Pangang’s energy-saving and environmental-friendly coking technology. Keywords: Coking technology. Abstract: A new technology research project aimed at making the coking process more economical and environmentally friendly – the SCOPE21 new coking technology research – is currently progressing steadily. SCOPE21 technology is a new coking technology developed abroad in recent years, and it has been put into large-scale industrial production in Japan. A new technology research project aimed at making the coking process more economical and environmentally friendly – the SCOPE21 new coking technology research – is currently progressing steadily. In order to research and develop more advanced coking production technologies and promote further energy conservation, emission reduction, and sustainable rapid development at Panzhihua Iron and Steel Group, the Steel Research Institute launched the “SCOPE21 New Coking Technologies Research” project at the beginning of this year. The researchers in this team have made use of the available resources to carry out their work promptly, and have successively completed research on domestic and international information regarding new coking technologies under SCOPE21, as well as the preparatory work for preliminary experiments under the current conditions. This includes collecting coal samples for experiments and conducting industrial analyses, as well as preparing coal suitable for coking in accordance with the requirements of the experiments. SCOPE21 technology is a new coking technology developed abroad in recent years, and it has been put into large-scale industrial production in Japan. Compared with traditional coking technologies, this new technology offers significant advantages such as energy and resource conservation, increased production and reduced consumption, as well as an expanded range of coking coal sources. Coke ovens based on SCOPE21 technology use refractory bricks with high heat transfer rates, enabling rapid heat transfer; the coke-making temperature is much lower than that of conventional ovens, and waste gas is fully utilized to preheat coal powder. This process causes a dramatic change in the properties of the coal; after it is fed into the coking furnace, it is heated to a certain temperature, and then the coke is placed in a sealed container where it remains for a specific period of time. In this way, compared to traditional coking processes, the coking time is significantly reduced. Furthermore, since this technology involves first rapidly heating the raw coal to a certain temperature and then feeding it into a coke oven for dry distillation at a conventional heating rate, the rapid heating process enhances the cohesion of the coal fed into the oven. This improves the availability of coking coal resources and increases the flexibility in their use; it allows for a significant increase in the proportion of weakly cohesive or non-cohesive coals used in coking blends. At present, the new coking technology of SCOPE21 is still a new topic in China; aside from Panzhihua Iron and Steel, no research institutions or enterprises have carried out related research. Its core technology lies in how to rapidly heat coal from room temperature to its softening temperature, achieving a high heating rate; it also includes the thermal shaping technology of coking coal under sealed medium-temperature conditions, as well as the thermal charging technology for coal powder at medium temperatures. To this end, since the second half of the year, the research team has been using a heating method in the laboratory to study the impact of parameters such as heating rate on the properties of coal coke.
