Kana iwe ukanzwa 'zvipfeko zvisingabatike', vanhu vazhinji vanobva vangofunga nezvekuoma. Rockwell uyu, Brinell uyo. Ndiyo nhamba yekutanga inobvunzwa nemunhu wese, uye chokwadi, inzvimbo yakanaka yekutanga. Asi kana wanga uri mumutambo uyu kwenguva yakareba zvakakwana, unoziva ndipo panotangira hurukuro chaiyo, kwete kupera. Ndakaona mapurojekiti akawandisa achimira nekuti mumwe munhu akaraira chikamu chakavakirwa chete pakuomarara chiyero kubva kukhathalogi, kungozokundikana mumavhiki mashoma. Chokwadi ndechekuti, kupfeka haasi muvengi mumwechete; musanganiswa weabrasion, kukanganisa, kunamira, uye kazhinji kukora, zvese zvinotamba pamwechete munzvimbo ine hutsinye. Kuibata sedambudziko-mwe-mwe chete ndiyo yakakura, uye inodhura zvakanyanya, kukanganisa kwaunogona kuita.
Iyo Material Maze: Haina Kungove NezveSimbi
Saka unoda chimwe chinhu chakaoma. Mafungiro ako ekutanga angave ekuenda kune yakakwira-chromium simbi yakakandwa kana simbi yekushandisa. Sarudzo dzakanaka, kune mamwe maapplication. Asi ngatiti uri kubata neslurry pombi impeller. Une high-velocity solids inokwesha pamusoro, asiwo mukana wekuratidzwa kwechloride. Simbi yakanyanya-yakaoma inogona kutsemuka pasi pecavitation, kana corrode pamiganhu yezviyo. Apa ndipo panopinda hurukuro yealloy. Takabudirira, uye kukundikana, izvo zvakatisundidzira kune mamwe magadzirirwo anoenderana.
Ndinoyeuka imwe purojekiti yefekitari yesimende, fenicha yakatarisana nekukuvadzwa kwakanyanya neguruva rehupfu. Takaedza yakajairwa NM400 kupfeka ndiro. Zvakaoma sezvipikiri, asi kuzunguzika uye kudiki kukonzeresa kubva kuzvikamu zvakakura zvakatungamira kune kuneta kuparuka panzvimbo dzekukwira. Kuoma kwacho kwakauya pamutengo wekuoma. Iyoyo yakanga iri nguva yokudzidza. Isu takachinjira kune yakaderera kuomarara asi yakakwirira kuomarara simbi ine yakagadziridzwa carbide kugovera mune microstructure. Yakapfeka zvakaenzana uye haina kutsemuka. Mutengo wehupenyu wakadzikira zvakanyanya, kunyangwe iwo ekutanga zvinhu aitaridzika akapfava pabepa.
Ichi ndicho chikonzero makambani anonzwisisa izvi zvechokwadi, senge Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), musangotengesa zvinhu; vanofanira kunzwisisa kukundikana mode. Nekumashure kwavo mukati shell mold casting uye Investment casting, vanogona kutamba nesimbi kubva kumvura. Iyo yakasiyana nhanho yekutonga kana ichienzaniswa nekungogadzira bhaa stock. For zvipfeko zvisingapfeke, maitiro ekukanda pachawo anobvumira kugadzira yakaoma, padhuze-neti-shape geometries inonetsa kugadzira, uye iwe unogona kugadzira mapfekero ekupfeka muchikamu chemucheka chaiwo-sekuisa alloys akawanda asingapfeki panoitika abrasion yakakora.
Iyo Maitiro chikamu cheKuitwa
Kutaura nezve maitiro, iyi ndeimwe nhanho inowanzo furatirwa. Iwe unogona kuve neyakakwana alloy kuumbwa, asi kana kupisa kwekupisa kwakadzimwa, kana kukanda kuchitonhora zvisizvo, unosara uine chikamu chine brittle, chine kushushikana kwemukati, kana zvinhu zvisingawirirane. Ndakaona zvikamu zvinosangana nekemikari yekuongorora yega yega inotadza nguva isati yakwana nekuti iyo post-casting quench yaive nehukasha, ichigadzira micro-cracks.
