Kusarudza giredhi resimbi rakakodzera repurojekiti yako isarudzo yakakosha inokanganisa mashandiro, kusimba, uye mutengo wechigadzirwa chako chekupedzisira. Iyo chaiyo simbi giredhi zvinoenderana nezvinhu zvakaita semashandisirwo, zvinodikanwa zvemutoro, mamiriro ekunze, uye chaiwo zvivakwa zvinodiwa. Heino nhanho-ne-nhanho gwara rekubatsira iwe kusarudza yakanakisa simbi giredhi yepurojekiti yako:

1. Ziva Zvinodikanwa zveProjekti Yako

Tanga nekunzwisisa zvakakosha zvinodiwa zvepurojekiti yako:

Mechanical properties: Ndeapi simba, kuoma, uye kuomarara zvinodiwa?

Corrosion resistance: Ko simbi yacho ichave yakaratidzwa kune yakaoma mamiriro ezvakatipoteredza (semuenzaniso, unyoro, makemikari)?

Kushanda: Simbi inoda kuve nyore sei kupinza, muchina, kana fomu?

Tembiricha mamiriro: Simbi yacho ichashandiswa mukupisa kwakanyanya, kungave kupisa kana kutonhora?

Kufunga kwemitengo: Une bhajeti rakasimba here? Masimbi epamusoro-giredhi anowanzo kuuya nemitengo yepamusoro yezvinhu.

2. Nzwisisa Mhando Dzakasiyana dzeSimbi

Simbi inogona kuverengerwa yakasarudzika zvichienderana nekuumbwa kwayo uye kurapwa. Mhando dzinonyanya kuzivikanwa ndeidzi:

• Carbon steel: Rudzi rwakawanda, rune mazinga akasiyana-siyana emukati kabhoni. Yakakwira kabhoni yemukati kazhinji inopa simba rakakura asi inodzikisa ductility.

Yakaderera-kabhoni simbi(Simbi yakapfava): Yakanakira kushandiswa kwese-chinangwa.

Simbi yepakati-kabhoni: Inopa chiyero chesimba uye ductility, chinowanzo shandiswa kune zvimiro zvekushandisa.

High-carbon steel: Yakasimba uye yakaoma asi shoma ductile; inoshandiswa pazvishandiso uye zvikamu zvepamusoro-simba.

• Alloy simbi: Iine mamwe alloying maelementi akaita sechromium, nickel, molybdenum, zvichingodaro. Masimbi aya akagadzirirwa zvinhu zvakaita sesimba rakakwirira, kusaita ngura, kana kupisa kupisa.Specialty steels: Izvi zvinosanganisira maraging simbi, inotakura simbi, uye zvimwe zvinoshandiswa kune chaiwo maapplication senge aerospace uye maindasitiri emotokari.

Simbi isina ngura: Isingadziviriri, inowanzo shandiswa munzvimbo dzine ngura (semuenzaniso, midziyo yekurapa, midziyo yekugadzira chikafu, uye zvirimwa zvemakemikari).

Tool simbi: Yakanyanya kuoma uye inoshandiswa kugadzira maturusi uye inofa.

High-simba yakaderera-alloy (HSLA) simbi: Inopa simba riri nani uye kuramba kuparara kwemuchadenga uku ichireruka pane yechinyakare kabhoni simbi.

3. Tarisa Simba reSimbi

Kusimba simba: Kuwanda kwesimba chinhu chinogona kumira pachiri kutambanudza kana kudhonzwa chisati chapwanyika. Nezvikumbiro zvinotakura mutoro, sarudza giredhi resimbi rine simba rinodiwa rekusimba.

Goho simba: Kunetsekana uko chinhu chinotanga kukanganisa zvachose. Simbi dzesimba regoho repamusoro dzinofarirwa kune zvimiro uye kuchengetedza-yakakosha maapplication.

4. Chimbofunga Kuoma Kwesimbi

Kuoma kwesimbi kwakakosha kune maapplication uko kupfeka kuramba kwakakosha, senge mukucheka maturusi, magiya, kana zvinhu zvemotokari. Masimbi akaomarara haanyanyi kupfekwa nekufamba kwenguva asi anogona kunyanya kuoma muchina kana weld.

5. Factor in Toughness uye Ductility

Kuoma: Kugona kwesimbi kutora simba risati ratsemuka. Izvo zvakakosha kune simbi dzinoshandiswa mukukanganisa-inowanzoitika.

