Abstract

The cleaning of high chromium cast iron melt from scab, non-metallic inclusions and gases is an urgent task of obtaining the quality parts for shotcasting machines. In this work the authors showed the producing technology of blades castings for shotcasting machines. The infl uence of different deoxidants (Ti, Al, SIMISh-1, ZhKMK-6, FCM-6) on the quality and properties of high chromium cast iron castings was determined. The authors analyzed the contamination of non-metallic inclusions, investigated thermogram and polythermals density and iron with various deoxidants at different concentrations. The research has shown that to accelerate the formation of trigonal carbide and increase performance properties of chromium cast irons it is necessary to modify them with the complex modifiers that do not contain silicon.
