The upstream of cold heading steel industry chain is mainly composed of iron ore, scrap steel, alloy and other raw materials. The middle reaches is the production link of cold heading steel. Cold heading steel must have good cold heading performance, reduce the content of impurities such as S and P in steel, have strict requirements on the surface quality of steel, and often use high-quality carbon steel. If the carbon steel content of steel is more than 0.25, spheroidizing annealing heat treatment should be carried out to improve the cold heading performance of steel. Downstream deep processing products of cold heading steel include high-strength standard parts and automotive, electrical and mechanical connectors and fasteners such as bolts, nuts and screws. The future development trend of China's cold heading steel industry may be manifested in environmental protection requirements and industrial upgrading, demand growth and product upgrading, technological innovation and R & D investment. In this process, cold heading steel enterprises need to pay close attention to market dynamics and consumer demand, and constantly carry out product innovation and market expansion to adapt to the trend of industry development and enhance their competitiveness. Green development: Under the background of increasingly strict environmental protection policies, green development has become an inevitable trend in the cold heading steel industry. The sustainable development of cold heading steel industry is promoted by means of energy saving, emission reduction and resource recycling. Intelligent production: With the advancement of industrial 4.0, intelligent production will become an important development direction of the cold heading steel industry. Through the introduction of Internet of Things, big data, artificial intelligence and other technologies, the automation, informatization and intelligence of the production process are realized, and the production efficiency and product quality are improved. 3. high quality products: With the improvement of product quality requirements in downstream industries, high quality cold heading steel will become the main demand of the market. By improving product quality and performance, enhance the added value of products and market competitiveness. Innovation and R & D: Strengthening innovation and R & D is the key to the development of cold heading steel industry. Through technical research and independent research and development, break through key core technologies, improve independent innovation capabilities, and promote scientific and technological progress in the cold heading steel industry. 5. Expand application fields: actively expand emerging application fields, such as new energy, electric vehicles, high-end equipment manufacturing, etc., to provide new impetus for the development of cold heading steel industry. At the same time, the development of high-performance cold heading steel products suitable for emerging fields to meet market demand.
