SKD11 chishandiso chesimbindeimwe yesimbi dzinoshandiswa zvakanyanya mukugadzira maindasitiri. Ndeyemhuri yesimbi ine kabhoni yakawanda, ine chromium alloy uye inozivikanwa nekudzivirira kwayo kupfeka zvakanaka, kuomarara kwakanyanya, uye kugadzikana kwayo mushure mekupisa. Iyo Japanese Industrial Standard (JIS) inosarudza SKD11 sechinhu chepamusoro-soro chekugadzira madhiri, maturusi ekucheka, uye mapanga emaindasitiri. Chinhu chikuru chinosarudza hunhu uhwu hwakanaka ndiko kuumbwa kwayo kwemakemikari. Chinyorwa chino chinopa ongororo yakadzama yezvikamu zvemakemikari zveSKD11, ichitsanangura basa rechinhu chimwe nechimwe uye kuti chinokanganisa sei mashandiro esimbi mukushandiswa kwakasimba.
Pfupiso yeSKD11 Tool Steel
SKD11 inowanzo enzaniswa neyakaenzana nayo yepasi rose senge D2 muASTM standard uye 1.2379 muDIN standard. Pasinei nekusiyana kudiki muzvimiro zvichienderana nechiyero, kemikari huru inoramba yakafanana. Maumbirwo emakemikoro eSKD11 anosanganisira kuenzana kwekabhoni, chromium, molybdenum, uye vanadium, pakati pezvimwe zvinhu zvidiki. Chimwe nechimwe cheizvi chinoita basa rakakosha mukuona kuti hunhu hwesimbi hunosangana nezvinodiwa zvakanyanya zvekushanda kwakasimba.
Kuumbwa Kwemakemikari Kwakajairika kweSKD11
Tafura inotevera inotsanangura huwandu hwemakemikari akajairika esimbi yeSKD11:
| Chinhu | Zviri Mukati (%) |
|---|---|
| Kabhoni (C) | 1.40 – 1.60 |
| Chromium (Cr) | 11.00 – 13.00 |
| Molybdenum (Mo) | 0.80 – 1.20 |
| Vanadium (V) | 0.20 – 0.50 |
| Manganese (Mn) | 0.20 – 0.60 |
| Silikoni (Si) | 0.20 – 0.60 |
| Phosphorus (P) | ≤ 0.030 |
| Sarufa (S) | ≤ 0.030 |
Makoshero aya anogona kusiyana zvishoma zvichienderana nesimbi inoshandiswa kugadzira zvinhu kana zvinodiwa pakushandisa zvinhu. Zvisinei, anopa ruzivo rwakavimbika rwekushandiswa kwakawanda kwekugadzira zvinhu neinjiniya.
Basa reChemical Element imwe neimwe
Kabhoni (C)
Kabhoni yakawanda muSKD11 iri pakati pe1.40% ne1.60%, zvichiita kuti ive simbi ine kabhoni yakawanda. Kabhoni yakawanda inowedzera kuomarara mushure mekupisa, zvichiwedzera kuramba kupfeka uye kugona kwayo kutakura mutoro. Zvisinei, kabhoni yakawanda inogona kuita kuti simbi iputsike, saka SKD11 inochengetedza chiyero chakanaka chekushanda muchando.
Chromium (Cr)
Nehuwandu hwechromium huri pakati pe11% kusvika 13%, SKD11 inowira muchikamu chesimbi dzine chromium yakawanda. Chromium inopa simba rekudzivirira ngura, inovandudza kuomarara, uye inogadzira chromium carbides dzakaoma dzinowedzera zvakanyanya simba rekudzivirira kupera. Chromium yakawanda iyi inosimbisawo chimiro chesimbi panguva yekupisa.
Molybdenum (Mo)
Molybdenum inowedzerwa kubva pa0.80% kusvika 1.20% kuti iwedzere kusimba uye kudzivirira kuputsika. Inobatsirawo pakusimba kwechipiri panguva yekudziya, zvichiita kuti SKD11 ikodzere zvishandiso zvinoda kuramba kupfeka zvakanyanya pahukuoma hwakanyanya.
Vanadium (V)
Kunyangwe iripo muhuwandu hushoma (0.20% kusvika 0.50%), vanadium inoita basa rakakosha mukuvandudza chimiro chegorosi uye kuvandudza kusakara. Inoumba vanadium carbides, iyo yakaoma zvikuru uye inobatsira kuchengetedza kupinza kwemucheto muzvishandiso zvekucheka.
Manganese (Mn)
Manganese yakawanda muSKD11 inotangira pa0.20% kusvika pa0.60%. Inovandudza kuomarara uye simba rekusunga, ukuwo ichishanda se deoxidizer panguva yekugadzira simbi.
Silikoni (Si)
Silicon, iri pakati pe0.20% ne0.60%, inosimbisa simbi kuburikidza nekuomesa solution yakasimba uye inovandudza kuramba kuoxidation panguva yekupisa. Kufanana nemanganese, inoshandawo se deoxidizing agent.
Phosphorus (P) neSulfur (S)
Phosphorus nesarufa zvinowanzo chengetwa zvakaderera sezvinobvira, kazhinji pasi pe0.030%. Kunyange zvazvo huwandu hudiki huchigona kuwedzera mashandiro, huwandu hwakawandisa hunogona kuderedza kuomarara uye kukonzera kupwanyika.
