Tsanangudzo yeMapurati eSimbi: Kunzwisisa Simba reMashandisirwo eMaindasitiri

Maplate esimbi ndiwo hwaro hwemaindasitiri asingaverengeki, kubva pakuvaka nekuvaka ngarava kusvika kumafuta negesi, michina inorema, uye ndege. Plate yega yega yesimbi inogadzirwa kusvika kumhando dzakatarwa, ichiva nechokwadi chekuti inosangana nezvinodiwa zvesimba, kusimba, kuramba ngura, uye kugona kusveta. Kunzwisisa mamaplate esimbi uye kuyera simba rayo kwakakosha kune mainjiniya, nyanzvi dzekutenga, uye vagadziri vanofanirwa kusarudza zvinhu zvakakodzera zvekushandisa mumaindasitiri.

Chinyorwa chino chinopa tsananguro yakadzama yemagiredhi esimbi, zviyero zvinoatsanangura, uye kuti kuyera kwesimba kunokanganisa sei mashandiro muzvikamu zvakasiyana-siyana.

Chii Chinonzi Magiredhi eSimbi yeSimbi?

Magiredhi esimbi ndiro boka rinotsanangudza hunhu hwemakemikari nemakemikari emaplate esimbi. Magiredhi aya anowanzo tsanangurwa nemasangano epasi rose ekuenzanisa akadai seASTM, ASME, EN, DIN, JIS, uye ISO. Giredhi rega rega rinotsanangura zviyero zvakakosha, zvinosanganisira:

  • Kuumbwa kwemakemikari (zvikamu zvekabhoni, manganese, chromium, nickel, nezvimwewo)

  • Hunhu hwemakanika (simba rekudhonza, simba rekuburitsa, kureba, kuomarara)

  • Mamiriro ekurapa kupisa (akanyungudutswa, akadzima uye akapfava, akajairwa)

  • Kushivirirana kwehukuru uye mamiriro epamusoro

Magiredhi anoshanda semutauro wepasi rose, zvichiita kuti vatengi nevatengesi vagone kutsanangura rudzi rwesimbi inodiwa pabasa.

Zvinhu Zvikuru Mukuongorora Simba reSimbi

Kuyera simba ndeimwe yezvinhu zvakakosha pamhando dzesimbi. Izvi zvinoratidza kugona kwesimbi kutsungirira kushushikana pasina kukundikana. Kuyera simba kwakajairika kunosanganisira:

  • Simba reKusimba:Simbi yakanyanya kushushikana inogona kutsungirira isati yapwanyika.

  • Simba reKubereka:Chikamu chekushushikana apo kushanduka kwechigarire kunoitika.

  • Kureba:Kugona kwechinhu chacho kupfava uye kugona kutambanudza chisati chatyoka.

  • Kuramba Kukanganiswa:Kusimba uye kugona kupinza simba pakupisa kwakasiyana.

Nekuongorora maparamita aya, mainjiniya vanogona kuona kana ndiro yesimbi yakakodzera kushandiswa muchimiro, muchina wekumanikidza, mugungwa, kana muchina wekupisa kwakanyanya.

Standards uye Grades dzeCommon Steel Plate

Maitiro eASTM

Sangano reAmerican Society for Testing and Materials (ASTM) rinopa mamwe emagiredhi esimbi anoshandiswa zvakanyanya:

Simba Ratings muMashandisirwo Emaindasitiri

Indasitiri yekuvaka

Mukuvaka, maplate esimbi anoshandiswa mumatanda, makoramu, uye kusimbisa. Magiredhi akaita seASTM A36 neEN S275 akajairika nekuda kwekugona kwawo kusveta uye kusimba kwakakwana. Kune zvivakwa zvemabhiriji marefu nemabhiriji, maplate akasimba akareba akadai seASTM A572 kana EN S355 ndiwo anonyanya kufarirwa.

Indasitiri yeOiri neGasi

Chikamu chemafuta negasi chinoda maplate esimbi ane simba guru uye anodzivirira nharaunda dzakaoma. Maplate emidziyo yepressure akadai seASTM A516 neEN P355 anoshandiswa zvakanyanya mumatangi, mapaipi, uye mapuratifomu ekunze.

Kuvaka Zvikepe uye Zvemugungwa

Mapureti emvura anoda mapurasitiki akaomarara uye anodzivirira ngura. Mapureti akadai seABS EH36 kana LR AH36 anowanzo shandiswa, zvichiita kuti chivakwa chive chakasimba mumamiriro egungwa akaomarara.

Kugadzira Simba

Maboiler, midziyo yekumanikidza, uye manuclear reactors anoshandisa maplate esimbi anodzivirira kupisa uye anodzivirira kukambaira. Magiredhi akadai seASTM A387 (chromium-molybdenum steel) akagadzirirwa kushandiswa pakupisa kwakanyanya.

Ndege neDziviriro

Simba rakawanda uye hunhu hwakareruka zvakakosha pakubhururuka. Magiredhi akadzima uye akapfava akadai seASTM A514 anopa simba rinodiwa pamotokari dzekudzivirira nezvikamu zvemuchadenga.

Kuyedzwa Kwesimba Kunoitwa Sei

Kuyera simba remaplate esimbi kunosimbiswa kuburikidza nekuyedzwa kwakasimba, kusanganisira:

  • Kuedzwa kweKusimba:Inosarudza goho uye simba rekusimba.

