Ukwakheka kwamakhemikhali: C2.05, SI1.40, MN 0.78, CR 26.03, NI0.81, MO0.35
Inqubo esetshenziswa kakhulu yokwelashwa okushisa kwensimbi ephezulu ye-chromium cast ukushisa ku-950 ~ 1000 degree, bese kuthi ngemuva kwezinga elingu-200 ~ 260℃lokushisa okushisa okuphansi.
Ukushisa okushisa kakhulu kwe-pelleting ukwelashwa 1140 ~ 1180℃ukufakwa komoya we-16h air ukuphola, kungathuthukisa kakhulu ubulukhuni bethonya nokugqoka. Ukwelashwa okuphezulu okuphezulu okushisa kungenza wonke ama-carbides frival, angakuqeda noma anciphise ukwahlukana kwesisindo esikhulu kanye ne-carbide yenethiwekhi eqhubekayo kwi-matrix, i-carbide eyindilinga isekelwa yi-matrix efanayo ye-aucen. Uma isikhathi sokufakwa sincishiswe ngokufanele, izingxenye ezicinene nezingxenye zingasebenza. Ukushoda kwale nqubo ukuthi inqubo idla amandla okushisa amaningi.
Ukushisa kuya ku-1050 degree, bese wenza ama-550℃varian, kuzoba kanjani umphumela?
Ukulawula ijubane lokushisa, kungcono ukuqhubeka ufudumele isikhathi esithile ngamahora angama-650. Ngikwenzile ngaphambili, ngomlilo nje. Ubulukhuni bungafinyelela 61- - - -65 HRC
Inqubo evuthiwe yile: Ukusetshenziswa kobulukhuni ngokuvamile kuyadingeka ku-HRC 58-62, ikakhulukazi okusetshenziselwa njengezingxenye zamaphampu we-slurry nokunye ukugqoka nokugqoka izingxenye.
Siyisizinda esiphakeme se-Chromium, ngokuvamile sinikezela ngo-CR 24, CR 26, cr 28, CR15MO3, njll. Manje sisebenzisa ukucima ama-liquid aqedelayo aqedekayo, ama-parameter enqubo aqothulayo Izinga lokushisa elinonduku 380 ~ 400,4 ~ 6 amahora okufakelwa. Ukugaya Ibhola elicacisiwe Φ 40 Φ 8.
Inqubo ingu-1050 aqedeka + 250 ~ 350 Feating
