The increase in the usage of Australian iron ores means that the ore resources changed from hard hematitic to more goethitic pisolitic or Marra Mamba ores.
Intensification of the iron ore sintering process was approached by injecting hydrogenrich gas into the sinter bed. The location of the injection was critical to
Sinter is the primary feed material for making iron in a blast furnace. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control
In this case, the iron ore sintering process serves as the first step in the ironmaking process and provides the main raw material for the blast furnace. The

ABSTRACT Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slagforming elements and coke. The purpose of sintering is to
Basic sintering technology. The sintering technology is basically an agglomeration process for the iron ore fines which is dependent on heat to melt the surface of the smaller particles together to form larger
In the sintering of iron ores, the partial substitution of anthracite for coke breeze has been considered to be an effective way of reducing pollutant emissions and production cost. In this study
For the ferrous burden of blast furnaces in China, sinter generally accounts for more than 70% and the sintering process accounts for approximately 6–10% of the total energy consumption of the iron and steel enterprise. Therefore, saving energy during the sintering process is important to reduce the energy consumption in the iron and steel

The exhaust gases have a The sintering machine is a closed chain of moving sintering palettes moving along the rails by means of a drive, and on the lower part, under the action of
The iron and steel industry has made an important contribution to China’s economic development, and sinter accounts for 70–80% of the blast furnace feed charge. However, the average grade of domestic iron ore is low, and imported iron ore is easily affected by transportation and price. The intelligent ore blending model
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Owing to the depleting reserves of traditional high grade iron ore, there have been considerable changes in iron ore resources available throughout the world, especially in steel mills in East Asia. Corresponding to the changes
