Development of Technologies for High Phosphorus Oolitic Hematite Utilization

With increasing consumption of iron ore over the world, new technology of beneficiation and smelting is more urgently needed than ever before to explore ores which, are difficult to utilise by beneficiation and smelting processes. Oolitic Hematite mines, iron ore with poor beneficiation efficiency are widely distributed in China with the most abundant deposits. In this paper, comprehensive technology integrating beneficiation and smelting processes was proposed. This paper reports the experimental results on ore beneficiation, pretreatment of hot metal with high phosphorus and dephosphorization during direct reduction. It would provide technology support for the efficient utilization of high phosphorus Oolitic Hematite, and also provide technology for industrial demonstrating projects.     

Heat transfer in an iron bath of a two-stage smelting reduction process

Mechanisms of the heat transfer by means of iron and slag drops in smelting reduction are discussed. The quantity of slag on the molten iron exists in two forms depending on the different processes: either a thin slag layer or a voluminous slag layer. In the case of a small amount of slag, iron and slag drops are spattered in the free space above the bath furnace. By smelting reduction with a high post-combustion degree, the spattered iron drops are quickly oxidized in the free space. The spattered slag drops transfer heat from the free space to the molten iron. A definition for the heat transfer efficiency in the iron bath of a two-stage smelting reduction process is presented. Experiments on heat transfer were made in an experimental EOF-furnace with 100 kg iron. The post-combustion degree and the heat transfer efficiency were on a high level, because inleaked air was used.     

Direct reduction and smelting reduction – an overview

A survey is given on the current state of direct reduction and smelting reduction processes. Several developments, such as coal injection, top-gas recycling etc., contribute to decrease the coke consumption in the blast furnace. Coal-based as well as gas-based direct reduction processes have not succeeded in Western Europe. These processes have only attracted economical interest in locations where there is a cheap source of energy. Other developments to reduce iron ore are concerned with the direct production of liquid iron in a smelting reduction process with a substantial part of the reduction taking place in the liquid oxide phase. The ideal concept of a smelting reduction process with direct use of fine ore and coal as well as only liquid state reduction to a liquid product similar to steel has not yet been realized.

Influence of blast-furnace conditions on the direct reduction of iron

The degree of direct reduction and the coke consumption in the blast furnace, which are not independent variables, are determined by the carbon-demand ratio for physical and chemical processes. The smelting conditions corresponding to the demand for carbon in reduction primarily affect the degree of direct reduction and consequently affect the coke consumption. The smelting conditions corresponding to the demand for carbon in heating processes primarily affect the coke consumption and consequently affect the degree of direct reduction of the iron oxides.
