikin ƙarfe na yau da kullun, kuma rayuwar sabis ɗin shine sau 5-80 ya fi tsayi. Dangane da gyare-gyare, rayuwar sabis na ciminti carbide ya mutu sau 20 zuwa 150 sama da na ƙarfe mai sauri ya mutu. Misali, rayuwar sabis na extrusion mai zafi ya mutu da karfe 3Cr2W8V shine sau 5,000. Yin amfani da extrusion mai zafi ya mutu da YG20 cemented carbide Rayuwar sabis shine sau 150,000.
