Paper Title:
Experimental Study on Lump Iron Ores as Sintering Hearth Layer
  Abstract

In the laboratory condition, a series of experiments were carried out in a sintering pot when Hamersley, Niuman and Hainan lump iron ore were used as sintering hearth layer instead of the recycled sinter. The results show that the sintering productivity is increased by 1.3%, 2.6 % and 13.2 %, and the fuel consumption is decreased by 4.4%, 2.0 % and 6.6 %, respectively. Meanwhile, the tumbler strength and the reduction disintegration index of sinter are also improved. During sintering experiments, the crack of two lump iron ores used as hearth layer didn’t happen. Through using the new technology, the combined water and the sulfur impurity were effectively decreased in the sintering products. Furthermore, the micro-porosity of the sintering products was found to increase, which will contribute to improve the metallurgical properties of sinter.
