A series of policies and regulations formulated by our city have laid a solid foundation for energy conservation management. In order to strengthen the supervision and enforcement of energy conservation, the city has carried out special law enforcement supervision and inspection in nine aspects of energy conservation, reporting motor vehicles, energy efficiency labeling, elimination of energy-using equipment and operation of key energy-using equipment for fixed assets investment projects, rectified more than 40 enterprises, investigated and eliminated more than 50 transformers/kloc-0, eliminated more than 200 motors, scrapped more than 60 motor vehicles and more than 800 old high-energy-consuming vehicles. Strictly implement the system of energy evaluation and environmental protection evaluation, and rejected 20 projects with high energy consumption and high pollution that do not conform to the national industrial policy; 227 enterprises such as small mineral processing, small steelmaking, small cement and small paper making were closed according to law; Differential electricity prices have been implemented for more than 90 state-eliminated and restricted high-energy-consuming enterprises that cannot be shut down temporarily. According to the national industrial policy, the cement shaft kiln with an annual output of less than 200,000 tons, the blast furnace with an annual output of less than 300 cubic meters, the papermaking enterprises with an annual output of less than 1 10,000 tons, and the backward steel casting and rolling technology enterprises will be phased out.
In order to vigorously promote new wall materials, our city trained industrial waste concrete perforated brick production enterprises, popularized the product standard of industrial waste concrete perforated brick and the technical specification for industrial waste concrete perforated brick construction, and conducted spot checks on 1 18 projects under construction. The construction units strictly followed the design and construction, basically did not use clay solid bricks, and the application ratio of new wall materials reached over 95%. At the same time, according to the direction of structural adjustment, optimization and upgrading, the city has planned 30 industrial clusters with low energy consumption and less emissions. Through the implementation of industrial cluster projects, the proportion of equipment manufacturing industry has reached 9%, an increase of 3 percentage points over the previous year; The deep processing rate of mineral products reached 40%, an increase of 5 percentage points over the previous year; The on-site processing capacity of steel increased from less than1000000 tons in the previous year to 2 million tons.
Vigorously implement technological transformation and innovation in enterprises, and adopt new energy-saving technologies, new processes, new equipment and new materials. Last year, 20 energy-saving technical transformation projects were implemented, and 900,000 tons of standard coal were saved after the projects were completed. Among them, in order to fully recover and effectively utilize the residual heat in the carbon black tail gas and reduce the pollution of the carbon black tail gas, China Rubber Company invested more than 25 million yuan to build a comprehensive utilization thermal power station and a sewage treatment and reuse device, and recycled more than 420 million standard cubic meters of tail gas in the production process every year to realize the full recycling of wastewater. Liaoning Hengye Group transformed the coal-fired heating furnace into an environment-friendly gas producer at the initial stage of its establishment. In the process of work, no smoke or dust is discharged, which is clean and hygienic. Together with Liaoning Hengye Group, Tianhe Mineral Co., Ltd., Xiyang Group and other enterprises carried out kiln transformation, saving nearly 200,000 tons of standard coal annually.
The GDP of Anshan in 2007 exceeded135 billion yuan. Relying on the central city of Shenyang, we propose to build a new economic uplift zone in Liaoning, focusing on the Anhai Economic Belt, and planning and constructing the Anshan section of the Shenxi Industrial Corridor from a high starting point, so as to make Anshan a new growth pole of Liaoning's economic development.
During the investigation, the Second Steelmaking Plant of Anshan Iron and Steel Co., Ltd. conscientiously implemented the Scientific Outlook on Development, carried out in-depth technological innovation activities, continuously improved the innovation ability of enterprises, and strived to build an innovative steel-making plant. Since the beginning of the year, this factory has established 7 company-level innovation projects, 24 1 factory-level innovation projects, and employees have put forward 864 rationalization suggestions, which effectively promoted the sound and rapid development of the enterprise.
This year, the factory put forward the overall development goal for the next three years of "building an enterprise with high production efficiency, resource conservation and environmental friendliness, and ensuring the sustainable and coordinated development of enterprises". In order to achieve this goal, the factory first carried out "innovation consciousness education", requiring the cadres and workers of the whole factory to enhance their understanding of the importance and urgency of innovation work; Make everyone have a sense of innovation, everyone has a desire for innovation, everyone has innovative projects, and everyone has innovative achievements. On the basis of forming a strong atmosphere of innovation, the factory has grasped the bottleneck problem that restricts production, the core problem related to the quality and grade of varieties, the outstanding problem that affects the function and stability of equipment, and the key problem to achieve the goal of energy saving, emission reduction and cost reduction, and carried out innovative activities extensively.
In order to ensure the in-depth development of innovation activities, the factory set up a technical innovation leading group headed by the main leaders of the factory, revised the management rules and measures of scientific research innovation, and further improved the method requirements and working procedures of innovation work. In the innovation activities, Steelmaking No.1 Work Area put forward "Top-blown converter smelting method for high carbon steel", and adopted effective measures such as slag retention operation, adjustment of oxygen supply intensity and adjustment of iron oxide content in slag at different stages, so that the hit rate of carbon and phosphorus reached 98% and 95% respectively, which were higher than the original smelting method by 2% and1.5%. The "splash-proof" technology of hot metal desulfurization put forward by steelmaking No.1 work area has been successfully applied to production with obvious benefits, and is currently applying for a national patent. In the company-level innovation project "Research on Combined Blowing Long Life Technology of 175-ton Converter", they adopted the method of quickly measuring the bottom of converter, tempered the slag splashing, reduced the slag splashing time and controlled the bottom rise. At present, the bottom blowing life of 1 converter has reached 8 100 heats, which is the best level in Angang.
Through continuous efforts, the plant has successively achieved gratifying results in several key projects and activities, such as RH production guarantee, slab inclusion and reduction of molten iron consumption. The completion and application of the rationalization proposal has created economic benefits of12.35 million yuan, and 10 patents have been accepted by the State Patent Office.
