The face of scrap per ton of steel consumption decreased year by year, iron ore consumption of substantial growth situation, China scrap iron and steel applications Association asserted that the future will be gradually replaced by electric furnace steelmaking converter steelmaking advantage, scrap charge will also gradually replace the dominant iron ore, With the shortage of iron ore resources in China and the limited iron ore resources in the world, the steel growth process should: eat less ore and eat more scrap. Since the beginning of the 21st century, China's scrap steel application has the following characteristics: 1. The output of crude steel has increased significantly, with an increase of 290 million tons in 6 years, an increase of 225.9%, an average annual increase of 48 million tons, and a high growth period of steel production. 2. The total consumption of scrap steel increased significantly, with an increase of 38 million tons in 6 years, an increase of 130.14%, and an average annual increase of 6.33 million tons, but lower than the growth rate of crude steel, indicating that the supply of scrap resources is insufficient. 3. The consumption of scrap steel per ton has been decreasing year by year, and it has dropped 67kg tons of steel in 6 years, a decrease of 29.52%. The iron ore consumption has increased sharply, and is much larger than the growth rate of scrap consumption. It means that the high consumption of iron ore can make up for the tight resource allocation tendency of scrap resources, and the development is worrying. In this regard, China's Waste Steel Application Association pointed out that "less eating ore, eating more scrap" is the inevitable historical development. In expounding the above viewpoints, the association exaggerated, and the "Steel Industry Development Policy" clearly pointed out that it is necessary to "gradually reduce the proportion of iron ore and increase the proportion of scrap." Reduce the exploitation of primary resources, increase the utilization of recycling resources, and achieve a fair allocation of resources, in order to achieve a major strategic decision for the sustainable development of the steel industry. The association further explained that according to recent data released by the Continental Steel Association, by 2001, the world's proven reserves of recoverable iron ore resources were 140 billion tons, with a reserve base of 310 billion tons. In the past 10 years, the global iron ore output has exceeded 1 billion tons per year. In 2005, the global crude steel output was 1.129 billion tons, and the iron ore consumption exceeded 1.3 billion tons, which can be mined for about 100 to 200 years. By 2004, the base reserves of iron ore resources in the mainland were 21.97 billion tons, and the reserves of recoverable reserves were 11.8 billion tons. The annual mining volume of continental iron ore will exceed 600 million tons. According to this calculation, under the current mining technology conditions, China's iron ore mining period is only 20 to 40 years, and the situation is quite serious. Iron ore is a primary resource. The original resources are limited, non-renewable, and when there is exhaustion, the resource crisis has become a fixed trend. How to control mining and scientifically adjust resource allocation is imperative. Scrap steel is the only raw material that can replace iron ore in steel production, and the development and application of scrap steel resources to the maximum extent has become an important way to alleviate the iron ore resource crisis. With the development of the global economy, in the future steel industry format, electric furnace steelmaking will gradually replace the advantages of converter steelmaking, and scrap steel materials will gradually replace the dominant position of iron ore. It is expected that in this century, scrap steel will It has become an important supporting industry for the steel industry, and a small amount of iron ore mining and application will be used as a supplement to the natural consumption of resources. China's Waste Steel Application Association said that China must accelerate the process of industrialization, the world must accelerate the development of the global economy, the steel industry will continue to grow, and the increase in resource consumption is inevitable. However, there is a shortage of iron ore resources in the mainland and limited iron ore resources in the world. If the traditional development model is followed, industrialization with a large amount of primary resources will be unsustainable. To reduce the dependence of steel growth on iron ore, We must vigorously develop the economy of the loop--eat less ore and eat more scrap to promote the efficient use of resources and the global ecological balance.
