A batch of sand (3000 grams for silica, 3500 grams for sintered bauxite and chromite) was placed in the mixer. a resin content of 1.25 based on sand was used at a part i: part ii ratio of 55:45. the part i resin was first added to the sand and mixed for 60 seconds after which the part ii was added and mixed for a further 60 seconds.

The results show that the mechanical properties and microstructures using chromite sand are the best. as the cooling speed increases, the dendrite arm spacing (das) decreases significantly and the mechanical properties are improved, and the elongation is more sensitive to the cooling speed as compared with the tensile strength.

Burnon (also known as burnedonsand or burntonsand) and metal penetration are common surface defects encountered in sand casting of steel. the glossary of foundry terms 1 defines burnedon sand as a misnomer usually indicating metal penetration into sand resulting in a mixture of sand and metal adhering to the surface of a casting.

Can be explained by a more intense heat transfer through the grey iron chill. after six hours of cooling the heat flow at that position equals the heat flow through the chromite core and the grey iron chill, and then it begins to decrease. the tc9 curve, on the other hand, reflects a uniform and steady heat flow with a slight decrease with time.
