Abstract: The technology for clean steel production in modern steel plant is analyzed, a philosophy with production efficiency, manufacturing cost and product performance in its core. A review on functions is also made which of high-efficiency, low-cost and high-quality steel products manufactured by the new generation iron and steel plant, in combination with the study on design of steelmaking – continuous casting process of Shougang Jingtang iron and steel plant. By applying precise and dynamic design system to optimize and allocate systems and working procedures of hot metal pretreatment, converter smelting, secondary refining, continuous casting process, etc, a platform of high-efficiency, low-cost and high-quality clean steel production is built.

Abstract: In recent years great progress is made in technical equipment of large blast furnace in China. A series of new process, technologies and equipment, integrated and developed on our own, are applied on newly built large blast furnaces and have been proved to be highly effective. After more than 20 years’ development and innovation of the bell-less top equipment designed and developed on our own, it has reached the advanced level in the world in terms of equipment reliability and service life; fully-dry impulse bag filter dedusting technology of BF gas, which is also developed on our own, has gained technical breakthroughs in terms of optimized system design, gas temperature control, pneumatic conveying of dedusting fines; the integrated innovative high-efficiency long-life high-temperature technology, through applying high-temperature preheating technology of combustion air, improving heat transfer efficiency of hot blast stove and optimizing structure of the hot blast stove system, enables the blast temperature to reach 1250°C with BF gas as fuel.
