A New Concept of Halide Sinter

Use of halide solution to improve the RDI and RI of sinter : # The reduction-degradation index (RDI) of sinter is an important parameter to estimate the quality of sinter in low temperature zone (450-550C) of blast furnace. Hence, it is of great importance to reduce the RDI of sinter which improve the permeability of blast furnace burden column for a stable and smooth performance resulting high yield and low consumption. In the last few years, many researchers have studied and reported the method for improving sinter quality by adding halide solution on to surface of the manufactured sintered ore. Some sinter producers also established from practices that spraying CaCl2 solution on to the sinter surface will reduce the RDI of sinter.