CNC machining anouya muno, asi kutamba kwakapfava. Machining a hardened kupfeka-inodzivirira chikamu hazvina kufanana nekugadzira simbi yakapfava. Uri kubata nezvinhu zviri kurwisana. Kupfeka kwezvishandiso kunopenga, uye kana ukagadzira kupisa kwakawandisa, unogona kuvharisa iyo yekumusoro layer yawakashanda nesimba kugadzira, uchigadzira ganda rakapfava rinopera nekukurumidza. Unyanzvi huri mukuziva kutevedzana: dzimwe nguva unochina usati wapedza kupisa kupisa, dzimwe nguva mushure, uye nzira dzematurusi nemafudhi zvinoda kuremekedza hunhu hwechinhu. Chitoro chinongogadzira machining akareruka hachizove nekuseta kana kuziva-sei kweizvi. Iyo inyanzvi yehunyanzvi seti, iyo inobatanidza neyokutanga rutivi rwezvinhu.
Kubatanidzwa uku ndiko kunokosha. Kambani inobata zvese kukanda uye kugadzira pasi pedenga rimwe, seQSY (unogona kuona maitiro avo pa https://www.tsingtaocnc.com), ine pundutso. Vanogona kuita sarudzo nekukasika: Kune iyi crusher liner, tinoikanda kune 95% net shape muiyi high-manganese simbi, tobva tangoita mashini ekumisikidza mainterface kudzivirira kukanganisa basa-rakaomarara chimiro. Iro rudzi rwemaitiro ekuyerera kufunga kunochengetedza mutengo uye kuchengetedza kuita. Haisi danho rekugadzira chete; iyo dhizaini-ye-kugadzira uye dhizaini-ye-basa sarudzo.
Apo Special Alloys Isiri Ingori Yakanakisa
Iye zvino, mune imwe nzvimbo yekunze: cobalt uye nickel-based alloys. Mutengo wemutengo unoitisa kuti vanhu vanyemwerere. Hautsananguri izvi zvekunakidzwa. Asi munzvimbo umo kupfeka kwekupisa kwepamusoro kunosangana nekuora - funga zvigaro zvevharuvhu mupetrochemical cracker kana turbine blades munzira inopisa gasi - haisi yekusimudzira; ndivo chete chinhu chichashanda. Kupfeka pano kunowanzo kuve oxidation uye sulfidation pa800 ° C+, yakasanganiswa ne erosive particles.
Takaedza chikamu chesimbi isina tsvina mune yakakwirira-tembiricha ash-kubata system. Zvaitaridzika zvakanaka pazuva rekutanga. Mukati memwedzi, nzvimbo yacho yakanga yave neoxidized uye yakapararira, uye zvinhu zvepasi zvaive zvichibviswa nekukurumidza. Isu takachinjira kune nickel-based alloy ine yakakwira chromium zvemukati. Kupfeka kwakadzikira kuita kukambaira nekuti alloy yakagadzira yakagadzika, inonamira oxide layer yainyatso chengetedza substrate. Chikamu chacho chaipfekwa nokudurura zvishoma nezvishoma iyi nhurikidzwa nokuigadziridza, kwete nokurasikirwa nezvinhu zvine ngozi. Ndihwo huzivi hwakasiyana hwekuramba kupfeka zvachose.
Apa ndipo panowanikwa chiitiko chemuvambi special alloys inokosha. Kukandira zvinhu izvi imhuka yakasiyana. Dzine shrinkage dzakasiyana, fluidity dzakasiyana, uye dzinotyisa kana mhepo iri muchoto ikasadzorwa. A foundry anongoti hongu, tinogona kuzviita pasina rekodhi mureza mutsvuku. Iwe unoda humbowo, senhoroondo yekugadzira zvikamu zvinoshanda zvakasara mumunda. Hazvisi zvekudira simbi; ndezvekudzora kemikari yakaoma kunzwisisa uye maitiro emuviri kuti abudise chimiro che microstructure.
