The results of research on the development of technology and the creation of boron-containing steels intended for protection
against radiation, including hard neutron- and g-radiation, are presented. An analysis of the behavior of boron in the smelting of
converter steel with ladle processing and casting in continuous casting machine (CCM) has performed. The physicochemical
characteristics of the processes of formation of the structure of steel with the participation of the effective boron Вef have been
determined. For steel grade B of ASTM A514 standard, a production technology is developed and tested under industrial
conditions to obtain a high content of effective boron Вef in it. A calculated boron assimilation coefficient is established to
be of 0.95 upon receipt of a continuously cast billet. The uniformity of the distribution of effective Вef boron in the matrix is
characterized by the value of the annealed metal layer, determined by standard measurements of hardness. Based on the
results, a technology is proposed for the production of converter steel with multi-reagent ladle processing and casting on a
continuous casting machine in a continuously cast billet, providing a hardened layer depth of up to 40, and in some cases up to
50 mm, further increasing the protective properties of ASTM A514 grade B steel against hard neutron penetration and g-radiation
by 4–5 times. The proposed technology, the main technical solutions of which are protected by the Ukrainian patent for an
invention, has been tested under industrial conditions and can be used for smelting anti-radiation steels for various purposes.

Keywords: Anti-radiation steels, converter production, radiation, boron-containing steels, radiation protection, polyreagent ladle treatment of steel, effective boron, steel gauge.
