Abstract:

Purpose: In article were presented assumptions and choose results of investigations connected with material selection and technology production of prototype’s ceramic stirrer with destination to work in environment of liquid metal. In the research work the result of the design, manufacture and technological verification of SiC/C composite stirrer have been presented.Design/methodology/approach: The design of the stirrer (2D and 3D models) and strength tests on the blade and fragment of the composite axle was prepared in the programme Solid Works and the FEM, using COSMOS software. Polymer infiltration and pyrolysis (PIP) technique was used for fabrication SiC/C stirrer. Examination of wettability and suitability of the SiC/C composite for application in a liquid metal with sessile drop wettability was conducted. The surface geometry, conducted using a non-contact optical profilometer, FRT Micro’Prof.Findings: Further laboratory tests of the SiC/C composite stirrer, designed and developed in the Institute of Lightweight Engineering and Polymer Technology at TU Dresden have confirmed rightness of the design, assumptions regarding the thermal, mechanical and chemical resistance of the stirrer.Practical implications: The technological tests have proven a considerable reduction of the turbulence flow, which with an unchanged system of controlling the stirrer ensured stability of the liquid metal whirl and repeatability of the process.Originality/value: The application of this new material will enable not only the expansion of laboratory research, but it may also facilitate the implementation of liquid/phase technologies of obtaining MMC composites for the industry and thus, contribute to increasing the durability of stirrers in comparison with the solutions applied so far.
