Control of the solidification rate of castings from alloy AL9 due to zonal cooling during low-pressure casting
Journal Title: Metallurgical and Mining Industry - Year 2018, Vol 10, Issue 1
Abstract
Purpose. To study the effect of zonal cooling, i.e. various cooling means, accelerating the heat sink to the rate of solidification in local thickenings. Metodology. Applied standard methodology for determining zonal cooling, speed of solidification, the density of the metal. Results. Determined the influence of zone cooling on the rate of solidification of the local thickening, determined by the density of the metal structure depending on the cooling with copper inserts and water. Originality. A further development of representations about the effect of zonal cooling in the casting under low pressure, the decline of defect shrinkage in the thickenings of the casting and reducing the time of exposure of the metal under pressure. Practical value. The use of zonal water-cooling in the casting under low-pressure parts “filter housing” in the mod. U95A has allowed to eliminate the shrinkage in local thickening and reduced the exposure time of the casting under pressure
