    Jan 14, 2021  Sandi Johnson Date: January 14, 2021 Iron ore sintering is a type of powder metallurgy used to pretreat iron before using it in manufacturing applications Sintering involves heating iron powder to partially, but not completely, melt the iron particles The exact process used and additional elements involved vary, with some methods using gas or electricity in sinter iron ore was prepared as single tablet sample The samples were made from mixture of reagent oxides and they were prereduced to control their reduction degree to several reduction levels The tablet sample was rapidly heated up to 900°C, and then gradually heated up with 10°C/min under inert gas atmosphere and 01 MPa loadEffect of Prereduction Degree on Softening Behavior of Nov 16, 2020  Sinter analogues designed to simulate the bonding phase in iron ore sinter were prepared from Australian iron ore fines using an infrared rapidheating furnace The equipment and procedure is described in previous work 18 A 1mm fraction of the iron ore was fluxed to a binary basicity (CaO/SiO 2 ratio) of 20 using reagent grade CaCO 3 with Effect of Temperature, Time, and Cooling Rate on the
