NM400 / NM 450 kuvala kukana zitsulo mbale
NM450 ndi mbale yovala mwamphamvu kwambiri.
Kutchula dzina: N ndi kukana (nai), M ndi chilembo choyamba cha pinyin cha zilembo ziwiri zaku China zopera (mo),
ndipo 450 imayimira pafupifupi kuuma kwa Brinell kwa mbale iyi yachitsulo
Chithandizo cha kutentha: kutentha kwakukulu, kuzimitsa + kutentha (kuzimitsa ndi kutentha)
Ntchito: NM450 kuvala zosagwira zitsulo mbale chimagwiritsidwa ntchito mu migodi makina, malasha migodi makina,
makina oteteza zachilengedwe, makina omanga, etc., ndipo amagwiritsidwanso ntchito ngati amphamvu kwambiri
zitsulo zomangamanga ndi mphamvu zokolola ≥850MPa.
Ntchito: Ndi makamaka kupereka chitetezo mu zochitika kapena mbali zofunika kuvala kukana, kuti moyo wa
zida ndizotalikirapo, kutsika kwanthawi yokonza komwe kumachitika chifukwa chokonza kumachepetsedwa, komanso ndalama zogulira ndalama
amachepetsedwa mofanana.
Magwiridwe: Zokolola zimaposa 950, ndipo mphamvu yokhazikika ndi 1180.
NM450 limafanana ndi mfundo zachilendo ndi makalasi JFE:NK-EH450/HARDOX450/DILLDUR:450V

Zithunzi zopanga:
Kupakira ndi Kuyika:
Kugwiritsa Ntchito Kwambiri:
1) Makina omanga ndi zida: chojambulira, bulldozer, chofufutira, mbale ya ndowa, mbale yam'mbali,
mbale pansi pa chidebe, tsamba, ndi mbale ya sill.
2) Kutsitsa ndikutsitsa makina ndi zida: kutsitsa mbale ya mphero, mbale yachitsulo, mbale yachitsulo,
mbale yapakatikati yotayira galimoto yotayirapo
3) Makina omanga ndi zida: mbale ya mano ya chopukusira simenti, chosakaniza chophatikizira konkriti, mbale yachitsulo
kusakaniza pansi, lining mbale ya fumbi wotolera
4) zitsulo makina ndi zipangizo: chitsulo ore sintering kubweretsa chigongono, chitsulo ore sintering makina akalowa,
scraper lining
5) Makina opangira migodi ndi zida: ore, chopondapo miyala, masamba.
6) Zida zina zamakina: mbiya ya mphero yamchenga, masamba, mbali zosagwira ntchito zamakina osiyanasiyana adoko.
7) Zida zamagetsi zamagetsi: malasha mphero akalowa mbale, malasha hopper, malasha kugawa chitoliro, malasha kugawa wogawa
grid, mbale ya malasha yotsitsa zida
