Iyo wunvise 'gushora imari muri Inconel', igitekerezo cyihuse akenshi kijyanye nibikorwa bikabije - ibyuma bya turbine, ibyuma byo mu kirere, ibintu byinshi. Ariko hariho icyuho kiri hagati yimpapuro nisuka nyirizina. Amaduka menshi avuga ko ashobora kubikora, ariko gukoresha ayo mavuta ashingiye kuri nikel, cyane cyane nka Inconel 718 cyangwa 625, ntabwo ari ukugira igikonoshwa ceramic hamwe nitanura. Amayeri nyayo ari mumicungire yubushyuhe, igishushanyo mbonera, kandi mvugishije ukuri, kumenya igihe cyo kugenda kure ya geometrie isaba ibibazo gusa. Nabonye imishinga irenze imwe ihagarara kubera ko icyerekezo cyibanze gusa kumanota yibikoresho ku gishushanyo, ntabwo ari uburyo yitwara iyo bishongeshejwe kandi biruka muburyo.
Amavuta ntabwo arinkuru yose
Guhera no gushonga niho utandukanya ibiganiro nakazi. Inconel ifite ingeso mbi yo kubyitwaramo niba ubonye ikirere nabi. Dukoresha itanura ryacu rya vacuum, ariko nubwo bimeze bityo, ibintu bishobora gukurikirana ibibazo. Ntabwo ari ukurinda okiside gusa; nibijyanye no kugenzura igipimo cyo gukonja kuva mubona. Byihuse cyane, kandi ufunga imihangayiko kandi utezimbere micro-porosity izananirwa kugenzura nyuma. Biratinda cyane, kandi ukabona gukura kwinshi kwimbuto, ukica imitungo ya mashini urimo kuyitera kumwanya wambere.
Ndibuka icyiciro cyibintu byubaka muburyo bwa turbine. Icapiro ryahamagariwe gushora imari Inconel 718, ibintu bisanzwe. Ariko uburebure bwurukuta bwari butandukanye. Twasutse, NDT yerekana fagitire isukuye. Ariko, mugihe cyo gukemura ubushyuhe bwo gukemura ubushyuhe, ibice bike byarengeje agakiza. Nyirabayazana? Gukomera kutaringaniye kurema imitekerereze yimbere ubushyuhe buvura bwiyongereye. Amavuta yahuye na spec, ariko inzira ntiyigeze ibazwa imyitwarire yihariye yo kugabanya ubushyuhe. Tugomba gusubira inyuma, tukongera gushushanya Uwiteka gushora imari Gate kugirango habeho gukonjesha kimwe, hanyuma wongereho intambwe yo kugabanya imbaraga mbere yubushyuhe bwuzuye bwo kuvura. Yongeyeho ikiguzi nigihe, ariko byari ibyo cyangwa ibisakuzo.
Aha niho uburambe hamwe numurongo wuzuye. Iduka risuka ibyuma gusa no kohereza ni inshingano. Ukeneye gushinga no gutunganya munsi yinzu, cyangwa byibuze mubufatanye bukomeye. Nakoranye na Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) kuri prototyping mbere. Imiterere yabyo irumvikana - imyaka irenga 30 mugukina no gutunganya, gutunganya ibintu byose kuva ibishishwa kugeza gushora imari hanyuma CNC ikore kubikoresho bimwe. Kuri Inconel, gukomeza ni ngombwa. Ntushobora kugira inzu ya casting ishinja umukanishi ahantu hakomeye, naho umukanishi ashinja umukinnyi mubi. Iyo ari ikintu kimwe, ibitekerezo bisubirwamo birahita. Babona ubuzima bwuzuye, kuva ibishashara kugeza igice cyarangiye, kimenyesha ibyemezo byiza murwego rwo gusuka.
