Iyo umuntu avuze ibice bya Hastelloy, benshi batekereza kumasasu yubumaji yo kubora. Imibare yamakuru irashimishije, yizewe, ariko niho ikiganiro nyacyo gitangirira, ntabwo kirangirira. Nabonye ibishushanyo byinshi binanirana kuko bafataga Hastelloy C-276 cyangwa C-22 nkibicuruzwa bitagira umwanda. Ntabwo aribyo. Ikinyuranyo hagati yubushobozi bwa alloy hamwe nibikorwa bikora, byizewe niho imirimo nyirizina ibera - mu ruganda no hasi yimashini.
Umukino wa Casting Conundrum: Byose mubigaburo
Gushora imari ni ukujya kuri complexe Ibice bya Hastelloy, cyane cyane uruzitiro ruto, rukomeye dukunze kubona mu kirere cyangwa imiti ya nozzle ikoreshwa. Amavuta menshi ya nikel hamwe na molybdenum abiha iyo myigaragambyo yimigani, ariko kandi bituma inyamaswa itera neza. Urwego rwo gukomera ruragoye. Urabona amarira ashyushye niba sisitemu ya gating na risering itariyo. Ntabwo ari ikintu ukeka; ni imyaka yicyitegererezo.
Ibi twabyize inzira igoye hakiri kare. Igice cyimibiri ya valve kubakiriya, igenewe serivisi ya chloride ikomeye. Porotipire yatsinze PT, yasaga neza. Ariko munsi ya hydro-test, imisatsi mike yateye imbere iratemba. Ikibazo? Micro-shrinkage. Ntibigaragara, ntabwo biri hejuru, ahubwo ni inenge yica. Igisubizo ntabwo cyari ugukoresha ibyuma byiza gusa. Byari bishushanyije imitwe yo kugaburira, ihindura isuka yubushyuhe bwo kugabanuka, ndetse nicyerekezo cyigice mubice byububiko. Ngiyo uruhande rutangaje rwibintu bidasanzwe.
Amaduka azi ibi, nka Ikoranabuhanga rya Qingdao Qiangsenyuan (QSY), ifite iherezo. Hamwe nimyaka mirongo itatu mugikonoshwa no gushora imari, birashoboka ko basutse buri kintu gisanzwe kandi kidasobanutse nikel ishingiye kumavuta. Urwo rwibutso rwinzego zuburyo, tuvuge, Hastelloy X yitwara na Hastelloy B-3 mugihe cyo gukonja ntigiciro. Ntushobora gukuramo ibyo mububiko bwibikoresho.
Imashini: Aho Ingengo yimari ijya gupfa
Niba gukina ari uguhuza ibyuma muburyo, gutunganya ni intambara igenzurwa. Hastelloy akazi-gakomeye. Birakabije. Shyiramo akantu gato cyangwa igipimo cyibiryo byiza, kandi umaze gukora akarere kegeranye kuruta gukata kwawe. Ntabwo ukiri gukata gusa; urimo gusya no kubyara ubushyuhe bwabasazi, bikomeza kwangiza igikoresho kandi bishobora kugira ingaruka kubice bya metallurgie.
Ingamba ziri hasi kandi zitinda. Umuvuduko ukabije wogukonjesha, gushiraho gukomeye, hamwe na premium, ibikoresho byihariye bya geometrike ntibishobora kuganirwaho. Carbide isanzwe, ariko rimwe na rimwe wibiza muri ceramic cyangwa CBN kugirango urangize passes. Igiciro kuri buri gice ntabwo kiri mubintu bifatika; ni mubikoresho byo gukoresha hamwe nigihe cyimashini. Ndibuka umushinga wimpeta nini ya diameter ya Hastelloy C-2000. Igikorwa cyo guhinduranya cyari cyoroshye kugeza dukubise imbere. Gushyiramo ibisanzwe byinjijwe mu minota mike. Twarangije dukoresha igikoresho-cyiza, igikoresho-cyiza kandi twagabanije ibiryo 40%. Yumvaga gahoro gahoro, ariko niyo nzira yonyine yo kubona isuku idafite ibice bisubiramo.
Aha niho ibikoresho byahujwe byerekana agaciro kabo. Isosiyete ikora byombi kandi Imashini ya CNC murugo, kimwe na QSY yavuzwe, irashobora guhindura inzira yose. Barashobora gusiga ibikoresho byo gutunganya ibintu, bakamenya neza ibikoresho ishami ryabo rya CNC bakeneye kugirango basukure uruhu kandi bihangane. Ikuraho umukino wamakosa hagati ya casting zitandukanye hamwe nabacuruzi bakora imashini.
