Kuwombera Kwachitsulo Chochepa Chozungulira Kaboni
Chitsanzo/Kukula:S110-S930/Φ0.3mm-2.8mm
Tsatanetsatane wa Zamalonda:
Kuwombera kwachitsulo chochepa cha carbon kumakhala ndi mpweya wochepa, phosphorous ndi sulfure kusiyana ndi kuwombera kwachitsulo cha carbon.Chifukwa chake, mawonekedwe amkati ang'onoang'ono owombera kaboni otsika amakhala osalala.Kuwombera kwachitsulo chochepa cha carbon ndikocheperako poyerekeza ndi kuwombera kwachitsulo cha carbon .Izi zimabweretsa 20 - 40% ya nthawi yayitali ya moyo wa abrasive.

Njira Zokonzekera:
Zakale→Sankhani&Kudula→Kusungunula→Yenerani(kuchotsa carbon)→Kutentha→Kuyanika→Kuunika →Kuthirira ndi Kuwomba kuti muchotse bowo la mpweya→Kuzimitsa koyamba→Kuyanika→Kutaya →Kutentha kwachiwiri→Kuziziritsa→Kusunga →Kuyika &Kusunga
Mapulogalamu:
Malo ogwiritsira ntchito: Kukonzekera koyambirira kwazitsulo kapena zitsulo zotayira musanayambe kujambula, kuchotsa ndi kuchotsa dzimbiri, kuchotsa.
Ubwino:
① Yoyenera kugwiritsidwa ntchito popereka zitsulo zoyera, zopukutidwa.
② Kuwombera kwachitsulo chochepa cha carbon kumagwiritsidwa ntchito mu makina onse a turbine ndi makina oponderezedwa.Kuwombera kwachitsulo chochepa cha carbon kumatsimikizira kuti masamba otsika a turbine amavala.
③Kuwombera kwachitsulo chochepa cha carbon kumakhala kotalika pafupifupi 30% kuposa kuwombera wamba kwachitsulo cha carbon.
④ Njira yophulitsira kuwombera imatulutsa fumbi lochepa, zomwe zimapangitsa kuti pakhale ndalama zochepetsera zosefera.
Chifukwa Chiyani Mpweya Wochepa?
Kuwombera kwachitsulo chochepa cha carbon ndi high manganese kumakhala ndi mphamvu yoyamwa kwambiri, zotsatira zake zimagawidwa mofanana panthawi yonseyi.
Panthawi yowombera kuwombera, chitsulo chochepa cha carbon chitsulo chimasenda pansi kukhala zigawo zopyapyala zofanana ndi anyezi kwa 80 peresenti ya moyo wawo chifukwa cha kuvala, ndipo amangosweka kukhala tiziduswa tating'ono chifukwa cha kutopa kwa zinthuzo.Kukokoloka kwa makina ndi tsamba kumachepetsedwanso kwambiri chifukwa amagawidwa m'magawo ang'onoang'ono komanso ang'onoang'ono.
Mkulu wa carbon zitsulo kuwombera particles komabe amasweka mu zidutswa zazikulu ndi zomangika mu nthawi yochepa chifukwa cha ming'alu dongosolo kupanga popanga.Ndi mbali iyi, makinawa amabweretsa ndalama zowonjezera pazida za turbine ndi zosefera.