Aho inzira iruma
Inyubako ya Shell niyindi ntambara ituje. Kubyuma bya karubone, sisitemu isanzwe ya stucco irashobora kuguruka. Kuri Inconel, cyane cyane kurukuta ruto cyangwa rugoye imbere yimbere, igikonoshwa gikenera ubushyuhe budasanzwe bwumuriro no gusenyuka. Niba igikonoshwa gikomeye, kibuza guterana mugihe cyo gukonja, biganisha kumarira ashyushye. Niba ifite intege nke cyane, irashobora kuvunika mugihe cyo gukora cyangwa kwisuka ubwayo. Twagerageje kuvanga ibintu bitandukanye-bivanga silika, zircon, alumina - tugerageza gushaka uburinganire bukwiye kumubiri wa Inconel 625. Byasabye inshuro eshatu kugirango ubone igiceri kizarokoka autoclave dewaxing na 1500 ° C + isuka nta gutombora cyangwa gutera ibibazo byo kurangiza hejuru kuruhande.
Ibipimo bifatika nubutaka bwasezeranijwe bwa gushora imari, ariko hamwe na Inconel, kugabanuka ntabwo buri gihe byateganijwe. Amafaranga yatangajwe yo kugabanuka ni intangiriro, ntabwo ari garanti. Ikintu gifatika giterwa nigice cya geometrie, amarembo, nuburyo tuyerekeza muri cluster. Turabungabunga isomero ryibintu bikosora imiryango yacu isanzwe. Imiterere yoroshye ya silindrike irashobora kuba nziza hamwe nigitabo 2.1% kugabanuka kumurongo. Ariko igice gifite imbavu zihuza, nkamazu ya compressor, azakurura ukundi. Ibi twabyize inzira igoye kurutonde rwindege hakiri kare. Twakoresheje itegeko risanzwe ryo kugabanuka, kandi abakinnyi ba nyuma ntibari kwihanganira ibintu bikomeye byo gushyingiranwa. Byabaye ngombwa ko wongera gukoresha ibishashara bipfa, bishyiraho umushinga ibyumweru. Noneho, kubintu byose bishya bigizwe na geometrie, tuzakoresha simulation niba ingano ibyemeza, cyangwa tunasuka prototype imwe yigitambo mumashanyarazi ahendutse mbere yo gupima kugabanuka kwukuri.
Post-casting niho benshi bakeka ko akazi gakomeye kakozwe. Ntabwo aribyo. Imbaraga za Inconel zituruka ku mvura igwa. Kuri 718, bivuze urukurikirane rusobanutse: kuvura igisubizo, kuzimya, imyaka. Igipimo cyo kuzimya ni ngombwa. Niba igice gikonje kuva ubushyuhe bukabije buhoro, ubona imvura ikabije yo gushimangira ibyiciro kumupaka wimbuto, bigatuma igabanuka. Twari dufite icyiciro aho kuzimya imitwaro yaremerewe, ibice byo hagati bikonja buhoro. Batsinze igenzura ryambere ariko birananirana cyane mugupima umunaniro nyuma. Isesengura ryatsinzwe ryerekanye neza kuri microstructure yangiritse kuva kumurongo utangana. Ntabwo byari ibikoresho byananiranye, ntabwo byari ibyuma, ariko ibisubizo byari bimwe - ibisakuzo.
Imashini: Igice cya kabiri cyintambara
Niyo mpamvu moderi ihuriweho na sosiyete nka QSY ifite akamaro. Gutera igice cya Inconel cyuzuye ni kimwe cya kabiri cyakazi. Niba imashini yo hasi ya CNC idahuye kugirango ibintu bikorwe nakazi, uzangiza casting nziza. Inconel irasebanya kandi irakomeye. Iseka ibikoresho bisanzwe. Ukeneye gushiraho cyane, amanota ya karbide yihariye, gukonjesha umuvuduko mwinshi kugirango ucike chip, hamwe nigipimo gito cyibiryo. Intego nukwogosha ibikoresho utaretse ngo ubushyuhe bwiyongere, bikomerera gusa agace ugerageza guca.
