Vanhu vazhinji pavanonzwa 'simbi isina tsvina yakarasika yarasirwa wakisi', vanofungidzira chinhu chisina changapomerwa, chinopenya kubva mubhurocha. Ndiyo yekutanga kusanzwisisa. Icho chokwadi chakanyanya kuipa, chakanyanya nuances, uye chinosanganisira kugadzirisa matambudziko sezvazvinoita. Hazvisi zvekungogadzira chimiro; ndezvekutonga zana rinoshanduka kuti uwane chikamu chinoshanda chinosangana nepepa rakazara nenhamba-kusimba kwesimba, kusaita ngura mune imwe nharaunda, kudzvanywa ratings. The 'stainless' chikamu chinenge herring tsvuku; giredhi rinokosha kupfuura mhuri. 304, 316, 17-4PH-imwe neimwe inoita zvakasiyana-siyana paunoidira pa1500 ° C mugoko receramic. Ndipo panotanga basa chairo.
Iyo Shell Game: Zvese zviri muMold
Ngatitaure nezvedeko. Ichi hachisi chiumbwa chepurasita chete. Iyo yakawanda-layer ceramic nhumbi dzokurwa dzakavakwa nekunyudza wakisi mapatani mumaslurries uye stuccos. Huwandu hwemajasi, nguva yekuomeswa pakati pechimwe nechimwe, hunyoro hwemukati - ita chimwe chikanganiso uye goko rinotsemuka panguva yekudonha (kushamisa, kutadza kutadza) kana kuti harina kusimba zvakakwana kuti rive nesimbi yakanyungudutswa, zvichitungamira kune yatinodaidza kuti 'kupererwa'. Ndakaona muti wewakisi wakakwana wepombi wepombi waparara nekuti bhachi rechitatu rakawoma nekukasira muvhiki yakaoma isina mwaka. Iyo goko yaitaridzika zvakanaka, asi yaive nema micro-cracks. Panguva yekudirwa yaiita sesefa. Kurasikirwa zvachose.
Apa ndipo pane ruzivo kubva muchitoro senge Qingdao Qiangsenyuan Technology Co., Ltd.(QSY) zvinoratidza. Neanopfuura makore 30 mukati Investment casting, vakabika ruzivo urwu mumuitiro wavo. Haisi mubhuku rekushandisa; zviri muruzivo rwenyanzvi kuti slurry inodonha sei, kutaridzika kwegoko rekuomesa. Webhusaiti yavo, tsngtaocnc.com, inonyora kukanda kwegoko sechinhu chakakosha chechikonzero. Ndiro danho rekutanga. Unogona kuva nealloy yakanakisa, asi kana goko rako rikatadza, unenge uchingodira simbi inodhura pasi.
Iyo dewaxing process pachayo yakakosha. Vazhinji vanofunga kuti unongonyungudutsa wakisi kunze. Zvitoro zvakawanda zvemhando yepamusoro zvinoshandisa autoclaves kana flash dewaxing ine high-pressure steam. The thermal shock pagoko rakakura. Kana iyo shell system isina kunyatsoenderana nedanho iri, inotyoka. Izvi takazvidzidza kare nemadziro akaoma, matete-madziro. Yakachinjirwa kune imwe refractory zvinhu zvejasi rekutanga, dambudziko rakagadziriswa. Ndidzo diki, zvinhu-level gadziriso inoparadzanisa chikamu chinoshandisika kubva kune zvimedu.
Giredhi Kuzvidya Mwoyo: Kusarudza Zvakakodzera Stainless
Kudoma simbi isina tsvina kwakafanana nekupinda muchitoro chemidziyo wokumbira mudziyo. Hazvina zvazvinoreva pasina mamiriro. Nezvekumisikidza kwemugungwa, 316 ndiyo inosarudzika kune yayo molybdenum-enhanced corrosion resistance. Asi ini ndakave nevatengi vanosimbirira pa316 yemukati, yakaoma application apo 304 ingadai yakakwana uye yakachipa. Unofanira kusundira shure, kudzidzisa.
