Paunoti '410 simbi isina tsvina', vanhu vazhinji, kunyangwe vamwe vatengi, vanobva vafunga kuti 'isina tsvina, yakanaka kune zvese'. Ndiwo musungo wekutanga. Iyo martensitic, zvinoreva kuti inoomesa nekurapa kwekupisa, kusiyana neakawanda akajairika 304. Iyo magnetic, inogona kuita ngura kana iwe ukaisundira, uye weldability yayo ihurukuro yakasiyana yakasiyana. Ndaona madhirowa akawandisa kwaanofungidzirwa nekuti isarudzo yakachipa isina tsvina, pasina kufunga nezvenzvimbo yebasa kana post-processing inodiwa. Haisi yekudonhedza inotsiva 304 kana 316. Kuita zvisizvo kunoita kuti zvikamu zvikundikane mumhepo inoora kana kuputika panguva yekugadzira. Iyo chaiyo ruzivo haisi mu data sheet's composition chart (11.5-13.5% Cr, handiti?), Asi mukuziva nguva yekuishandisa, maitiro emuchina, uye hutsinye, mabatirwo anoitwa basa racho.
Material Hunhu uye Zvakajairika Misapplication
Chikumbiro chikuru che 410 simbi isina tsvina iko kusanganiswa kwayo kwepakati corrosion resistance, yakanaka ma mechanical properties mushure mekuoma, uye mutengo wakaderera. Iyo 'yepakati' ndiyo kiyi. Mumhepo yakapfava kana yemvura yakachena, zvakanaka. Asi kanda mumakloridhi, maasidhi, kana kungoramba uchinyorova nezvinosvibisa, uye uchaona ngura. Harisi giredhi remugungwa. Ini ndinorangarira batch yezvisungo zvemahombekombe ekushandisa chimiro chakatsanangura 410 kuchengetedza mutengo. Vakaratidza kusviba kwakakosha mukati memwedzi mitanhatu. Mutengi akagumbuka, asi iyo spec yaive isiri iyo kune nharaunda. Taifanira kuchinjira ku316 kuti titsive.
Kwainopenya iri mumaapplication anoda kuomarara uye kupfeka kuramba. Funga pombi shafts, mavharuvhu, cutlery, kana turbine blades. Asi heino kubata: iyo kuoma kunobva mukupisa kurapwa. Mune annealed mamiriro, zviri chaizvo machable. Paunenge uchinge waomesa kuti, taura, HRC 40-45, machining inova basa rehunyanzvi. Unoda maturusi akakodzera, kumhanya, uye mafeed. Kana iwe uchitsvaga chikamu, iwe unofanirwa kuve wakajeka newako mutengesi nezve mamiriro ekupedzisira anodiwa. Iwe unoda here kuti ipiwe annealed kuti iwe uchinje muchina uye kurapwa? Kana kuti unoda kuomeswa zvizere uye pasi? Mukaha wekutaura uyu unokonzeresa kunonotsa kupfuura chero chinhu.
Apa ndipo panodiwa chitoro chemuchina uye chine ruzivo rwakadzama. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakore avo 30 ekugadzira nekugadzira michina, vaiwanzobata kuyerera uku pasina musono. Vaizokanda chikamu vachishandisa goko ravo kana hurongwa hwekudyara, vozoenderera mberi neanealing inodiwa, hutsinye machining, kupisa kupisa (kudzima uye kudzikisira kune kuomarara kwakatsanangurwa), uye kunyatsojeka kwekupedzisira. CNC machining kana kugaya. Kuedza kupatsanura nhanho idzi pakati pevatengesi vakawanda vasina kuenderana nemaitiro echinhu kukumbira dambudziko nekugadzikana kwedimensional kana kupaza.
Kutamba Kwekupisa Kupisa: Kuigadzirisa uye Pazvisina kunaka
Kupisa kurapa 410 inyanzvi yayo. Iyo yakajairwa kutenderera inosanganisira austenitizing kutenderedza 980-1010 ° C, kudzima mafuta, uyezve kupisa. Tembiricha yekudziya inoraira kuoma kwekupedzisira uye kuoma kwechiyero. Kudzikira kupisa (kutenderedza 200-400 ° C) kunopa kuomarara kwepamusoro asi kuderera kwemaitiro kuramba. Enda kumusoro (600-700 ° C), uye unowana kusimba kuri nani asi kuderera kuoma. Iwe unofanirwa kuenzanisa izvi nebasa rechikamu.
Musoro unoshanda kukanganisa. Kunyanya neakaomesesa akakandwa kana akagadzirwa zvikamu, kudzima kunounza kushushikana uye warpage. Kune chikamu chechokwadi senge shaft kana chigaro chevharuvhu, izvi zvinogona kuve nenjodzi. Isu takambove nekumhanyisa kwekudyara kwakakanda mavharuvhu discs akabuda mukupisa kubata nekumhanya kupfuura miganhu inogona kuponeswa. Mhinduro yacho? Dzimwe nguva ndezvekugadzirisa panguva yekudzima, dzimwe nguva ndezvekunetseka-kubvisa nhanho dzepakati panguva yakaoma machining, uye dzimwe nguva unofanirwa kuronga bhajeti yekushanda kwakaoma kwekukuya mushure mekupisa kurapa kudzosa geometry. Haisi kungo'tumira kuti iomese'.