Igihe kimwe twakiriye neza Inconel 718 nziza cyane, gusa kugirango imashini yacu ifate imashini eshatu zihenze tugerageza gusya igorofa yoroshye. Ikibazo? Uruhu rwa casting, nubwo rwumvikana neza, rwari rukomeye, rwahinduwe microstructure kuva guhura nigikonoshwa. Ibipimo bisanzwe byo gutunganya, byakoraga imbere mubice, byarakaje cyane kuruhu. Tugomba kongeramo urumuri, intangiriro yo gutambuka hamwe nibintu byihariye kugirango tumenye hejuru yubuso. Nibyiza wiga ukora gusa, cyangwa ukorana numufatanyabikorwa ishami rya CNC rivugana burimunsi nabashinga. Kugenzura urubuga rwabo kuri tsingtaocnc.com, urashobora kubona urutonde rwombi gushora imari na CNC itunganya nikel ishingiye kuri nikel. Ubwo bumenyi bukomatanyije nicyo kibuza ibyo gutungurwa bihenze. Umukanishi azi icyo ategereje kubikorwa byumushinga, kandi uruganda ruzi icyo umukanishi akeneye kugirango akorwe neza.
Ubusugire bwubuso nibyingenzi kubice binaniza umunaniro. Inzira idahwitse irashobora gutangiza micro-crack cyangwa guhangayika bihinduka intangiriro yo gutsindwa. Aha niho intambwe yanyuma yo gutunganya-akenshi gusya cyangwa kubaha hejuru yibintu bikomeye - bihinduka igice cyurwego rwiza. Ntabwo ari ibitekerezo; ni inzira isobanutse. Ubushobozi bwo kugenzura urunigi rwose, kuva icyuma gishongeshejwe kugeza kurangiza, munsi ya sisitemu imwe yubuziranenge, igabanya impinduka kuburyo bugaragara.
Ukuri Kumasoko na Vetting
Noneho, mugihe ushakisha gushora imari Inconel, ni iki ukwiye kureba kirenze agatabo ko kugurisha? Ubwa mbere, baza kubijyanye na filozofiya yo gucunga ubushyuhe. Bakurikiza gusa resept, cyangwa bahindura ibipimo nkubushyuhe bwubushyuhe hamwe nubushyuhe mbere yubushyuhe bushingiye kubice bya geometrie? Icya kabiri, genzura ibikoresho byabo. Kuri icyogajuru cyangwa peteroli & gaze, ukeneye raporo zuzuye zishonga hamwe na chimie cheque. Bashobora gutanga ibyo? Icya gatatu, kandi cyane cyane, reba ubushobozi bwabo nyuma yo gukina. Bashyushya kuvura murugo kugeza byemewe (nka AMS 2774)? Bafite imashini ya CNC yeguriwe amavuta akomeye, cyangwa barayatanga hanze?
Utanga isoko nka QSY, hamwe namateka yabo yimyaka mirongo, mubisanzwe afite sisitemu. Bisobanura ko bishoboka ko bahuye-kandi bagakemura-ibibazo byimikoranire hagati yo gukina no kurangiza. Ntabwo ari iduka ryibishashara gusa; ni uruganda rukora ibintu. Itandukaniro rifite akamaro.
Hanyuma, ushyira mu gaciro kubiciro no kuyobora igihe. Igishoro gikwiye cya Inconel ntabwo gihenze cyangwa cyihuse. Igikoresho cyibishashara kirasobanutse neza. Igikonoshwa ni iminsi-myinshi. Kuvura ubushyuhe nigikorwa gikomeye kigenzurwa. Kandi gutunganya biratinda. Niba amagambo asa nkaho ari meza cyane, birashoboka ko baca inguni - wenda kurwego rwa vacuum mugihe cyo gushonga, cyangwa gusimbuka icyerekezo gikwiye cya HIP (Hot Isostatic Pressing) kugirango ufunge porotike, cyangwa ukoresheje ibikoresho rusange byo gutunganya. Umuntu uwo ari we wese azagaruka guhiga igice muri serivisi. Agaciro ntabwo kari muri pound yicyuma ubona; ni muburyo bugenzurwa, bwanditse, hamwe nibikorwa bihindura icyo cyuma mubice byizewe. Nibyo rwose urimo kwishyura.
