2, carbon structural simbi

Carbon simbi inoshandiswa muzvivakwa, mabhiriji, ngarava, mota uye zvimwe zvimiro, izvo zvinofanirwa kunge zvine rimwe simba, zvinokanganisa zvivakwa uye welding zvivakwa kana zvichidikanwa.

3. Simbi yekuvaka chimiro

Simbi inoshandiswa pakuvaka zvivako zvirefu uye zvivako zvakakosha.Zvinodikanwa kuve nehupamhi hwekuomarara, simba rakakwana, kuita kwakanaka welding, imwe flexural simba reshiyo, uye ukobvu hwekutungamira kuita kana zvichidikanwa.

4. Simbi yemabhiriji

Simbi inoshandiswa mukuvaka njanji uye nzira huru Bridges.Inodiwa kuve nesimba repamusoro uye kusimba kwakakwana, kuderera kwechinoti chekunzwa, kunaka kwakadzika tembiricha kusimba, kuchembera kunzwa, kuneta kuramba uye kuita welding.Simbi huru ndeye Q345q, Q370q, Q420q uye imwe yakaderera alloy yakakwirira simba simbi.

5. Hull simbi

Welding yakanaka uye zvimwe zvivakwa, zvakakodzera kugadzirisa chimiro chikuru chechikepe uye chikepe hull simbi.Simbi yengarava inodiwa kuti ive yesimba repamusoro, kusimba kuri nani, kugogodza kuramba uye kudonha kwemvura yakadzika kuramba.

6. Simbi yekumanikidza midziyo

Simbi inoshandiswa mukugadzira midziyo yekumanikidza petrochemical, gasi kupatsanurwa uye gasi kuchengetedza uye zvekufambisa zvekushandisa.Inodiwa kuve nesimba rakakwana uye kuoma, kuita kwakanaka welding uye kutonhora uye kupisa kugona kugadzirisa.Simbi inowanzoshandiswa inonyanya kuderera alloy yakakwirira simba simbi uye kabhoni simbi.

7, yakaderera tembiricha simbi

Pakugadzirwa kwemidziyo yekumanikidza uye zvimiro zvekushandisa pazasi -20 ℃, masimbi ane yakanaka yakaderera tembiricha kuoma uye welding zvivakwa zvinodiwa.Zvinoenderana nekupisa kwakasiyana, simbi huru ndeye yakaderera alloy yakakwira simba simbi, nickel simbi uye austenitic Stainless simbi.

8, bhaira simbi

Simbi inoshandiswa mukugadzira superheater, main steam pombi, mvura yemadziro pombi uye boiler chigubhu.Izvo zvinodikanwa kuve neakanaka ma mechanical zvivakwa pakamuri tembiricha uye tembiricha yakakwira, oxidation uye alkaline corrosion resistance, yakaringana simba rakasimba uye rinogara rakaputsika plasticity.Simbi huru inonzi pearlite heat resistant simbi (chromium-molybdenum steel), austenitic heat resistant steel (chromium-nickel steel), high quality carbon steel (20 simbi) uye low alloy high simba simbi.

9. Pipeline simbi

Simbi yemafuta uye gasi rechisikigo refu nguva yekuparadzanisa pombi mutsetse.Iyo yakaderera alloy yakakwira simba simbi ine simba rakakura, kusimba kwakanyanya, yakanakisa machinability, weldability uye corrosion resistance.

10, yakakwira simba resimbi inoburitsa simba uye tensile simba rinopfuura 1200MPa uye 1400MPa zvichiteerana.Hunhu hwayo hukuru hwakanyanya simba, kusimba kwakakwana, kunogona kumira kushushikana kwakanyanya, panguva imwechete ine simba rakawanda rakananga, kuitira kuti chimiro chakanyanya kudzikisa uremu.

11. Kuenzaniswa neyakajairwa kabhoni structural simbi, yakakwira mhando kabhoni structural simbi ine yakaderera yemukati yesarufa, phosphorus uye isiri-metallic inclusions.Zvinoenderana nekabhoni yemukati uye akasiyana mashandisiro, yakakamurwa kuita yakaderera kabhoni simbi, yepakati kabhoni simbi uye yakakwira kabhoni simbi, nezvimwewo, inonyanya kushandiswa kugadzira michina zvikamu uye zvitubu.

12. Alloy structural simbi

Pahwaro hwekabhoni structural simbi ine zvakakodzera alloying zvinhu, inonyanya kushandiswa kugadzira simbi yemechani zvikamu nehukuru hwechikamu chikamu.Iine kuoma kwakakodzera, simba repamusoro, kuoma uye kuneta simba uye yakaderera brittle shanduko tembiricha mushure mekuenderana kupisa kurapwa.Iri rudzi rwesimbi rinonyanya kusanganisira kuomesa uye kupisa simbi, pamusoro pesimbi inoomesa uye inotonhora yepurasitiki kugadzira simbi.

13. Simbi inodzivirira kupisa

Alloy simbi ine simba rakawanda uye yakanaka kugadzikana kwemakemikari pakupisa kwakanyanya.Kusanganisira oxidation - resistant simbi (kana inonzi kupisa - resistant simbi) uye kupisa - yakasimba simbi mapoka maviri.Oxidation inodzivirira simbi inowanzoda kugadzikana kwemakemikari kuri nani, asi inotakura mitoro yakaderera.Thermal simba simbi inoda yakakwira tembiricha simba uye akati wandei oxidation kuramba.

14, weathering simbi (atmospheric corrosion resistant simbi)

Wedzera mhangura, phosphorous, chromium, nickel uye zvimwe zvinhu kuti uvandudze mhepo inodzivirira yesimbi.Rudzi urwu rwesimbi rwakakamurwa kuita simbi dzepamusoro uye simbi yekushongedza mamiriro ekunze.
