Mune yemazuva ano maindasitiri system, inopisa-yakakungurutswa simbi coils zvinhu zvekutanga, uye kusiyana kwavo kwemamodheru uye misiyano yekuita zvinokanganisa zvakananga mafambiro ekusimudzira maindasitiri epasi. Mhando dzakasiyana dzeanopisa-akakungurutswa simbi makoiri anoita basa risingadzokerike muminda yekuvaka, mota, simba, nezvimwe neayo akasiyana makemikari kuumbwa uye michina zvinhu. Izvi zvinotevera zvinotarisa pakuongorora iyo inopisa-yakakungurutswa simbi coil modhi ine yakanyanya kudiwa yemusika uye misiyano yavo yakakosha.
Basic Main Force: Q235B uye SS400
Q235B ndiyo inonyanya kushandiswa yakaderera-kabhoni structural simbi muChina, ine kabhoni inosvika 0.12% -0.20%, uye ine yakanaka yepurasitiki uye welding zvivakwa. Simba regoho rayo ≥235MPa uye rinoshandiswa zvakanyanya mukuvaka mafuremu, zvitsigiro zvebhiriji uye zvikamu zvemechanicha. Muindasitiri yekuvaka, maI-beam, machannel steels uye mamwe masimbi akagadzirwa neQ235B anopisa-akakungurutswa simbi coils account inodarika 60%, ichitsigira skeleton yezvivakwa zvemaguta.
SS400 isimbi inoshandiswa pasi rose kabhoni ine simba rakafanana neQ235B, asi yakanyatso kudzora tsvina yesarufa nephosphorus uye nani pamusoro pemhando. Mumunda wekuvaka ngarava, SS400 inopisa-yakatenderedzwa coils inowanzoshandiswa kune hull structural parts. Yayo yegungwa corrosion kuramba iri nani pane yakajairwa kabhoni simbi, kuve nechokwadi kuchengetedzwa kwenzendo dzemugungwa.
High-simba Representatives: Q345B uye Q960
Q345B isimbi yakadzika-alloy yakakwirira-simba ine 1.0% -1.6% manganese yakawedzerwa, uye simba regoho riri pamusoro pe345MPa. Kuenzaniswa neQ235B, simba rayo rinowedzera ne50%, uku ichichengetedza yakanaka weldability. Muinjiniya yemabhiriji, magidhi emabhokisi akagadzirwa neQ345B anopisa-akakungurutswa simbi coils anogona kuderedza huremu ne20%, zvakanyanya kuderedza mari yeinjiniya. Muna 2023, kuvakwa kwemabhiriji epamba kuchadya anopfuura mamirioni gumi nemaviri ematani eQ345B anopisa-akakungurutswa makoiri, achiverengera makumi mana neshanu muzana ezvese zvinobuda zverudzi urwu.
Semunhu akajairwa mumiriri weyakanyanya-yakanyanya simba simbi, Q960 inowana goho re ≥960MPa kuburikidza ne microalloying tekinoroji (kuwedzera vanadium, titanium uye zvimwe zvinhu) uye inodzorwa kukunguruka uye inodzora kutonhora maitiro. Mumunda wemichina yeinjiniya, ukobvu hweruoko rwecrane rwakagadzirwa neQ960 inopisa-yakatenderedzwa coil inogona kudzikiswa kusvika isingasviki 6mm, uye simba rekutakura mutoro rinowedzerwa nekatatu, izvo zvinokurudzira kukwidziridzwa kwakareruka kwemidziyo yakadai semachera uye cranes.
Special Benchmark: SPHC uye SAPH340
SPHC chigadzirwa chepamusoro-soro pakati pesimbi inopisa-yakaputirwa yakaderera-kabhoni. Nekugadzirisa maitiro ekukungurutsa kudzora saizi yezviyo, kureba kunosvika kupfuura 30%. Muindasitiri yemidziyo yemumba, maSPHC anopisa-akatenderedzwa makoiri anoshandiswa kugadzira firiji compressor dzimba. Kuita kwayo kwakadzama kudhirowa kunovimbisa kuti chiyero chakakodzera cheyakaomeswa yakakombama kuumba inodarika 98%. Muna 2024, kushandiswa kweSPHC inopisa-yakatenderedzwa makoiri mumunda wemidziyo yemumba ichawedzera ne15% gore-pa-gore kusvika 3.2 miriyoni matani.
Sesimbi yemotokari, SAPH340 inowana chiyero pakati pesimba nekuoma nekuwedzera 0.15% -0.25% kabhoni uye trace boron. Mukugadzira mafuremu ebhatiri remagetsi emagetsi matsva, SAPH340 inopisa-yakatenderedzwa coils inogona kushingirira mitoro inodarika 500MPa uye inosangana nezvinodiwa zveSpot welding process. Muna 2023, chikamu chemafuta anopisa-akatenderedzwa emhando iyi anoshandiswa mumotokari nyowani dzemagetsi asvika 70% yezvikamu zvebhatiri.
| Model | Goho Simba (MPa) | Elongation (%) | Mamiriro Ekushandisa Akajairika |
| Q235B | ≥235 | ≥26 | Zvivakwa zvekuvaka, general machine |
| Q345B | ≥345 | ≥21 | Mabhiriji, midziyo yekumanikidza |
| SPHC | ≥275 | ≥30 | Midziyo yemumba, auto parts |
| Q960 | ≥960 | ≥12 | Injiniya michina, yepamusoro-yekupedzisira michina |
Kana iwe uchida kuziva zvakawanda nezvesimbi, ndapota ramba uchiteerera kana kutibata nesu.
