摘要： The invention relates to a mold material mixture for producing casting molds for metal processing, a process for producing casting molds, casting molds which can be obtained by the process and their use. The production of the casting molds is carried out using a refractory base molding 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 mold material mixture contains a surface-active material as further significant constituent. The addition of the surface-active material enables the flowability of the mold material mixture to be improved, which makes it possible to produce casting molds having a very complicated geometry.

摘要： The invention relates to a molding mixture for producing casting molds for metalworking, a process for producing casting molds, casting molds obtained by the process and also their use. To produce the casting molds, a refractory mold 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, aluminum oxide, titanium oxide and zinc oxide is added to the binder, particular preference being given to using synthetic amorphous silicon dioxide. The molding mixture contains a phosphate as essential constituent. The use of phosphate can improve the mechanical strength of casting molds at high thermal load.
