Sintering & Basicity Control

The basicity of sinter feed material is an important parameter in the efficient operation of the sintering and ironmaking process. Proper addition of lime to stabilize the basicity of the sinter product delivers benefits not only to the sinter operations but to the downstream ironmaking process. Carmeuse has developed a solution which combines an engineered quality lime, and an online chemistry measurement, allowing to adjust feeding rate to ensure a stable basicity index of the sinter feed. This solution leads to a stable and reliable process in the blast furnaces.
