Ndodo Yozungulira ya Chitsulo cha Kaboni ya 1018, Yosapukutidwa (Mill), Yozizira Yomalizidwa, ASTM A108, 1.25″ Diameter, 24″ Kutalika

Chitsulo chozungulira chimatanthauza chitsulo cholimba chachitali chokhala ndi gawo lozungulira. Mafotokozedwe ake amafotokozedwa m'mimba mwake, mu mamilimita (mm). Mwachitsanzo, "50mm" amatanthauza chitsulo chozungulira chokhala ndi m'mimba mwake wa 50mm. Kugawa m'magulu malinga ndi kapangidwe ka mankhwala Chitsulo cha kaboni chingagawidwe m'magulu awiri: chitsulo chopanda mpweya, chitsulo chapakati cha kaboni ndi chitsulo chopanda mpweya wambiri malinga ndi kapangidwe ka mankhwala (monga kuchuluka kwa kaboni).

1.Chitsulo chotsika cha mpweya

Chimadziwikanso kuti chitsulo chofatsa, chitsulo chopanda mpweya wokhala ndi mpweya wochepa kuyambira 0.10% mpaka 0.30% n'chosavuta kulandira njira zosiyanasiyana zochizira, monga kupangira, kuwotcherera ndi kudula. Chimagwiritsidwa ntchito kwambiri popanga unyolo, ma rivets, mabolts, shafts, ndi zina zotero.

2. Chitsulo chapakati cha mpweya

Chitsulo cha kaboni chokhala ndi mpweya wa 0.25% ~ 0.60%. Palinso chitsulo chophedwa, chitsulo chophedwa pang'ono, chitsulo chowira ndi zinthu zina. Kuwonjezera pa kaboni, chingakhalenso ndi manganese pang'ono (0.70% ~ 1.20%). Malinga ndi khalidwe la chinthucho, chimagawidwa m'zitsulo wamba wa kaboni ndi chitsulo chapamwamba cha kaboni. Kugwira ntchito bwino kotentha ndi kudula, kusagwira bwino ntchito kwa welding. Mphamvu ndi kuuma kwake ndi kwakukulu kuposa kwa chitsulo chofooka cha kaboni, pomwe pulasitiki ndi kulimba kwake ndizochepa kuposa kwa chitsulo chofooka cha kaboni. Zipangizo zokulungidwa ndi zozizira zotenthedwa ndi zotenthedwa zimatha kugwiritsidwa ntchito mwachindunji popanda kutentha, ndipo zingagwiritsidwenso ntchito mutatentha. Chitsulo chapakati cha kaboni ndi chomwe chimagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana ndi mphamvu yapakati. Kuwonjezera pa kugwiritsidwa ntchito ngati zipangizo zomangira, chimagwiritsidwanso ntchito kwambiri popanga zida zosiyanasiyana zamakanika.

3. Chitsulo cha kaboni chokwera kwambiri

Kawirikawiri imatchedwa chitsulo cha zida, chokhala ndi mpweya wochuluka kuyambira 0.60% mpaka 1.70%, chomwe chimatha kuumitsidwa ndi kutenthedwa. Hammer ndi crowbar zimapangidwa ndi chitsulo chokhala ndi mpweya wochuluka wa 0.75%; zida zodulira monga drill bit, tap ndi reamer zimapangidwa ndi chitsulo chokhala ndi mpweya wochuluka wa 0.90% mpaka 1.00%.
