摘要： This invention relates to heat curable foundry binder systems comprising as separate components (a) a caustic solution of an alkali silicate and (b) hydrated aluminum silicate. The solution is mixed with sand to form a foundry mix. The resulting foundry mix is shaped and heated at an elevated temperature to form a cured foundry shape. Heat is applied by warm air, baking in an oven, microwave, or preferably from hot-box equipment.
