Granules containing agglomerated bulk material

Granules containing at least one agglomerated reactive bulk material and a binder matrix, wherein the binder matrix contains an inorganic salt as the binder, wherein the reactive bulk material is a bulk material that undergoes a violent and immediate chemical reaction when granulated in the presence of water and the proportion of bulk material in the granules is in the range from 85 to 99% and the melting point of the binder is below 600° C. and wherein the apparent density of the granules is in the range from 0.7 to 1.2, wherein the binder contains one or more of calcium nitrate, and/or boron trioxide.

Method for the improvement of steel or refractory comprising adding granules according to claim 6, in the manufacture of steel or refractory.
