Treatment of Melts by Powder Materials in Foundry

Description

The developed and tested in industrially equipment and technologies allow to reduce the content of sulphur:
in steel ————— to 0.008%,
in cast iron ——— to 0.005%;
oxygen ————— 1.5-2 times;

Also this equipment and technologies allow to reduce casting rejects on cracks and gaseous porosity 2-3 times and to achieve the improvement of plastic properties and impact toughness.
