Attention to development of low carbon steel
Commitment to the task of downstream industries provide the bulk of the basic raw material for the steel industry, the rapid development stage in the national economy, steel demand, pulling crude steel production is increasing, the amount of energy consumed by the steel production continued to grow. China's iron and steel industry about 15% of the total energy consumption of the country's industrial energy consumption, iron and steel industry, wastewater and solid waste emissions accounted for 14% and 17% of the total industrial emissions, which is the main reason to cause the image of the "stinky tofu" . As energy-hungry steel industry to take the initiative to undertake the important task of energy saving.
Steel future national resources "report published by the American Iron and Steel Industry Association in 1995, said:" The future of the steel industry is the economic development of strong, dynamic and environment-friendly, low-power sectors of the economy. "Total U.S. carbon dioxide emissions (6260 facilities) for the 3.2 billion tons equivalent, of which the metal manufacturing industry (2692 facilities) carbon dioxide emissions by 100 million tons equivalent, of which from about 72.74 million tons of iron and steel industry equivalent to only 2.27%. In contrast point of view, the level of China's steel industry, energy
saving and the U.S. steel industry are far apart.
Worldwide, the U.S. steel industry is a ton of steel energy consumption
and carbon dioxide emissions in countries with the lowest, these results are only achieved through development and use of high-end technology. For example, the United States three transformational technology: two-way straight cylinder (PSH) ironmaking process, the molten oxide electrolysis ironmaking technology (MOE) and suspended iron reduction process in the next 10 years to 15 years, will be widely used. This means that the changes of a technological revolution and the production process in iron and steel industry is on the rise. China's steel industry energy saving technology integration has made great achievements, but basically the last century, the technology developed in the 1990s, such as bell-less top top burning stove, CDQ, CDQ technology. TRT blast furnace gas residual pressure power generation technology. More steel companies are also keen on expanding the scale, emphasis on the construction of large-scale blast furnace, large converter and a large strip rolling mill and other equipment, rather than focus on low-carbon steel deep-level technology development, technological innovation. If this continues, perhaps 10 years to 15 years, we in the low-carbon production in turn lags far behind Western countries.
