Abstract

Introduction. The problem of combining continuous monitoring of the main informative process parameters (mass, temperature, melt consumption) and control of the pouring process is relevant for almost all filling devices today.
Problem Statement. The development of pouring accuracy methods, particularly for small-dose pouring is an important task for the foundry industry.
Purpose. The purpose is to study the dependences of the flow characteristics of the magnetodynamic equipment on the supplied voltage in various conditions of its operation.
Materials and Methods. Physical modelling has been applied for the study of dosing accuracy for small doses in the range of 1.5—3 kg.
Results. The coefficient of the numerical dependence of instantaneous mass flow consumption of a modeling fluid in the trough on the instantaneous mass of a modeling fluid in the trough has been established based on experimental studies with the use of a physical model of magnetodynamic device (MDD). The studies of filling doses within the range from 1.5 to 3 kg have shown that this coefficient corresponds to the range of the electromagnet supply voltage from 12.3 to 16.3 V. There have been determined the efficient range of the poured-metalmass to instantaneous-mass-flow-consumption ratio in the course of casting (2.20—2.25) and the corresponding range of the MDD electromagnet supply voltage to minimize the effect of jet pulsations on the dosing accuracy by
reducing their amplitude. The dosing error does not exceed 1.5% by dose weight in the case of pouring small portions (1.5—3 kg).
Conclusions. A new technical solution for MDD with an inclined weighting trough of a conventional design has been developed based on the electromagnetic transfer of a force proportional to the instantaneous melt mass
in the trough. The implementation of this solution makes it possible to reduce the number of strain gauge power sensors for the instantaneous measurement of the melt mass, from four sensors installed under the melting pot of the MDD prototype to one placed directly under the trough.
