Nhanganyaya huru yezvinhu zvakabikwa

1. Hunhu hukuru hwesimbi nesimbi uye minda yekushandisa

①Simbi yeKabhoni

Simbi yekabhoni isimbi nesimbi ine ferric carbon alloy ine zvinhu zvekabhoni, zvinowanzova pakati pe0.12% ne2.0%. Zvichienderana nehuwandu hwakasiyana hwekabhoni, simbi yekabhoni yakakamurwa kuita simbi ine kabhoni shoma (kabhoni iri pasi pe0.3%), simbi ine kabhoni iri pakati nepakati (kabhoni iri pakati pe0.3% -0.6%) uye simbi ine kabhoni yakawanda (kabhoni iri pakati pe0.6%). Simbi yekabhoni ine plasticity yakanaka, weldability uye machinability, inoshandiswa zvakanyanya muzvikamu zvekuvaka, zvikamu zvemakanika, kugadzira mota nedzimwe nzvimbo.

②Simbi yeAlloy

Simbi yeAlloy chigadzirwa chesimbi ine zvimwe zvinhu zve alloy (zvakaita se chromium, nickel, molybdenum, nezvimwewo) zvinowedzerwa kubva kusimbi yekabhoni kuti ivandudze hunhu hwayo hwemakanika, kuramba kupisa uye kuramba ngura. Simbi yeAlloy inogona kukamurwa kuita mhando dzakasiyana zvichienderana nehuwandu hwekuwedzera uye mashandiro ezvinhu zvakasiyana zve alloy. Semuenzaniso, simbi ye chromium-molybdenum inowanzoshandiswa mukugadzira mota neindasitiri yendege, uye simbi ye manganese inoshandiswa mukugadzira zvikamu zvisingapfeki.

③Simbi isina ngura

Simbi isina ngura isimbi inodzivirira ngura, zvikamu zvikuru ichromium (kazhinji iri pakati pe10% ne30%) uye nickel. Simbi isina ngura yakakamurwa kuita austenite stainless steel, ferrite stainless steel uye martensite stainless steel. Austenitic stainless steel ine simba rakanaka rekudzivirira ngura uye kugadzirisa, inoshandiswa zvakanyanya mumidziyo yekicheni, kushongedza zvivakwa, michina yemakemikari nedzimwe nzvimbo.

④Simbi yekuumbwa

Simbi yesimbi inoshandiswa mukugadzira maforoma, ine kuomarara kwakanyanya, simba guru, kuramba kupfeka uye kuramba kukanganiswa. Zvichienderana nezvinodiwa pakushandiswa uye maitiro ekugadzira, simbi yeforoma yeindasitiri inogona kukamurwa kuita simbi yeforoma inotonhora, simbi yeforoma inopisa, simbi yeforoma yepurasitiki nedzimwe mhando. Inoshandiswa zvakanyanya muforoma dzepurasitiki, maforoma ekufa nekukanda maforoma nedzimwe nzvimbo.

⑤Pombi yesimbi

Pombi yesimbi rudzi rwepombi yesimbi isina chinhu, inogona kukamurwa kuita pombi yesimbi isina musono uye pombi yesimbi yakasungirirwa zvichienderana nemaitiro ekugadzira. Pombi yesimbi inoshandiswa zvakanyanya mumafuta, indasitiri yemakemikari, kugadzira michina, kuvaka nedzimwe nzvimbo, ine hunhu hwesimba rekutakura, kuramba kumanikidzwa kwakanaka uye kuramba ngura. Pombi yesimbi isina musono yakakodzera kune nharaunda ine kumanikidzwa kwakanyanya uye tembiricha yakakwira, nepo pombi yesimbi yakasungirirwa yakakodzera kune hunyanzvi hwekugadzira nekugadzira.

2. Kurapa kupisa uye kurapwa pamusoro

Hunhu hwesimbi hunogona kuvandudzwa nekupisa uye kurapwa pamusoro. Kurapa kupisa kunosanganisira kunyungudutsa, kupisa kwakajairika, kudzima uye mamwe maitiro, izvo zvinogona kugadzirisa chimiro chesimbi uye kuvandudza kuoma kwayo nesimba. Kurapa pamusoro kunosanganisira galvanizing, spraying, coating nedzimwe nzira, izvo zvinogona kuvandudza kuramba ngura uye runako rwesimbi.

3. mwero wemhando yepamusoro

Mwero wemhando yepamusoro wezvinhu zvesimbi wakakosha kuti chigadzirwa chive chemhando yepamusoro. Zvinodiwa zvesimbi zvinosanganisira mwero wepasi rose (semuenzaniso ASTM, ISO), mwero weEurope (semuenzaniso EN), uye mwero wenyika (semuenzaniso GB, JIS). Simbi yakasarudzwa inogona kuvimbisa kushanda kwayo uye kuvimbika kwayo.
