DEVELOPMENTS OF THE INSTITUTE :: QUENCHING SOLIDIFICATION CASTING OF SILUMINSS This technology is based on the quenching solidification casting method. Its essence is that a casting, except an initial rim, solidifies directly in a quenching bath. It makes it possible to increase essentially the crystallization rate of silicon crystals, to change their laminated morphology to the compact one. At the beginning of the process, the casting's initial rim with the thickness of 5-8 mm is formed in a water-cooled metal mold. Then a billet is extracted and placed in the quenching bath, i.e. it solidifies out of the mold. Then a new portion of melt is poured in the mould and the next casting is formed. That is why this technology is in the cyclic nature with high output of the casting process. It is determined only by a time of filling the mould up and duration of forming the billet's initial rim in it. This casting method is easy respondent to mechanization and automation. The experimental casting machine and equipment for development of the silumin production technology using are the now under design.Technical characteristics
Advantages This technology allows production of higher-dispersivity castings from silumins without application of ecologically harmful modifiers, provides obtaining of cast billets with nanostructure eutectic silicon. Application fields The method can be used for:
