Special Issue Information

Dear Colleagues,

Since the majority of the industry is still occupied by the lengthy iron and steel metallurgical process, of which ironmaking is the primary component, the focus of ironmaking technology development has switched to a low-carbon and green development model due to the quick development of typical low-carbon ironmaking technologies, including oxygen blast furnaces and hydrogen shaft furnaces. It is necessary to discuss innovative ironmaking technology through the Special Issue titled ‘Situation and Prospect of Ironmaking Processes’ to further promote the development of the ironmaking industry, addressing the industry's requirements for high-quality ironmaking technology, green and low-carbon development, quantitative control, and resource-intensive diversification. Papers on low-carbon ironmaking, intelligent detection, big data and mechanism fusion modeling, solid–gas–liquid simulation model, process optimization, and other associated technologies will be the main emphasis of this Special Issue.

The steel industry is an important foundation of the national economy and the livelihood of the people, producing a large amount of carbon dioxide gas, accounting for about 70% of the carbon dioxide gas generated in the steel industry, which occurs during the ironmaking process. Therefore, the key technology to reduce the pollution and improve competitiveness is to increase the stability of blast furnace production and the quality of hot metal. Since the operation requirements for temperature control in the vanadium-titanium blast furnace are dramatically different compared to the traditional ones due to the low fluidity of vanadium-titanium slag, maintaining the required hot metal temperature within a narrow range with smaller fluctuations is essential. In addition, the adjustment parameters of the lower part have a significant influence on the tuyere combustion flame temperature during the daily operation of blast furnaces. At present, there is no relevant research on the online detection and analysis of vanadium-titanium blast furnace tuyere combustion flame temperature. In this study, the temperature of four tuyeres in a 500 m3 vanadium and titanium blast furnace at Jianlong Steel was detected by an online detection system. The tuyere combustion flame temperature was then calculated using colorimetric temperature measuring methodology at various times and at four distinct locations. After that, the calibration analyses, imaging parameter and the temperature tendencies in different directions of the blast furnace were investigated. This study not only offers new methods for understanding the regularity of operation and increasing the degree of visualization in vanadium and titanium smelting blast furnaces but also provides technical support for intelligent and low-carbon operation in blast furnaces.
