COREX furnace, also known as smelting reduction ironmaking unit, has the advantages of short process and low pollution, and is a revolution in traditional blast furnace ironmaking technology. Its completion is an important measure for Baosteel to create an environmentally friendly enterprise. It is an important project to realize Baosteel's new round of strategic development planning, and it has also created a brand new era for China's ironmaking technology.
The Luojing project successfully produced iron, which is the result of fully utilizing the synergy effect of Baosteel. Baosteel used a large number of new processes, new technologies and new equipment in the construction of COREX furnace. At the same time, it also draws on the rich experience of Baosteel Branch's blast furnace construction and production preparation. Participating in the design, equipment manufacturing, construction, engineering quality supervision, supervision, information construction and procurement system of the project construction, under the strong support of Baosteel integrated platform, efforts to overcome a series of difficulties in new technology, short construction period and high requirements. To ensure that the COREX furnace was built on schedule.
In order to solve the risks brought by the large-scale COREX furnace, stabilize and improve the operation efficiency, and achieve the goal of achieving production and achieving efficiency as soon as possible, Pugang cooperated with the Austrian Steel SV experts, Baosteel researchers and iron-making experts in design. Targeted improvements, such as the installation of a universal distributor, the dynamic fabric of coal fuel; the depth of the dead iron layer increased by 200% based on the original design, which is conducive to reducing the circulation of molten iron and reducing the sidewall of the furnace Erosion of refractory materials. In addition, under the support of Baosteel Research Institute and Baosteel Branch, Pudong Iron & Steel Co., Ltd. effectively promoted more than 10 researches including “New Mud Mud in the New Environment of COREX Furnace†and “Technology Development of Coal Briquetting Technologyâ€. Question.
With the strong support of Baosteel Co., Ltd., combined with the operation method of large blast furnace, Pudong Steel Company has cultivated the first generation of COREX furnace operators.
Create a new stage of China's non-blast furnace ironmaking technology Baosteel built COREX furnace
At 11:08 on November 8th, Pugang, which stood under the blue sky and white clouds, relocated the COREX furnace of Luojing Project, achieving the goal of ironing one day ahead of schedule. The world's largest COREX furnace with an annual output of 1.5 million tons of molten iron was built in Baosteel, marking a new stage in China's non-blast furnace ironmaking technology.
