Simbi Isina Kutenderera Bhawa Ine Hunhu Hwakanaka
Kuumbwa Kwechivakwa
Simbi (Fe): ndiyo chinhu chikuru chesimbi chinowanikwa musimbi isina ngura;
Chromium (Cr): ndiyo chinhu chikuru chinoumba ferrite, chromium pamwe chete neokisijeni zvinogona kugadzira firimu reCr2O3 rinodzivirira ngura, chimwe chezvinhu zvakakosha zvesimbi isingatsvedzeri ngura kuchengetedza ngura, huwandu hwechromium hunowedzera kugona kwekugadzirisa firimu repasi yesimbi, huwandu hwechromium yesimbi isingatsvedzeri simbi hunofanira kunge huri pamusoro pe12%;
Kabhoni (C): chinhu chakasimba chinoumba austenite, chinogona kuvandudza zvakanyanya simba resimbi, pamusoro pekabhoni pakudzivirira ngura inewo mhedzisiro yakaipa;
Nickel (Ni): ndiyo chinhu chikuru chinoumba austenite, inogona kunonoka ngura yesimbi uye kukura kwezviyo panguva yekupisa;
Molybdenum (Mo): chinhu chinoumba carbide, carbide inoumbwa yakasimba zvikuru, inogona kudzivirira kukura kwetsanga ye austenite kana yapiswa, kuderedza kupisa kwakanyanya kwesimbi, pamusoro pezvo, molybdenum inogona kuita kuti passivation film ive yakasimba uye yakasimba, nokudaro ichivandudza zvinobudirira simbi isina ngura Cl- corrosion resistance;
Niobium, titanium (Nb, Ti): zvinhu zvine simba zvinoumba carbide, zvinogona kuvandudza kuramba kwesimbi kubva mukuora kwepakati pegranular. Zvisinei, titanium carbide ine simba rakaipa pamhando yepamusoro yesimbi isingatsvedzeri, saka simbi isingatsvedzeri ine zvinodiwa zvakanyanya pamusoro inowanzo vandudzwa nekuwedzera niobium kuti ivandudze mashandiro.
Nitrogen (N): chinhu chakasimba chinoumba austenite, chinogona kuvandudza simba resimbi zvakanyanya. Asi kupwanyika kwesimbi isingatsvedzi kukwegura kune simba guru, saka simbi isingatsvedzi inoedza kudzora huwandu hwenitrogen zvakanyanya.
Phosphorus, sarufa (P, S): chinhu chinokuvadza musimbi isingatsvi, kuramba ngura uye kudhindwa kwesimbi isingatsvi kunogona kukanganisa zvakanyanya.
Kuratidzwa Kwechigadzirwa
zvemuchadenga uye mashandiro
| Zvinhu | Hunhu |
| 310S simbi isina ngura | Simbi isingatsvi 310S isimbi isingatsvi chromium-nickel ine simba rakanaka rekudzivirira kuoxidation, inodzivirira ngura, nekuda kwehuwandu hwakakwira hwechromium nenickel, 310S ine simba riri nani rekukwira, inogona kuramba ichishanda pakupisa kwakanyanya, inodzivirira kupisa kwakanyanya. |
| 316L simbi isina ngura bhaa rakatenderera | 1) Kupenya kwakanaka uye chitarisiko chakanaka chezvigadzirwa zvinotonhorera zvakaputirwa. 2) kudzivirira ngura kwakanyanya, kunyanya kudzivirira makomba, nekuda kwekuwedzera kweMo 3) simba rakanaka kwazvo rekupisa kwepamusoro; 4) kuomesa basa zvakanaka (simba remagineti mushure mekugadzirisa) 5) isina simba remagineti iri mumamiriro ekugadzirisa kwakasimba. |
| Simbi isina ngura 316 simbi yakatenderera | Hunhu: 316 simbi isingasvibi ndiyo yechipiri inoshandiswa zvakanyanya mushure me304, inonyanya kushandiswa muindasitiri yechikafu nemidziyo yekuvhiya, nekuda kwekuwedzera kweMo, saka kuramba kwayo ngura, kuramba ngura mumhepo uye simba rekupisa kwakanyanya zvakanaka, zvinogona kushandiswa mumamiriro ezvinhu akaoma; kuomesa basa kwakanaka (kusina magineti). |
| Simbi isina ngura 321 simbi yakatenderera | Hunhu: Kuwedzerwa kwezvinhu zveTi kusimbi ye304 kudzivirira ngura yemuganhu wezviyo, yakakodzera kushandiswa patembiricha ye430 ℃ - 900 ℃. Kunze kwekuwedzera zvinhu zvetitanium kuderedza njodzi yekuora kwezvinhu, weld nezvimwe zvinhu zvakafanana ne304. |
| Simbi isina ngura ye304L | Simbi isina ngura ye304L imhando yesimbi isina ngura ye304 ine kabhoni shoma uye inoshandiswa mukushandiswa uko kunodiwa kusanganisa. Kabhoni shoma inoderedza kunaya kwekabhoni munzvimbo ine kupisa pedyo nesimbi inosanganisa, izvo zvinogona kukonzera ngura pakati pegranular granular (weld erosion) yesimbi isina ngura munzvimbo dzakati wandei. |
| Simbi isina ngura 304 simbi yakatenderera | Hunhu: 304 simbi isina ngura ndeimwe yesimbi isinga ngura inoshandiswa zvakanyanya ne chromium-nickel, ine ngura yakanaka, inodzivirira kupisa, simba rakaderera rekupisa uye hunhu hwemakanika. Kudzivirira ngura mumhepo, kana iri munzvimbo dzemaindasitiri kana nzvimbo dzakanyanya kusvibiswa, inofanira kucheneswa nenguva kudzivirira ngura. |
Kushandiswa Kwakajairika
Simbi isina ngura ine mukana wakakura wekushandiswa uye inoshandiswa zvakanyanya mumidziyo yemagetsi neyekicheni, kuvaka ngarava, petrochemical, michina, mishonga, chikafu, simba remagetsi, simba, ndege, nezvimwewo, kuvaka nekushongedza. Midziyo yekushandisa mumvura yegungwa, makemikari, dhayi, bepa, oxalic acid, fetereza nezvimwe zvishandiso zvekugadzira; kutora mifananidzo, indasitiri yechikafu, nzvimbo dzemahombekombe, tambo, maCD rods, mabhoti, nzungu
Zvigadzirwa Zvikuru
Matavi akatenderera esimbi isina ngura anogona kukamurwa kuita ma "hot rolled", "forged" uye "cold drawn" zvichienderana nemaitiro ekugadzira. Zvinodiwa zvesimbi isina ngura yakatenderedzwa yesimbi isina ngura ine 5.5-250 mm. Pakati pawo: 5.5-25 mm yesimbi diki isina ngura inowanikwa mumapaketi ematanda akatwasuka, anowanzo shandiswa sematanda esimbi, mabhaudhi nezvimwe zvikamu zvemakanika; simbi isina ngura yakatenderedzwa inodarika 25 mm, inonyanya kushandiswa mukugadzira zvikamu zvemakanika kana kuti mabhiri esimbi asina musono.
