Vanhu vanowanzotenga simbi isati yapera, iyo inowedzera kuoma kwezvinhu izvo vashandi vanofanira kufunga nezvazvo.
Kufanana nemidziyo yakawanda, simbi isina tsvina ine zvakawanda zvakanakira nezvayakaipira.Simbi inonzi "stainless simbi" kana alloy iine kanenge 10.5% chromium, iyo inoumba oxide layer ichiita kuti asidhi uye kusaora.Uku kuramba kwecorrosion kunogona kuvandudzwa nekuwedzera chromium yemukati uye nekuwedzera mamwe alloying ekuwedzera.
Iyo "stainless simbi" zvinhu zvekushandisa, kuderera kwekuchengetedza, kusimba uye kwakasiyana-siyana kwepamusoro kupera kunoita kuti ive yakakodzera kune maindasitiri akadai sekuvaka, fenicha, chikafu uye chinwiwa, zvekurapa uye zvimwe zvakawanda zvinoshandiswa zvinoda kusimba uye kusagadzikana kwesimbi.
Simbi isina tsvina inowanzova inodhura kupfuura mamwe masimbi.Nekudaro, inopa simba-ku-huremu mabhenefiti nekubvumira zvinhu zvakatetepa pane zvakajairwa mamakisi, izvo zvinogona kuguma nemutengo wekuchengetedza.Nekuda kwemutengo wayo wese, zvitoro zvinofanirwa kuve nechokwadi kuti zvinoshandisa maturusi akakodzera kudzivirira kutambisa inodhura uye kugadzirisazve chinhu ichi.
Simbi isina tsvina inowanzoonekwa seyakaoma kupinza nekuti inobvisa kupisa nekukasira uye inoda kungwarirwa kukuru panguva yekupedzisa nekupukuta matanho.
Kushanda nesimbi isina tsvina kunowanzoda ane ruzivo rwakanyanya welder kana opareta pane kushanda nekabhoni simbi, iyo inowanzova yakagadzikana.Kufara kwayo kunogona kuderedzwa nekuunza mamwe ma parameter, kunyanya kana welding.Nekuda kwemutengo wakakwira wesimbi isina tsvina, zvine musoro kuti vashandise vane ruzivo vazvishandise.
"Vanhu vanowanzotenga simbi isina tsvina nekuda kwekupedza kwayo," akadaro Jonathan Douville, maneja wechigadzirwa chepamusoro, R&D International, Walter Surface Technologies, Pointe-Claire, Que. "Vanhu vanowanzotenga simbi isina tsvina nekuda kwekupedza kwayo," akadaro Jonathan Douville, maneja wechigadzirwa chepamusoro, R&D International, Walter Surface Technologies, Pointe-Claire, Que. «Люди обычно покупают нержавеющую сталь из-за ее отделки», — сказал Джонатан Доувиль, старший менеджер по продуктам R&D International, Walter Que-Cnologies Surface Technologies. "Vanhu vanowanzotenga simbi isina tsvina kuti ipedze," akadaro Jonathan Douville, Senior Product Manager, R&D International, Walter Surface Technologies, Pointe-Claire, Que."Vanhu vanowanzotenga simbi isina tsvina kuti ipedze," anodaro Jonathan Douville, maneja mukuru wezvekutsvagisa pasi rose nebudiriro paWalter Surface Technologies muPointe Claire, Quebec."Izvi zvinowedzera kune zvipingamupinyi zvinofanirwa kutariswa nevashandisi."
Ingave iri saizi 4 mutsara wekushongedza kana saizi 8 girazi kupera, mushandisi anofanira kuona kuti zvinhu zvacho zvakapfava pane izvo uye kuti iyo yekupfeka haina kukuvara panguva yekubata nekugadzirisa.Iyo inogona zvakare kudzikisira kugadzirira uye yekuchenesa sarudzo, izvo zvakakosha kune mhando yekugadzirwa kwechikamu.
