Brearley akagadzira simbi isina tsvina muna 1916 akawana iyo British patent ndokutanga kugadzira akawanda, kusvika pari zvino, simbi isina tsvina yakawanikwa netsaona mumarara yakave yakakurumbira pasirese, Henry Brearley anozivikanwawo sa "baba vesimbi isina tsvina".Munguva yeHondo Yenyika Yekutanga, pfuti dzeBritish panhandare yehondo dzaigara dzichidzoserwa kumashure nekuti kamuri yaive yakasakara uye isingashandisike.Madhipatimendi ekugadzira zvechiuto akaraira kuvandudzwa kwesimba rakanyanya kupfeka-resisting alloy simbi Breer Li, inyanzvi mukugadzirisa dambudziko rekupfeka kwebore.Brearley nemubatsiri wake vakaunganidza mhando dzakasiyana dzesimbi dzakagadzirwa kumba nekune dzimwe nyika, zvakasiyana-siyana zvakasiyana-siyana zvesimbi yealloy, mumhando dzakasiyana-siyana dzemakina ekuedza kwekuita, uye vozosarudza simbi yakanyatsokodzera kuita pfuti.Rimwe zuva, vakaedza rudzi rwesimbi yemumba ine chromium yakawanda.Mushure mekuedzwa-kudzivisa muedzo, zvakaonekwa kuti iyi alloy yakanga isiri kupfeka, zvichiratidza kuti haigone kushandiswa kugadzira pfuti.Saka vakanyora zvakabuda mukuyedza ndokuzvikanda mukona.Rimwe zuva, mwedzi mishoma gare gare, mubatsiri akamhanyira kuBrearley nesimbi inopenya."Changamire," akadaro, "ndakawana alloy kubva kuna VaMullah pandanga ndichitsvaira imba yekuchengetera zvinhu. Mungada here kuiedza kuti muone kuti inoshanda sei chaizvo!""Kugona!"Brearley akadaro achifara akatarisa simbi yaipenya.
Migumisiro yekuedza inoratidza kuti haityi asidi, alkali, munyu simbi isina tsvina.Simbi isina tsvina yakagadzirwa neGerman mullah muna 1912, asi mullah aisaziva kuti yaive yei.
Brearley akashamisika kuti: "Ko rudzi urwu rwesimbi, isingapfeki asi isingaore, inogona kushandiswa kugadzira tableware, kwete pfuti?"Akati dry dry, akatanga kugadzira Stainless steel fruit fruit banga, forogo, spoon, fruit plate nebanga rekupeta.
Iye zvino kushandiswa kwesimbi isina tsvina kunowedzera uye kuwedzera, kudiwa kuri kuwedzerawo, zvino chinotevera ndechekutaura pamusoro pekugadzirisa uye kushandiswa kwesimbi isina tsvina.
Masimbi ese anopindirana neokisijeni mumhepo kuti agadzire firimu reoxide pamusoro.Nehurombo, iyo iron oxide inoumba pane yakajairwa kabhoni simbi inoramba ichiwedzera oxidize, ichibvumira ngura kuwedzera uye pakupedzisira kuumba maburi.Pamusoro pekabhoni simbi inogona kuchengetedzwa ne electroplating nependi kana oxidization-resistant masimbi akadai zinc, nickel uye chromium, asi, sezvazvinozivikanwa, kudzivirira uku ingori firimu rakatetepa.Kana iyo inodzivirira yakaputsika, simbi iri pasi inotanga kuita ngura.
Inodzivirira kumhepo, chiutsi, mvura uye imwe isina kusimba svikiro uye asidhi, alkali, munyu uye mamwe makemikari ekuora kwepakati corrosion yesimbi.Iyo inozivikanwawo sestainless acid - inodzivirira simbi.Mukushanda kunoshanda, simbi ine simbi isina kusimba inodzivirira inowanzonzi simbi isina tsvina, uye simbi ine kemikari inodzivirirwa inopokana inonzi acid inodzivirira simbi.Nekuda kwemusiyano wekuumbwa kwemakemikari, iyo yekutanga haifanirwe kurwisa kemikari yepakati corrosion, nepo yekupedzisira isingaite ngura.Kudzivirirwa kwekuora kwesimbi isina simbi 2 kunoenderana nealloying zvinhu zviri musimbi.Chromium ndicho chinhu chakakosha kugadzira simbi isina corrosion kuramba.Kana iyo chromium iri musimbi inosvika 12%, chromium neokisijeni mumhepo inoodza zvinoita kuti igadzire firimu reoxide rakatetepa (self-passivation film) pamusoro pesimbi, izvo zvinogona kudzivirira kumwe kuparara kwesimbi matrix.Mukuwedzera kune chromium, inowanzoshandiswa alloy elements uye nickel, molybdenum, titanium, niobium, mhangura, nitrogen, nezvimwewo, kusangana nezvinodiwa zvekushandiswa kwakasiyana-siyana kwekugadzirwa kwesimbi isina tsvina uye kushanda.
