MODELING OF POURING L-SHAPED GATING SYSTEM
To date, the hydraulic calculation of gating systems has some difficulties. They are connected, usually with missing data on the value of some of the coefficients of hydraulic resistance typical for foundry. Another problem is the difficulty of determining the nature of the selection of the flow from the collector into the feeder. Investigation of these issues can be made on special stands, where in the laboratory can be observed within a model fluid, determine the rate of interest in cross-section, avoid fluctuations in pressure and the mutual influence of the elements of the gating system. Keywords: L-shaped gating system, sprue, collector, feeder, flow discharge, liquid head. In this paper produced modeling of a stand pouring for the study of the L-shaped gating system with water, using program complexes. The article presents a scheme of the stand, 3D-model, and the results of modeling casting – the velocity distribution in the collector and feeders. The simulation results were compared with calculations obtained coincidence suggests that the numerical simulation can be used for a preliminary assessment of laboratory and other gating systems with the requirement to maintain a constant pressure.
