Process for producing sand mold |
摘要 |
A foundry mold is produced from sand by blending, with one another, sand, a binder comprising a ester cured-phenolic resin, a curing agent comprising an organic ester compound and one or more additives containing therein a metal of the groups IB to VIII, and molding and curing the mixture into a foundry mold. The mixture is useful in a self-curing molding method and a vapour curing molding method, and the resulting mold is thereby provided with an unexpected improved mechanical strength. In particular the invention is advantageously effective with used or reclaimed refractory sand.
