Wataa teknolojiyada shaqadinta muhiimka ah ee shidka fulhadda?

Shilaynta shalaynta ferric stainless-steel wuxuu ka dhacaa jajab kala duwan oo loo qaybiyaa cutan, ku dhisn, hoos u socodhinta sare iyo siinista awoodda ku taal shalaynta ferric stainless-steel (thickness-ka laga reebo 0.01 ilaa 3mm iyo lebar-ka laga reebo 10 ilaa 2000mm), si ay u adeegsadaan shaqeela "tallaabooyinka sare, muuqaalo gaar ah, iyo awoodda la xidhiidha" saruuraha elektronik, carro, qalab qol, iyo xaqiiqsanaanta daryeelka.

Shilaynta shalaynta ferric stainless-steel

Jajabta saxda waa u farsamayn, talleecadda sare ee qiimaha iyo jajabka sare ee sare. Waa in lagu dooro jajabka raallinaya iyadoo la raacay aragidda shalaynta ferric stainless-steel (sida la xushmada kor iyo xooggadeed)

Socodka shidka istaynjelays dhexdooda si gaar ah ayaa raacaya tashafka "hore siyaasadda → shaqada dhisan → guushitaanka → saafinta salka → kala soocida awoodda". Tashafka kala duwan ayaa xidhiidha goobaha kala duwan. carruur doonayaasha. Tashafka biyahaan waxaa ku jira:

1. Sabaha inta ka hor inta la soo saaro: Dib u dhiska sabaha inta la soo saaro

Maqsushu waa inay ka saartaan dhammaan xadgudubkii korontooyinka iyo inay beddeshaan sifnteedooda si ay kula jawaabayn kala duwanaanshaha inta la soo saaro.

Ka saaritaanka dirqada iyo gacanta

Waxa weyddiiqa: Ka saaritaanka dirqada oo dambe marka la fuluksado iyo daboolka (haddii dirqada la kulmo, buluug ayaan ka soo baxa marka la fuluksado / lacagga)

Tariiqada: Korontooyinka la furay inay ku dhasho ilaah-dheer (sida laatan hidroksaayd) + daawasho, kadibna la washaayo biyaha runta ahna la quraysiiyaa biyaha cad.

Qalbiga biyaha korontooyinka ka dib marka la washo waa inay tahay isku raac (lana qaadin), nafta oo la kulmo waa inay tahay ≤5mg/m².

Sifninta (tulinta)

Wax: Dhegagga "mugdho" (sida mugdhaha geesiga iyo dhexdeeda) ka dib marka la siiyo bantanka si loo hubiyo inay tahay budan (waxaa ku lug leh ≤0.1mm/m);

Hawl-gudbo: Ixtiraam multi-roll (12 ilaa 24 rolls, iyadoo la isticmaalayo rols badan bantankooda yar), taas oo "kaydiyaya" jidh-hun khasabka kala duwanaanshaha kor iyo hoose;

La xusuus: Bantankooda ayaga qalabka (sida 430 hard), wixii siiyaha wixii u dhici doono in lagu dhaqmo in lagu dhaqmo;

2. Jarida hoos u socda: Sii dheer kacidda iyo awoodda sare ee dhulka

Samee "isbedel yar" kuwo horreeyey si loo hubiyo inay dhammaan tahay shaqada ugu dambeeya ee lagu gudbiyey.

Ka saar burr/chamfering

Sababta: Burrs waxay noqon kartaa geesaha ka dib marka la gurguro yahay iyo marka la soo saaro (waxaa ku lug leh ≤0.05mm, waxaa laga yaabaa inay qurdo qaabka lagu gudbiyey);

Jarida: Bantankooda yar, isticmaal "passivation polishing wheels" (flexible grinding), bantankooda weyn, isticmaal "abrasive belt grinding", ama chemical deburring (corrosion by acidic solutions);

Dheerka burr ka noqon mayno 0.01mm, iyo in korni la'aan ha ahaado xagga.

Sii wagar u dhallinyar

Waxgeldan: Baa hidhiyey qaylo dhexdooda ka dib marka loo qariyo, wajigiya jajab yar (sida "warping") si ay u hubiyaan inay tahay buuxda;

Hawl-gelinta: Qiyaasaha siisid (wax gelinta suuksiyada), iyadoo leh saaxijsiga ±0.02mm/m.