"Paunenge uchishanda nechinhu ichi, chinhu chekutanga kuita kuve nechokwadi kuti chakachena, chakachena uye chakachena zvakare," akadaro Rick Hathelt, PFERD Area Maneja weCanada, Ontario, Mississauga, Ontario."Zvakakosha kuve neshuwa kuti une yakachena (isina kabhoni) mumhepo paunenge uchichenesa simbi isina tsvina kuti ubvise tsvina inogona kuzokonzera oxidation (ngura) uye kudzivirira iyo passivation layer kubva pakupora nekugadzira inodzivirira yekudzikisa oxidation.”
Paunenge uchishandisa simbi isina tsvina, zvinhu uye zvakatipoteredza zvinofanira kucheneswa.Kubvisa oiri nepurasitiki zvakasara kubva kune zvinhu kutanga kwakanaka.Zvinosvibisa pasimbi isina tsvina zvinogona kukonzera oxidation, asi zvinogona zvakare kugadzira matambudziko panguva yekushongedza uye kukonzera kukanganisa.Nokudaro, zvakakosha kuchenesa pasi pamberi pekutengesa.
Nzvimbo yemusangano haisi nguva dzose yakachena uye yakasvibiswa inogona kuva dambudziko kana uchishanda nesimbi isina tsvina uye kabhoni.Kazhinji chitoro chinomhanyisa mafeni mazhinji kana kushandisa maairconditioner kutonhodza vashandi, izvo zvinogona kusundira zvinosvibisa pasi kana kukonzera kudonha kana condensation kuti ivake pazvinhu zvakabikwa.Izvi zvakanyanya kuoma kana kabhoni simbi particles inofuridzirwa pasimbi isina tsvina.Kupatsanura zvinhu izvi uye kuzvichengeta munzvimbo yakachena kwakakosha kana zvasvika pakukwenenzvera welding.
Zvakakosha kubvisa ruvara kuitira kuti ngura irege kuvaka nekufamba kwenguva uye kuderedza chimiro chese.Zvakanakawo kubvisa bluing kuti kunyange kunze kweruvara rwepamusoro.
MuCanada, nekuda kwekutonhora kwakanyanya uye mamiriro ekunze echando, zvakakosha zvikuru kusarudza giredhi rakakodzera resimbi isina tsvina.Douville akatsanangura kuti zvitoro zvakawanda pakutanga zvakasarudza iyo 304 nekuda kwemutengo wayo.Asi kana chitoro chaizoshandisa chinhu ichi kunze, vangakurudzira kuchinjira ku316 kunyangwe ichidhura zvakapetwa kaviri.304 inobatwa nekuora kana ikashandiswa kana kuchengetwa panze.Kunyangwe iyo nzvimbo yakacheneswa uye passivation layer ikaumbwa, mamiriro ekunze anogona kuita pamusoro, achiparadza passivation layer uye pakupedzisira kukonzera ngura zvakare.
"Kugadzirira kweWelding kwakakosha kune zvikonzero zvakati wandei," anodaro Gabi Miholix, Application Development Specialist, Abrasive Systems Division, 3M Canada, London, Ontario.“Kubvisa ngura, pendi nemabhero kwakakosha pakuita kuti pave nemagetsi.Iyo weld surface inofanirwa kunge isina zvinosvibisa zvinogona kunetesa mubatanidzwa."
Hatelt anowedzera kuti kucheneswa kwenzvimbo kunodiwa, asi pre-weld gadziriro inogonawo kusanganisira chamfering zvinhu kuti ive nechokwadi chekunamatira uye kusimba kweiyo weld.
Paunenge uchipinza simbi isina tsvina, zvakakosha kuti usarudze simbi chaiyo yekuzadza giredhi riri kushandiswa.Simbi isina tsvina inonyanya kunzwisiswa uye inoda kuti welds abvumidzwe kune imwechete mhando yezvinhu.Semuenzaniso, base simbi 316 inoda filler metal 316. Welders haigoni kungoshandisa chero rudzi rwesimbi yekuzadza, giredhi rimwe nerimwe resimbi isina tsvina rinoda kuzadza kwakananga kuti kusungirire zvakanaka.
"Paunenge uchipisa simbi isina tsvina, welder anofanirwa kunyatsotarisa kudziya," akadaro Michael Radaelli, maneja wechigadzirwa weNorton |Saint-Gobain Abrasives, Worcester, Massachusetts."Kune michina yakawanda yakasiyana inogona kushandiswa kuyera tembiricha yeweld uye chikamu sezvo welder ichipisa, nekuti kana mutswe ukabuda musimbi isina tsvina, chikamu chinoparara."
