Uma uzwa I-AMS 5387, into yokuqala evame ukufika engqondweni enye nje yeshidi le-alloy esezingeni eliphezulu lokushisa. Yilokho ugibe ovamile. Eqinisweni, ukubhekana nalokhu kucaciswa kwama-superalloy asekelwe ku-cobalt, ikakhulukazi i-Stellite 6, kuncane mayelana nethebula lokwakheka kwamakhemikhali nokunye okuningi mayelana nomdanso owenziwe ngezandla phakathi kwe-Foundry nesitolo semishini. Yimpahla ethembisa ukuguga okuhle kakhulu nokumelana nokugqwala kuze kufike kulokho, 800°C? Kodwa isithembiso esisephepheni kanye nengxenye esesandleni sakho yimihlaba emibili ehlukene. Ngibone amaphrojekthi amaningi kakhulu ekhubeka ngokwelashwa I-AMS 5387 njengento elula esikhundleni. Akunjalo. Yonke ifilosofi yokwenziwa kufanele ishintshe.
I-Foundry Floor Reality
Ake sikhulume ngohlangothi lokulingisa kuqala. I-AMS 5387 impahla, evame ukuthululwa njenge-Stellite 6, iyisilwane esingasakazwa ngokuhlanzekile. I-cobalt ephezulu kanye nokuqukethwe kwe-chromium kusho ukuthi ijwayele ukwakheka izigaba eziqinile, eziphukayo uma izinga lokupholisa lingalungile nje. Lokhu sikufunde kabuhlungu eminyakeni edlule ngephrojekthi yesihlalo samavalvu. Amaphrinta abiza I-AMS 5387, futhi sithole ingxubevange. Ukukhishwa kwesikhunta segobolondo kokuqala kubonakale kuphelele-ukuphela okuhle kwendawo. Kodwa ngesikhathi sokuhlolwa kwengcindezi, izingxenye eziningana zakha imifantu yezinwele. Akuzona ezisobala, kodwa uhlobo oluthola ngokungena kodayi. Inkinga? Isistimu yethu yokufaka isango nokukhuphuka, ezanele ngokuphelele izinsimbi ezingagqwali ezijwayelekile, ayizange ibale ububanzi bokuqina baleli ngxube. Besiphakela kabi ukuncipha, sidala amaphuzu okucindezeleka angaphakathi.
Kulapho isipiliyoni sesikhathi eside se-Foundry singaxoxiswana khona. Inkampani efana ne-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), neminyaka engamashumi amathathu kugobolondo nokufaka utshalomali, izoba nemingcele yenqubo—isikhunta ukushisa okushisa ngaphambi kokushisa, isivinini sokuthulula, izimiso zokupholisa zangemuva kokusakazwa—sezivele zidayiwe kulawa ma-alloys azwelayo. Akuyona into oyithola ku-spec. Kuwulwazi lwezizwe phansi esitolo. Ngoba I-AMS 5387, umehluko phakathi kokusakazwa komsindo kanye nenqwaba ye-scrap ngokuvamile wehlela endleleni ophatha ngayo iphrofayili eshisayo ukusuka ku-ladle kuya egumbini lokupholisa. Awukwazi ukuvele uphiko.
Obunye ubuqili ubulukhuni be-as-cast. I-AMS 5387 icacisa ububanzi, kodwa i-as-cast state ivame ukuwela ekugcineni okuphezulu. Lokho kuhle kakhulu ekuphikiseni ukugqokwa, kodwa kukhombisa ngokushesha inselelo yesigaba esilandelayo: ukwenza imishini.
