    摘要： A method for producing cores and foundry moulds.The method is characterized in that foundry sand, a binder, and a low temperature reaction agent are mixed in a controlled atmosphere, and in that the mixture is maintained under these low temperature and controlled atmosphere conditions until it is introduced into the core box, the temperature and atmospheric control are then eliminated and the temperature raised slightly if necessary.
