Xa usiva 'umvelisi ochanekileyo', yintoni ethi qatha engqondweni? Kwabaninzi, ligama nje eliqhelekileyo lesiseko esenza iinxalenye ezinzima. Leyo yimbono yokuqala ephosakeleyo. Ayikokuntsonkotha nje; imalunga ne-ecosystem yonke yolawulo-ukusuka kwipatheni yepateni yokufuma ukuya kwigophe lokugqibela lonyango lobushushu kwiblade ye-nickel-based alloy turbine blade. Inxalenye 'echanekileyo' ihlala ithengiswe ngokugqithisileyo ngokuthengisa, kodwa ekusebenzeni, kukusila kohlengahlengiso olongezelelweyo kwaye ngamanye amaxesha, izifundo ezibuhlungu kwi-metallurgy.
Undoqo wayo: Inkqubo kunye neSinergy yeMaterial
Ukuphosa okuchanekileyo, kuthi, kuxhomekeke kwintsebenziswano phakathi kwenkqubo kunye nezinto eziphathekayo. Awunakuthatha nje iresiphi yentsimbi engenastainless 316 kwaye ulindele ukuba yenze okufanayo ekubunjweni kweqokobhe njengoko isenza kutyalo-mali. I-thermal dynamics yahlukile. Ndikhumbula iprojekthi kwiminyaka eyadlulayo kwicandelo laselwandle apho sasisebenzisa ibakala elisemgangathweni. Ukunganyangeki kwe-corrosion bekuvaliwe kuba asikhange siphendule ngesantya esicothayo sokupholisa inkqubo yethu yokubumba iqokobhe elichaphazela imvula ye-carbide. Yayilukusilela okuthe kwalungisa kwakhona inkqubo yethu yokuqinisekisa imathiriyeli.
Apha kulapho ubomi obude benkampani buthetha kakhulu. Thatha Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Ngaphezulu kweminyaka engama-30 ekujuleni nasekusebenzeni, elo xesha asilonani nje. Iguqulela kwithala leencwadi elinzulu, eliphantse libe linembile lendlela, yithi, i-alloy esekwe kwi-cobalt eziphatha ngayo ngexesha lenqanaba lokuthotywa utyalo mali umgca ngokuchasene nabo iqokobhe ngundo ukuphosa ukuseta. Unokufumana indlela yabo eneenkcukacha kwiqonga labo https://www.tsingtaocnc.com. Ayisiyonto ikhazimlayo, kodwa ugqaliselo kwiialloyi ezikhethekileyo zikuxelela ukuba kusenokwenzeka ukuba bajongana ne-aerospace okanye ubushushu obuphezulu bezicelo apho isayensi yezinto eziphathekayo ingeyonto icingelwayo.
Ukhetho phakathi kokungunda kweqokobhe kunye nokuphosa utyalo-mali lucingo lwesigwebo sakudala. Ukungunda kwegobolondo, kusetyenziswa isanti egqunywe ngentlaka, kumnandi kubunzima obuphakathi kunye nemitsi emikhulu yentsimbi okanye iinxalenye zentsimbi-cinga izindlu zempompo. Yomelele. Ukuphosa utyalo-mali, indlela elahlekileyo yewax, yeyezinto ezintsonkothileyo: iindonga ezibhityileyo, ukugqiba umgangatho ocolekileyo, ezo geometries ezingenakwenzeka kumatshini kwi-alloys engenanto okanye ekhethekileyo. A umenzi wokuphosa ngokuchanekileyo ixabiso layo ityuwa ayityhala enye phezu kwenye; baxilonga umsebenzi welungu, umthwalo, kunye nokusingqongileyo kuqala.
