Abstract

A series of experiments and inspection for the using CaCl2 as a kind of hardening agent have been made in this paper through orthogonal experiments and regression analysis. Subsquently with the optimum condition

comparing experments with NH4C1 are made in production field. Results show that

not only the green bond and high temperature bond of the shell mould are higher than that of NH4C1

but also some of the shortcomings in using NH4C1 are overcomed. Meanwhile

the surface quality of the castings can be perfectly compared with.
