“…According to Pattnaik (2017), the properties of the ceramic shell, such as increase of the tensile resistance and decrease of the porosity and permeability, can be improved through the addition of natural agents in the sludge that contain the colloidal silica raw material, during the diving stages of the cluster, which decreases repairs on the shell, and avoids cracks caused by it.…”

O objetivo deste estudo é avaliar o potencial de reciclabilidade do resíduo gerado no processo industrial de fundição de precisão. Na metodologia utilizada fez-se a caracterização física, química, mineralógica e térmica (DTA) das matérias primas utilizadas no processo industrial, bem como do resíduo gerado, denominado resíduo de casca cerâmica (RCC). Os resultados obtidos demonstraram que as matérias primas sílicas sofrem transformação de fases. Analisando o resíduo, verificou-se que ele constitui a fase sílica cristalina de quartzo e desta forma, ele deve ser beneficiado de forma a separar os materiais nobres presentes como chamotes e componentes de zircônio. Ainda, deve-se remover a fração de silica cristalina que, se reutilizada, pode conferir fragilidade à casca cerâmica reciclada em função de mudanças abruptas de volume caracterizadas pelos polimorfos da sílica.

“…Especially in aviation, most hot end components such as turbine blade, turbine rotor blisk, impeller, casing have been produced by this process [5][6][7][8]. The traditional investment casting includes wax pattern pressing and assembly, ceramic shell preparation, alloy melt pouring, and post-treatment [9][10][11][12].…”

Titanium alloy intermediate casing is a typical large casting, with many thin-walled and complex structures. It is a high cost and time-consuming process in the trial stage to manufacturing the wax pattern of the intermediate casing by metal mold. Rapid investment casting based on 3D printed patterns is the development direction of casting technology which integrates digitization and intelligence. In this study, selective laser sintering (SLS) technology was used to realize the rapid prototyping of polystyrene pattern in the precision casting of intermediate casing. A numerical simulation method was used to predict the filling process, solidification and casting defects of the intermediate casing. The simulation results show that the gating system for the casting of intermediate casting was reasonable, the number and size of gating risers met the open design requirements, and a sequential solidification of the casting could be realized. The titanium alloy intermediate casing with excellent metallurgical quality and size accuracy CT7 was successfully produced using centrifugal rapid casting technology.