Radaelli akawedzera kuti welder anofanira kuona kuti haagare munzvimbo imwechete kwenguva yakareba.Multi-layer welding inzira yakanaka yekuchengetedza iyo substrate kubva pakupisa.Kwenguva refu welding ye base Stainless simbi inogona kuita kuti iwedzere kupisa uye kutsemuka.
"Welding simbi isina tsvina inogona kutora nguva yakareba, asi zvakare inyanzvi inoda maoko ane hunyanzvi," akadaro Radaelli.
Kugadzirira kwemashure-weld kunoenderana nechigadzirwa chekupedzisira uye kushandiswa kwayo.Mune zvimwe zviitiko, Miholix akatsanangura, iyo weld haisati yaonekwa, saka chete kucheneswa kwemashure-weld kunodiwa, uye chero spatter inooneka inobviswa nekukurumidza.Kana kuti weld ingada kukwenenzverwa kana kucheneswa, asi hapana chakakosha kugadzirira kwepamusoro kunodiwa.Kana kupera kwakanaka kana girazi kuchidikanwa, mamwe matanho epamusoro ekupolisha anogona kudiwa.Zvinongoenderana nekushandisa.
"Chinetso harisi ruvara," Miholic akadaro."Uku kushanduka kwepasi kunoratidza kuti zvimiro zvesimbi zvachinja uye zvino zvinogona kuita oxidize / ngura."
Kusarudza inosiyana yekumhanyisa yekupedzisa chishandiso kunochengetedza nguva nemari uye kubvumira mushandisi kugadzirisa kupedzisa.
Zvakakosha kubvisa ruvara kuitira kuti ngura irege kuvaka nekufamba kwenguva uye kuderedza chimiro chese.Zvakanakawo kubvisa bluing kuti kunyange kunze kweruvara rwepamusoro.
Nzira yekuchenesa inogona kukuvadza nzvimbo, kunyanya kana uchishandisa makemikari akaoma.Kuchenesa kusina kunaka kunogona kudzivirira kuumbwa kwepasi passivation layer.Ichi ndicho chikonzero nyanzvi dzakawanda dzinokurudzira kucheneswa kwemaoko kwezvikamu izvi zvakasungirirwa.
"Nekuchenesa nemaoko, kana iwe usingabvumire oxygen kuti iite nechepamusoro kwemaawa makumi maviri nemana kana makumi mana nemasere, hauna nguva yekugadzira nzvimbo isina kujeka," akadaro Douville.Akatsanangura kuti pasi panoda okisijeni kuti iite nekromium iri mune alloy kuti iite passivation layer.Mune zvimwe zvitoro, itsika kuchenesa, kurongedza zvidimbu, uye nekutumira ipapo ipapo, izvo zvinononotsa nzira uye zvinowedzera njodzi yekuora.
Vagadziri uye welders vanowanzo shandisa zvinhu zvakawanda.Zvisinei, sezvambotaurwa, kushandiswa kwesimbi isina tsvina kunoisa zvimwe zvisingakwanisi.Kutora nguva yekuchenesa chikamu idanho rakanaka rekutanga, asi rakangonaka senharaunda yairi.
Hatelt akati ari kuenderera mberi nekuona mabasa ane utachiona.Chinokosha ndechokubvisa kuvapo kwekabhoni munzvimbo yekushanda yesimbi isina tsvina.Hazvisi zvisizvo zvezvitoro zvinoshandisa simbi kuti zvishandure kune simbi isina tsvina pasina kugadzirira kwakakodzera kwenzvimbo yekushanda yechinhu ichi.Uku kukanganisa, kunyanya kana vasingakwanise kupatsanura zvinhu zviviri izvi kana kutenga yavo seti yezvishandiso.
