Wese munhu anotaura nezveInconel 625 senge ibhureti remashiripiti ekuora-kupisa. Ndizvo, kazhinji. Asi kana iwe wakanyatsoigadzira, wakaipinza, kana kukanda kukanda mairi, unoziva mashiripiti anouya nemutero wakakomba. Haisi chete 'super alloy'; kuzvipira.
The Hype vs. The Lathe
Iwe unoona iyo spec sheet: yakanakisa oxidation kuramba kusvika 1800 ° F, simba rakakura, yadda yadda. Chavasina musoro ndechekuti inoshanda sei-inoomesa. Iwe unotora mudziyo wakanaka, unopinza mukucheka Inconel 625, ita kuti chipu chakanaka chiende, uye kamwe kamwe hausisiri kucheka zvakare-uri kungokwiza uye kugadzira kupisa kwakakwana kupfavisa chishandiso chako, kwete chishandiso. Nzvimbo yacho inooma kupfuura pawakatanga. Ndakaona setups yakashanda zvakakwana pa316L ichangoputswa. Unoda michina yakaoma, yakanaka rake geometries, uye tsinga kuti imhanye zvishoma neinorema, inowirirana chikafu. Kuzengurira rufu.
Inotonhorera haisi sarudzo, ine hurongwa. Unoda kudzvanywa kwepamusoro kuti uiendese kumucheto wekucheka kuti utyore chipingamupinyi chekupisa uye kugeza machipisi. Kana machipisi akachekazve, mutambo wapera wekupedzisa uye chishandiso. Ndinoyeuka rimwe basa kwatakanga tichigadzira guru guru revharuvhu kubva ku Inconel 625 casting. Isu takafunga kuti tainge tadaidzira mukati, asi padanho rekupedzisira rinofinha, tambo ine tambo yakaputirwa pabhawa. Yakasiya mucherechedzo paID zvekuti takatozorasa chikamu chacho. A $20,000 chidzidzo mu chip control.
Uye kutsvaga stock kana kukanda nyaya. Haasi ese 625 akasikwa akaenzana. Iyo yakanyunguduka tsika, chimiro chezviyo-inobata machinability zvinoshamisa. A porous casting ichaparadza maturusi nekukurumidza kupfuura iwe unogona kutaura isa giredhi. Iwe unoda mutengesi anonzwisisa izvi kubva kune yekutanga kumusoro, kwete chete imba yekuchengetera ine bar saw.
Welding: Panoitika Chemistry Test
Welding Inconel 625 ishoma nezve kujoinha uye zvakawanda nezve kuchengetedza zvimiro zvayo. Muvengi mukuru kunaya kwecarbide munzvimbo yakakanganiswa nekupisa (HAZ). Iwe unoiwana ichipisa zvakanyanya kwenguva yakareba, uye chromium carbides inoumba pamwe nemiganhu yezviyo. Kamwe kamwe, zvinhu zvako zvisingadzivirirwe nekuora zvine nzira diki yakanaka yekurwisa padivi peiyo weld. Zvinotaridzika zvakanaka, asi zvinotadza kushanda.
Unoda kudzora kwakasimba pakupinza kupisa. Low amperage, stringer beads, mizhinji inomira kuti itonhore. Uye iwe zvachose unofanirwa kushandisa iyo yakakodzera filler-kazhinji 625 filler simbi pachayo kana dzimwe nguva ERNiCrMo-3. Kushandisa Stainless filler nekuti inoshanda kukundikana kwakavimbiswa. Ndakaona mabasa ekugadzirisa padzimba dzepombi apo mumwe munhu akaita izvozvo. Iyo weld yakabata kumanikidza, asi yakatsemuka kubva kune chloride stress corrosion mumwedzi mitanhatu. Iyo post-mortem yakaratidza mutsara wakajeka apo chemistry yakachinja.
Pre and post-weld cleaning ndeyechitendero. Hapana girisi, hapana sarufa, hapana chinhu. Chero kusvibiswa kunopinzwa muweld pool uye kunoita brittle phases. Iro danho rehutsanana rinonzwa kuvhiyiwa.
The Casting Conundrum
Kutora inzwi rekukanda mukati Inconel 625 inyanzvi. Iyo alloy ine chando chakareba, izvo zvinoita kuti ive nyore kune micro-porosity uye inopisa kubvarura kana geji nekusimuka zvisina kukwana. Haugoni kungodira sesimbi yakakandwa. Iyo inowanikwa inoda kudzora tembiricha yekuumbwa, chiyero chekudira, zvese.
Apa ndipo panonyanya kukosha ruzivo pamusoro pemakumi emakore. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakore avo makumi matatu emugoko uye kuisa mari, vangadai vakavaka iyo chaiyo patani ruzivo. Ivo vaizoziva nzira yekumisikidza yakaoma turbine imba muforoma kuderedza shrinkage stress, kana magadzirirwo efeed system kune gobvu flange inoshanduka kuenda kumadziro akatetepa. Irwo ruzivo rwemadzinza rwausingagoni kuwana kubva mubhuku rekushandisa.
Background yavo mu nickel-based alloys uye CNC machining yakakosha. Havasi kungogadzira chimiro; vari kufunga nezvekuti chikamu chekupedzisira chichagadzirwa sei uye chinonamatwa. Vanosiya mari yakakwana pazviso zvakakomba here? Vanoisa mutsara wekuparadzanisa kuti uderedze kupedza basa panzvimbo yekuisa chisimbiso? Iyo yakabatanidzwa pfungwa inochengetedza hupfumi pasi pemvura.
Nguva Yekuishandisa (Uye Nguva Yekufamba)
Saka nemusoro wese uyu, sei uchishandise? Nyore: kana pasina chimwe chinhu chinopona. Nzvimbo dzemvura yegungwa dzine yakakwira chloride. Flue gasi desulfurization masisitimu. High-tembiricha fasteners pachena kune yakavava gasi. Ndiyo inosarudzika yezvikamu zvakakosha, zvisingafambe mune aggressive chem/petrochemical settings.
Asi ini ndakasundira kumashure pane specs kare. Mutengi aida kuzara Inconel 625 manifold for a mild organic acid service pa 300°F. Ndiko kuwandisa. Takamhanyisa ongororo yemutengo wehupenyu tichiienzanisa neyepamusoro-moly duplex isina tsvina. Iyo duplex yakahwina pamutengo wekutanga, mutengo wekugadzira, uye ingadai yakagara makore makumi maviri ehupenyu hwekugadzira. Dzimwe nguva mainjiniya anotsanangura 625 nekuti iri pane rondedzero yezvinhu zvisingadziviriri, kwete nekuti isarudzo yehupfumi. Chikamu chebasa kuziva nguva yekukurudzira danho pasi.
Imwe nguva yekufamba-yekure ndeye apo dhizaini ine makona akapinza kana inoda toni yakaoma, yakadzika machining. Kushushikana kwaunoita kunogona kunge kusina kukodzera. Dzimwe nguva, kugadzira patsva chikamu kuti chive chakanyanya kugadzirwa-chine hushamwari pane kurwisa zvinhu.
Iyo Real-World Supply Chain
Iwe haungohodha Inconel 625. Iwe unokodzera sosi. Zvekukandira, uri kutsvaga chivakwa chinogona kupa zvinhu certs zvinoteedzera kumashure kwekupisa, iine yakazara chemistry uye michina. Iwe unogona kutotsanangura yako wega kupisa kurapwa-protocol-solution annealing pa2150°F ±25°F inoteverwa nekudzima nekukasira ndiyo yakajairwa kunyungudutsa iwo anokuvadza carbides.
Kumudiwa webasa rakazara, iwe unoda mumwe munhu anobata rwendo rwese. Kutarisa paQSY's scope-kubva pakudyara kwekudyara kwe special alloys kune yekupedzisira CNC machining-iyo inobvisa yakawanda yekunongedza zvigunwe. Kana paine chikanganiso chinowanikwa panguva yekugadzira, zviri pavari kuti vazvigadzirise, kwete gakava pakati peiyo foundry nechitoro chemuchina. Kuenderera mberi ikoko kwakakura kune yakaoma, yakakwirira-yakakosha zvikamu.
Nguva dzekutungamira dzakareba. Zvinhu zvakanaka hazvisi kugara pasherufu. Good foundry capacity yakabhukidzwa. Chero ani anovimbisa kukurumidza kuchinja ari kutema makona, anovimbiswa. Ronga kwemwedzi, kwete mavhiki.
Pakupedzisira, Inconel 625 chinhu chinoshamisa chinoda kuremekedzwa. Haisi nhumbi; kudyidzana pakati pemugadziri, metallurgist, muvambi, uye mugadziri wemashini. Ita kuti cheni ikwane, uye unowana chinobuda chinodarika chirimwa chachakaiswa. Miss a link, uye unowana paperweight inodhura zvakanyanya. Musiyano uri mune gritty, unglamorous mashoko ekuti inogadzirwa sei.
