Monel Alloy ibice 400 bitanga imbaraga ntagereranywa kumazi yinyanja, acide, na alkalis-bigatuma iba ingenzi aho gutsindwa atari amahitamo. Ariko guhitamo iburyo monel alloy 400 igice irenze kure imibare yamakuru. Twakoze ibice birenga 12,000 bya Monel 400 kuri pompe hydraulic, imibiri ya valve yo hanze, hamwe na shitingi ya winch yo mu nyanja - kandi kwangwa kwose twabonye guturuka ku kudahuza hagati yo guhangayikishwa no gusaba, geometrie, no gukora metallurgjique - ntabwo biva kuri alloy ubwayo.
Kuki Monel 400 ikora (kandi aho idakora)
Monel 400 ni nikel 67%, umuringa 30%, hamwe nicyuma na manganese. Ibyo bihimbano bitanga imico ibiri idashobora kuganirwaho: ubudahangarwa bwo guterwa na chloride iterwa no gutuza muri pH 2–12. Mubikorwa, ibi bivuze ko inzu ya pompe ya piston iri muruganda ruyungurura imara 3.2 × kurenza 316 ibyuma bitagira umwanda-byemejwe namakuru yacu yo mumezi 18 yo mumashanyarazi yaturutse mubikorwa bitatu byo mu nyanja y'Amajyaruguru. Ariko Monel 400 irananirwa byihuse kubera guhangayika bikabije hejuru ya MPa 450 cyangwa iyo ihuye na acide sulfurique ishyushye. Twigeze gukuraho ibiti 47 bya valve nyuma yo guturika mugihe cya hydrotesting - kubera ko umukiriya yerekanye Monel 400 kumurongo wa serivisi ya 500 ° C H₂SO₄. Amavuta ntiyari yibeshye; i Porogaramu.
Ibipimo bine byo gutoranya byemeza intsinzi
Wibagiwe ibirango rusange "birwanya ruswa". Kwizerwa kwukuri kwisi biterwa nibintu bine bifatanye:
- Kuramo inzira geometrie: Amazu ya Monel yuzuye amazu 400 ahindagurika munsi ya hydraulic. Turasaba inama byibura uburebure bwa mm 4.5 kuri pression> 250 bar - kandi buri gihe tugenzura kugabana umwanya wo kugabanwa ukoresheje FEA mbere yo guca ibyuma.
- Ubuso bwo kurangiza ibisabwa: Ra ≤ 0.8 µm irinda gutangizwa kwamazi mumazi yinyanja adahagaze. Ibisanzwe CNC ihindura amababi Ra 3.2–6.3 µm. Gukora amashanyarazi cyangwa kurangiza neza ntabwo ari ubushake-ni itegeko kubishingwe bya pompe yarengewe.
- Kwinjira muburyo bwo guhuza: Welding Monel 400 isaba kugenzura ubushyuhe bukabije. Dukoresha GTAW hamwe na ERNiCu-7 yuzuza hanyuma dushyushya kugeza kuri 150 ° C - ariko kubice gusa ntibiterwa numunaniro wa cycle. Kubisobanuro bihindagurika cyane nka winch center shaft rollers, twirinda gusudira rwose kandi tugakoresha interineti ihuza na cryo-shrunk Monel 400.
- Uburinganire bwa Microstructure: As-cast Monel 400 ikubiyemo gutandukanya dendritic itumira ruswa ikunda. Igice cyose dutanga gihura nigisubizo kuri 1177 ° C ± 10 ° C muminota 15 kuri santimetero yubugari bwigice - bigenzurwa no gushushanya microhardness ikoresheje ibice.
Igiciro Cyihishe cya "Off-the-Shelf" Monel 400 Ibice
Abaguzi bamwe batanga isoko rusange ya Monel 400, hanyuma bakayikoresha mukarere. Ubwo buryo bukiza 18-22% imbere - ariko byongera ingaruka. Ikibazo cyemeza ibikoresho. Twagerageje ibyiciro 11 byabatanga byanditseho "ASTM B127 Monel 400": bitatu byananiranye kwangirika kwangirika hagati ya ASTM G28A, naho bibiri byagaragaje imbaraga nke z'umusaruro 12-17% kubera akazi gakonje kadatangajwe. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri Monel 400 ingot ikora raporo yuzuye yipimisha-harimo ingano (ASTM E112), ibirimo sulferi (<0.002%), no kugenzura ultrasonic kuri ASTM A388. Nta na kimwe kidasanzwe. Nta bigufi.
Nigute Werekana Monel Yawe 400 Igice Cyiza
Tangira ukora - ntabwo ari ibikoresho. Baza ibi bibazo bitanu mbere yo gutanga igishushanyo:
- Ni ubuhe bushyuhe ntarengwa bwa serivisi * na * ubushyuhe bwo gusiganwa ku magare? (Monel 400 yoroshye hejuru ya 500 ° C - ariko igumana imbaraga kuri -200 ° C.)
- Umuvuduko wamazi> 3 m / s? Urujya n'uruza rwangiza hejuru ya oxyde, bisaba kugenzura Ra kurushaho.
- Igice kizahuza ibyuma bidasa? Irinde guhuza bitaziguye n'ibyuma bya karubone cyangwa aluminium - imigezi ya galvanike yihutisha isenyuka rya Monel 400.
- Ese gutuza kurwego bifite akamaro kuruta imbaraga zuzuye? Monel 400 ifite CTE ya 13.9 µm / m · ° C - hafi yicyuma. Koresha ibyo kugirango ubone inyungu zawe pompe.
- Ese nyuma yo gutunganya ubushyuhe burakenewe? Kugabanya stress kuri 550 ° C bizamura ubuzima bwumunaniro 40% mubice bisubiranamo nkamazu ya silinderi.
Twemeza buri guhamagarwa kwa GD&T kurwanya ubushobozi bwo gukora - ntabwo kwihanganira gusa. Kurugero: kwerekana ± 0.01 mm kwihanganira imyanya kuri 300-mm-diameter ya Monel 400 flange irashobora kugerwaho kumashanyarazi yacu 5-axis. Kugaragaza kwihanganira kimwe kumuyoboro muto ufite uburebure bwa mm-1200 z'uburebure? Ntabwo udafite inkunga ya mandrel-kandi tuzakubwira imbere.
Reba Imbere: Icyitonderwa kirenze ruswa
Kurwanya ruswa ni ameza. Ejo Monel ibice 400 bigomba kandi gucunga kugoreka ubushyuhe, gukomeza imitwaro ya cyclicale, no kwinjiza muburyo budasubirwaho mubikorwa byimpanga. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Turimo gushyira amatangazo ya RFID mumashanyarazi akomeye ya Monel 400 - bituma dushobora kumenya igihe nyacyo cyo kuvura ubushyuhe, raporo za CMM, hamwe nibizamini byapimwe. Turimo kandi twujuje ibyangombwa bya Hybrid casting-gutunganya inzira ya diameter nini ya Monel 400 pompe-kugabanya igihe cyo kuyobora 35% mugihe tunoza guhuza ingano. Intego ntabwo ari ugutanga gusa a monel alloy 400 igice. Nugutanga ibice amateka yimikorere yanditse neza cyane nkibigize imiti.
