New version of steel development guidance or the end of the year

New version of steel development guidance or the end of the year

The reporter of "Economic Information Daily" learned that relevant departments in my country are studying the guidance for the development of the steel industry in the new stage. The guidance will be led by the National Development and Reform Commission, the Ministry of Industry and Information Technology and other departments, with the cooperation of relevant associations, and is expected to be issued as soon as the end of this year. According to authoritative sources, on the one hand, the overall economic structure has been adjusted, and on the other hand, changes in crude steel production capacity have prompted changes in the contradiction between supply and demand in the industry. Therefore, it is urgent to study the future development direction of the steel industry under the new economic environment. Zhang Zhixiang, president of the All-Union Metallurgical Chamber of Commerce, said that with the continued reduction of 30 million tons of production capacity this year, the steel industry will complete the previous "Steel" ahead of schedule.

How big is the particle size of reduced iron powder to create higher economic benefits

The main uses of reduced iron powder are: powder metallurgy products reduced iron powder, this industry consumes 60% to 80% of the total amount of reduced iron powder. The reduced iron powder for welding electrode, adding 10 ~ 70% iron powder to the coating can improve the welding process of the electrode and significantly improve the deposition efficiency. Reduced iron powder for chemical industry, mainly used for chemical catalyst, precious metal reduction, alloy addition, copper replacement, etc. Cutting stainless steel iron powder, when cutting steel products, spraying iron powder into the oxygen-acetylene flame can improve the cutting performance, expand the scope of cutting steel, and increase the thickness of cutting. China's powder metallurgy industry technology continues to improve, the current powder metallurgy parts should be widely used.

The heat treatment process must reach these eight realms!

1, divided into two: different materials, different equipment, different process parameters, heat treatment after the organization and quality are also different. Even if the material grade, equipment, process parameters are the same, due to the chemical composition content of the upper and lower limits, heat treatment temperature upper and lower limits, holding time upper and lower limits are different, the organization and quality after heat treatment will be different. Even if the upper and lower limits of chemical composition content, the upper and lower limits of heat treatment temperature and the upper and lower limits of holding time are the same, the organization and quality after heat treatment will also be different due to the different processes, quality and organization of cold and hot processing in the early stage of heat treatment. Therefore, after the problem to specific problems specific analysis, that is, to be divided into two

Robot industry development faces historic opportunities

At present, it has become a common challenge for all countries to realize the continuous transformation of new and old kinetic energy and promote strong and sustainable economic growth. At the Skilled Talents and China Manufacturing Summit Forum held a few days ago, Luo Junjie, deputy director of the Equipment Industry Department of the Ministry of Industry and Information Technology, pointed out that in recent years, my country's economy has entered a new normal, and the development of intelligent manufacturing is to realize the cultivation and development of emerging industries and traditional industries. The best way to organically combine transformation and upgrading. In the next step, we will further implement the special project of intelligent manufacturing, continue to promote pilot demonstration, speed up the revision and popularization and application of standards, actively cultivate system solution suppliers, deepen international cooperation, and improve intelligent manufacturing.

Desulfurization treatment of castings

The fly-up desulfurization process by primary dust removal adopts double alkali flue gas desulfurization process, which has fast desulfurization reaction speed and high desulfurization efficiency. The double alkali flue gas desulfurization process is a deformation of the limestone (lime)/gypsum washing method, which overcomes the shortcomings of the limestone/lime method that is easy to scale and improves the SO2 removal rate. Therefore, the "double alkali method" process is selected for this scheme. The double alkali method is an important process in the wet process, which has the characteristics of high desulfurization and dust removal efficiency, low investment, small land occupation and low operating cost, which is very suitable for China's national conditions. Desulfurization is the use of sulfur dioxide characteristics, namely, acidic, solubility, oxidation, reduction. And after sulfur dioxide is dissolved in water