The Fit uye Context
Heino musoro unoshanda usingaite bhurocha: kukwana uye kuisirwa. Unogona kugadzira zvakanakisa pasirese kupfeka-resistant liner, asi kana maburi ekukwira akadzimwa nehafu yemirimita, kana kuti chikamu chidiki chidiki panguva yekupisa kupisa, iyo fitter iri panzvimbo inozofanira kuikuya kuti ikwane. Uri kugaya kure iyo chaiyo yawakabhadhara premium. Ndakazviona zvichiitika. Mamiriro ekushivirira kwechikamu chakapfekwa hachisi chekuita basa; ndezvekuisa. Dzimwe nguva iwe unofanirwa kudoma se-yakakandwa nzvimbo munzvimbo dzisiri dzakakosha uye nzvimbo dzakagadzirwa chete panoitika kusangana. Iyo inodhura-kuita-kuisa katatu katatu.
Imwe pfungwa yezviri kutaurwa: zvinhu zvekusangana. Kusapfeka kwechikamu hakuna zvakunoreva pakuzviparadzanisa nevamwe. Ihurongwa. A super-hard ceramic-coated chute liner inogona kunge yakanakisa kurwisa silica jecha, asi kana ichigara ichirohwa nesando yesimbi manganese, unogona kuwana njodzi chipping. Dzimwe nguva, iwe unoda yakapfava, yakawanda yekupira zvinhu mune chimwe chikamu chegadziriro kuchengetedza yakanyanya kuomarara, inodhura chikamu kuzasi kwerwizi. Izvo ndezvekutonga nzira yekupfeka kuburikidza nemaitiro ese, kwete kungotenga chinhu chakaomesesa chese chikamu.
Aya masisitimu-kufunga ndiwo anopatsanura mupi wezvikamu kubva kumugadziri wemhinduro. Zvinoda kubvunza mibvunzo yakawanda pamberi: Chii chakapfeka? Kupisa kwakadini? Pane kuratidzwa kwemakemikari? Chii chinonzi impact angle? Inoiswa sei? Chii chinotarisirwa hupenyu? Mhinduro dzinotungamira zvese kubva pakusarudza zvinhu kuenda kunzira yekukandira kuenda kune post-kugadzirisa.
Kutarisa Kumashure Kuti Uende Mberi
Mushure memakumi matatu emakore, iwe unoona maitiro. Makambani anogara mundima iyi, seQSY aine makore makumi matatu, haasi kungopona pamutengo. Vakavaka dura rekukundikana kuongorora uye kubudirira nyaya. Vakadzidza, kazhinji nenzira yakaoma, kuti a kupfeka-inodzivirira chikamu ivimbiso yenguva. Haisi nhumbi. Kukosha hakusi mukirogiramu yesimbi; iri mumaawa ekushanda yainoburitsa isati yada kutsiviwa.
Ramangwana, ndinofunga, riri mukubatanidzwa kwakasimba kwekugadzira, sainzi yezvinhu, uye kutonga kwemaitiro. Pamwe ndiyo yakanyanya kuomesesa yekunyepedzera yekupfeka mapatani panguva yedhizaini yedhizaini, kana yepamberi isingaparadze kuyedza kuvimbisa kunzwika kwemukati muzvikamu zvakaoma zvekukanda. Chinangwa chinoramba chiri chimwe chete: kuenzanisa zvinhu zvakakodzera, zvakaumbwa uye zvakabatwa nenzira yakarurama, kune imwe nzvimbo chaiyo yemasimba anoparadza. Ipikicha isingapere, asi ndizvo zvinoita kuti inyatsoshanda. Hazvisi zvekungooma chete. Chero ani anokuudza neimwe nzira pamwe haana kupedza nguva yakakwana pauriri hwekugadzirisa, achitarisa chikamu chakakundikana uye achinetseka kuti chii chaungaedza chinotevera.
