Shougang iron and steel industry is a modern joint production system from ore to wood. In recent years, Shougang has continuously transformed the steel industry with high technology, making its production technology and technical level always in the leading position in China. Shougang Jingtang Iron and Steel Plant was completed as planned. Qin Shou Company and Qiangang Company were built one after another, and achieved production and efficiency increase in a short time. Shunyi cold rolling project was also completed and put into operation. These projects have created a high starting point, high level and high speed for the construction and development of China iron and steel industry. Shougang has achieved a historic transformation from the production of excellent talents to high-grade plate and fine talents.
Since 2007, Shougang has completed 52 patent applications and obtained 30 national patent authorizations. Actively strengthen superior products, sucker rod steel, alloy welding wire and 82B high-quality wire account for one-third of the national market share. Complete the development of pipeline steel step by step, realize mass production, and become the first enterprise in China to meet the X80 oil pipeline steel technical agreement of the Second West-East Gas Pipeline Project. Promote brand strategy, and initially form a series of brand clusters such as ship plate, pipeline steel, cold heading steel, corrosion-resistant plate, high-strength mechanical plate and high-rise building plate. Shougang brand high-quality carbon steel hot-rolled wire rod won the title of China famous brand product, and the rebar rod passed the inspection-free export audit of AQSIQ.
Shougang is the largest wire rod production base in China. In recent years, the technological level of steel rolling system has been continuously improved by using high-tech to transform equipment. Among them, the project "Development and Innovation of High-speed Wire Rod Production" won the first prize of national scientific and technological progress. Shougang iron and steel products cover plates, pipes, profiles, belts, wires and wires, and have passed the IS09002 quality system certification as a whole. The physical quality of wire rod and thread, the leading product, has reached the international advanced level, and the ship plate has passed the certification of China, the United States, Britain, Germany and Norway. Hot-rolled ribbed steel bars for concrete, torsion-free controlled cooling low-carbon steel hot-rolled wire rods, steel plates for hull structure, etc. , won the national "Gold Cup Award for Physical Quality of Metallurgical Products". Shougang Steel is widely used in Beijing Subway, Beijing West Railway Station, New Terminal Building of Capital Airport, Three Gorges Water Control Project, Nanjing Second Yangtze River Bridge, Shanghai Yangpu Bridge, Gezhouba, Xiaolangdi of the Yellow River and other national key construction projects.
