Kupisa-yakakungurutswa forged Steel bar isimbi inogadzirwa neinopisa-inotenderedza maitiro, ayo anowanzo ane yakakwirira michina zvivakwa uye yakafara minda yekushandisa. Izvi zvinotevera ongororo yakadzama yehot rolled forged rods:

Kupisa kutenderedza maitiro: Kupisa kutenderedza kunoitwa nekugadzirisa zvishoma nezvishoma simbi billet pasi pemamiriro ekushisa akanyanya kuburikidza nenhevedzano yekutenderedza maitiro (sekuenderera mberi kwekukanda isina chinhu → rough rolling → yepakati kutenderedza → kupedzisa kukunguruka, nezvimwewo).

Mukuita uku, simbi billet inopisa kusvika pakupisa kwepamusoro uye yobva yakungurutswa kakawanda kuburikidza neguyo rekukungurutsira kuti pakupedzisira iite inodiwa bar shape uye saizi. Iyi nzira inogona kuvandudza zvakanyanya chimiro chemukati uye zvimiro zvechinyorwa, ichichipa zviri nani ma mechanical properties uye kugadzirisa zvinhu.

Hot rolledsimbi dzakagadzirwa nesimbianoshandiswa zvakanyanya munzvimbo dzakasiyana siyana, kusanganisira asi kwete kugumira ku:

Mechanical midziyo: inoshandiswa kugadzira zvikamu uye zvikamu zveakasiyana mishini michina, senge mabheya, magiya, shafts, nezvimwe.
Indasitiri yemotokari: inoshandiswa kugadzira masisitimu ekufambisa, masisitimu ekumisa, zvikamu zveinjini, nezvimwe zvemotokari.
Injiniya yekuvaka: inoshandiswa kugadzira simbi yekuvaka, senge mbiru dzesimbi, matanda esimbi, simbi mbariro, nezvimwe.
Aerospace: Nekuda kwesimba rayo repamusoro uye kusimba kwepamusoro, inopisa-yakakungurutswa yakagadzirwasimbi mbariroanoshandiswawo zvakanyanya mundima yeaerospace, sekugadzira mashizha einjini yendege, giya rekumhara uye zvimwe zvakakosha.

Musi waGunyana 3, 2024, Chilean Anti-Price Distortion Commission (CNDP) yakazivisa danho rayo rekumisa kuferefetwa kweAnti-Dumping (AD) pakuferefeta.simbi mbariroyekugadzira mabhora ekukuya ane dhayamita isingasviki 4 inches anobva kuChina, achikurudzira kusamanikidza mabasa eAD.

Nekuda kweizvozvo, basa renguva pfupi reAD pamasimbi esimbi nemabhora, pamwe nechiyero chebasa che33.5% uye 24.9% chakaiswa muna Kubvumbi, chichapera.

Chigadzirwa chinobatanidzwa chakaiswa pasi peHS kodhi 7228.3000.
