The Using Boron-containing Materials in Ferroalloy Industry


The article presents an analytical review of the use of boron-containing materials in ferrous metallurgy. Literature data are given on the improvement of the properties of steel with the addition of an ultra-small amount of boron. The review presents the main existing technologies for the preparation of boron-containing alloys and their features, as well as methods for introducing boron into steel. In domestic and foreign production, ferroboron has been widely used with 6–20% B. Due to the high chemical activity, part of the boron transferred to the metal reacts with nitrogen. A number of methods have been proposed in the literature for preventing boron binding. One of them is the introduction of boron by complex boron-containing ferroalloys with 1–2% B. Using this method increases the degree of transition of boron to metal. The review shows the possibility of wide use of boron-containing materials in the processes of ferrous metallurgy.