The Machining Inextricable Link
Akukho kuphosa ngokwenene 'kubume bomnatha' kwizicelo ezibalulekileyo. Nabani na othi utsiba inyani yokugqiba. Yiyo loo nto udibaniso lwe CNC Machining ayixoxisi. I-casting inikeza ifom esondeleyo, kodwa umatshini uqinisekisa ukuchaneka-indawo yokwenene yemingxuma ye-bolt, i-Ra 0.8 ebusweni ebusweni bokutywinwa. Sifunde kwangethuba ukuba ukwahlula abathengisi bokwenza izinto kunye noomatshini bazisa amaphupha amabi wokunyamezelana. Umchwephesha ugxeka ukugqwetheka kwe-caster; uCaster ugxeka umdlalo kamachine.
Ukubona ukuba i-QSY idwelisa oomatshini be-CNC ecaleni kwezinto zabo ezikhethekileyo zokuphosa sisalathisi esiqinileyo. Icebisa ukuba balawule lonke ikhonkco lexabiso. Olu lawulo lubalulekile. Umzekelo, ukwenza intsimbi eqinileyo yokuphosa intsimbi kufuna iindlela ezithile zesixhobo kunye nezinto zokupholisa ukunqanda umsebenzi wokuqinisa umphezulu ngakumbi. Ukuba amaqela okuphosa kunye nawomatshini aphantsi kophahla olunye, anokulungelelanisa umjikelo wokunciphisa uxinzelelo lokuphosa kunye nolandelelwano lomatshini ukunciphisa ukugqwetheka. Ngumdaniso olungelelanisiweyo.
Intloko ebuhlungu apha iyalungisa. Ubamba njani udidi oluntsonkothileyo, olungalinganiyo lomatshini ngaphandle kokwenza uxinzelelo? Sichithe iiveki siyila kwaye silinganisa imihlathi ethambileyo okanye izilungiso zesiko. Ngumsebenzi ongathandekiyo ongazange uvele kwincwadana, kodwa kulapho idabi lokuchaneka kwenxalenye yokugqibela liphumelele okanye lilahlekile. Umenzi oqaqambisa oku kunokwenzeka ukuba ulima umatshini, wongeza umngcipheko.
Apho izinto zingahambi kakuhle khona: Isifundo sokugada kunye nokutyisa
Ukuba bekufuneka ndalatha kwindawo enye eyahlula iivenkile ezifanelekileyo kwezo zikhethekileyo, yisango lokungena kunye noyilo lokunyuka. Bubugcisa obungaphezulu kwenzululwazi, exhaswa yisoftware yokulinganisa ngoku, kodwa isafuna ukuziva. Ekuqaleni kwexesha lam, sasinebhetshi yezibiyeli zentsimbi ezibonisa i-shrinkage porosity kumacandelo ashinyeneyo. Ukulinganisa kujongeka kucocekile, kodwa asikhange sihoye isiphumo soluhlu oluqinileyo lwealloyi. Isango lokungena lalingqongqo kakhulu.
Isisombululo asikokwenza amasango abe makhulu. Yayimalunga nokubeka ngokutsha amasango angaphakathi kunye nokutshintsha uyilo lokunyuka kwentamo ukwenza indlela yokuqinisa engaphezulu. Olu luhlobo lolwazi oluthe cwaka a umenzi wokuphosa ngokuchanekileyo iqokelela kumashumi eminyaka. Uyibona kwiivenkile eziphethe ipotifoliyo yezinto ezibanzi, ezifana nezo zisebenza nge-nickel-based alloys, ezineemfuno ezahlukeneyo zokutya xa kuthelekiswa ne-carbon steel.
Uhlalutyo lokungaphumeleli ngumgodi wegolide. Yonke indawo echithiweyo, umthengi ngamnye ubuyela kwindlela evuzayo efunyenwe phantsi kovavanyo loxinzelelo, ikufundisa ngakumbi malunga nenkqubo yakho kunemitsi eyimpumelelo elikhulu. Into ephambili kukuba nelebhu ye-metallurgical endlini ukwenza icandelo, i-microscopy, kunye nohlalutyo lwe-SEM ukubona i-micro-shrinkage okanye i-inclusion clusters. Ngaphandle kwesakhono sokuxilonga, uyaqikelela nje.
