Description
The processes make it possible to increase productivity of casting of ingots 2÷5 fold and to refine the ingot microstructure 4÷10 fold without application of ecologically unsafe impurity modifiers. A high crystallization rate allows ingots with silicon crystals measuring up to 200 nanometers to be produced. The processes are used for production of ingots with high mechanical and antifriction properties.
Manufacturing processes are based on casting in a jet crystallizer, application of a device with the submerged jet system of secondary cooling, use of a quench hardening casting method.
Operation of the jet crystallizer and the device with the submerged jet secondary cooling system is based on submerged jet cooling of a crystallizer jacket and an ingot, which is uniform throughout height and perimeter. Coolant jets hit a cooling area perpendicularly or at a certain angle and considerably reduce a width of a thermal boundary layer thus increasing a heat-transfer factor and cooling ability of the submerged jet cooling process. Uniformity of cooling of the crystallizer jacket and the ingot increases the equipment durability, stability of the casting process, and ingot quality. Resulting aluminum-silicon alloy billets with nanostructured eutectic silicon have the inverted microstructure with high ductility and friction wear resistance.
Advantages and Innovations
These alloys are antifriction, wrought and have high mechanical properties.