Imwe pfungwa yakavanzika ndeyeyero yekutonhora panguva yekuzvikanda pachayo. For Investment cast zvikamu, iyo as-cast dhizaini inogona kukanganisa kuti yakaenzana inopindura sei kune inotevera kupisa kurapwa. A foundry anonzwisisa izvi anodzora maitiro avo maparamita kuti abudise yakawedzera yunifomu yezviyo chimiro, ichipa zvimwe zvinofanofungidzira kudzika pasi. Izvi hazvisi zvemabhuku; inounganidza ruzivo rwemaitiro kubva mukumhanyisa zviuru zvekupisa nekukanda.
Machining uye Manotsi eKugadzira kubva kuShop Floor
Machining annealed 410 yakatwasuka-inongoita senge simbi yakaderera-alloy. Shandisa zvakanaka rake maturusi, yakanaka inotonhorera, uye iwe wakanaka. Dambudziko riri neyakaomeswa zvinhu kana kunyange iyo 'hafu-yakaoma' mamiriro. Carbide maturusi anofanirwa, uye ceramic kana CBN inogona kudikanwa pakugadzirwa kwepamusoro-vhoriyamu yezvikamu zvakaomarara. Izvo zvinhu zvinowanzoita-kuoma, saka iwe unoda hukasha kucheka zvakakwana kuti upinde pasi peiyo yakaomeswa layer inoumbwa neyakapfuura chishandiso pass. Chiedza, kucheka kucheka kunongopisa chishandiso chako.
Welding inzvimbo inozivikanwa yekurwadza ine 410 simbi isina tsvina. Inoonekwa seyakakwenenzverwa, asi nemapako makuru. Pre-heat (kusvika 200°C) nePost-Weld Heat Treatment (PWHT) inenge nguva dzose inosungirwa kudzivirira kutsemuka kwechando munzvimbo inokonzerwa nekupisa (HAZ). Iyo HAZ inova yakaoma uye ine brittle kana ukangovesa woisiya. Ndakaona maungano akaiswa welding achitsemuka zvinonzwika achitonhodza pauriri hwechitoro. Pakugadzirisa mawelds kana machira, kushandisa 309L filler simbi kwakajairika kuunza mamwe austenite uye kunatsiridza crack resistance. Asi nokutendeseka, kana dhizaini ichisanganisira yakakosha welding ye410, zvakakosha kuti uongorore zvakare sarudzo yezvinhu.
Mashandisiro Echokwadi uye Kutsvaga Kufunga
Saka 410 inonyatsoita zvine musoro kupi? Yakakwana kune yakaoma-inomhanya mechanical zvikamu. Bushings, magiya, uye zvinosungirira muoiri & gasi midziyo (apo nharaunda inodzorwa, kwete musoro wetsime), mapepa emuchina wemichina ari pasi peabrasion, uye michina yekugadzira chikafu uko kunenge kwakapfava asi kuchena kunodiwa. Yayo yakakwirira simba-ku-huremu reshiyo mushure mekurapa zvakare inobatsira.
Paunenge uchitsvaga, hausi kungotenga chinhu, uri kutenga kugona kwekuita. Unoda mutengesi anowana cheni yese. Kutarisa Nhoroondo ye QSY scope - shell mold cast, Investment casting, CNC machining, uye ruzivo nema alloys akakosha-inoratidza kuti akagadzirirwa rudzi urwu rwekugadzirwa kwakabatanidzwa. Kune chikamu chakakosha chinotenderera chakagadzirwa ne410, iwe ungada kuti vaise, kupisa vabate pasi pemamiriro ekudzora, uye vozopedzisa muchina, zvese pasi pedenga rimwe. Izvi zvinodzora zvinoshanduka. Kutumira chivharo kunze kune generic heat treatment uyezve kune imwe chitoro chemuchina kunosuma yakawandisa handoffs uko mataurirwo anogona kuderedzwa.
Mutengo nguva dzose chinhu. 410 inogara panzvimbo inotapira pakati pekabhoni simbi uye yepamusoro nickel austenitic simbi isina tsvina. Asi mutengo wakazara unofanirwa kusanganisira kugadzirisa. Chikamu chinoda machining akaomarara mushure mekuomeswa chichava chinodhura pane chakagadzirirwa kugaya. Mushandi akanaka weinjiniya anozoratidza izvi kutengeserana-offs kutanga.
Pfungwa dzekupedzisira: Nyanzvi, Kwete Generalist
Kupedzisa izvi, 410 simbi isina tsvina chinhu chinobatsira zvikuru, asi chinoda ruremekedzo. Haisi 'stainless simbi' mune colloquial, set-it-and-forget-it sense. Maitiro ayo anoenderana zvakanyanya nenhoroondo yayo yekupisa. Kubudirira nayo kunobva mukuibata sehurongwa: dhizaini yekugadzira, tsanangura iyo inodiwa mamiriro nemazvo, sarudza mucheka wekugadzira neyakasimbiswa metallurgical uye kugadzira chops, uye usambofa wakafungidzira kushora kwayo.
Kutadza kwandakaona kunogara kuchidzokera kune imwe yeaya malink asina simba-mugadziri anoitora se304, mutengi anotenga chete nemutengo wechidimbu-chikamu, kana chitoro chemuchina chisina mapuroteni ekurapa kupisa. Kana cheni ichinge yakasimba, 410 inogadzira yakasimba, inodhura-inoshanda zvikamu zvekuita zvinogara. Ibhiza rekushanda, asi rinoda mubati ane hunyanzvi.
