Abstract
What is described is a method of reducing carbon-based emissions and/or carbon-based casting defects during a molding material cycle comprising two or more loops with a smectite-containing clay-containing molding material.
Claims15
A method of reducing carbon-based emissions and/or carbon-based casting defects during a molding material cycle comprising two or more loops with a smectite-containing clay-containing molding material, comprising
- reducing the carbon content in the molding material such that a molding material produced in a later loop has a lower carbon content than a molding material produced in an earlier loop,
- and
- in one or more subsequent loops of said two or more loops of the molding material cycle, adding an additive containing at least one dehydratable inorganic compound that eliminates water at a temperature of 150° C. or more.
