Q345B wandiweyani khoma lalikulu chitoliro chitsimikizo khalidwe
Large m'mimba mwake wandiweyani mipanda lalikulu chitoliro ndi mtundu wa kuwala wandiweyani mipanda zitsulo chitoliro ndi dzenje lalikulu gawo, amatchedwanso zitsulo ozizira-opangidwa mbiri. Ndi chitsulo chachigawo chokhala ndi mawonekedwe apakati ndi kukula kwake, chomwe chimapangidwa ndi chingwe cha Q235 chotentha kapena chozizira kapena coil ngati maziko, kupindika kozizira komanso kuwotcherera kwanthawi yayitali.
Malinga ndi ndondomeko yopanga, lalikulu-m'mimba mwake wandiweyani khoma chitoliro lalikulu lagawidwa otentha-anagulung'undisa wandiweyani khoma lalikulu chitoliro, ozizira kukokedwa wandiweyani khoma lalikulu chitoliro, extruded wandiweyani khoma lalikulu chitoliro ndi welded lalikulu chitoliro.
(a) Malinga ndi ndondomeko - arc kuwotcherera lalikulu chubu, kukana kuwotcherera lalikulu chubu (mkulu pafupipafupi ndi otsika pafupipafupi), mpweya kuwotcherera lalikulu chubu ndi ng'anjo kuwotcherera lalikulu chubu
(b) Ogawanika ndi weld - wowongoka welded lalikulu chitoliro ndi spiral welded lalikulu chitoliro
Large m'mimba mwake wandiweyani khoma chitoliro lalikulu lagawidwa wamba mpweya zitsulo lalikulu chitoliro ndi otsika aloyi lalikulu chitoliro malinga ndi zinthu. Wamba mpweya zitsulo lagawidwa: Q195, Q215, Q235, SS400, 20 # zitsulo, 45 # zitsulo, etc; Zitsulo zotsika za aloyi zimagawidwa mu Q345, 16Mn, Q390, St52-3, ndi zina.
Square zitsulo chitoliro, wandiweyani khoma lalikulu zitsulo chitoliro, lalikulu m'mimba mwake lalikulu zitsulo chitoliro, opanda aloyi lalikulu zitsulo chitoliro, otsika aloyi lalikulu zitsulo chitoliro, 135 * 135 * 10 lalikulu zitsulo chitoliro, lalikulu zitsulo chitoliro kwa nsanja crane, Q345B otsika aloyi lalikulu zitsulo chitoliro, 20 # wopanda msoko lalikulu zitsulo chitoliro
Square chubu, monga dzina likunenera, ndi mtundu wa square chubu. Zida zambiri zimatha kupanga masikweya chubu. Amagwiritsidwa ntchito, zoyenera kuchita komanso komwe angagwiritsire ntchito. Machubu ambiri a square ndi machubu achitsulo, makamaka machubu a square, zokongoletsera masikweya machubu, machubu omangira masikweya, etc.
Square chitoliro ndi dzina lalikulu chitoliro, ndiko kuti, chitsulo chitoliro ndi ofanana mbali kutalika. Amapangidwa ndi chitsulo chopindika pambuyo pochiza. Nthawi zambiri, chitsulo chamzerewu chimatulutsidwa, chopangidwa, chophwanyika komanso chowotcherera kuti chipange chitoliro chozungulira, kenako ndikuchikulungitsa mu chitoliro chamzere, kenako ndikudula mu utali wofunikira. Nthawi zambiri 50 zidutswa pa phukusi.
Machubu a square amatha kugawidwa kukhala opanda msoko komanso owotcherera. Machubu opanda msoko amachotsedwa kuchokera ku machubu ozungulira opanda msoko. Square zitsulo chitoliro, wandiweyani khoma lalikulu zitsulo chitoliro, lalikulu m'mimba mwake lalikulu zitsulo chitoliro, osasokonekera lalikulu zitsulo chitoliro, otsika aloyi lalikulu zitsulo chitoliro, 135 * 135 * 10 lalikulu zitsulo chitoliro, lalikulu zitsulo chitoliro kwa nsanja crane, Q345B otsika aloyi lalikulu zitsulo chitoliro, 20 # wopanda msoko lalikulu zitsulo chitoliro
1. Performance index kusanthula kwa square chubu - plasticity
Pulasitiki imatanthawuza kuthekera kwa zida zachitsulo kupanga mapindikidwe apulasitiki (mapindikidwe osatha) popanda kuwonongeka pansi pa katundu.
2. Performance index kusanthula kwa square chubu - kuuma
Kuuma ndi cholozera kuyeza kuuma ndi kufewa kwa zida zachitsulo. Pakali pano, njira yomwe imagwiritsidwa ntchito kwambiri poyezera kuuma popanga ndi indentation hardness. Amagwiritsa ntchito inndenter yokhala ndi geometry inayake kukanikizira pamwamba pa chitsulo choyesedwa pansi pa katundu wina, ndikuzindikira kuuma kwake molingana ndi kuchuluka kwa indentation.
Njira zomwe zimagwiritsidwa ntchito kwambiri ndi Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) ndi Vickers hardness (HV).
3. Performance index kusanthula kwa square chubu - kutopa
Mphamvu, pulasitiki ndi kuuma zomwe takambirana pamwambapa ndi zizindikiro zonse zamakina azitsulo zomwe zili pansi pa static load. M'malo mwake, zida zambiri zamakina zimagwira ntchito mozungulira, pomwe kutopa kumachitika.
4. Performance index index of square tube - impact toughness
Katundu wochita mbaliyo pa liwiro lalikulu amatchedwa impact load, ndipo kuthekera kwachitsulo kukana kulephera pansi pa katundu wake kumatchedwa impact toughness.
5. Magwiridwe index kusanthula chitoliro lalikulu - mphamvu lalikulu zitsulo chitoliro, wandiweyani lalikulu lalikulu zitsulo chitoliro, lalikulu m'mimba mwake lalikulu zitsulo chitoliro, opanda msoko zitsulo chitoliro, otsika aloyi lalikulu lalikulu zitsulo chitoliro, 135 * 135 * 10 lalikulu zitsulo chitoliro, lalikulu zitsulo chitoliro kwa nsanja crane , Q345B otsika aloyi lalikulu zitsulo chitoliro, 20 # opanda msoko lalikulu zitsulo chitoliro
Mphamvu imatanthawuza kukana kwa zida zachitsulo kulephera (kuchuluka kwa pulasitiki mapindikidwe kapena kupasuka) pansi pa katundu wosasunthika. Popeza njira zonyamula katundu zimaphatikizira kupsinjika, kupsinjika, kupindika ndi kukameta ubweya, mphamvuyo imagawidwanso kukhala mphamvu yokhazikika, mphamvu yopondereza, mphamvu yosinthika komanso mphamvu yakumeta ubweya. Nthawi zambiri pamakhala kugwirizana kwinakwake pakati pa mphamvu zosiyanasiyana. Nthawi zambiri, kulimba kwamphamvu kumagwiritsidwa ntchito ngati chizindikiro champhamvu kwambiri.
