1. Nguva dzose ngura uye anti-corrosion kudzivirira
Kazhinji, chimiro chesimbi ndeye 5O-70 makore mukugadzira uye kushandisa nguva.Panguva yekushandiswa kwekugadzirwa kwesimbi, mikana yekukuvara nekuda kwemutoro mukuru idiki.Kukuvadzwa kwesimbi kwakawanda kunokonzerwa nekudzikiswa kwemaitiro mechanics uye zvinhu zvemuviri zvinokonzerwa nengura.Iyo "Snueling of Steel Structure Design" ine zvimwe zvinodiwa zvesimbi chimiro anticorrosion yave ichishandiswa kweanopfuura makore makumi maviri nemashanu.Nokudaro, zvinotarisirwa kusangana nezvinodiwa zvekugadzirwa kwesimbi kunze kwechimiro chesimbi.Kazhinji, chimiro chesimbi chinotora makore matatu kuchengetedza kuchengetedza (kuchenesa guruva muchimiro chesimbi, ngura, uye imwe tsvina isati yatsvaira coating).Izvo zvakasiyana-siyana uye zvinyorwa zvepende zvinofanira kunge zvakafanana nekugadzirwa kwepakutanga, kana zvikasadaro zvipfeko zviviri zvisingaenderani zvichaunza kukuvadza kukuru, uye vashandisi vanofanira kuchengetedzwa zvakanaka uye kuchengetedzwa nenzira yakarongwa.
Kudzivirira simbi yekugadzira ngura: Munguva yekupedzisira yekugadzirisa nekugadzirisa, isiri-simbi yekuvhara nzira yekudzivirira inonyanya kushandiswa.Inodzivirirwa nekuputira uye epurasitiki pamusoro pechikamu, kuitira kuti irege kubata yakakomberedza midhiya inoparadza kuti iwane chinangwa cheanticorrosion.Iyi nzira ine mhedzisiro yakanaka, mitengo yakaderera, uye akawanda emhando dzekupfeka.Inowanikwa kune zvakasiyana-siyana zvekusarudza, kushandiswa kwakasimba, uye zvirambidzo pachimiro uye ukuru hwechikamu.Chikamu chakadzoserwa uye chiri nyore kushandisa.Iwe unogonawo kupa zvikamu chimiro chakanaka.
2. Nguva dzose kudzivirira kurapwa kwemoto
Kupisa kwekushisa kwesimbi kwakashata, uye zvinhu zvakawanda zvinoshanduka nekushisa.Kana tembiricha yasvika 430-540 ° C, iyo goho poindi, tensile simba uye elastic modulus yesimbi inodonha zvakanyanya uye kurasikirwa nekutakura.Izvo zvinodikanwa kushandisa refractory zvinhu kuchengetedza chimiro chesimbi.Yakanga isati yagadziriswa nependi isingapindi moto.Iko refractory kugona kwechivako kunoenderana nekupikisa moto kwechikamu chekuvaka.Apo moto unoitika, simba rayo rekutakura rinofanira kukwanisa kuenderera mberi kwenguva yakati, kuitira kuti vanhu vagone kubuda zvakachengeteka, kununura zvinhu uye kudzima moto.
Matanho ekudzivirira moto ndeaya: saka iyo yakafumurwa simbi chikamu chebhurashi chekudzivirira moto machira, izvo zvinodiwa ndezvi: nguva yekuramba yesimbi yesimbi ndeye 1.5h, uye nguva yekuramba yesimbi simbi ndeye 2.5h, iyo inoita kuti iite zvinodiwa. yezvakatemerwa zvezvivakwa.
3. Nguva dzose deformation kutarisa uye kugadzirisa
Kuparadzwa kwesimbi yakagadzirwa nesimbi kune chikamu haisi kungoratidzwa chete sekutetepa kwechikamu chinoshanda chechikamu, asiwo "gomba remarara" rinogadzirwa nechikamu chepamusoro.Iyo yekare yakaderedza kutakura kwechikamu chechikamu, izvo zvakaita kuti huwandu hwekutakura huwandu hwechimiro chesimbi hudzike, uye chimiro chesimbi yakaonda-yakavezwa uye simbi yakareruka yakanga yakanyanya kuoma.Iyo yekupedzisira inokonzera "stress concentration" chiitiko chechimiro chesimbi.Apo chimiro chesimbi chingaitika, chimiro chesimbi chinogona kuitika kamwe kamwe.Iko hakuna deformation zviratidzo kana chiitiko ichi chikaitika, uye hazvisi nyore kuona uye kudzivirira pachine nguva.Kuti izvi zviitike, kushushikana, deformation uye kutsemuka kwekutarisa kwesimbi zvimiro uye makuru zvikamu zvakakosha.
Deformation monitoring: Kana iyo simbi dhizaini yakawandisa deformation panguva yekushandiswa nhanho, inoratidza kuti kutakura kutakura kana kugadzikana kwesimbi chimiro hachichakwanisa kusangana nezvinodiwa zvekushandisa.Panguva ino, muridzi anofanirwa kusungirirwa zvakakwana kuti akurumidze kuronga vanhu vakakodzera muindasitiri kuti vaongorore chakakonzera deformation.Hurongwa hwehutongi hunotsanangurwa uye hunoitwa nekukasira kudzivirira kukuvadzwa kukuru kweinjiniya yesimbi.
4. Nguva dzose kuongorora uye kuchengetedza zvimwe zvirwere
Paunenge uchiita manejimendi ezuva nezuva uye kugadzirisa kwesimbi chimiro engineering, kunze kwekuteerera kuongororwa kwechirwere che ngura, iwe unofanirwawo kutarisisa kune zvinotevera zvinhu:
(1) Kunyangwe kubatanidzwa kwewelds, mabhaudhi, rivets, nezvimwewo kunoitika pakubatanidzwa kwepakatsemuka, kusunungura, uye kutsemuka senge makatsemuka.
(2) Kunyangwe izvo zvikamu zvakaita sedanda rega rega, dumbu, bhodhi rekubatanidza, nezvimwe zvine deformation yenzvimbo yakawandisa uye kana paine kukuvara.
(3) Kana iyo yese deformation deformation haina kujairika uye kana paine yakajairika deformation renji.
Kuongorora kwezuva nezuva manejimendi uye kugadzirisa: Kuti uwane panguva yakakodzera zvirwere zvataurwa pamusoro apa uye zvisingaite uye kudzivirira mhedzisiro yakakomba, muridzi anofanirwa kuita ongororo yenguva dzose yesimbi chimiro.Paunenge uchibata kukura kwayo uye shanduko, chikonzero chekuumbwa kwechirwere uye chiitiko chisina kujairika chinofanira kuwanikwa.Kana zvichidikanwa, kuburikidza nekuongorora kwakarurama kwezvinyorwa, zvinowanikwa kubva pakugadzirisa kwesimba, kuoma, uye kugadzikana kwechimiro chesimbi.
