Blast furnace process has gone through 300 years of development, is the major iron-making technology, but the process complexity, high energy consumption and serious pollution and other shortcomings is difficult to be improved through the technological transformation of the general. Tons of iron blast furnace **** rate of the international advanced level of 400kg / t so, key enterprises in China's tons of iron **** iron is about 500kg / t, accounting for 50% of energy consumption per ton of steel. Only 900 million tons of coking coal reserves, according to the current development speed, only used for 30 years or so. This proposed non-blast furnace method. Including non-metallurgical technology of blast furnace smelting reduction process, gas-based direct reduction processes, coal-based direct reduction production of sponge iron crafts. Smelting reduction process is two-step refining process, although they could not only coal ****, but it will eventually restore and pre-reduction were carried out on different devices, making the process significantly reducing the effectiveness and inferior thermal efficiency of blast furnace process, This can avoid the high coal consumption, high energy shortcomings. Gas based direct reduction process is mainly based on natural gas as raw material, although less polluting, energy consumption is not high, but because of a serious lack of natural gas resources, it is difficult to promote in our country in general. Although coal-based direct reduction method can take full advantage of the rich coal resources, but because of the need at about 1000 ?high temperature reduction of iron ore into sponge iron will, so is still difficult to overcome the problem of high energy consumption. In recent years, China's metallurgical workers, such as the Iron and Steel Research Zhao Pei et al, proposed low-temperature coal-based direct reduction method, this is a groundbreaking theory and technological breakthroughs. This new technology to "fine powder", "high activation" as ideas, about 600 ?in the direct reduction of iron ore fines using coal quickly restore magnetic separation process has been cooled by low sulfur, phosphorus and silicon content of the pure iron. Rapid process of coal-based low-temperature basic characteristics are: (1) a high degree of fine iron ores and coal activated; (2) the mechanical force for chemical reactions; (3) low reaction temperature, reaction speed. This process can be first iron ore, coal and catalyst on the high ball mill grinding to the required fine-grained, and of the ball or making the block, in the 400 ~ 900 C in the heating and reduction equipment obtained through the reduction reaction sponge iron; You can also iron ore, coal and catalyst on the high ball mill, ball mill and heated to 300 ~ 600 C, reduction of iron ore in the milling process, and then remove the gangue by magnetic impurities to get more pure iron powder, briquette, etc. treated by the electric arc furnace or converter steel as raw materials. Experiments show that the 600 ~ 900 C for 60 minutes, the reduction rate of up to 95%; in 300 ~ 600 C under 120 minutes, more than 90% reduction rate. Faster than the reduction of a variety of sponge iron has a direct reduction process. Preliminary work has shown many advantages of this new technology: (1) coal as reducing agent, does not require ****; (2) new process tons of iron coal consumption can be reduced to 300kg, less than the blast furnace blast furnace smelting process and other non- iron technology; (3) was significantly lower than the CO2 produced by the existing blast furnace and smelting reduction process; the low reaction temperature, exhaust NOx, SOx significantly reduced; (4) As the reaction temperature is low, the amount of cooling water substantially reduced; (5) As the melting temperature is low, phosphorus ore, sulfur, silicon and other compounds difficult to be restored and retained in the gangue, while the carbon solubility in solid iron in a small, clean and iron for the production of this create the conditions; (6) The iron has a strong magnetic (much larger than the magnetite powder), so easily by magnetic separation method to remove non-magnetic materials, separation ratio can reach 80%, resulting in phosphorus and sulfur , silicon and other impurities in the clean iron low.
