Lime, as an intensifier of the sintering process, leads to improved agglomeration and permeability of the sinter mix. Lime addition into sinter mix indicates a positive effect on the heat content in the sinter bed leading to shortening sintering time and possible fuel savings. Based on experimental results, partial usage of lime in the sinter mix brings also a positive …

· Sintering, also known as frittage, is a thermal agglomeration process during which the atoms within the materials diffuse and form bridges across distinct particles, joining them together. Sintering involves heating products without melting them, and as such is particularly well-suited for materials with very high melting points.
