Chitsulo chomanga chimapangidwa makamaka ku zinthu zachitsulo. Ambiri mwa zomangamanga ku China amapangidwa kuchokera ku chitsulo chochepa, chapakati-carbon chitsulo ndi chitsulo chotsika ndi chitsulo chophika kapena kuphera seel. Pakati pawo, zitsulo zophedwa zimalimbikitsidwa ku China. gwiritsani ntchito.
Mitundu yomanga yachitsulo imagawika m'magulu angapo monga kubwezeretsa, kuzungulira kwachitsulo, ndodo yaya, col screw.
1. Kubweza
Kutalika kwakukulu kwa rebar ndi 9m ndi 12m. Ulusi wautali wa 9m umagwiritsidwa ntchito pomanga msewu, ndipo ulusi wautali wa 12m umagwiritsidwa ntchito makamaka pomanga mlatho. Kutanthauzira kwa ulusi kwa ulusi nthawi zambiri, ndipo dzikolo limalola kupatuka. Pali mitundu itatu yobwezeretsedwa malinga ndi mphamvu: HRB335, HRB400 ndi HRB500.
2. Chitsulo chozungulira
Monga momwe dzinalo limanenera, zitsulo zozungulira ndi mtunda wautali wautali gawo lozungulira, lomwe limagawidwa m'mitundu itatu: yotentha, yopangidwa komanso yozizira. Pali zinthu zambiri zozungulira, monga: 10 #, 20, 45 #, 42crMo, 30crn, 20crn, 20cr, 20crdo, etc.
Kukula kwa chitsulo chozizira chozungulira ndi 5.5-250 mm, ndipo kukula kwa 5.5-25 mm ndi chitsulo chaching'ono, chomwe chimaperekedwa m'mitolo yolunjika ndikugwiritsa ntchito ngati chitsulo, ma balts ndi magawo osiyanasiyana; Chitsulo chozungulira chochulukirapo kuposa 25 mm chimagwiritsidwa ntchito popanga zigawo zamakina kapena ma billets achitsulo osawoneka bwino.
3. waya
Mitundu yodziwika bwino ya magetsi ndi Q195, Q215, ndi Q235, koma pali mitundu iwiri yokha ya maya aya womanga, Q215 ndi Q235. Nthawi zambiri, zokambirana zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala 6.5mm mulifupi, 8.0mm m'mimba mwake, ndi 10mm mu mainchesi. Pakadali pano, ndodo yayikulu kwambiri m'dziko langa imatha kufikiranso 30mm. Kuphatikiza pa kugwiritsidwa ntchito ngati zolimbikitsa pakumanga konkriti zolimbitsa thupi, waya amathanso kugwiritsidwa ntchito pojambula wa waya ndi mauna.
4. Nkhovu
Chotupa cholumikizidwa ndi mtundu wa zitsulo zomwe zimagwiritsidwa ntchito pomanga. Kubwezedwanso kumagwiritsidwa ntchito kwambiri m'mitundu yosiyanasiyana yomanga. Ubwino wa zomangira zophatikizika poyerekeza ndi zotungiraziro ndi: zotchingira zili 9-12, ndipo zomata zozikidwazo zitha kukhala zosasunthika molingana ndi zosowa zogwiritsira ntchito.
