Rdi of sinter
WebThe RDI is a very important parameter that is used as a reference in all sintering work and serves to predict the sinter's degradation behaviour in the lower part of the blast furnace stack. Secondary hematite, also known as skeletal rhombohedral hematite, is the main cause of a poor sinter RDI. WebJul 8, 2013 · Sinter degradation during reduction at low temperature is normally determined by the RDI static test, which is carried out at 550 deg C. Low values of RDI is desirable. Secondary hematite, also known as skeletal rhombohedral hematite, is the main cause of a poor value of the sinter RDI.
