After Shanxi Province formulated the "Coke Industry Adjustment and Revitalization Plan of Shanxi Province" last year, news of the introduction of the "Shanxi standard" for blast furnace coke has continued to spread. According to relevant personnel of the Shanxi Coking Association, the formulation of the "Shanxi standard" for blast furnace coke has been completed and it has now entered the approval stage.
The "Shanxi standard" is higher than the current "national standard" and meets the market demand. According to relevant persons involved in the formulation of standards, the "Shanxi standard" set in this section is higher than the current "national standard", and the classification is mainly based on the difference in coke of different blast furnaces. Requirements standards.
At present, the standards adopted in the coke industry are still GB/T1996-2003 national standards formulated by the State Ministry of Metallurgy in 1995, referred to as “GBâ€. Since the formulation of “national standardâ€, after more than ten years of development, the coking industry has made considerable progress. The coke oven has changed from the original earth coke oven and modified coke oven to the current large-scale machine coke oven, and the coal blending technology has made great progress. . As a major iron and steel producer of blast furnace coke, with the development of large ironmaking blast furnaces, the standard requirements for coke have also undergone great changes. Whether it is from the development of the coke enterprise itself or from the needs of the iron and steel companies, the existing "national standard" has been difficult to meet the current needs. Therefore, the formulation of "Shanxi Standards" has filled this need in a timely manner.
Aiming at national industrial policies to support the transformation and upgrading of the steel industry The blast furnace coke is the main raw material for the blast furnace smelting of iron and steel enterprises, and more than 90% of the blast furnace coke is used for blast furnace smelting. Different volumes of blast furnace coke quality requirements are different. The larger the volume of the blast furnace, the higher the demand for coke quality. With the advancement of energy conservation and emission reduction in China, the pace of eliminating backward production capacity in the steel industry has been accelerating. Judging from the timetable set out in the national iron and steel industry policy, by the end of this year, blast furnaces below 300 cubic meters of iron and steel enterprises should be completely phased out. By the end of 2011, 400 cubic meters of blast furnaces will be eliminated. At the same time, we must eliminate blast furnaces below 1,000 cubic meters in places where conditions permit. Large scale blast furnaces in steel companies will become an irresistible trend.
To this end, the formulation of "Shanxi Standards" must first consider the trend of large scale blast furnaces in iron and steel enterprises. According to relevant experts involved in the formulation of the "Shanxi Standard," one of the purposes of the "Shanxi Standard" formulation is to implement the national macro-control policy, support the upgrading of the national steel industry, and support the large-scale development of blast furnaces in steel enterprises through "standards." .
Two indicators, showing the unique competitiveness of Shanxi's coke According to related sources, in addition to the "national standard", in addition to the common *, gray, mechanical strength and other indicators, the "Shanxi standard" is the most obvious place to improve the coke The "responsive" (CRI), "post-reaction intensity" (CSR) two indicators.
In the process of blast furnace ironmaking, coke is an exothermic agent for blast furnace smelting, a reducing agent, and a furnace charge skeleton in the blast furnace, which plays an important role in the blast furnace production process. Among them, the CRI of coke directly affects the calorific value of coke, and the calorific value is not enough, which will increase the fuel ratio and coke ratio of ironmaking, thereby increasing the production cost. CSR affects the breathability of blast furnaces. If the reaction intensity of the coke is insufficient, the coke is easily broken and generates powder in the furnace, which affects the air permeability in the blast furnace, thereby affecting the forward running of the blast furnace. It can be seen that the post-reaction strength of coke is very important in the blast furnace smelting process.
According to the relevant person in charge of the Shanxi Coking Co., the advantage of Shanxi coke is not only because of its large quantity, but also its high quality and irreplaceability compared with coke in other parts of the country. The key to this irreplaceability lies in the fact that "Shanxi coke" has a good post-reaction strength to ensure the smooth operation of blast furnace smelting. This is crucial for blast furnace smelting. Therefore, the "Shanxi Standard" adds two indicators of coke reactivity and post-reaction intensity, which will fully demonstrate the unique competitive advantage of Shanxi coke.
The association took the lead to demonstrate the social responsibility of “Shanxi coke†again. It is understood that the forthcoming “Shanxi standard†is led by the Shanxi Coking Industry Association, which organizes numerous industry experts and coking entrepreneurs, and finally formed after more than two years of business discussions.
With regard to the formulation of the "Shanxi standard," the association official said that this is a responsibility of the association. Coking coal is an important strategic resource of our country and it is directly related to the national energy security and national economic production. At present, China's high-quality coking coal is already scarce. We must consider how to protect China's high-quality coking coal and carry out protective mining. On the one hand, enterprises are encouraged to increase the use of coal blending technology to save the use of coking coal. On the other hand, we must make full use of limited resources to guide the deployment of high-quality resources to outstanding companies and truly realize their value. The association took the lead in the formulation of the "Shanxi Standards," which aims to guide companies to count three books, namely, economic efficiency accounts, social responsibility accounts, and demand accounts for future development. Through the "standard" to promote the optimal allocation of resources, realize the value of resources and achieve the purpose of protecting resources and promoting the sustainable and healthy development of the industry.
