FIELD: metallurgy.
SUBSTANCE: invention elates to water recycling schemes and can be used in metallurgy. Method includes withdrawal of waste heated water from vacuum vessel into sedimentation tank, following filtration of settled water on filter plant, which is formed from pressure filters with granular filtering charging, grains diametre of which successively decreases top-down in the direction of flow of filtered water, and working pressure on inlet of which is kept at level 0.30-0.40 MPa at pressure difference on filter plant 0.04-0.12 MPa, after what filtrate is fed to cooling into cooling tower and then again to vacuum vessel. Additionally filters are in turn transferred into cleaning mode, at the first stage of which into filtering charging bottom-up it is fed compressed air, at the second stage bottom-up it is fed water.
EFFECT: at usage of invention it is provided increasing of effectiveness of steel degassing.