Kozotiwo kunaya-kuomesa mamakisi se17-4PH. Fantastic kune yakakwirira-simba, yakaoma simbi isina tsvina yakarasika zvikamu zvekukanda wakisi semabhureki emuchadenga. Asi kupisa kwekurapa kutenderera post-casting hakuregereri zvachose. Madhigirii mashoma kubva pane tembiricha yekuchembera, uye hauwane iyo yaunoda RC kuomarara. Chikamu chinotaridzika chakafanana asi chichakundikana mukuedza. Kutaurwa kwaQSY kwekushanda nema alloys akakosha senge nickel-based anondiudza kuti vanowana izvi. Zvinhu izvozvo zvakatonyanya kushatirwa. Nzira yekukanda inongova hafu yekutanga yerwendo; thermal protocol ndiyo yechipiri.
Ndinoyeuka batch yemitumbi yevharuvhu muCF8M (iyo yakakandwa yakaenzana ne316). Vakapasa ese macheki asi vakatadza bvunzo dzakakomba dzegomba remutengi muindasitiri yemakemikari. Nyaya yacho? Delta ferrite zvemukati. Mwero wekutonhodza mugoko wakadzimwa zvishoma, uchishandura microstructure. Isu taifanira kugadzirisa tembiricha yekudira uye kugadzirisa ganda rekudzivirira - tichiwedzera imwe ceramic fiber layer yakatenderedza zvikamu zvinorema - kunonotsa kutonhora. Dambudziko rakagadziriswa, asi zvakatora simbi yekuongorora kuti iwane chikonzero. Chikamu chacho chairatidzika zvakanaka kumaziso.
The Dimensional Tightrope: As-Cast vs. Machined
Imwe yemapoinzi makuru ekutengesa wakisi yakarasika ndeyepedyo-net-shape forming. Izwi rakakosha ndere 'pedyo.' Chero ani anovimbisa ± 0.1mm kushivirira pane ese maficha e-se-akakanda chikamu ari kutambanudza chokwadi. Unofanira kutonga zvinotarisirwa. Shrinkage inofanotaurwa asi haina yunifomu yakakwana. Chimiro chakareba, chakatetepa chinodzikira zvakasiyana pane chivharo chihombe pakukandwa kumwe chete. Iyo pateni inofa account yeizvi, asi pane nguva dzose mutsauko.
Ndicho chikonzero iyo yakazara-sevhisi modhi yemakambani anobatanidza kukanda uye CNC machining zvine musoro. PaQSY, vanonyora ese ari maviri masevhisi epakati. Iwe unokanda chikamu kuti utore iyo yakaoma geometry 90% ipapo, iine rupo stock pane yakakosha mating nzvimbo, tambo, uye chisimbiso zviso. Zvadaro, unoimisa paCNC chigayo kana lathe uye worova iwo chaiwo zviyero. Kuedza kuwana izvo kushivirira zvakananga kubva kuforoma inzira yebenzi uye inodhura zvakanyanya maererano nekushandisa uye kurasikirwa kwegoho.
Isu takamboedza kukanda giya rine anoshanda, se-akakanda mazino kuchengetedza pamutengo wemuchina. Iyo prototype yaive yakanaka, asi mukugadzira, iyo yakawedzera mutsauko muziso rezino pane akawanda ezvikamu zvaisagamuchirwa. Tinodzidzei? Ziva miganhu yegadziriro. Kanda giya risina chinhu, muchina mazino. Synergy pakati pemaitiro maviri aya-Investment casting yekuoma kunzwisisa, CNC yekunyatso-ndiko uko ukoshi hwechokwadi hunosikirwa mainjiniya.
