Stressed State of the Shaped Casting under the Impact of Hindered Contraction

Abstract:

The analysis of the bending deformation effect and the central tension arising from hindered contraction of the shaped casting, its stress-strained state, leading to the formation of hot cracks in it has been given in the course of the conducted work. The influence of the main casting parameters and the mold has been studied and their relationship with emerging strains in the molded casting has been determined. The impact on the quantity of the emerging strain of bending stress under hindered contraction has been defined and confirmed by practical calculations. It has been shown that the bending stress is much higher than the emerging tensile stress in the considered conditions. It has been found that the length of the element of hindering and the compliance of a moldable mixture exerts a strong influence on the stress-strained state of the shaped casting.
