Abstract
To produce high quality castings, there is a need to analyze the variety of casting defects that I the complicated interactions between multiple factors, such as microstructure, tortion, solidification, part geometry and other similar issues concerning
methodology is applied in this work to find optimal conditions for sand casting a :1 part with minimal formation of shrinkage porosity defect. When planning the ltion experiments for this investigation, a number of the key parameters affecting casting practices and corresponding quality of product have been selected.
Impact of gating system type and design,?n the formation of shrinkage porosity in stainless ~s is investigated. This part integrates the professional capabilities of DI8A company engineering research in the field of gating system design and the professional ware which is based on finite element simulation as a tool widely used in modem Further, the effect of geometry of a desired stainless steel cast product on the of formation of shrinkage porosity in casting is explored. The geometric shape of s steel product is interpreted in this study as the aspect ratio of stainless steel product (with to height relations).
An additional parameter investigated is the effect of stainless steel microstructure on the If shrinkage porosity. It is selected for simulation to explore the effect of variation steel microstructure of austenitic stainless steel grade 88304 and microstructure of ferritic stainless steel grade 88430 on the quality of cast product.
optimising stainless steel casting parameters affecting casting practices, the impact
temperature of stainless steel on the fil1abiliy of the green sand mold cavity is he purpose of optimising pouring temperature is to deliver a complete cast product. explains the impact of stainless steel microstructure variations on mold cavity billability at different pouring temperatures.
Those parameters have been studied and their impact on the stainless steel casting quality based mainly on the formation of shrinkage porosity defect is thoroughly. Investigated for best acting practices The results of those simulations have shown that an opportunity exists for steel foundries to extend their current settings of stainless steel casting.