Umwihariko muri Alloys idasanzwe
Abakiriya akenshi baza bafite icyifuzo cya Hastelloy batagaragaje amanota. Ibyo ni nko gusaba ibyuma. Guhitamo hagati ya B-2 yo kugabanya aside, C-276 kuri okiside ivanze, cyangwa G-30 kubidukikije bya fosifori ni ngombwa. Nibisubizo byimiti. Ariko hariho urundi rwego: guhimba. C-276 ni ifarashi ikoreramo kubwimpamvu - birasa cyane gusudira kandi bihamye murwego runini. B-2 izwi cyane mugihe cyo gusudira niba idakozwe neza.
Noneho hariho amasoko y'ibikoresho ubwabyo. Impamyabumenyi y'urusyo ni ngombwa, ariko gukurikirana ni umwami. Kubice byingenzi bya serivisi, ugomba kumenya umubare wubushyuhe, isesengura ryimiti, kandi nibyiza, ufite ibizamini byo gupima ubushyuhe bumwe kugirango ubone ibyangombwa. Ibi ntibishobora kuganirwaho mu nganda nka peteroli yo hanze na gaze cyangwa imiti.
Ubushobozi bwo gutangiza no kugenzura ibyo bidasanzwe bivanze nubushobozi bwibanze. Umuyoboro wabatanga kandi kwizerwa hamwe ninganda zikomeye. Iyo isosiyete ikora urutonde nikel nk'umwihariko, bivuze ko bafite urwego rwo gutanga no kugenzura bahamagaye. Ntabwo ari ukugira urutonde rwimigabane gusa; ni ukugira imiyoboro yizewe.
Iyo Ibyiza Bihagije Atari: Igenzura rya Gauntlet
Kurangiza igice nikintu kimwe. Kugaragaza ko bikwiranye na serivisi nibindi. Kuri Ibice bya Hastelloy, kugaragara no kugenzura ni igikorwa cyo gufungura gusa. Kwipimisha irangi ryinjira (PT) nibisanzwe kubutunenge. Ariko kubikorwa byingenzi, urareba radiografiya yuzuye (RT) kugirango uhige ibintu byimbere cyangwa kugabanuka, hamwe na ultrasonic test (UT) kugirango uhuze ubunyangamugayo kumateraniro yasuditswe.
Ikizamini nyacyo, mubisanzwe, ni ikizamini cya ruswa. Uburyo bwa ASTM G28 Uburyo bwo kwibasirwa nindangakamere buramenyerewe kumanota menshi ya Hastelloy kugirango barebe niba bakangurira gusudira cyangwa kuvura ubushyuhe budakwiye. Ibi ntabwo byihuse. Harimo guteka icyitegererezo mumashanyarazi ya sulfate-sulfurike ferricike mumasaha 24, hanyuma gupima ibiro. Nibizamini byangiza, ukeneye rero coupons zabatangabuhamya kuva murwego rumwe. Iyi ntambwe itandukanya abakora ibice nabatanga igice.
Gucunga neza ubuziranenge busaba sisitemu. Nimpapuro, kalibibasi, abagenzuzi bemewe, numuco utagabanya inguni. Isosiyete imaze imyaka 30 muri uyu mwanya yarokotse kuko bubatse sisitemu. Urubuga rwabo rushobora kuvuga gusa gutunganya, ariko ibicuruzwa nyabyo nibipapuro byemeza bizana igice.
Kwishyira ukizana
None, ibi byose bivuze iki kubantu bashakisha ibyo bice? Ubwa mbere, wimuke urenze urwego rwibikoresho. Kugaragaza ibidukikije - ubushyuhe, itangazamakuru, kwibanda, imikazo. Icya kabiri, shyira imbere ubushobozi bwibikorwa kuruta igiciro. Amagambo ahendutse ya casting cyangwa gutunganya ni amakosa ahenze cyane. Baza ibyababayeho byihariye hamwe n amanota wahisemo, saba kubona amasomo asa cyangwa usure ikigo.
Shakisha guhuza. Utanga ibicuruzwa bigenzura urugendo kuva mubyuma bishongeshejwe kugeza birangiye, byagenzuwe igice, nkibifatanye gushora imari n'ubushobozi bwa CNC, mubisanzwe bifite amanota make yo gutsindwa. Bafite urunigi rwose. Hanyuma, wubahe ubuhanga. Amaduka meza akemura ibibazo utari uzi ko ufite. Bazabaza igishushanyo kirambuye gitera guhangayikishwa niyi mavuta, cyangwa bagatanga impinduka nkeya ya radiyo kugirango batezimbere.
Amaherezo, gutsinda Ibice bya Hastelloy ntibigurwa mu gipangu. Nibisubizo byubufatanye hagati yubushakashatsi bwamenyeshejwe hamwe ninganda zimenyerewe, aho ibintu byamamare byibintu byahinduwe mu budahemuka mubice bidahuye gusa, ariko bikomeza kubaho kwisi. Ngiyo itandukaniro riri hagati yigice cyakozwe na Hastelloy nigice gikora nkacyo.
