The method is intended for the manufacture of casting molds and cores from quartz sand, which is clad with dry liquid glass. The curing of such sand is carried out by microwave radiation in water vapor. The duration of the structuring of such a mixtu

Steam-microwave structured sand-sodium-silicate mixtures highest technological properties have been obtained under conditions if they are initially in free-flowing state, used sand is mainly fractions of 0, 16 ... 0, 20 mm and, after cladding with so

The use of quartz sand conglomerates with liquid glass makes it possible to use the same mixture both for the working cavity of the casting mold and for the elements of the gating system that feed the casting. That is, conglomerates with dimensions o

One of the reasons restraining the use of microwave radiation in the foundry is the uneven heating of the processed solids and molding sand. An urgent task is to assess the type of radiation power distribution in the chamber of a microwave oven. In t

The nature of the clay, its content in the moldable mixture, as well as the method of preparing water and clay before molding, have a decisive influence on the strength and shedding of low-temperature forms. Mixtures of sand with 5% boiled water and
