FIELD: metallurgy.
SUBSTANCE: method includes manufacturing of mould with gate -feeding system, and ignition of plain thermit. Plain thermit contains iron-aluminium thermit and ferroalloys. By plain thermit it is filled hollow of mould with gate-feeding system. Ignition of plain thermit is implemented by gas-flame burner in top part of mould for implementation of energy-yielding reaction with formation in shell mould of steel melt and its following hardening.
EFFECT: increasing of casting yield.
