Essay

Dissertation is devoting modernizing of technical - economical figures and quality stabilization of cast iron with spherical graphite in cast raw pieces (cast raw pieces for piston rings) under centrifugal casting in metallic mould, in first of all, by using rational regimes of modifying, optimization of chemical content and reduction of castings' thermal treatment. Have been investigated efficiency of spherical modifying master - alloys in shape of alloying master - alloys (alloys in the bases of Si, Fe, Cu, Ni) and brickets (pressed compounds of little materials fraction).
