Uma abantu abaningi bezwa 'ukufakwa kwe-steel investmenting', bafanekisela ingxenye engenasici, enomumo wenetha iphuma esikhunjeni, ilungele ukusebenza. Leyo yinguqulo yencwajana. Iqiniso, leli olifunda ngemva kweminyaka embalwa kanye nemigqomo embalwa, ukuthi umdanso wokuvumelana. Akukhona nje ngokuncibilikisa insimbi bese uyithela egobolondweni le-ceramic. Kumayelana nokulawula igebe phakathi kokuminyana kwethiyori yemodeli yakho ye-CAD kanye neqiniso elingokoqobo lensimbi eqinisayo—ukuncipha, ukuhlanekezela, ukufakwa. Iningi labafikayo, ngisho nabathengi abathile, bacabanga ukuthi inqubo yomlingo yanoma yini eyinkimbinkimbi. Akunjalo. Ithuluzi elinamandla, kodwa kuphela uma uqonda ulimi lwayo.
I-Core Illusion: As-Cast Finish
Masiqonde lokhu kusengaphambili. Igama elithi as-cast liqeda ngo steel utshalomali Casting cishe igama elingelona iqiniso uma ucabanga indawo eyenziwe ngomshini. Okutholayo indawo engcono kakhulu engenzeka ngqo kusuka kusikhunta se-ceramic, esihle kakhulu uma siqhathaniswa nokubunjwa kwesihlabathi, kodwa kuseyindawo ekhonjiwe. Ngomzimba wevalvu esebenza ngogesi, kungase kulunge ezindaweni ezingavali. Ukuze uthole i-aerofoil ye-turbine blade, ibalulekile. Inani lika-Ra lingase libukeke lilihle ephepheni, kodwa udeveli usesimweni sendawo yasendaweni—i-micro-porosity, umphumela omncane wekhasi elolintshi ovela ku-ceramic slurry. Ngibone amaphrojekthi ema ngoba ithimba labaklami lichaze i-Ra e-cast engu-3.2μm kuyo yonke ingxenye, lingaqapheli ukuthi amakhona angaphakathi nama-undercuts ngokwemvelo ahamba kabi kakhulu. Udinga ukuklama ucabanga ngenqubo, ungaphoqi inqubo ukuthi ihambisane nokuhle.
Yilapho ukubambisana nenkampani esunguliwe kuba ubunjiniyela, hhayi nje ukuthenga. Isitolo esifana ne-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), esinamashumi amathathu eminyaka egobolondweni futhi ukutshala imali, uzokutshela lokhu ngokushesha. Sebekubonile konke.
