The consumption of scrap steel replacing iron ore is about 60million tons

the safety share is guaranteed from January to November 2018, and China's cumulative crude steel output increased by 6.7% year-on-year; The cumulative pig iron output of Enterprises above designated size increased by 2.4% year-on-year, 4.3 percentage points lower than the increase in crude steel output. Due to the increased use of scrap steel, the consumption of iron ore has been replaced by about 60million tons. This shows that the composition of the main raw materials for China's steel production is undergoing gratifying changes, which has promoted the green development of the steel industry -

on December 22, the 2018 (seventh) China steel raw material market high-end forum with the theme of "building a green supply chain to boost the high-quality development of steel" was held in Beijing. It was learned from the forum that the composition of the main raw materials for China's steel production is undergoing gratifying changes, the use of scrap continues to rise, and the role of replacing iron ore consumption and promoting the green development of the steel industry is increasingly apparent

the use of scrap steel has increased significantly

in 2018, China's steel production hit another record high. From January to November 2018, China's cumulative crude steel output was 857 million tons, with a year-on-year increase of 6.7%. The monthly crude steel output was significantly higher than that in 2017, with an average daily crude steel output of 2.567 million tons. According to the prediction of metallurgical industry planning and Research Institute, China's crude steel output will reach 923 million tons in 2018

it is worth noting that in the case of a significant increase in crude steel production, China's pig iron production has not increased significantly, which is due to the increase in the use of scrap steel. Lei Pingxi, chief engineer of China Metallurgical Mining Enterprises Association, introduced that from January to November 2018, the cumulative pig iron production of Enterprises above designated size was 707.85 million tons, an increase of 2.4% year-on-year, 4.3 percentage points lower than the increase in crude steel production. The increase in pig iron production increased the consumption of iron ore by about 28million tons, and the use of scrap steel increased the consumption of iron ore by about 60million tons

it is reported that scrap steel is a green raw material for the iron and steel industry and the only ferritic raw material that can replace iron ore in a large amount. Using scrap steel to produce 1 ton of steel can save 1.6 tons of iron ore, reduce energy consumption by 0.35 tons of standard coal, and reduce carbon dioxide emissions by 1.6 tons, which has significant energy conservation and emission reduction benefits

in recent years, with the promotion of supply side structural reform, especially the complete elimination of "ground bar", the utilization of scrap in regular steel mills has increased significantly. According to the data provided by China scrap iron and Steel Application Association, the total scrap consumption in 2017 was 147.91 million tons, an increase of 57.81 million tons over the previous year, an increase of 64.2%, and the scrap ratio was 17.8%, an increase of 6.7 percentage points year-on-year. In 2018, the total consumption of scrap steel in China is expected to be 187 million tons, with a scrap ratio of about 20%

policies encourage the comprehensive utilization of resources

"with the increase of China's steel reserves and scrap resources, as well as the prominent price advantage of scrap, the total amount of scrap resources in China will be very sufficient in the next 20 years." Wang Fangjie, Deputy Secretary General of China scrap iron and Steel Application Association, said

it is reported that by 2020, China's iron and steel reserves will reach 10 billion tons, and the annual output of scrap resources will exceed 210 million tons; By 2025, China's steel reserves will reach 12 billion tons, and the annual output of scrap resources will reach 270 million to 300 million tons; By 2030, China's steel reserves will reach 13.2 billion tons, and the annual output of scrap resources will reach 320 million to 350 million tons

sufficient scrap resources can provide strong support for the development of China's iron and steel industry. Wang Fangjie and other participating experts believed that the composition of iron resources in China's iron and steel industry will change significantly, and the demand for international iron ore resources will gradually decline. At the same time, it will play an important role in promoting the construction of ecological civilization and green development

"the contribution of scrap to crude steel output is further improved. It is planned that the average scrap ratio will reach 20% by 2020 and 30% by 2025. The current value is gradually approaching this level." Lei Pingxi said that the scrap ratio of converter has exceeded 13% on average, and the short process capacity of electric furnace is gradually being released

it is gratifying that the utilization of scrap steel is ushering in new policies. Gaoyunhu, director of the Department of energy conservation and comprehensive utilization of the Ministry of industry and information technology, said that China will vigorously promote the comprehensive utilization of scrap resources and study industrial policies conducive to the resource-based, large-scale and high-quality utilization of scrap enterprises. By encouraging iron and steel enterprises to improve process technology and process structure and increase the proportion of electric furnace steel, we will continue to improve the utilization rate of scrap steel

from the perspective of international comparison, the global average scrap steel-making ratio in 2017 was 35.5%, while that in the United States and the European Union were 72.1% and 55.5% respectively. China's scrap steel-making ratio is still low and still needs to accelerate its development

"the iron and steel industry is an important basic raw material industry, which plays an irreplaceable supporting role in the development of the national economy. We must speed up the transformation and upgrading." Li Xinchuang, President of the metallurgical industry planning and Research Institute, said that China's iron and steel industry is still facing problems and challenges such as environmental protection pressure, capacity expansion, high external dependence on raw material security, and slow construction of overseas low-cost high-quality resource bases. We should continue to deepen supply side structural reform, focus on building a green raw material supply system, and better promote the green and high-quality development of the iron and steel industry

restrict the import of low-grade iron ore

for a long time, China's iron and steel production is dominated by the long process with iron ore as raw material, while the short process of electric furnace with scrap as raw material accounts for a relatively low proportion. China is a big consumer of iron ore, but due to the limitation of domestic iron ore resource endowment, it needs to import a large amount of iron ore every year to meet the demand. In 2017, China imported 1.075 billion tons of iron ore, with an external dependence of 88.7%. In the first 11 months of 2018, China imported 978 million tons of iron ore, a year-on-year decrease of 1.3%

while welcoming the strengthening of scrap substitution, experts attending the meeting also paid attention to the "big head" of iron ore consumption. Li Xinchuang pointed out that although a large number of imported iron ore solved the domestic demand gap, it also brought many problems. The use of some high pollution and low-grade imported iron ore not only increases the cost of pre iron process and the production cost of iron and steel enterprises, but also causes serious environmental pollution, and the subsequent ecological treatment will pay a high price

it is understood that the "strictest" ultra-low emission standard in history will be implemented, and the steel industry is facing a big test. Ultra low emission terminal treatment technology is difficult and costly. Usually, a set of activated carbon flue gas desulfurization and denitration integrated treatment device is invested more than 200million yuan, and the annual operation cost is more than 100million yuan. Using low sulfur high-grade iron ore can greatly reduce the end treatment cost

"relevant standards and classification grades of imported iron ores should be formulated to determine the specific parts of wear, and the research on standards such as the quality of metal mineral products, the limit of impurities and harmful elements should be strengthened to reduce environmental pollution." Li Xinchuang suggested that we should promote the formulation of national standards for the quality of imported iron ore products, including new TPE grade standards that can be adhered to various engineering plastic materials, prohibit the import and use of low-grade and highly polluting fines and pellets, and restrict the import and use of low-grade fines
