Ironmaking equipment and ironmaking methods

Abstract

The invention relates to an iron-making device and an iron-making method which significantly reduces generation amounts of environment pollutants and reduces energy consumption in a raw material processing step and an iron-making process, thus achieving environment protection and manufacturing steel plates with high quality. The iron-making device and the iron-making method are provided. The iron-making device comprises a molten iron manufacturing device for manufacturing molten iron by utilization of fine iron ore; a steel-making device subjecting the molten iron manufactured in the molten iron manufacturing device to steel making to manufacture molten steel; a continuous casting machine for casting the molten steel manufactured by the steel-making device to manufacture a cast sheet; and a rolling device for rolling the cast sheet manufactured in the continuous casting machine. A cast sheet soaking device is disposed between the continuous casting machine and the rolling device and is configured to evenly control the temperature of the cast sheet.

Description

technical field [0001] The present invention relates to ironmaking equipment and ironmaking methods, in particular to significantly reducing the amount of environmental pollutants produced in the raw material treatment process and ironmaking process and reducing energy consumption, so that it can produce iron with excellent quality while being environmentally friendly. Steel plate ironmaking equipment and ironmaking methods. Background technique [0002] Generally, molten steel is produced by using molten iron produced in a blast furnace as a main raw material and refining it in a converter. [0003] At present, in the production of molten iron, no ironmaking process has been developed that can surpass the blast furnace process in terms of energy efficiency or productivity. However, in such a blast furnace process, it is necessary to rely on Coke, which is processed from specific raw material carbon, mainly relies on sintered ore that has undergone a series of agglomeration...

AI Technical Summary

Problems solved by technology

[0004] That is, the current blast furnace process must be accompanied by raw material preparation processing equipment such as coke manufacturing equipment and sintering equipment. As a result, additional auxiliary equipment must be constructed in addition to the blast furnace equipment, resulting in a huge cost requirement for the equipment.

[0005] And, in the above-mentioned raw material preparatory treatment equipment, will produce SO x , NO x There are quite a lot of environmental pollutants such as dust or dust, and thus special equipment for purifying them is required. In particular, the current worldwide regulations on environmental pollution are becoming more and more stringent, so in order to overcome these situations, It requires a huge investment in processing equipment, etc., but this will actually reduce its competitiveness for the current production of molten iron by means of the blast furnace process
