Gucumura ifu ya metallurgie yuruganda ntabwo arintambwe yanyuma-nigihe cyo gukora-cyangwa kumeneka kubice byubunyangamugayo, guhagarara neza, no gukora igihe kirekire mubikorwa bikabije. Muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twacumuye ibice birenga 12.000 by'amashanyarazi ya cobalt-nikel kuva mu mwaka wa 2018-cyane cyane ibikoresho byo mu rwego rwa AMS 5387 na T800 bigenewe amazu ya pompe hydraulic, intebe za valve, hamwe na shitingi ya shitingi. Ibyo twize ntabwo byari mubitabo. Yagaragaye mu biti by'itanura, gusikana microstructure, no gusesengura impamvu-nyirabayazana iyo ubucucike bwagabanutseho 0.3% kuri 1,185 ° C cyangwa gukura kw'ingano kwatewe no gukonjesha kwa azote.
Kugenzura Umwirondoro Wubushuhe Ntibishobora kuganirwaho-Cyane cyane kuri Superalloys
Kunanirwa kwinshi mu gucumura ifu ya metallurgie yumurongo wuruganda rusubira inyuma yubushyuhe-ntabwo ari ibikoresho byibikoresho. Gutandukana kwa 15 ° C mugihe cyo gufata umwanya uhinduranya gukwirakwiza AMS 5387 icyiciro cyo gukwirakwiza icyiciro gihagije kugirango ugabanye ubuzima bwumunaniro 37% mumazu ya pisitori ya piston. Dukoresha ibice bibiri-bya molybdenum-bishyushya itanura hamwe nigihe-nyacyo cya thermocouple kubitekerezo bitatu bya radiyo kuri buri mutwaro. Ubushishozi bukomeye: igipimo cyo hejuru kiri munsi ya 3 ° C / min munsi ya 600 ° C birinda kwangirika kwangirika; hejuru ya 900 ° C, dufata iminota 45-ntabwo ari 60-kugirango twirinde gukwirakwizwa cyane kwa cobalt mugihe dukomeza ≥98.2%. Ibi ntabwo ari ibitekerezo. Ni umwirondoro watsinze ASTM B243 kwemeza tensile kuri tombora 92 zikurikiranye.
Ikirere cya Atimosifike kigaragaza mu buryo butaziguye Ubusugire bw'Ubuso-na Machinability
Ibirimo hydrogène bifite akamaro kuruta gazi yuzuye. Turakurikirana ingingo ya H₂ ikime ubudahwema - ntabwo twibanze gusa. Umukiriya umwe wa cobalt alloy nozzles yerekanye micro-piting nyuma yo kuvura ubushyuhe. Iperereza ryakozwe ryerekanye ko hydrogène yinjira mu gipimo cya 99,99% - ariko ikime kiri kuri –42 ° C cyerekanye imyuka y’amazi yatumaga imipaka ikungahaye kuri nikel mu gihe cyo gucumura. Igisubizo: wongeyeho umutego wa kirogenike no gukomera kw'ikime kugera kuri 65 ° C. Igisubizo: Ubuso bwubuso (Ra) bwamanutse buva kuri 1.8 µm bugera kuri 0,6 µm mbere yo gutunganya, bigabanya igihe cyizuba cya CNC 22%. Kubyuma hamwe nibikoresho byuma bidafite ingese, duhindukira kuri ammonia yatandukanijwe hamwe <5 ppm O₂ - byagenzuwe buri saha ukoresheje sensor ya zirconia. Nta na kimwe kidasanzwe.
Umutwaro Geometrie nubucucike bwicyatsi bigomba guhuzwa-Ntabwo ari byinshi
Icyatsi kibisi cyinshi cyumvikana neza - kugeza kugoreka gukubise. Dufata icyatsi kibisi kuri 62-65% kubice bishingiye kuri T800 birenga mm 120. Kubera iki? Kuberako kugabanuka kutaringaniye kurwego rugoye-nkurwo mumashanyarazi yimodoka yimashini-itera umuheto wa mm 0,18 muburebure bwa mm 300 niba ubwatsi bwatsi burenze 66%. Igikosorwa cyacu: ibice byo gupakurura ibice hamwe na pin yo gushyigikira. Ibice bito byicara kuri ceramic nkeya; ibibyimbye byibanze kuruhuka rwinshi-silicon karbide padi. Kugabanuka kugabanuka kuva kuri ± 0.32% kugeza kuri 0.07%. Bonus: itanura ryinjira ryiyongereyeho 18% kuko twakuyeho kugorora nyuma ya sinter.
Kugenzura-Igihe-Gukubita Gukubita Inyuma-Igenzura Buri gihe
Twahagaritse kwishingikiriza ku bushakashatsi bwakozwe bushingiye ku cyitegererezo nyuma y’itsinda ry’imibiri ya valve yananiwe kwipimisha hydrostatike ku kabari 410 - nubwo twatsinze igenzura rya CMM. Impamvu yimizi: poritike yimbere hafi ya radiyo y'imbere yabuze ingingo imwe ya Archimedes gupima. Noneho buri kintu cyo gucumura kigaburira amakuru muri sisitemu ya SinterTrack yihariye: thermocouple array log 120 amanota kuri buri mutwaro; ibyuma bitakaza igihombo byerekana binder kurangiza mumasegonda 0.8; kamera ya infragre yerekana ikarita yubuso bwa emissivitifike yerekana ingano ya coescence kare. Imenyesha ritera kwikora-no-gusubiramo niba ikintu icyo ari cyo cyose cyatandukiriye kurenza imipaka yemewe yo kugenzura-ibarwa ku cyiciro cyibikoresho, ntabwo ku itanura. Ibi byagabanije ubufindo budakora kuva kuri 1.4% bugera kuri 0.23% mumezi 18.
Gukwirakwiza ntabwo bijyanye na Parameter imwe-Byerekeranye no Guhuza Ibyemezo
Gucumura ifu ya metallurgie uruganda rwatsinze bivana nuburyo ikirere, ubushyuhe, igihe, hamwe na geometrie ikora - ntabwo uburyo buri wese akora wenyine. Ubushyuhe bwo hejuru bwa 5 ° C butezimbere ubucucike ariko bikarushaho kwiyongera okiside keretse keretse hydrogene isukuye icyarimwe. Gukonjesha byihuse biteza imbere ubukana ariko bigatumira microcrack keretse ubucucike bwicyatsi bugabanutseho gato. Kuri QINGDAO QIANGSENYUAN, dufata gucumura nka sisitemu ifunze-ifunguye: ifu yifu yinjiza (ingano ya D50, ibice bya ogisijeni, umuvuduko ukabije) ihindura neza itanura mbere yo gupakira. Twasangiye iyi logique-ntabwo ari ibisubizo gusa-nabakiriya mugihe cyo gusuzuma GD&T. Kuberako iyo inzu yawe ya pompe igomba kubaho 20.000 cycle kuri 350 bar, gucumura ntabwo ari ugukora. Nukuzuza amasezerano ya metallurgical.
