Stainless simbi chinhu chakakurumbira chinoshandiswa mukugadzira nekuda kwesimba rayo, kusimba, uye kuramba corrosion.Nekudaro, inogona zvakare kuunza matambudziko mukuita machining nekuda kwekuoma kwayo uye maitiro ekuomesa-basa.
Heano mamwe akakosha ekufunga kana uchigadzira Stainless simbi:
Kusarudza Tool:
Kusarudza chishandiso chakakodzera kwakakosha pakugadzira simbi isina tsvina.Zvishandiso zvesimbi zvekumhanya zvakanyanya zvakakodzerwa neakaderera-vhoriyamu machining, nepo carbide maturusi akakodzera zviri nani kugadzirwa kwehuwandu.Zvishandiso zvakavharwa zvinogonawo kuvandudza mashandiro uye hupenyu hwematurusi.
Kucheka kumhanya:
Simbi isina tsvina inoda kukurumidza kucheka kunononoka pane zvinyoro zvinyoro kudzivirira kupisa uye kushanda kuoma.Yakakurudzirwa kucheka kumhanya siyana kwesimbi isina tsvina ndeye 100 kusvika 350 sfm (tsoka dzepamusoro paminiti).
Feed rate:
Chiyero chekudya chesimbi isina tsvina chinofanira kudzikiswa kudzivirira kuoma kwebasa uye kupfeka kwemidziyo.Iyo yakakurudzirwa chiyero chekudya chinowanzo 0.001 kusvika 0.010 inches pazino.
Inotonhorera:
Inotonhorera yakafanira yakakosha pakugadzira simbi isina tsvina.Mvura-inonyungudika inotonhorera inosarudzwa pane inotonhorera-inotonhorera kuti isasvibisa uye kuita ngura.High-pressure coolant inogonawo kugadzirisa chip evacuation uye hupenyu hwekushandisa.
Chip control:
Ssimbi isina tsvina inogadzira machipisi akareba, ane tambo anogona kunetsa kudzora.Kushandisa chip breakers kana chip evacuation masisitimu anogona kubatsira kudzivirira chip clogging uye kukuvara kwechishandiso.
Simbi isina ngura ndiko kudimburirwa kwesimbi isina asidi-resistant simbi.Magiredhi esimbi anoshingirira kune zvisina kusimba zvinoodza media zvakaita semhepo, chiutsi, uye mvura, kana zvine zvinhu zvisina tsvina anonzi simbi isina simbi;Corrosion) Simbi yakaora inodaidzwa kuti acid-resistant simbi.
Simbi isina simbi inoreva simbi inoshingirira kune zvisina kusimba zvinoodza media zvakaita semhepo, chiutsi, mvura, uye zvinosvibisa makemikari media senge acid, alkali, uye munyu.Inonziwo Stainless acid-resistant simbi.Mumashandisirwo anoshanda, simbi inoshingirira kune isina kusimba ngura inowanzodaidzwa kunzi Stainless simbi, uye simbi inoshingirira kumakemikari epakati corrosion inodaidzwa kuti acid-resistant simbi.Nekuda kwemusiyano wekuumbwa kwemakemikari pakati pezviviri izvi, yekutanga haigone kurwisa kemikari media corrosion, nepo iyo yekupedzisira kazhinji isina tsvina.Iyo corrosion resistance yesimbi isina tsvina inobva pane alloying zvinhu zviri musimbi.
Zvikamu zvakajairika:
Kazhinji yakakamurwa kuita metallographic sangano:
Kazhinji, simbi yakajairwa isina tsvina yakakamurwa kuita zvikamu zvitatu zvinoenderana nechimiro chemetallographic: austenitic simbi isina tsvina, ferritic simbi isina tsvina, uye martensitic simbi isina tsvina.Pahwaro hwemhando idzi nhatu dzezvimiro zvesimbi, duplex simbi, kunaya kunoomesa simbi dzisina tsvina, uye simbi dzepamusoro-soro dzine simbi isingasviki 50% inotorwa kune chaiyo zvinodiwa uye zvinangwa.
1. Austenitic simbi isina tsvina.
Iyo matrix inonyanya kuumbwa neaustenite chimiro (CY chikamu) ine kumeso-yakatarisana cubic crystal chimiro, isiri-magnetic, uye inonyanya kusimbiswa nekushanda kunotonhora (uye inogona kutungamira kune mamwe magineti zvimiro) simbi isina tsvina.IAmerican Iron and Steel Institute yakanyorwa nenhamba mumazana maviri nemazana matatu akatevedzana, akadai se304.
2. Ferritic simbi isina tsvina.
Iyo matrix inonyanya kuita ferrite (chikamu) ine body-centered cubic crystal structure.Iyo ine magineti uye kazhinji haigone kuomeswa nekupisa kurapwa, asi kutonhora kushanda kunogona kuita kuti isimbiswe zvishoma.IAmerican Iron uye Steel Institute ine 430 uye 446.
3. Martensitic simbi isina tsvina.
Iyo matrix ndeye martensitic (body-centered cubic kana cubic), magineti, uye maitiro ayo emagetsi anogona kugadziriswa nekupisa kurapwa.IAmerican Iron uye Steel Institute ine 410, 420 uye 440 nhamba.Martensite ine austenite chimiro pakupisa kwepamusoro, uye kana yatonhodzwa kusvika kukamuri tembiricha pamwero wakakodzera, iyo austenite chimiro chinogona kushanduka kuita martensite (kureva, kuoma).