Iwo Akavigwa Mutengo Vatyairi: Kugaya, Kubereka, uye Kupedzisa
Kutora chikamu chewakisi chakarasika hakusi kwehuremu chete. Chikamu chinokwana 1kg chinogona kutanga semuti wewakisi we3kg. Iyo gating uye mumhanyi system, iyo inofambisa simbi, yakakura uye inogurwa uye inodzokororwa. Goho rako (chikamu chapera huremu maringe nekudirwa huremu hwesimbi) chinhu chikuru chinodhura. Iyo inoshanda gating dhizaini, kazhinji inoteedzerwa nesoftware ikozvino, yakakosha. Gedhi risina kugadzirwa rinogona kukonzera mhirizhonga, kupindira kwemhepo, uye shrinkage porosity muchikamu chakakosha chechikamu chako.
Zvadaro pane kupedza. Mushure mekuzunza uye kucheka-cheka, une chikamu chakafukidzwa neceramic shell remnants uye ane rough gedhi stubs. Inoda kupfurwa, kukuya, pamwe kucheneswa kwemakemikari (kunhonga uye passivation yetsvina kudzorera corrosion-resistant oxide layer). Izvi zvinonyanya kushanda uye zvinowanzofuratirwa mukuronga kwekutanga. Chikamu chine migero yakawanda yemukati chinotyisa chekuchenesa. Ndapedza maawa nemapikicha emazino uye majeti emvura anodzvanyirira achiedza kubvisa ceramic yakasanganiswa kubva mugero rekutonhodza. Iye zvino, isu tinogadzira kuchenesa kubva pakutanga.
Iri basa rekupedzisira-danho ndipo panoramba paine zvakawanda zvehunyanzvi. Marobhoti anogaya anogaya akanakisa kune akajairwa maumbirwo, asi yakaoma, organic-shaped valve imba? Izvo zvinowanzoda hunyanzvi hwekukuya neruoko rwakatsiga kusanganisa nzvimbo pasina kugogodza simbi yepasi. Hunyanzvi.
Kana Yaenda Zvakanaka: Kubhadhara
Pasinei nemusoro, kana iwe uchibata yakakwana, yakaoma simbi isina tsvina yakarasika kukanda wakisi chikamu - toti, imwe-chidimbu turbine impeller ine mabladhi akakomberedzwa izvo zvingave zvisingaite muchina kubva mukusimba - zvakakosha. Kutendeseka kwechikamu chisina welds kana majoini, kugona kushandisa yakakwira-inoshanda alloys mune yakaoma mafomu, yakanakisa kupedzwa kwepamusoro iyo inowanzoda kushoma kugadzirira kwekupfekedza.
Inzira inoda kuremekedzwa kwecheni yese, kubva kujekiseni rewakisi kusvika pakuongororwa kwekupedzisira. Iwe haugone kungova metallurgist kana mukomana wekuwana kana machinist. Iwe unofanirwa kunzwisisa kuti nhanho imwe neimwe inotaura sei kune inotevera. Ndiwo fungidziro yandinowana kubva kumaoparesheni akaita seatsanangurwa paari tsngtaocnc.com. Kugara kwavo kwenguva refu kunoratidza kuti vakafamba nematambudziko aya akabatana kubva kune simbi yakakandwa kusvika kune nickel alloys. Hunyanzvi chaihwo hauna kunyorwa sevhisi; idzo dzakaunganidzwa nhare dzekutonga dzakaitwa pamusoro pezviuru zvekudururwa, vachisarudza magadzirirwo emaitiro kune inotevera.
Saka nguva inotevera paunoongorora kukanda, tarisa kupfuura kupenya. Funga nezvegoko rakanga rakaibata, nzira yaidziya yayakatora kuti isimbise, pfuma yasara kuti igadzirwe, uye basa remaoko rakaichenesa. Ndiyo nyaya yechokwadi yechikamu. Zvimwe zvacho ndezvekutengesa chete.
