Despite research and development reducing the requirement of steel for service utilities, demand will continue to increase to satisfy higher living standards. However, there are doubts about maintaining supplies of raw material and coking coal. On the other hand, when the price of any commodity increases, the market for it becomes sluggish. The price of steel will inevitably go up because the supply of coking coal has to be restricted for future requirements. Keeping this in mind, steel is still expected to be replaced by light metals, superplastic alloys, synthetics, ceramics, and fiber-reinforced materials, the prices of which will likely be cheaper than that of steel.
Hot reduced iron from the shaft goes to the smelter gasifier where coal and oxygen are injected such that the desired temperature of 1600–1650°C for slag–metal separation is reached. The hot-metal tapping temperature is approximately 1400–1500°C. Since coking and sintering plants are not required in the Corex process, substantial cost savings of up to 20% can be achieved in the production of hot metal. Regarding environmental concerns, Corex plant emissions only contain insignificant amounts of NOx, SO2, dust, phenols, sulfides, and ammonium.
India is endowed with good-quality large deposits of iron ore, but the deposits of coking coal are insufficient both qualitatively and quantitatively. Steel production will continue to grow throughout the world, but in the Western world the growth rate is likely to decelerate. Developing countries like India will try to become self-sufficient by increasing the rate of production. Significant shifts in the foreign trade balance for steel are also anticipated. Slowly but surely, importing countries will become exporters, and India will be one of them.
