    摘要： The invention relates to a method for producing lost cores or molded parts for the production of cast parts, in which a basic molding material is mixed with an alkali silicate or water glass binder and a lost core or a molded part for the production of cast parts is formed using a core shooter in a core box, wherein the alkali silicate or water glass binder contains an alkali silicate or water glass solution having a modulus of 1.5 to 3.5 and natural and/or synthetic additives in a proportion of 0.1 to 25% by weight measured with respect to the total amount of binder, with a particle size of less than 5 μm and the natural and/or synthetic additives are at least aluminum silicate, magnesium silicate and sodium aluminum silicate, each having a proportion of 1 to 5% by weight measured with respect to the total amount of binder. The lost core or the other molded part is formed in an unheated core box, and the lost core thus formed or the molded part is cured using hot air.

    摘要： The invention relates to a method for the production of core preforms for foundry in which a) a mixture of inorganic, refractory foundry sand and a water glass-based inorganic binder is produced, b) the mixture is poured into a heated core box c) the water contained in the mixture is withdrawn by a physical method and d) the core preform is taken out of the core box. The process is characterized by the fact that e) the heated core box is subjected to a depression during filling f) the temperature/dwell time is adjusted after the closing of the core box so that a dimensionally stable and good bearing shell is formed on the edge of the preform g) the preform is immediately removed after opening of the core box and, under the effect of microwaves, is subjected to a complete drying.
