Analysis of Efficiency Factors for Powder Materials Production

Purpose. Determination of the factors that have the greatest impact on the technological chain of the process of obtaining powder materials (metal granules). 

Methods. The study is based on an experimental approach and statistical analysis of the regression equation, built as a result of planning a multifactorial experiment of type 2³, which is used to find optimal conditions, build interpolation formulas, select essential factors, evaluate and refine the constants of theoretical models, select the most acceptable from a set of hypotheses about the mechanism of phenomena, etc. And also on the results of the experiment using the method of a priori ranking of factors using the coefficient of concordance and coding of natural variables. 

Results. Evaluation and analysis of the results of the experiment made it possible to establish that the most important factors influencing the efficiency of the production of powder materials are factor x₅ – rotation speed of the workpiece; factor х₁ – time of sieving and magnetic separation; factor х₆ – Power of the plasmatron. 

Conclusion. Experimental studies were carried out to vary the parameters of the main factors affecting the increase in the productivity of the technological process, the yield of suitable material and the quality of metal granules. Improving the control of the parameters of these factors (optimizing the spraying modes and improving the classification process) will allow obtaining the maximum yield of suitable material, increasing the quality of finished products (metal powders), obtaining an economic effect and improving the technical and economic indicators of the production chain of granules metallurgy. The data obtained can be used for further research, in which it is supposed to propose and implement various ways to improve the factors under study, which will optimize the technological process of pellet production.