Mhedzisiro yeKuumbwa kweMakemikari paZvimiro zveMichina
Magadzirirwo chaiwo emakemikari eSKD11 anosarudza mashandiro ayo emakanika:
-
Kuoma Kwakanyanya- Yakawanikwa kuburikidza nehuwandu hwakawanda hwekabhoni nechromium, zvichiita kuti kuomarara kusvike kuHRC 60 mushure mekupisa.
-
Kuramba Kupfeka Kwakanaka– Chromium nevanadium carbides zvinodzivirira kupfeka kwenguva refu pakucheka nekugadzira maturusi.
-
Kugadzikana kweDimensional- Zvinhu zvinobatanidza alloying zvinodzikamisa magadzirirwo e microstructure, zvichiita kuti pave nekukanganiswa kushoma panguva yekurapa kupisa.
-
Kusimba Kwakanaka– Molybdenum inodzivirira kuputsika, ichienzanisa kuomarara nekusagona kubatwa.
Kusanganiswa uku kwezvinhu kunoita kuti SKD11 ishande zvakanaka mukucheka simbi, kutsika simbi, uye mamwe mabasa ane simba guru.
Kurapa Kupisa Kunokanganisa Maitiro Emakemikari
Kurapa kupisa kwakakosha paSKD11 sezvo ichisimudzira kugona kwemakemikari ayo. Maitiro akajairika anosanganisira:
-
Kunyungudutsa– Inopfavisa simbi kuti ivandudze mashandiro ayo isati yaoma zvachose.
-
Kupisa– Inodzivirira kupisa kuvhunduka uye kutsemuka nekuwedzera tembiricha zvishoma nezvishoma.
-
Kuomesa– Kusimbisa tembiricha inosvika 1020–1040°C kuti inyungudise makabhohaidhiretsi uye iwane simba guru rekuomarara.
-
Kudzikisa– Inogadzirwa pa150–200°C kuderedza kushushikana uye kugadzirisa kuomarara kuti ishande zvakanaka.
Munguva yekurapwa nekupisa, zvinhu zvakaita sekabhoni, chromium, uye vanadium zvinobatana kuti zvigadzire makabhohaidhi akaomarara, nepo molybdenum ichibatsira kuchengetedza kusimba.
Mashandisirwo Akajairika eSKD11 Tool Steel
Nekuda kwekuumbwa kwayo kwemakemikoro kwakanyatsorongeka, SKD11 inoshandiswa mumaindasitiri akasiyana-siyana:
-
Basa rinotonhora rinofayekutsika, kubvisa chisimbiso, uye kurova
-
Zvishandiso zvekuchekayesimbi nemapurasitiki
-
Mapazi ekuchekererayekucheka zvinhu zvine simba guru
-
Zvishandiso zvekuumba mipumburuyekugadzira simbi
-
Mapanga eindasitiriyekushandisa pakutsvagazve uye kupwanya
Mashandisirwo aya anoshandisa zvizere kuomarara kweSKD11, kuramba kupfeka, uye kugadzikana kwayo.
SKD11 vs Zvimwe Zvishandiso Zvesimbi - Maonero Emakemikari
Zvichienzaniswa neD2 ne1.2379, kuumbwa kwemakemikari eSKD11 kwakafanana, nekusiyana kudiki kwehuwandu hwevanadium kana molybdenum zvichienderana nechiyero. Kusiyana uku kunogona kukanganisa zvishoma kuramba kupfeka, mashandiro, kana mhinduro yekurapa kupisa, asi mukuita, zvinhu izvi zvinochinjika kune akawanda mashandisirwo.
Kudzora Hunhu muKugadzirwa kweSKD11
Kuve nechokwadi chekuti makemikari eSKD11 anosangana nezvinodiwa zvakakosha kuti pave nekushanda kwakasimba. Vagadziri vane mukurumbira vakaita sesakysteelkuita ongororo yespectrographic uye kuyedza murabhoritari pamatanho akasiyana-siyana ekugadzira. Izvi zvinovimbisa kuti zvinhu zvemakemikari zvesimbi zvinoramba zviri mukati mezvinodiwa, zvichiita kuti zvive zvakavimbika mukushanda kwematurusi akaomarara.
Mhedziso
Kushanda zvakanaka kwesimbi yeSKD11 hakusi tsaona. Dhizaini yayo ine kabhoni yakawanda, ine chromium alloy yakawanda, yakapfuma nemolybdenum nevanadium, inoita kuti simbi ikwanise kuramba kupfekwa zvakanaka, kuomarara, uye kugadzikana. Kunzwisisa kuumbwa kwayo kwemakemikari kwakakosha kuti mainjiniya, mainjiniya, nevagadziri vematurusi vasarudze zvinhu zvakakodzera mashandisirwo avo.
Nekuchengetedza kudzora kwakasimba kwemakemikari ayo, vatengesi vakaita sesakysteelIta shuwa kuti simbi yezvishandiso zveSKD11 inoramba ichisangana nezvinodiwa zvakanyanya zvekugadzirwa kwemazuva ano. Ingave ichishandiswa mumadhiya akagadzirwa nemazvo, mapanga emuindasitiri, kana maturusi ekuumba, kemesitiri yeSKD11 ndiyo hwaro hwekushanda kwayo.
