According to the analysis of China's restored iron powder industry, with the continuous improvement and expansion of the use of iron powder, there are higher requirements for the quality of restored iron powder. To meet this request, in 1946, hydrogen secondary refined restoration treatment was added in the process, which greatly broke through the improvement of the chemical purity of iron powder and the physical and metallurgical properties of iron powder. As a result, the C content of iron powder was lower than 0.01%, and the hydrogen loss value was reduced to about 0.12%, The tightness reaches 6.8g/cm3. We are currently analyzing the trend of China's iron powder industry recovery in 2017. At this point, the world's most advanced and mature carbon hydrogen two-step method for directly recovering iron powder consumption has preliminarily formed. Metallic chromium powder

Since the 1950s, with the exploration and summary of the consumption theory of restored iron powder from time to time, the use of advanced restoration equipment, tunnel kilns, has gradually replaced the original circular pit kilns. This is a significant progress in the restoration process and energy consumption, and there have also been modifications in the loading method. Firstly, through flat layer installation, vertical layer installation, and ring installation, the heat transfer efficiency of the material layer has been greatly improved during the restoration process, This causes the material layer to recover more thoroughly, reduces the phenomenon of entrapment, and significantly increases the total iron content of the product. Subsequently, the columnar method was used, which greatly saved the recovery process and improved the physical, chemical, and metallurgical properties of the recovered iron powder, further expanding its usefulness.

Many foreign consumer manufacturers are more concerned about this point. Sweden's Hergnard Company once stopped technological transformation, reduced the content of impurities SiO in ultra-pure iron concentrate powder, and improved the quality of iron powder; Lengthen the kiln body, expand the range, and increase production. In order to expand its consumption range of recovered iron powder, Kawasaki Iron Corporation of Japan purchased sponge iron intermediate products consumed by iron concentrate powder from China as early as 1985. In addition, Sulin Metallurgical Plant of Russia, Western Europe, and some countries in North America have started to consume recovered iron powder from magnetite concentrate powder. In these countries, the consumption of recovered iron powder from high-purity iron concentrate powder accounts for 80-90% of the annual iron powder production.

The market research and analysis report on the iron powder industry shows that for a company, a central development content is necessary and a physical pillar for sustainable development. Only in this way can its value be demonstrated. If a company's brand is well established, intangible assets will correspondingly increase, greatly enhancing the added value of its products.

From this perspective, when carrying out the restoration of iron powder manufacturers in China, it is necessary to pay attention to the strength of forming a brand, mainly focusing on quality, management, and service, emphasizing the extension of products and additional products, and occasionally stopping promotion

Renovation, regular follow-up visits to users, timely understanding of their consumption needs, in order to produce the best products that fit the market.
