Q345B gobvu madziro mativi pombi yemhando vimbiso
Huru dhayamita gobvu madziro sikweya pombi imhando yechiedza gobvu madziro simbi pombi ine hollow square chikamu, inozivikanwawo sesimbi inotonhora-yakaumbwa chimiro. Icho chikamu chesimbi chine sikweya chikamu chimiro uye saizi, iyo inogadzirwa neQ235 inopisa-yakatenderedzwa kana kutonhora-yakatenderedzwa tambo kana coil seyakadzika zvinhu, kutonhora kubhenda uye yakakwirira-frequency welding.
Zvinoenderana nemaitiro ekugadzira, hombe-dhayamita gobvu madziro sikweya pombi yakakamurwa kuva inopisa-yakakungurutswa gobvu madziro mativi pombi, inotonhora inoswededzwa gobvu madziro sikweya pombi, extruded gobvu rusvingo sikweya pombi uye welded sikweya pombi.
(a) Zvinoenderana nemaitiro - arc welding square chubhu, kuramba welding square chubhu (yakakwira frequency uye yakaderera frequency), gasi welding square chubhu uye choto welding square chubhu.
(b) Yakakamurwa ne weld - straight welded square pombi uye spiral welded square pombi
Huru dhayamita gobvu madziro sikweya pombi yakakamurwa kuita yakajairwa kabhoni simbi sikweya pombi uye yakaderera alloy square pombi zvinoenderana nezvinhu. Ordinary kabhoni simbi yakakamurwa: Q195, Q215, Q235, SS400, 20 # simbi, 45 # simbi, etc; Low alloy simbi dzakakamurwa kuita Q345, 16Mn, Q390, St52-3, nezvimwe.
Square simbi pombi, gobvu madziro square simbi pombi, hombe dhayamita square simbi pombi, musono sikweya simbi pombi, yakaderera alloy square simbi pombi, 135 * 135 * 10 square simbi pombi, sikweya simbi pombi yeshongwe crane, Q345B yakaderera alloy square simbi pombi, 20 # isina musono sikweya simbi nyere
Square chubhu, sekureva kunoita zita, imhando yeskweya chubhu. Zvishandiso zvakawanda zvinogona kuita square tube. Inoshandiswa kune, zvekuita uye kupi kushandisa. Machubhu mazhinji eskweya machubhu esimbi, anonyanya kuumbwa masikweyachubhu, ekushongedza sikweya machubhu, ekuvaka sikweya machubhu, nezvimwe.
Square pombi izita reskweya pombi, kureva, nyere yesimbi ine yakaenzana side kureba. Iyo inogadzirwa neyakakungurutswa strip simbi mushure mekuita kurapwa. Kazhinji, simbi yeshinda inosunungurwa, yakasimudzwa, yakashongedzwa uye yakasungirirwa kuti iite pombi yakatenderera, yobva yakungurutswa kuita pombi yakaenzana, yozocheka muhurefu hunodiwa. Kazhinji 50 zvidimbu pasuru.
Square machubhu anogona kukamurwa kuita seamless uye welded. Seamless sikweya machubhu anoburitswa kubva kune isina musono denderedzwa machubhu. Square simbi pombi, gobvu madziro square simbi pombi, hombe dhayamita square simbi pombi, musono square simbi pombi, yakaderera alloy square simbi pombi, 135 * 135 * 10 square simbi pombi, sikweya simbi pombi yeshongwe crane, Q345B yakaderera alloy square simbi pombi, 20 # isina musono sikweya simbi nyere
1. Performance index analysis ye square tube - plasticity
Plasticity inoreva kugona kwesimbi zvinhu kugadzira plastiki deformation (permanent deformation) pasina kukuvara pasi pemutoro.
2. Performance index analysis of square tube - kuoma
Kuomarara i chinongedzo chekuyera kuoma nekupfava kwezvinhu zvesimbi. Parizvino, nzira inonyanya kushandiswa yekuyera kuomarara mukugadzira ndiyo indentation kuomarara nzira. Inoshandisa indenter ine imwe geometry kudzvanya mukati meiyo yakaedzwa simbi zvinhu pasi pemumwe mutoro, uye inotarisisa kukosha kwayo kwekuomarara zvinoenderana nedhigirii remukati.
Nzira dzinowanzo shandiswa dzinosanganisira Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) uye Vickers kuoma (HV).
3. Performance index analysis ye square tube - kuneta
Simba, plasticity uye kuoma kwakakurukurwa pamusoro zvose zviratidzo zvemakanika zvinhu zvesimbi pasi pe static load. Muchokwadi, akawanda muchina zvikamu zvinoshanda pasi pe cyclic mutoro, pasi pekuti kuneta kuchaitika.
4. Performance index ongororo yesquare chubhu - kukanganisa kuoma
Kuremerwa kunoshanda pachikamu nekumhanya kukuru kunodaidzwa kuti impact load, uye kugona kwesimbi kuramba kutadza pasi pesimba remutoro kunonzi kukanganisa kuoma.
5. Performance index ongororo yesquare pombi - simba square simbi pombi, gobvu madziro square simbi pombi, hombe dhayamita square simbi pombi, isina musono square simbi pombi, yakaderera alloy square simbi pombi, 135 * 135 * 10 square simbi pombi, sikweya simbi pombi yeshongwe crane. , Q345B yakaderera chiwanikwa mativi simbi pombi, 20# musono mativi simbi pombi
Simba rinoreva kuramba kwesimbi zvinhu kukundikana (yakawandisa epurasitiki deformation kana kutyoka) pasi static mutoro. Sezvo maitiro ekuita ekuremerwa achisanganisira tension, kudzvanya, kukotama uye kugera, simba racho rakakamurwa kuita simba rekusimba, simba rekumanikidza, kuchinjika simba uye kugera simba. Panowanzova nekubatana kwakati pakati pesimba rakasiyana-siyana. Kazhinji, simba rekusimba rinoshandiswa seyakanyanya kukosha chiratidzo chesimba.
