Effect of the Sand Mould Additives on Some Mechanical Properties of Carbon Steel Ck45 Casts

Abstract

The research targets study of influence of additives on sand mold’s properties and, consequently, on that of carbon steel CK45 casts produced by three molds. Three materials were selected for addition to sand mix at weight percentages. These are sodium carbonates, glycerin and oat flour. Sand molds of studied properties were produced to get casts from such molds. The required tests were made to find the best additives with respect to properties of cast. ANSYS software is used to demonstrate the stresses distribution of each produced materials. It is shown that the mechanical properties of casts produced is improved highly with sodium carbonates and is less with oat flour and it is seem a few with glycerin additives. It can be concluded that the sodium carbonates let to get the cast produced with highly mechanical properties.