Ductility: Kugona kwesimbi kukanganisa pasi pekunetseka. Kune zvikamu zvichange zvakakotama kana kuumbwa, iwe uchazoda simbi ine ductile inokwana kudzivirira kuputika.

6. Tarisa Corrosion Resistance

Kana simbi ichizoiswa muhunyoro, makemikari, kana mvura yemunyu, kushomeka kwekuora kwakakosha. Simbi dzisina simbi (semuenzaniso, 304, 316) dzinoshingirira zvakanyanya uye dzinowanzo shandiswa mumakungwa, kugadzira chikafu, uye mishonga yekurapa.

7. Tarisa Kugadzira uye Welding Properties

     Weldability: Mamwe mamakisi esimbi ari nyore kupinza kupfuura mamwe. Masimbi akadzika-kabhoni anowanzo kuve nyore kupinza, nepo masimbi epamusoro-kabhoni kana masimbi epamusoro-alloy angangoda midziyo yakasarudzika kana pre-kudziisa kuti usatsemuka.

Formability: Pamapurojekiti anoda kuumbwa kwakakura kana kuumbwa (sekutsika kana kukunguruka), iwe uchada simbi iri nyore kugadzira isingakanganise mashandiro ayo.

8. Funga nezveMaitirwo Ekurapa Kupisa

Masimbi mazhinji anorapwa kupisa kuti awedzere maitiro avo emuchina. Dzimwe simbi (semidziyo yemidziyo) inogona kucheneswa-kupiswa kuti iwane kuomarara kwepamusoro kana mamicrostructures chaiwo. Ita shuwa kuti giredhi raunosarudza rinogona kurapwa rinodiwa kupisa kana richidikanwa pachikumbiro chako.

9. Tarisa Mitemo uye Zvinotsanangurwa

• Tarisa kune akakodzera indasitiri zviyero (semuenzaniso, ASTM, AISI, DIN, SAE) inotsanangura zvivakwa uye zvirevo zvemagiredhi esimbi.
• Wona kuti simbi yaunosarudza inoenderana neakakodzera zviyero zveindasitiri yako kana application, ingave yechimiro, mota, ndege, kana zvimwe.

10.Funga Mutengo uye Kuwanikwa

Kunyange zvazvo simbi dzepamusoro-soro dzinogona kupa zvivakwa zvepamusoro, dzinouyawo nemutengo wepamusoro. Weresa mabhenefiti maererano nemutengo kuti uve nechokwadi chekuti giredhi resimbi rinokwana mukati mebhajeti repurojekiti yako. Zvakare, funga nguva dzekutungamira uye kuwanikwa - mamwe mamakisi esimbi anogona kunge aine nguva refu yekutumira nekuda kwekudiwa kana kugadzirwa.

Muenzaniso Magiredhi esimbi eMashandisirwo Akasiyana:

• Simbi yakapfava (semuenzaniso, A36): Inoshandiswa zvakanyanya mukuvaka, mota, uye zvimiro zvekushandisa uko kune mwero simba uye kuumbwa kunodiwa.
• Stainless Simbi (semuenzaniso, 304, 316): Inoshandiswa muzvishandiso zvinoda kupikisa kwakakwira, senge kugadzira chikafu, midziyo yemakemikari, uye michina yekurapa.
• Tool Steel (semuenzaniso, D2, M2): Yakanakira kucheka maturusi, anofa, uye mold nekuda kwekuoma kwayo uye kupfeka kuramba.
• High-simba Simbi (semuenzaniso, 4140, 4340): Inowanzo shandiswa mumotokari, aerospace, uye inorema michina yekushandisa nekuda kwesimba rayo rakakura uye kuramba kuneta.
• Alloy Steel (semuenzaniso, 4130): Inoshandiswa mumaindasitiri emuchadenga, mota, uye kugadzira uko kusimba, kuomarara, uye kuramba kupfeka kwakakosha.

Mhedziso

Iyo chaiyo simbi giredhi yepurojekiti yako zvinoenderana nekuyeresa zvinhu senge simba, kuoma, kushanda, kusaita ngura, uye mutengo. Gara uchifunga nezve izvo chaizvo zvinodikanwa zvechikumbiro chako, uye funga kubvunza mainjiniya emidziyo kana vatengesi kuti uone kuti iwe unosarudza iyo yakakwana simbi giredhi.