"Kana uine bhurashi rewaya rekukuya kana kugadzira simbi isina tsvina uye ukaishandisa pacarbon simbi, hauchakwanise kushandisa simbi isina tsvina," akadaro Radaelli.“Mabhurashi aya ave kusvibiswa necarbon uye ngura.Kana mabhurashi akasvibiswa, haagone kucheneswa. ”
Zvitoro zvinofanirwa kushandisa maturusi akasiyana ekugadzira zvinhu, asi zvakare vanofanirwa kunyora maturusi "simbi isina tsvina chete" kudzivirira kusvibiswa kusiri madikanwa, akadaro Hatelt.
Zvitoro zvinofanirwa kufunga zvinhu zvakawanda pakusarudza maturusi ekugadzira maturusi esimbi asina tsvina, anosanganisira sarudzo dzekubvisa kupisa, mhando yemaminerari, kumhanya, uye saizi yezviyo.
"Kusarudza chinopisa chinopisa chakavharwa neabrasive kutanga kwakanaka," akadaro Miholix.“Simbi isina simbi yakaoma zvikuru uye inopa kupisa kwakawanda pakukuya kupfuura simbi yakapfava.Kupisa kunofanira kuenda kune imwe nzvimbo, saka kune chifukidzo chinobvumira kupisa kunoyerera kusvika kumucheto we diski, pane kuti ugare pauri kugaya.panguva iyoyo yakanga yakakwana”.
Sarudzo yeabrasive zvakare inoenderana nekuti iyo yakazara kupera kunofanirwa kutaridzika sei, anowedzera.Zviri muziso reanoona.Alumina zvicherwa muabrasives ndiyo yakanyanya kunyanya kushandiswa mumatanho ekupedzisa.Kuita kuti simbi isina tsvina itaridzike yebhuruu pamusoro, iyo mineral silicon carbide inofanira kushandiswa.Inopinza uye inosiya zvidimbu zvakadzika zvinoratidza chiedza zvakasiyana, zvichiita kuti zvive bhuruu.Kana mushandisi achitsvaga chaiyo kana yakasarudzika pamusoro pekupedzisira, zviri nani kutaura nemutengesi.
"RPM idambudziko guru," akadaro Hatelt.“Maturusi akasiyana anoda maRPM akasiyana uye anowanzo mhanya zvakanyanya.Kushandisa iyo RPM chaiyo inopa zvakanakisa mhedzisiro, zvese maererano nekukasira kunoita basa uye maererano nemhando.Tsvaga kuti ndeipi kupera kwaunoda uye kuti ungaiyera sei."
Douville akawedzera kuti kuisa mari mumaturusi ekupesana ekupesana ndiyo imwe nzira yekugadzirisa matambudziko ekumhanya.Vazhinji vashandisi vanoedza grinder yenguva dzose yekupedzisa, asi inongova nekumhanya kukuru kwekucheka.Kupedzwa kwemaitiro kunoda kuderera.Kusarudza inosiyana yekumhanyisa yekupedzisa chishandiso kunochengetedza nguva nemari uye kubvumira mushandisi kugadzirisa kupedzisa.
Grit inokoshawo pakusarudza abrasive.Mushandi anofanira kutanga neakanakisa grit yekushandisa.
Kutanga ne 60 kana 80 grit (yepakati), mushandisi anogona kusvetukira ku120 grit (yakanaka) uye 220 grit (yakanyanya kunaka) nekukurumidza, ichipa Stainless simbi nzvimbo yechina kupera.
"Zvinogona kunge nhanho nhatu," Radaelli akadaro.“Zvisinei, kana mushandisi ari kushanda nemawelds akakura, haakwanise kutanga aine 60 kana 80 grit uye anogona kusarudza 24 (yakakora kwazvo) kana 36 (yakakoshera) grit.Izvi zvinowedzera rimwe danho uye zvinogona kuva zvakaoma.bvisa makwara akadzika muzvinyorwa zvacho.”
Zvakare, kuwedzera anti-spatter spray kana gel inogona kuve shamwari yepamoyo yewelder, asi inowanzo furatirwa kana welding simbi isina tsvina, Douville anodaro.Zvikamu zvakapwanyiwa zvinofanira kubviswa, izvo zvinogona kukwenya pamusoro, zvinoda mamwe matanho ejecha uye kutora nguva yakawanda.Iyi nhanho inogona kubviswa nyore nyore ne splash guard system.
