The influence of mold humidity and pouring temperature on occurrence of residual stresses in iron castings

During process of formation of castings residual stresses occur. The paper establishes the present day state of knowledge on parameters influencing residual stresses in iron castings, based on writings on this subject. Furthermore, testing examined the influence of parameters mold humidity and pouring temperature on residual stresses. Tests have been carried out on standard grating test piece made of grey cast iron, poured in sand molds. The obtained measurements have been drawn in diagrams and the influence of parameter has been evaluated