  • Kuedzwa kweMhedzisiro (Charpy V-Notch):Inoongorora kusimba kwayo pakupisa kwakaderera kana kwakakwira.

  • Kuedzwa kweKuoma:Inoyera kuramba kushanduka kweganda.

  • Kuedzwa kweUltrasonic:Inoita kuti maplates asave nezvikanganiso zvemukati.

Miedzo iyi inovimbisa kutevedzera mitemo yepasi rose uye inovimbisa kuvimbika kwezvinhu kune vashandisi vekupedzisira.

Zvakanakira Kusarudza Giredhi reSimbi Rakakodzera

Kusarudza giredhi resimbi rakakodzera kunounza mabhenefiti akawanda:

  • Inovimbisa kuchengetedzeka uye kuvimbika kwechimiro chekushandiswa kwemaindasitiri.

  • Inovandudza mashandiro emuviri kana paine kumanikidzwa kwakanyanya, kumanikidzwa, kana tembiricha.

  • Inoderedza mari yekugadzirisa nekuda kwekugara kwenguva refu.

  • Inopa kutevedzera mitemo yeindasitiri uye zvitupa.

Kusasarudza mamakisi zvisirizvo, kune rumwe rutivi, kunogona kutungamira mukukundikana nguva isati yakwana, kuwedzera kwemitengo, uye kunyange njodzi dzekuchengetedza.

Kuenzanisa Mapurati Akasimba Nesimba Rakaderera

  • Mapurati Ane Simba Rakaderera (semuenzaniso, ASTM A36, S235):Zviri nyore kubatanidza nekugadzira, hazvidhuri, zvakakodzera kuvaka zvakanyanya.

  • Mapurati Ane Simba Rakawanda (semuenzaniso, ASTM A514, EN S690):Dzinopa kugona kwakanyanya kutakura mutoro, kuderedza huremu muzvivakwa, uye dzakanakira kushandiswa kwakaoma.

Sarudzo yacho inoenderana nezvinodiwa papurojekiti, mari yaunoda kushandisa, uye mamiriro ekunze.

Basa reKurapa Kupisa muSimba Ratings

Kurapa kupisa kunoita basa rakakosha pakuona mashandiro esimbi:

  • Kugadzirisa zvinhu:Inonatsa chimiro chezviyo uye inovandudza kusimba.

  • Kudzimisa uye Kugadzirisa:Inowedzera simba nekuomarara uku ichichengetedza ductility.

  • Kunyungudutsa:Inowedzera mashandiro emuchina uye inoderedza kuomarara.

Vagadziri vanosarudza nokungwarira nzira dzekurapa kupisa kuti vawane mwero wakakodzera wezvinhu.

Mafambiro Emangwana Mukushandiswa Kwesimbi Yesimbi

Kudiwa kwemapureti esimbi anoshanda zvakanyanya kuri kuramba kuchikura, zvichikonzerwa ne:

  • Kuvandudzwa kwezvivakwa mune hupfumi huri kusimukira.

  • Mapurojekiti esimba rinogona kudzokororwa anoda zvinhu zvinogara kwenguva refu.

  • Mapureti akareruka uye akasimba ekufambisa nekufambisa ndege.

  • Kuwedzera mitemo yekuchengetedzeka mumaindasitiri akasiyana-siyana.

Nekufambira mberi mukugadzira simbi, mhando itsva dziri kugadzirwa dzinosanganisa simba guru nekuvandudzika kwekudzivirira ngura uye kugona kwayo kugadzira zvinhu.

Sei Uchifanira Kutsvaga Mapurati eSimbi kubva kuSakysteel?

Pakusarudza mapurati esimbi, kuvimbika kwekuwanikwa kwezvinhu kwakakosha sekushanda kwehunyanzvi.sakysteelinopa mhando dzakasiyana dzemhando dzesimbi, ichitevedzera mitemo yeASTM, EN, DIN, uye JIS. Nekushandisa nzira dzekugadzirisa zvinhu dzemazuva ano, kuongororwa kwemhando yepamusoro, uye kurongedza kwakagadzirira kutumirwa kunze kwenyika, vatengi vanogona kuva nechivimbo chemhando yepamusoro uye kutumira.

Kubva kumapurojekiti madiki kusvika kumakondirakiti makuru emaindasitiri,sakysteelinopa mashandiro akasimba uye rutsigiro rwekugovera zvinhu pasi rose, zvichiita kuti ive mubatsiri anovimbwa naye wekushandiswa kwemaindasitiri pasi rese.

Mhedziso

Magiredhi esimbi uye kusimba kwawo ndiwo musimboti weindasitiri yemazuva ano. Kubva pakuvaka nesimba kusvika pakuvaka ngarava nendege, kushandiswa kwese kunoda kusarudzwa kwakanyatsonaka kwezvinhu kuti ive nechokwadi chekuti yakachengeteka, inoshanda zvakanaka, uye inobudirira pamutengo.

Nekunzwisisa kupatsanurwa, hunhu hwemakanika, uye nzira dzekuyedza magiredhi esimbi, nyanzvi dzekutenga nemainjiniya vanogona kuita sarudzo dzakavakirwa paruzivo dzakagadzirwa zvinoenderana nezvinodiwa nemapurojekiti avo. Sezvo maindasitiri achiramba achichinja, mapurasitiki esimbi anoshanda zvakanyanya acharamba achikosha pakuvandudza nekufambira mberi.
