Special product specifications.Ukobvu huri 8-50mm, hupamhi 150-625mm, kureba 5-15m, uye zvinyorwa zvechigadzirwa zvakanyatsoparadzaniswa kuti zvizadzise zvido zvevashandisi, uye zvinogona kushandiswa pachinzvimbo chendiro yepakati, pasina kucheka, uye inogona kugadzirwa zvakananga.
Pamusoro pechigadzirwa chakajeka uye chakachena.Iyo nzira yekudzika kwemvura yakanyanya kuderera inoshandiswa kechipiri.
Mativi maviri akamira uye makona akajeka.Kupfuura kwechipiri kwe vertical rolling mukutenderera kwakanaka kunovimbisa kumira kwakanaka kwemativi ese, makona akajeka uye kunaka kwepamusoro kwemativi.
Chiyero chechigadzirwa chakanyatsojeka, iwo matatu mapoinzi mutsauko uye yakafanana nhanho musiyano uri nani pane mwero wesimbi ndiro;chigadzirwa chacho chakadzika uye chakananga, uye chimiro cheplate chakanaka.Precision rolling inotora inoenderera mberi yekukunguruka, otomatiki live sleeve otomatiki kudzora kuti ive nechokwadi chekuti hapana simbi yakaturikidzana uye pasina simbi inodhonza, yakakwirira dimensional kurongeka kwechigadzirwa, kushivirira renji, matatu mapoinzi musiyano, yakafanana giredhi musiyano, jeko bend uye mamwe ma paramita ari nani pane yepakati. ndiro, uye kutwasuka kwendiro kwakanaka.Cold shear shear, yakanyanya kunaka kwekureba saizi.
Zvigadzirwa zvechigadzirwa zvinotora chiyero chenyika, zvakafanana nesimbi ndiro.Hunhu uye tekinoroji zviyero zvakarongwa uye zvinogadzirwa zvinoenderana neYB/T4212-2010 standard (Q345B/Q235B inoreva GB/T1591-94, zvichiteerana.
1. Hot-yakakungurutswa flat simbi isimbi yakareba, inogona kukungurutswa ine rectangular cross-section kuti ishandiswe zvachose.Madimikira ayo anoratidzwa mumamirimita ehupamhi * upamhi.Simbi yakatsetseka inogona kupedzwa simbi, inoshandiswa kune zvikamu, manera, mabhiriji uye fenzi, etc. Flat simbi inogonawo kushandiswa semabhiliti uye slabs kune welded steel uye laminated sheet.(Zvinhu: Q215, Q235), chiyero chekushandisa: GB704-1988 panzvimbo yeGB704-83, chiyero ichi chinoshanda kune ukobvu hwe3 ~ 60mm, hupamhi hwe10 ~ 200mm, rectangular cross-section ye general-chinangwa chinopisa-yakakungurutswa flat simbi. .Delivery mamiriro: Flat simbi inounzwa mumabhawa akatwasuka.Chiyero: Simbi yakatsetseka yehurefu hwakagadziriswa uye urefu hwevarume hunounzwa nehuremu hwekufungidzira.
2. forged flat steel is forged long steel plate ine rectangular cross-section.Kugadzira hakugone chete kuwana imwe chimiro uye saizi yefogi, asi zvakare inogona kuvandudza zvakanyanya iyo yakakandwa simbi sangano, kuvandudza density yesimbi;inogona kushandura kugoverwa kwefiber sangano, kubvisa anisotropy, kuvandudza michina yesimbi, kuitira kuti simba uye kuoma kwesimbi zvivandudzwe;uye inogona kugadziriswa plasticity yakaderera musimbi yakakwirira uye yakakwirira alloy simbi.Forged flat simbi inonyanya kushandiswa kwepamusoro-mhando alloy simbi, inonyanya kushandiswa kune zvitubu, maturusi uye akakosha emuchina zvikamu.Iyo yekumisikidzwa kwesimbi yakafukidzwa simbi inoratidzirwa mumm yehukobvu * upamhi, uye iyo yakatarwa ndeye 20mm * 40mm ~ 160mm * 300mm.chiyero chekuuraya: GB/T16761-1
Chikamu chesimbi ndeimwe yemhando ina huru dzesimbi (ndiro, chubhu, mhando, waya).Maererano nechimiro chechikamu, chikamu chesimbi chakakamurwa kuva chikamu chakareruka chesimbi uye yakaoma chikamu simbi (chikamu chesimbi).Iyo yekutanga inoreva sikweya simbi, yakatenderera simbi, simbi yakati sandara, makona simbi, simbi ine hexagonal, zvichingodaro;iyo yekupedzisira inoreva I-beam, chiteshi simbi, simbi njanji, hwindo furemu simbi, kubhenda simbi, nezvimwe.
Square simbi - square chikamu simbi, inopisa-yakakungurutswa uye inotonhora-yakakunguruka;inopisa-yakakungurutswa mativi simbi kureba 5-250mm;inotonhora-inodhonzwa mativi simbi kureba 3-100mm.
Round simbi - denderedzwa chikamu chesimbi, yakakamurwa kuita inopisa-yakakungurutswa, yakaumbwa uye inotonhora-yakadhonzwa matatu, inopisa-yakakungurutswa denderedzwa simbi dhayamita 5-250mm, iyo 5-9mm inowanzoshandiswa seyakagadzirwa simbi yekudhirowa waya yesimbi, inonzi waya tsvimbo. ;sekupinda mundiro yekugovera inonziwo hot-rolled coil.Simbi yakaumbwa yakatenderedzwa yakakora, inoshandiswa seshaft billet.Cold-drawn round simbi dhayamita 3-100mm, yakakwirira dimensional kunyatsoita.
Angle simbi - yakakamurwa kuita marudzi maviri esimbi yakaenzana uye isina kuenzana yemakona.Tsanangudzo yesimbi yemakona inoratidzwa nehukuru hwehurefu hwemativi uye kukora kwemativi.Kazhinji zvinotsanangurwa zvemakona simbi inogadzirwa ndeyeNo.Zvakadai seNo. 5 equilateral angle simbi inoreva kudivi kureba kwe5cm (50mm) kona simbi.Nhamba imwechete yemakona inowanzova ne 2-7 akasiyana mativi makobvu.
