Rizhao Steel Holding Group Co., Ltd. (hereinafter referred to as Nickel Steel Group) was established in 2003 and reached a crude steel production capacity of 10 million tons in 2008, and its output value exceeded 100 billion yuan in 2019. Currently, it has a steelmaking capacity of 18.95 million tons. It is an important high-quality thin and broadband steel production base. It is the president unit of Shandong Iron and Steel Industry Association and the main enterprise of Shandong Iron and Steel Industry Chain. Its main products include hot-rolled thin plates and hot-rolled Rolling plate, cold forming plate, pickled thin plate, galvanized thin plate, high-strength H-shaped steel, etc.

In recent years, Niss Steel Group has the vision of "building a globally competitive specialty plate manufacturing base", adheres to the purpose of "promoting industry development, creating customer value, and fulfilling social responsibilities", adheres to the core leading role of scientific and technological innovation, and continues to promote the new and old. The transformation of kinetic energy and digital transformation continue to make efforts in high-end, intelligent and green, laying a solid foundation for cultivating and developing new quality productivity. During the 13th Five-Year Plan period, Nippon Steel Group produced a total of 70.45 million tons of steel, achieved operating income of 354.6 billion yuan, net profit of 35.5 billion yuan, and paid 32.1 billion yuan in taxes (including 12.1 billion yuan in customs duties).

High-end. Niss Steel Group has invested more than 50 billion yuan to carry out industrial upgrading and transformation, and has built 5 international advanced ESP production lines, accompanied by 9 pickling, galvanizing and leveling production lines. It is currently the world's largest ESP production base. "ESP technology integration and innovation And application "Scientific and technological achievements have reached the international advanced level, and many other indicators such as ESP thin specification rolling have maintained world records. The output of ESP's special products exceeds the province's steel output by 10%, and the market share of weather-resistant steel for containers is relatively high. Niss Steel Group actively undertakes the urban steel production capacity of 9.62 million tons, builds 3 3,000 cubic meters blast furnaces, 3 300 tons converters and supporting auxiliary facilities, saving 60% of land compared with the original, reducing pollution by more than 60%, and reducing energy consumption by 25%. More than % will focus on developing green products such as "hot instead of cold" series of steel, high-strength thinning automotive steel. Nikko Group accelerates the promotion of restricted equipment "to increase large pressure small pressure, increase new pressure old pressure, increase high pressure low pressure", vigorously promote large-scale equipment renewal, forming 3,000 cubic meters of blast furnace and 300-ton converter as the main body, and realize that all equipment is large The main processes and technologies have reached the international advanced level.

Intelligent. Nikko Group has accelerated the intelligent and digital transformation of the industry, and has built an integrated integrated information management system including procurement, sales, production, finance, logistics management and control, human resources, engineering projects, collaborative office, etc., with core software and hardware technology patents. 13 projects have been developed and integrated with more than 30 industrial APPs, realizing full-process automated management and control, improving the level of flexible production and manufacturing, and 100% accuracy of full-process order tracking. Five ESP production lines have been built with "digital workshops" and "smart factories". A single production line is equipped with more than 1,500 data acquisition sensors, detection instruments, etc., and data is collected 100% automatically. Nikko Group applies advanced technologies such as artificial intelligence, machine vision, big data algorithms, etc. to accelerate the creation of a large 20 million ton full-process intelligent manufacturing demonstration factory, and after completion, it realizes "equipment automation, business informationization, and service network in the whole process. Intelligent operation.”
