Iyo abantu benshi bumvise 'sisitemu yo guta ibishashara yatakaye', bashushanya inzira itaziguye, hafi yurukundo: gukora icyitegererezo cyibishashara, kubaka igikonoshwa ceramic, gushonga ibishashara, gusuka ibyuma. Ukuri mubidukikije bibyara umusaruro, cyane cyane uburyo bumwe bwo gufata imiti ivanze, ni imishyikirano ihoraho hagati yubumenyi bwibintu, imbaraga zumuriro, hamwe nibikorwa bifatika. Ni sisitemu, ntabwo ari intambwe imwe, kandi niho abantu benshi basobanura ndetse n'abashakashatsi bashya bazamuka. Bibanda kuri casting ubwayo ariko basuzugura urusobe rw'ibinyabuzima - ibishashara, uburyo bwo kurwanya ikirere cyihuta, uburyo bwo gutesha agaciro, umurongo wo kurasa - byerekana neza niba ubona igihangano cyangwa ibisakuzo. Tumaze imyaka ibarirwa muri za mirongo, gloss irashira vuba; igisigaye nukwibanda kumurongo wubwishingizi.
Intego ya sisitemu: Byose bijyanye no kugenzura no gusubiramo
Igitekerezo cya mbere kitari cyo gucukura ni uko gushora imari ari ubuhanzi. Mumuvange mwinshi, amaduka yakazi make, birashoboka. Ariko kuri firime nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), imaze imyaka irenga 30 ikora, ni inzira igenzurwa ninganda. 'Sisitemu' itangira kera mbere yuko ibyuma bisukwa. Turimo kuvuga ibipimo byo gutera ibishashara. Ubushyuhe, igitutu, hamwe no gufata umwanya wo gutera inshusho ibishashara bigira ingaruka itaziguye kandi birangiye. Itandukaniro rya dogere nkeya irashobora gutangiza kugoreka ibintu byoroshye nyuma. Nabonye imishinga yananiwe kubera ko ubushyuhe bwicyumba cyibishashara butajegajega, biganisha ku bunini bwimiterere idahwitse yatumye icyiciro cyo kubaka igikonjo kiba inzozi.
Noneho haza progaramu ya slurry na stucco. Ibi ntabwo ari kwibiza no guswera gusa. Ubukonje bwibibanza byibanze, ifu ya zircon / silika binder igereranya, ubuhehere mucyumba cyo kwibiramo - buri gihinduka ni ipfundo ugomba guhuza. Kuri nikel ishingiye kuri nikel cyangwa cobalt ishingiye kuri superalloys, QSY ikora buri gihe, igikonoshwa gikeneye kwihanganira ubushyuhe bukabije butarinze gukubitwa cyangwa kubyitwaramo nicyuma.
