Seamless simbi pombi ine hollow cross-section uye inoshandiswa muhuwandu hukuru sepombi yekutakura mvura, semapaipi ekutakura oiri, gasi rechisikigo, gasi, mvura uye zvimwe zvinhu zvakasimba.Pombi yesimbi uye simbi yakatenderedzwa uye imwe simbi yakasimba, zvichienzaniswa nekukotama kwakafanana uye simba rekurovera, huremu huremu, isimbi inoyambuka-chikamu simbi, inoshandiswa zvakanyanya mukugadzira zvikamu zvezvimiro uye zvemuchina, senge mafuta ekuchera, madhiraivha emotokari. , bhasikoro mafuremu uye kuvakwa kwesimbi scaffolding inoshandiswa mukugadzira simbi pombi mhete mhete, inogona kuvandudza mashandisirwo emidziyo, kurerutsa nzira yekugadzira, kuchengetedza zvinhu uye nguva yekugadzirisa, yakashandiswa zvakanyanya kugadzira simbi pombi.
Mechanical properties
Steel mechanical properties ndeyekuona kuti simbi yekupedzisira-kushandisa zvinhu (mechanical properties) yezviratidzo zvakakosha, zvinoenderana nemakemikari ekugadzirwa kwesimbi uye kupisa kwehutano.Mune iyo simbi pombi mwero, zvinoenderana neyakasiyana mashandisiro ekushandisa, tsanangura iyo tensile zvivakwa (tensile simba, goho simba kana goho poindi, elongation) uye kuoma, kusimba zviratidzo, pane zvinodiwa nemushandisi zvepamusoro uye zvakaderera tembiricha kuita, nezvimwe.
① Kusimba kwesimba (σb)
Muenzaniso mukukakavadzana, simba repamusoro (Fb) rakamira panguva yekudhonza, rakakamurwa nekushushikana (σ) kunowanikwa kubva kunzvimbo yekutanga yepakati-chikamu (So) yemuenzaniso, inozivikanwa se tensile simba (σb), iyo unit ndeye N/mm2 (MPa).Inomiririra huwandu hwepamusoro hwesimbi inodzivirira kukanganisa mukukakavadzana.Iyo yekuverenga formula ndeye
Ikoko: Fb - simba guru rinotsigirwa nemuenzaniso painodhonzwa, N (Newton);Saka - nzvimbo yepakutanga yemuchinjikwa-chikamu chemuenzaniso, mm2.
②Chipo chekubereka (σs)
Nechiitiko chegoho chezvigadzirwa zvesimbi, muenzaniso mukutambanudza kwesimba hauwedzere (kuramba uripo) unogona kuramba uchirebesa kushushikana, kunonzi goho point.Kana kudonha musimba kukaitika, mutsauko unofanirwa kuitwa pakati peiyo yepamusoro uye yakaderera goho mapoinzi.Iyo unit yegoho poindi iN/mm2 (MPa).
Iyo yekumusoro goho poindi (σsu): iyo yakanyanya kushushikana isati yaburitsa sampuli uye simba rinotanga kudonha;iyo yakaderera goho poindi (σsl): kushoma kushushikana muchikamu chekubereka kana yekutanga yenguva pfupi mhedzisiro isingatariswe.
Chimiro chekuverenga chegoho ndeichi: fomula: Fs - simba regoho (nguva dzose) panguva yekusimba kwemuenzaniso, N (Newton) Saka - yepakutanga-chikamu chechikamu chechikamu chemuenzaniso, mm2.
③ Kurebesa mushure mekuzorora (σ)
Mukuedza kwekusimba, kuwedzera kwehuwandu hwehurefu hwemuenzaniso mushure mekunge hwadhonzwa kubva pachiratidzo chayo kusvika pakureba kwechiratidzo chekutanga kunonzi kurebesa.Inoratidzwa se σ mu%.Yakaverengerwa se: formula: L1 - kureba kwemuenzaniso mushure mekudhonza chiratidzo chayo, mm;L0 - kureba kwechiratidzo chekutanga chemuenzaniso, mm.
④ Fractional shrinkage rate (ψ)
Mukuedza kwekusimba, kuderera kwepamusoro-soro kwechikamu-chikamu chechikamu chemuenzaniso pakuderera kwayo mushure mekudhonza sechikamu chechikamu chepakutanga-chepakati-chepakati nzvimbo inonzi "fractional shrinkage rate".Inoratidzwa se ψ mu %.Iyo calculation formula ndeyotevera
Ikoko: S0 - nzvimbo yepakutanga yemuchinjikwa-chikamu chemuenzaniso, mm2;S1 - iyo shoma-yepakati-chikamu nzvimbo pane shrinkage mushure mekunge sampuli yabviswa, mm2.
⑤ Kuoma indekisi
Kugona kwesimbi kupikisa kupinza kwechinhu chakaoma kupinda pamusoro, chinonzi kuoma.Zvichienderana nebvunzo nzira uye chiyero chekushandisa, kuomarara kunogona kukamurwa kuita Brinell kuomarara, Rockwell kuomarara, Vickers kuomarara, Shore kuomarara, microhardness uye yakakwirira tembiricha kuoma.Nekuti iyo chubhu inowanzo shandiswa kuve neBrinell, Rockwell, Vickers kuomarara matatu.
Shandong Xinjie Metal Materials Co., Ltd. ikambani yesimbi pombi inobatanidza kugadzirwa, kugadzirisa uye kushanda, inonyanya kuita: isina musono pombi yesimbi (yakakobvu-yakakomberedzwa seamless simbi pombi, yakaderera uye yepakati kumanikidza bhaira chubhu, alloy simbi pombi, sikweya nguva pombi. , high pressure boiler chubhu, petroleum inopwanya pombi, chemical fetiraiza pombi, special simbi pombi), stainless (stainless simbi isina musono pombi, stainless steel welded pombi, stainless simbi, pombi/ndiro inounzwa kunze, simbi isina stainless round bar, stainless steel sikweya nguva pombi), Stainless simbi Profile (I-danda, kona simbi, chiteshi simbi) uye zvimwe zvigadzirwa.