4. Austenitic-ferritic (duplex) simbi isina tsvina.
Iyo matrix ine zvese austenite uye ferrite maviri-chikamu chimiro, uye zviri mukati mechikamu chidiki matrix kazhinji chinopfuura 15%.Iyo magnetic uye inogona kusimbiswa nekushanda kunotonhora.329 ndiyo yakajairika duplex simbi isina tsvina.Kuenzaniswa neaustenitic Stainless simbi, duplex simbi ine simba rakawanda, intergranular corrosion resistance, chloride stress corrosion resistance uye pitting corrosion resistance inovandudzwa zvakanyanya.
5. Kunaya kunoomesa simbi isina tsvina.
Iyo matrix ndeye austenite kana martensite, uye inogona kuomeswa nekunaya kwemvura inoomesa simbi isina tsvina.IAmerican Iron and Steel Institute yakanyorwa ne600 akatevedzana manhamba, akadai se630, ayo ari 17-4PH.
Kazhinji kutaura, kunze kwealloys, iyo corrosion resistance ye austenitic stainless simbi yakanaka.Munzvimbo isina kupisa, ferritic simbi isina tsvina inogona kushandiswa.Munzvimbo inoodza zvinyoro nyoro, kana zvinhu zvichidikanwa kuve neSimba rakakwirira kana kuomarara kwepamusoro, martensitic Stainless simbi uye kunaya kwemvura inoomesa simbi isina tsvina inogona kushandiswa.

Musiyano wekukora
1. Nokuticnc milling simbimuchina uri mukukungurutswa, mipumburu inokanganiswa zvishoma nekupisa, zvichikonzera kutsauka muukobvu hwemahwendefa akakungurutswa, ayo anowanzo kukora nepakati uye akatetepa mativi ese.Pakuyera ukobvu hwebhodhi, nyika inotaura kuti chikamu chepakati chemusoro webhodhi chinofanira kuyerwa.
2. Chikonzero chekushivirira ndechokuti maererano nemusika uye zvinodiwa nevatengi, zvinowanzoparadzaniswa kuva kushivirira kukuru uye kushivirira kuduku: semuenzaniso.
Imhando ipi yesimbi isina tsvina isiri nyore kuita ngura?
Pane zvinhu zvitatu zvakakosha zvinokanganisa kukora kwemachined Stainless steel:
1. Zviri mukati me alloying elements.
Kazhinji kutaura, simbi ine chromium inokwana 10.5% haisi nyore kuita ngura.Iyo yakakwira zvirimo zvechromium uye nickel, zviri nani kupikisa kwekuora.Semuenzaniso, zviri mukati nickel mu304 zvinhu zvinofanirwa kunge zviri 8-10%, uye zvirimo muchromium zvinofanirwa kusvika 18-20%.Simbi yakadaro isina tsvina haigoni kuita ngura mumamiriro ezvinhu akajairika.
2. Kunyunguduka kwebhizimusi rekugadzira kuchakanganisawo kushora kwesimbi yesimbi isina tsvina.
Mafekitori makuru esimbi asina simbi ane yakanaka yekunyungudutsa tekinoroji, midziyo yepamusoro uye tekinoroji yepamusoro inogonainovimbisa kutonga kwezvinhu zvealloy, kubviswa kwetsvina, uye kutonga kwebillet kutonhora tembiricha.Nokudaro, hutano hwechigadzirwa hwakagadzikana uye hwakavimbika, hune hutano hwakanaka hwemukati uye hazvisi nyore kuita ngura.Pane zvinopesana, mamwe madiki esimbi ane midziyo yekudzokera kumashure uye kumashure tekinoroji.Munguva yekunyunguduka, tsvina haigoni kubviswa, uye zvigadzirwa zvinogadzirwa zvichange zvisingadzivisiki kuita ngura.
3. Nzvimbo yekunze, yakaoma uye inofefetera zvakanaka haisi nyore kuita ngura.
Hunyoro hwemhepo hwakakwirira, kuenderera mberi kwekunaya kwemvura, kana nzvimbo yezvakatipoteredza ine pH yakakwirira mumhepo iri nyore kuita ngura.304 simbi isina tsvina, kana nharaunda yakatenderedza yakanyanyisa kuipa, inoita ngura.
Nzira yekubata nayo ngura mavara pasimbi isina tsvina?
1. Chemical nzira
Shandisa pickling cream kana kupfapfaidza kubatsira kudzoreredza kwezvikamu zvine ngura kuumba chromium oxide firimu kudzoreredza kuramba kwecorrosion.Mushure mekutora, kuitira kubvisa zvose zvinosvibisa uye masara easidhi, zvakakosha zvikuru kushambidza zvakanaka nemvura yakachena.Mushure mekurapa kwese, porazve nemidziyo yekupolisha uye simbisa newakisi yekupolisha.Kune avo vane makwapa mashoma, unogona kushandisa 1: 1 musanganiswa wepeturu nemafuta einjini kuti udzime nzvimbo dzine ngura nemucheka wakachena.
2. Mechanical nzira
Kuputika kwejecha, kuputika kwepfuti negirazi kana zvimedu zveceramic, kuparara, kukwesha nekupukuta.Zvinogoneka kupukuta nemanenji kusvibiswa kubva pane zvakambobviswa, zvinhu zvekupolisha kana zvinhu zvinodzima.Mhando dzese dzekusvibiswa, kunyanya simbi dzekunze, dzinogona kuita ngura, kunyanya munzvimbo dzine mwando.Naizvozvo, nzvimbo dzakacheneswa nemichina dzinofanirwa kucheneswa zvakanaka pasi pemamiriro akaoma.Kushandiswa kwemichina nzira kunogona chete kuchenesa pamusoro, uye haigoni kuchinja corrosion resistance yechinhu chacho pachayo.Naizvozvo, zvinokurudzirwa kukwenenzvera zvakare nemidziyo yekupolisha mushure mekuchenesa mechini uye nekusimbisa newakisi yekupolisha.
