Olexiy A. Tchaykovsky Ferroborron Melting Kinetics in Thermite Mixture

Cast parts with differentiated features significantly reduce operating costs but their production connected always with difficulties. Direct use the in-mold process for alloying cast iron with high temperature ferroalloys is not possible because their low dissolution. Dissolution process can be intensifying with thermites mixture. The thermite burning time as a function of ferroboron fraction and ferroboron insertion diameters were investigate. Ferroboron fractions were in a range 1..5 mm. Ferroboron cylindrical insertions diameter were 10, 15, 20 mm. The conditions and characteristics of ferroboron-thermite system, which is achieved complete melting of ferroboron were investigated.

Key Word(s): double-layer, casting, part, in-mold, process, iron, aluminum, thermite, burning, kinetics, ferroboron, melting, kinetics.ferroborron, melting, kinetics, thermite, mixture
