Limiting Phenomena Related to the Use of Iron Ore Pellets in a Blast Furnace
Most of the iron in the world is produced using a blast furnace process, which has iron ore (iron oxides) and coke as its raw materials. When pellets are used in a blast furnace, the iron burden material is charged in the form of pellets and fine, iron-rich by-products are charged typically in the form of cold-bonded briquettes at the top of the blast furnace. Coke is the primary fuel and reduc...
متن کاملenvironmental effects of gol-e-gohar iron ore mine on groundwater of the area
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Effects of Blast Furnace Slag with Iron Ore Containing Rare Earth Elements on Combustion Characteristics of Pulverized Coal
The combustion characteristics of pulverized coal when using blast furnace slag charged with iron ore containing rare earth elements as a composite catalyst were investigated by thermo gravimetric analysis. The results show that the combustion char acteristics of pulverized coal loaded with 21.3% by weight of blast furnace slag containing 15% rare earth ore are better than those of others. It i...
متن کاملAccuracy of Discrete Element Method Simulations: Rolling and Sliding Frictions Effects-Case study: Iron Ore Pellets
The discrete element method (DEM) has been used as a popular simulation method in order to verify the designs by visualizing how materials flow through complex equipment geometries. Although DEM simulation is a powerful design tool, finding a DEM model that includes all real material properties is not computationally feasible. In order to obtain more realistic results, particle energy loss du...
متن کاملOptimization of a simulated iron-oxide pellets induration furnace
Induration furnaces for iron-oxide pellets are expensive processes, due to their high energy consumption. Moreover, they are highly interactive and then complex to control. Real-time optimization strategies based on reliable process models are thus necessary. However, induration furnaces are described by distributed-parameter models that require long computation times. The performance of IMCopt...
