The significance for blast furnace ironmaking is to replace coke with coal, reduce the coke ratio, save the investment and energy consumption of coke production, and ease The contradiction of the lack of main coking coal; at the same time, it can improve the smelting operation of the blast furnace and promote the steadily moving blast furnace. The smelting strength is a strengthening index based on the volume utilization coefficient. The price is low, the specifications are complete, the quality is excellent, the size can be customized and supplied in a timely manner, welcome to come to order by letter. Optimization of sintering ore mix structure With the development of my country’s iron and steel industry, domestic iron ore resources are increasingly scarce, there are many types of imported ore domestic mines, and prices and qualities vary. With the shortage of anthracite resources for traditional injection and high prices, bituminous coal injection technology with high volatility and strong explosives has developed rapidly, and more and more blast furnaces have begun to inject bituminous coal, lignite and other coal types.
Optimization of coke coal blending structure The role of coke in blast furnace smelting is the charge skeleton, reducing agent, heating agent and carburization. Baoding Daqian Equipment Technology Co. To a certain extent, it misleads people to adopt the extensive operation method. Optimization of injection coal structure The blast furnace coal injection technology has become a widely adopted technical measure for modern blast furnace ironmaking production to save coke and increase iron, reduce costs and increase efficiency, improve the smelting process and promote the blast furnace to go forward. Stable and reasonable operating system, optimizing blast furnace operation index parameters, maintaining blast furnace rational operation furnace type, maintaining blast furnace stability and direct operation, and improving blast furnace technical and economic indicators to achieve the technical policy of modern blast furnace "high efficiency, high quality, low consumption, long life, environmental protection" . Optimization of blast furnace operation index parameters Today, with the increasingly advanced blast furnace ironmaking process technology and equipment level, blast furnace operators use advanced technology such as oxygen-rich, high pressure, coal injection and high air temperature to machining bushing adjust based on concentrate technology.
Scientific and technological means must be reflected by technological progress and technological innovation. 2.), maintain the volume of furnace gas suitable for the smelting conditions, achieve high efficiency of the blast furnace, maintain an economical pulverized coal ratio suitable for the smelting conditions, and achieve the purpose of improving the replacement ratio and reducing the fuel ratio. Practice shows that it has a U-shaped curve relationship with the coke ratio (or fuel ratio), and the lowest point of the curve corresponds to the appropriate smelting strength at the lowest coke ratio , Increasing or decreasing the smelting intensity will increase the coke ratio. It measures the strengthening degree of the blast furnace based on the volumetric combustion intensity. The practice of Baosteel’s blast furnace to reduce the amount of gas per ton of iron furnace to achieve strengthening shows that reducing fuel is the most effective way to reduce costs and increase efficiency. mainly produces Langyashan brand casting filters, molten steel filters, molten iron filters, copper filters, aluminum filters, silicon carbide ceramic filters, zirconia ceramic filters, alumina ceramics Filter, special aluminum alloy filter, casting filter production equipment, etc.
