The iron ore at room temperature is loaded from the furnace top, which is located at the height position between 22 and 23 m in Fig. 4(a), and it is heated through the heat exchange with the gas. The iron ore starts melting when the temperature reaches around 1200 °C, which leads to the decrease of ore volume ratio at the height position between 2 and 3 m in Fig. 4(b).

It is likely that excess domestic scrap supply will, in the first instance, be used to reduce hot metal ratios in oxygen furnaces, yet the implications for iron ore demand are similar. While total global demand for iron ore is expected to peak around 2025, the decline in the ensuing decade will likely be gradual.

The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.
Oct 10, 2017· The first step in the production of steel or cast iron alloys is the reduction of iron ore, which contains iron oxide and gangue or mineral impurities, to unrefined hot metal or pig iron. The blast furnace is currently the key tool for ironmaking.
Scrap consumption among China's blast-furnace steelmakers are expected to remain steady at a relative high ratio of 15-18% nationwide in the near term due to its remaining pricing competitiveness against hot metal, market sources shared on April 3.Mysteel's price of 6-8mm scrap in Tangshan, North China's Hebei province was at

Generalized constructal optimization of a blast furnace is performed. • Maximum hot metal yield is taken as the optimization objective. • Optimum distribution of each raw material cost in the total cost is obtained. • Effects of blast parameter, agglomerate ratio and pulverized coal dosage are analyzed.
al hot-metal pretreatment methods using torpedo ladle cars or mol-ten metal ladles as the reaction vessels enabled stable production of low-P, low-S steels, but it required desiliconization at a prior stage, and as a result, the thermal allowance for the decarburization in con-verters decreased and the scrap ratio was significantly restricted. As
Since slag from previous blooms may have a high iron content, it can also be broken up and recycled into the bloomery with the new ore. In operation, the bloomery is preheated by burning charcoal, and once hot, iron ore and additional charcoal are introduced through the top, in a roughly one-to-one ratio.