Ka saabsan iyo ku sii daaqan

Waxgeldan: Si loo bixiyo shilal metal iyo buuqda polishi ee la socda marxuminta ugu dambeeya;

Tariiq: Isku dayn ultrasonic (loogu talagalay habkab ah) + ku daaqda hawada cimri (jidda 60~80℃, ka hortagga in ay isku daran doonaan oksijin).

3. Tariiqda hoos celinta: Sii wagar fududid iyo shaqsiyaadka

Beddelista xaaladda sare, maxaa yeelay in lagala hadlo talabooyinka alaabta, taas oo lagu qaybinayo "ishu soo saarka" iyo "shaqsiyaadka":

Ishu soo saarka

Siiyeeyo (HL): Isticmaal fadhi tartiiba ah si aad u siiyeysid tokafkaal in lagu sameyo xaraf toosan (habab qaar ka mid ah: 120#, 240#, 400#, yar yar marka weyn, waa fiican), loo isticmaalo bicida iyo panelal kooxankii koronto.

Siiyeeyo mirrarka: Xaqin dherer (dheel) → siiyeeyo fiican (dheel siiyeeya + pashto siiyeeya), xaqin dhererka hooseleinta Ra waxa la dhigi jiray ≤0.02μm (muujiya mirrarkaas), loo isticmaalo xalinta daaweynta iyo qalabka sare ee dekorashen.

Ilayska midhaha: Xaraf midh ah (sida dahab ama udun) lagu sameeyo hooseleinta adhusha vakshumeed (sida PVD), taas oo ah dekorashen iyo ilaaliyaha korroosha, loo isticmaalo qaybta foonka iyo jilbijil.

Calaamadda shaqsi

Calaamadda ilayska: Fadhi ku dhigso goobta isku daynaya chromate si aad u sameyso filmka oksaydh (2 ilaa 5μm dheer), kordhida ilaaliyaha korroosha (tusaale ahaan, tijaabo korroosha 304 fadhi baada ilayska ayaa gaadhiga 500 saa), loo isticmaalo xalinta alaabta koronto.

Cadaadinta dusha: Isticmaal Teflon (PTFE) ama epoxy resin si aad u dhango gacanta sare oo kaalanka iyo xoolin kala duwan, waxaa loo isticmaala non-stick pans iyo bearing gaskets.

Polishing elektaroonik: Elektaroonik u fiirsada, wuxuu saara tiny protrusions ku tiis kaga soo baxday, ka buuxiya roughness (Ra≤0.1μm), sidoo kale wuxuu kala saara korrosion resistance. Waxaa loo isticmaala qaybta la lahaa cunto (sida straws iyo tableware).

4. Jarida optimizasyon: Xulashada ama cadaadinta xaqiiqsanaanta mekhanikaal

Kuwa sidaas darteed inay dooneen awood iyo flexibility, xulashada waxaa la kala saara heat treatment ama mechanical processing:

Annealing treatment

Waaajibaad: Ka saara work hardening (sida kala badan kacaaddimka iyo hoos u dhaca toughness ee strip-ka ka dib marka la stamp-garo), ka dibna dib u noqda hal-abbaarka soft;

Jarida: 300 series stainless steel waxaa la kala duwanaada 1050 ilaa 1100℃ (la socda 30 ilaa 60 daqiiqo), kadibna cooling waaweyn (water quenching), halkaasa kacaaddimkooda ay ku yarataan HV250 ilaa hooseeya HV150.

Isticmaalka: Waxaa loo isticmaalaa qaybood kala duwan in la weynayo mar labaad (sida habayska istaynjanimmo).

Iskushubiddinta

Waxgab: Kor u qaad koronto (sida kuwa ka mid ah qaybood isku-dar), iyo ku darbeysnaya saynaha;

Tibaabka: Istaynjanimmo 400 waxaa guduudhnaa 300 ilaa 500℃ (la socda saacad 1 ilaa 2), kadibna waqti dheer ayaa qalabnaa si loo dhaqmo jiritaanka HV200 ilaa 250, halkaas oo korontiisa la ilaaliyaa.

Isticmaalka: Qaybood istaynjanimmo isku-dar, qalabab.

Iskudhufashada dhulka

Waxgab: Kor u qaad jiritaanka dhulka (sida in la xidho xidhno);

Tibaabka: Shaqsi toosan (5 ilaa 10μm) waxaa la dhafaa dhulka iyadoo loo istaagayo toosin (500 ilaa 550℃), korunta wuxuu gaadhif karin karaa HV800.

Isticmaalka: Furiyo teleskeen, caynado daaqdaqa.
