Application of a complete factorial experiment to optimize the filling factor and charge density of the self-shielding flux-cored wire
The necessity to study such characteristics of self-shielding flux-cored wire as the filling rate (CWF) and core filler density (rсf) is grounded. The influence of the exothermic addition content, exothermic addition components ratio, graphite content on the filling rate (CWF) and filler density (rсf) was studied using Fractional Factorial Design, the mathematical models are built. It is shown that the content of exothermic addition (CEA) and graphite (Сgraphite) in the charge has the greatest influence on the filling rate (CWF). Maximum values CWF and density rсf are obtained with the following characteristics: CEA = 20–28 wt%, MnO2/Al = 2–2.8 and Сgraphite = 4–6 wt%.
