Abstract

Aims To study the technical properties of zircon sand and PEPSET nobake sand

so as to solve the cast problems caused by the quality of sand. Methods The properties of zircon sand and PEPSET nobake sand are tested and the results are analyzed. Results The technical performances such as curing rate

shock thermal expansion

collapsibility

gas evolution of the new-style sand are obtained

which are well suit for making mold. Conclusions The new-style sand can be used to make mold and core mold of the complicated casts

and it will be the new direction of nobake sands.
