Chitoliro chachitsulo chowala chomalizidwa ndi chinthu chopangidwa ndi chitsulo cholondola kwambiri chikatha kujambula kapena kuzizira. Chifukwa makoma amkati ndi akunja a machubu owala olondola alibe oxide layer, palibe kutayikira pansi pa kupanikizika kwakukulu, molondola kwambiri, kumaliza kwambiri, palibe kusintha panthawi yozizira yopindika, kuphulika, kuphwanyika komanso palibe ming'alu, ndi zina zotero, amagwiritsidwa ntchito makamaka popanga zinthu zopangidwa ndi pneumatic kapena hydraulic components, monga ma cylinders kapena ma cylinders amafuta, omwe amatha kukhala machubu osalumikizana kapena machubu olumikizidwa. Kapangidwe ka mankhwala ka chubu chowala cholondola kumaphatikizapo carbon C, silicon Si, manganese Mn, sulfure S, phosphorous P, ndi chromium Cr.
Zinthu zazikulu za kumaliza chubu chowala:
Makoma amkati ndi akunja a chitoliro chachitsulo ali ndi kulondola kwakukulu komanso kutha kwapamwamba. Pambuyo potenthetsera, chitoliro chachitsulo chilibe oxide wosanjikiza, ndipo khoma lamkati lili ndi ukhondo wapamwamba. Chitoliro chachitsulo chili ndi mphamvu yamphamvu, kupindika kozizira sikuwonongeka, ndipo kuphulika ndi kuphwanyika sikusweka. Chitoliro chachitsulo chomalizidwa choperekedwa ndi Tianjin Century Zoomlion chingagwiritsidwe ntchito pokonza zinthu zosiyanasiyana zovuta komanso makina. Mtundu wa chitoliro chachitsulo: choyera ndi kuwala, chokhala ndi kunyezimira kwachitsulo kwambiri.
Mulingo wamba, zinthu ndi momwe katundu amaperekedwera-machubu owala opindidwa
Miyezo yayikulu: GB/T3639, DIN2391-94/C, DIN2445, EN10305, DIN1630, DIN1629, ASTMA106, ASTMA179, JISG3445
Zipangizo zazikulu: 10 #, 20 #, 35,45,40Cr, 25Mn.37Mn5, St35 (E235), St37.4, St45 (E255), St52 (E355)
Mkhalidwe waukulu wotumizira: NBK (+N), GBK (+A), BK (+C), BKW (+LC), BKS (+SR)
Kugwiritsa ntchitokumaliza-machubu owala opindidwa
Magalimoto, zowonjezera makina ndi makina ena omwe ali ndi zofunikira kwambiri pa kulondola ndi kusalala kwa mapaipi achitsulo. Tsopano ogwiritsa ntchito mapaipi achitsulo omalizidwa si okhawo omwe ali ndi zofunikira kwambiri pa kulondola ndi kumalizidwa. Chifukwa chakuti kulondola kwa mapaipi owala omalizidwa ndi okwera kwambiri ndipo kulekerera kumatha kusungidwa pa mawaya 2-8, ogwiritsa ntchito ambiri opanga makina akusintha pang'onopang'ono mapaipi achitsulo osasokonekera kapena chitsulo chozungulira kukhala mapaipi owala omalizidwa kuti apulumutse ntchito, zinthu ndi nthawi.
