Iron Ore Sinter Pellets Reducibility

Herein the reducibility of the iron ore pellet sinter and lump ore in the BF shaft are focused on The experiments are conducted isothermally with a blast furnace simulator BFS hightemperature furnace at four different temperatures 700 800 900 and 1000 176C for 300 min

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