I-Alloy Gambit: Izinto eziZodwa
Ukusebenza kunye ne-alloys ezikhethekileyo ezifana ne-cobalt okanye i-nickel-based based league yiligi eyahlukileyo. Iindleko zezinto eziluhlaza zodwa zenza ukuba yonke into igalele isiganeko esiphezulu. Ayikokunyibilika nokugalela nje; imalunga nolawulo lomoya. Uninzi lwezi alloys, ujonge ukunyibilika kwevacuum kunye nokugalela ukuthintela i-oxidation kunye nokuthathwa kwegesi. Umda wempazamo yincakuba encinci.
Apha kulapho ubunakho obuxeliweyo bomenzi bufuna ukuphononongwa. Ukuthi usebenza ngealloyi ezikhethekileyo kunokuthetha ukuba wenze ulingo olumbalwa lokugalela, okanye oko kunokuthetha ukuba uneVIM ezinikeleyo (iVacuum Induction Melting) eziko kunye nembali yokuvelisa amacandelo abalulekileyo okubhabha. Le yokugqibela ibandakanya iindlela zoqinisekiso olungqongqo. Xa ndijonga ipotifoliyo ebandakanya ezi zixhobo, ngokukhawuleza ndicinga ngeenkqubo ezincedisayo: i-isostatic eshushu yokucinezela (HIP) ukuvala i-voids yangaphakathi, i-furnaces yonyango lobushushu kunye neendawo ezichanekileyo zokushisa.
Intlawulo, nangona kunjalo, ikwintsebenzo. Icandelo le-alloy elisekwe kakuhle kunye ne-nickel-based alloy inokusebenza kwicandelo le-injini yomoya apho amaqondo obushushu anyibilikisa intsimbi eqhelekileyo. Nantso isiphakamiso sexabiso. Kodwa ifuna a umenzi wokuphosa ngokuchanekileyo ukuba yinxalenye ye-metallurgist, inxalenye yenjineli ye-thermal, kunye nenxalenye yenzondelelo yempambano. Izinga le-scrap kweli candelo lixabiso lokwenza ishishini, kwaye libonakala kwixabiso.
UkuJonga okuGqibeleleyo: Unxibelelwano nguKumkani
Bonke ubuchule bobugcisa buthetha kancinci ukuba unxibelelwano kunye nomxhasi luphuka. Ezona projekthi ziphumeleleyo ndibe yinxalenye yazo zibandakanya iinjineli zabathengi kuphononongo lwethu lwenkqubo. Siza kubahamba ngesizathu sokuba sicebise idrafti yotshintsho lwe-engile okanye uhlengahlengiso oluncinci lobunzima bodonga ukuze kugalelwe ngcono. Kwakha ukuthembana.
Le yenye inzuzo echuliweyo yezindlu ezidityanisiweyo njengaleyo ikhankanywe ngaphambili. Xa ukuphosa kunye nomatshini kunye, i-loop yempendulo iqinile. Umchwephesha unokuxelela injineli yokuphosa, Sifumana izixhobo ezigqithisileyo kule flange; singalungisa ubunzima kule ndawo yendawo kwibhetshi elandelayo? Loo ngxoxo iphinda-phindayo, esebenzayo ayinakwenzeka kwikhonkco lonikezelo elidityanisiweyo.
Ngoko ke, xa kuvavanywa a umenzi wokuphosa ngokuchanekileyo, khangela ngaphaya koluhlu lwezixhobo. Khangela izivubeko, izifundo ezifundiweyo, ukukulungela ukucacisa 'isizathu' samacebiso abo. Ukuchaneka kokwenyani akukho nje kwiimicrons zonyamezelo; kukuchaneka kwengcinga kunye namava asetyenziswa kwisigaba ngasinye, ukusuka kumthi we-wax ukuya kwingxelo yokugqibela yeCMM. Yiloo nto eguqula inxalenye yentsimbi ibe yinto ethembekileyo.