Chechipiri, kupatsanurwa kwesimbi isina Stainless simbi kunowanzo kukamurwa kuita:
1. Ferritic simbi isina tsvina.Chromium 12% ~ 30%.Kupokana kwayo necorrosion, kusimba uye weldability kunowedzera nekuwedzera kwechromium yemukati, uye kuramba kwayo kune chloride stress corrosion kuri nani pane mamwe masimbi asina tsvina.
2. Austenitic simbi isina tsvina.Iine zvinopfuura 18% chromium, 8% nickel uye zvishoma molybdenum, titanium, nitrogen nezvimwe zvinhu.Kuita kwakanaka kwakazara, kunogona kuramba kuodzwa kwemhando dzakasiyana dzenhau.
3. Austenitic ferrite duplex simbi isina tsvina.Iyo ine zvakanakira austenitic uye ferritic Stainless simbi, uye ine superplasticity.
4. Martensitic simbi isina tsvina.High simba, asi murombo plasticity uye weldability.
Tatu, maitiro uye kushandiswa kwesimbi isina tsvina.
Ina, Stainless simbi pamusoro muitiro.
Zvishanu, imwe neimwe simbi chigayo kurongedza maitiro uye chikuru kugadzirwa zvigadzirwa.
Zvimwe zvigayo zvesimbi zvemumba: Shandong Taigang, Jiangyin Zhaoshun, Xinghua Dayan, Xi 'an Huaxin, Maodzanyemba, East special simbi, mafekitori madiki aya anonyanya kushandisa marara kugadzira ndiro, kuseri kwekugadzira dhizaini, plate yepasi musiyano, hapana mechanic performance vimbiso, chinhu. zvirimo mufekitari hombe zvinenge zvakangofanana, mutengo wacho wakachipa pane fekitari hombe ine mhando imwe chete.
Inotengeswa kunze kwesimbi zvigayo: Shanghai Krupp, South Africa, North America, Japan, Belgium, Finland, kunze kwenyika bhodhi kugadzira tekinoroji yepamusoro, yakachena uye yakanaka bhodhi pamusoro, chidimbu chechidimbu, mutengo wakakwira kupfuura wepamba yakaenzana modhi.
Nhanhatu, Stainless simbi inotsanangurwa modhi uye saizi: Stainless simbi ndiro ine vhoriyamu uye yepakutanga ndiro vhoriyamu:
1. Roll yakakamurwa kuita inotonhora roll roll uye inopisa roll roll, cut edge roll uye raw edge roll.
2. Ukobvu hwekoiri inotonhora inokungurutswa kazhinji 0.3-3mm, pane 4-6mm ukobvu hwechando chakakungurutswa bepa, yakafara 1m, 1219m, 1.5m, inoratidzwa ne2B.
3. Ukobvu hwevhoriyamu inopisa yakakungurutswa kazhinji 3-14mm, pane 16mm vhoriyamu, yakafara 1250, 1500, 1800, 2000, ine NO.1.
4. Mipumburu ine hupamhi hwe1.5m, 1.8m uye 2.0m inochekwa mitsetse.
5. Upamhi hweburr roll kazhinji 1520, 1530, 1550, 2200 zvichienda zvakadaro hwakafara kupfuura hupamhi hwakajairika.
6. Panyaya yemutengo, iyo modhi yakafanana yekucheka edge roll uye mbishi edge roll inowanzosiyana nezve 300-500 yuan.
7. Ivhu rinogona kugadziriswa maererano nehurefu hwezvinodiwa nevatengi, mushure mokunge muchina wekuvhura unonzi ndiro yakazaruka.Cold rolling general opening 1m*2m, 1219*2438 inonziwo 4*8 feet, hot rolling general opening 1.5m*6m, 1.8m*6m, 2m*6m, maererano nemasaizi aya anonzi standard plate kana fixed size plate.
Iyo ndiro yekutanga inonziwo single sheet rolling:
1. Kukobvu kwebhodhi rekutanga kunowanzo pakati pe4mm-80mm, kune 100mm uye 120mm, ukuru huno hunogona kugadziriswa.
2. Kufara kwe1.5m, 1.8m, 2m, kureba kunodarika 6m.
3. Zvimiro: Indiro yepakutanga ine vhoriyamu yakakura, mari yakakwirira, yakaoma pickling uye kutakura kusina kunaka.
Seven, musiyano wakakora:
1. Nekuda kwekuti simbi yechigayo muchina mukukunguruka, mupumburu unodziya kushoma deformation, zvichikonzera ukobvu hweiyo yakakungurutswa kunze kwendiro kutsauka, kazhinji gobvu pakati uye kutetepa mativi ese.Pakuyera ukobvu hwepuranga, nyika inofanira kuyera chikamu chepakati chemusoro webhodhi.
2. Kushivirira kunowanzo kupatsanurwa kuva kushivirira kukuru uye kushivirira kudiki zvichienderana nemusika uye kudiwa kwevatengi.
Sere, chikamu chega chega simbi isina tsvina:
1. 304, 304L, 304J1, 321, 201, 202 chaiyo giravhiti 7.93.
2. 316, 316L, 309S, 310S chaiyo giravhiti 7.98.
3. Chikamu che400 series i7.75.
