Tangshan Donghai Steel Group Co., Ltd. is a key steel enterprise in Tangshan City, Hebei Province, a major steel-producing province. Located in Luanzhou City, Tangshan, Hebei Province, it has a steel production capacity of 6 million tons. Established in July 2003, it has a registered capital of 500 million yuan, covers an area of over 4,000 mu, and has fixed assets of over 10 billion yuan. It currently has over 6,000 employees, 40% of whom have a college degree or above. Among them, over 1,080 have junior professional titles or above, over 680 are various intermediate and senior technical personnel, and 35 are senior engineers. Eighty percent of its management personnel have a bachelor's degree or above. The company's annual production capacity is 5 million tons of iron, 6 million tons of steel, and 6 million tons of rolled steel. Its main products include steel billets, hot-rolled medium-wide strip, high-speed high-quality wire rod, and galvanized strip, with an annual output value of over 20 billion yuan.

Main equipment: In the ironmaking process, there are four sintering machines, two pelletizing shaft furnaces, two lime kilns, and eight vertical kilns; in the ironmaking process, there are five blast furnaces; in the steelmaking process, there are three converters and supporting facilities such as desulfurization, dephosphorization furnaces, and refining furnaces; there are three continuous casting machines; in the steel rolling process, there are three hot-rolled medium-width strip production lines and three high-speed high-quality wire rod production lines; in the galvanizing process, there are four pickling lines, five cold rolling lines, and six galvanizing lines; in the energy and power process, there are five supporting oxygen generator units and four supporting generator units.

In terms of environmental protection construction, more than 1 billion yuan was invested in environmental protection projects in 2018, including eight sets of activated carbon flue gas desulfurization and denitrification equipment, six sets of flue gas whitening equipment, and more than 200 sets of electrostatic dust removal and bag dust removal equipment. All environmental protection equipment is fully equipped and can operate stably. All raw materials are stored in enclosed material yards and greenhouses. All raw materials and by-products are transported within the yard without touching the ground, and are transported by new energy vehicles in enclosed containers. At the same time, the company carried out greening, beautification and lighting projects in the factory area, and the green area of the factory area reached more than 30%. Through comprehensive beautification and lighting upgrades, as well as significant investment in environmental protection facilities, the company has now passed the ultra-low emission acceptance by relevant departments and achieved its goal of building a garden-style factory.

In 2015, the company collaborated with Asia Simulation Technology Co., Ltd. to carry out a demonstration project on the integration of informatization and industrialization in steel enterprises, realizing the practical application of simulation control engineering technology in steel enterprises and achieving satisfactory results. In 2017, the National Engineering Research Center for Simulation and Control awarded our company the title of "Research Base for Steel Simulation Based on Big Data". Currently, the first phase of the company's integration of informatization and industrialization project has been basically completed. It has realized a number of practical functions, such as online real-time monitoring and early warning of gas safety system, real-time monitoring and early warning of environmental protection data and emission points, energy dispatch balance and simulation, process connection of production big data platform, and information sharing. It has broken down the company's information silos and laid a solid foundation for the company to achieve high-end intelligent manufacturing.

After nearly a decade of hard work, the group has achieved remarkable results and gained recognition from the government, customers, and banks. It has passed ISO9001 quality management system certification, energy management system certification, occupational health and safety management system certification, and environmental management system certification, and obtained import and export enterprise qualification certificate. In 2006, it became a member unit of the China Iron and Steel Association and a member unit of the Hebei Provincial Metallurgical Association. In 2015, it was awarded the titles of Tangshan City Transformation and Upgrading Demonstration Enterprise and Advanced Unit for Environmental Protection. For many years, the company has focused on enhancing its core competitiveness, adhering to high-standard development goals such as modernizing processes, upgrading equipment, recycling energy, achieving environmental protection and dust removal standards, and optimizing efficiency. It actively adopts advanced and mature processes and equipment from home and abroad, achieving low-cost and high-quality products, and forging a new path for steelmaking characterized by high technological content, good economic benefits, low resource consumption, and ultra-low emissions.
