摘要： The invention relates to a moulding mixture for producing casting moulds for metalworking, a process for producing casting moulds, casting moulds obtained by the process and also their use. To produce the casting moulds, a refractory mould raw material and a binder based on water glass are used. A proportion of a particulate metal oxide selected from the group consisting of silicon dioxide, aluminium oxide, titanium oxide and zinc oxide is added to the binder. Particular preference is given to using synthetic amorphous silicon dioxide as metal oxide.

摘要： The invention relates to an exothermic molding material mixture for producing feeders for casting aluminum, comprising at least: - a fireproof base molding material; - a binder; - a proportion of an oxidizable metal of from 5 to 18% by weight relative to the molding material mixture; - an oxidizing agent at a proportion of 10 to 50% by weight relative to the quantity of oxidizing agent required for completely oxidizing the oxidizable metal; and - an igniter for oxidizing the oxidizable metal at a proportion of 15 to 50% by weight relative to the quantity of the oxidizable metal. A feeder made of the exothermic molding material mixture ignites reliably, even at low temperatures, and is characterized by low heat emission. It is therefore particularly suitable for casting aluminum.
