Granules containing agglomerated bulk material

Granules consisting of at least one agglomerated reactive bulk material and a binder matrix, wherein the binder matrix contains at least one organic or 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 and wherein the granules have a grain size of 1 mm or above.

Method for the improvement of steel or refractory comprising adding 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, and wherein the granules have a grain size of 1 mm or above, wherein the binder contains at least one mineral selected from the group consisting of calcium nitrate and boron trioxide in the manufacture of steel or refractory as input material.
