摘要： The invention relates to a mould material mixture for producing casting moulds for metal processing, a process for producing casting moulds, casting moulds which can be obtained by the process and their use. The production of the casting moulds is carried out using a refractory base moulding material and a binder based on water glass. 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, with particular preference being given to using synthetic amorphous silicon dioxide. The mould material mixture contains a surface-active material as further significant constituent. The addition of the surface-active material enables the flowability of the mould material mixture to be improved, which makes it possible to produce casting moulds having a very complicated geometry.

摘要： The invention relates to a method for producing cores and molds for the foundry industry, wherein – a flowable fire-resistant primary molding material is provided. An acid is applied to the flowable fire-resistant primary molding material, thus obtaining an acid-coated fire-resistant primary molding material. A binder that can be cured by acid is applied to the acid-coated fire-resistant primary molding material, thus obtaining a fire-resistant primary molding material coated with a binder. The fire-resistant primary molding material coated with a binder is molded into a molded body, and - the molded body is cured, wherein the acid is a mixture of methane sulfonic acid and at least one further sulfur-free acid. The invention further relates to a mold material mixture as it is used in said method. With the method or the mold material mixture, casting molds can be produced having reduced emission of harmful compounds during casting.

摘要： The invention relates to a moulding material mixture for producing casting moulds for machining metal, to a method for producing casting moulds, to casting moulds obtained according to said method and to the use thereof. A fire-resistant moulding base material and a binding agent based on water glass are used in the production of casting moulds. A fraction of the particulate metal oxide is added to the binding agent, said metal oxide being selected from the group comprising silicon dioxide, aluminium oxide, titanium oxide and zinc oxide. Synthetic amorphous silicon dioxide is preferably used. Said moulding material mixture contains a carbohydrate as an additional component. The mechanical resistance of casting moulds and the quality of the surface of the casting piece can be improved by adding carbohydrates.

摘要： The invention relates to a moulding material mixture for producing casting moulds for machining metal, to a method for producing casting moulds, and to casting mouldes obtained according to said method and to the use thereof. A fire-resistant moulding base material and a binding agent based on water glass is used in the production of said casting moulds. A proportion of a particulate metal oxide is added to the binding agent, said metal oxide being selected from the group of silicon dioxide, aluminium oxide, titanium oxide and zinc oxide. Synthetic amorphous silicon dioxide is preferably used. Said moulding material mixture contains a phosphate as an essential component. The addition of phosphate permits the mechanical resistance of casting moulds to be improved under high thermal stress.
