The softening–melting properties of mixed ferrous burden made from high-basicity sinter with increased MgO and Al 2 O 3 content and acid pellets was investigated for optimization. The influences of MgO and Al 2 O 3 are discussed with the aid of phase analysis. The results showed that, with decreasing MgO mass%/Al 2 O 3 mass% in mixed burden, all …

Understanding Sinter and Sinter Plant Operations. Sintering is a process of agglomeration of fine mineral particles into a porous and lumpy mass by incipient fusion caused by heat produced by combustion of solid fuel within the mass itself. The sintering process is a pre-treatment step in the production of iron, where fine particles of iron ...
