Abstract:

The possibility of production of thin-walled castings made of GX2CrNiMoN25-6-3 cast steel was assessed for the exemplary final casting with variable wall thickness. The assessment both of the solidification process of the GX2CrNiMoN25-6-3 alloy and of the final degree of mould cavity filling was done by means of the NovaFlow&Solid program. The body of the casting with its variable wall thickness, including sections thinner than 1 mm, demanded for the appropriate production technology. There are presented the results of technological tests with respect to the application of the centrifugal casting, which confirm the adopted technology of pattern and mould production. The analyzed technology makes possible the production of casting of high surface quality, while simultaneously the yield is increased, and by the same the unit cost of production is lower as compared with the production method used thus far.
