FIELD: metallurgy.
SUBSTANCE: invention relates to the field of ferrous metallurgy, in particular to the production of a semi-finished product in the form of a semi-finished product for steelmaking. Semi-product is made in the form of a steel capsule filled with iron-containing material, used as a pre-crushed waste for cleaning the surface of steel billets before the rolling and the scale from 5 to 250 mm in size.
EFFECT: invention makes it possible to reduce the consumption of scrap metal and improve the quality of the steel produced, as well as to reduce its cost.
