The first million-ton hydrogen-based shaft furnace project in China

In Baosteel shares Zhanjiang Iron and Steel successfully ignited and put into production

This is the largest integrated use of multi-gas source

And eventually use all hydrogen for industrial production.

Production line of direct reduced iron

Marking the transformation of China's steel industry to green and low-carbon

Another exemplary, iconic step

Will further lead the transformation of traditional iron and steel metallurgy process

Baosteel Zhanjiang Iron and Steel's million-ton hydrogen-based shaft furnace will start construction on February 15, 2022. Its main facilities include shaft furnace body, shaft furnace charging and discharging system, product cooling system, gas loop system, raw material input and finished product output system, as well as supporting pellet supply system, energy public auxiliary system and information system. Based on independent integrated innovation, Baosteel Co., Ltd. Zhanjiang Iron and Steel Co., Ltd. has for the first time applied self-developed refractory materials and equipment such as the 112-meter vertical belt conveyor with the highest conveying height in China. The localization rate of the total weight of the project equipment and facilities exceeds 70%, actively promoting the high-end development of domestic manufacturing enterprises. Baosteel Zhanjiang Iron and Steel Co., Ltd. cooperated efficiently with Sinosteel International, Shanghai Baoye and other participating units to continuously overcome difficulties and bottlenecks, ensuring the overall control of project safety, quality and progress. The project was completed and put into production more than 2 months earlier than originally planned, once again showing the "Zhangang speed".

Hydrogen is one of the most promising clean energy

Compared with traditional carbon metallurgy

Hydrogen metallurgy uses hydrogen as fuel and reducing agent

Can make iron out of dependence on fossil energy

Solving the problem of carbon emissions from the source

In the Baowu Carbon Neutral Metallurgy Roadmap

Hydrogen metallurgy process with hydrogen-based shaft furnace as the core

identified as one of the important paths of carbon-neutral metallurgical technology

According to the calculation

After the project is put into operation, the whole process blast furnace ironmaking process before the traditional iron is compared.

Production of molten iron of the same scale

Reduce CO2 emissions by more than 500000 tons per year

Different from the international regular method of using natural gas to prepare reduction process gas, the project adopts the "Hydrogen Metallurgical Electric Smelting Process" (HyRESP), which is the world's first initiative in Baowu. Through the green short process of hydrogen-rich gas purification, hydrogen-based shaft furnace reduction, carbon dioxide capture, direct reduction product cooling, etc, the innovative application of a series of leading technologies such as "direct reduction coke oven gas refining", "flexible process gas allocation" and "cold direct reduction iron product disposal and application" will be formed to accumulate experience for the subsequent independent integration and development of all-hydrogen smelting technology and the formation of low-carbon metallurgical technology with its own intellectual property rights, which is of great significance to the green and low-carbon development of the iron and steel industry.

Green is the life background of the development of iron and steel industry. In recent years, baoshan iron & steel Co., Ltd. Zhanjiang Iron and Steel Co., Ltd. has always cherished the "big one of the country" and has taken the lead in becoming the first iron and steel enterprise in the industry to realize the whole process of "zero discharge of waste water, no delivery of solid waste and ultra-low discharge of waste gas". By improving interface efficiency, applying key energy-saving technologies and optimizing energy systems, the annual energy saving energy of 250000 tons of standard coal is realized, the water consumption industry per ton of steel is the leader in the industry, and has been awarded the "National Energy Efficiency Leader" and "National Water Efficiency Leader" issued by the Ministry of Industry and Information Technology for many years. Actively distribute clean energy such as photovoltaic power generation according to local conditions, and have formed 95MW installed capacity photovoltaic power generation, with a planned annual power generation capacity of 0.15 billion kWh, which can meet the annual power demand of 40000 families. Actively promote the construction of 400MW offshore wind power generation projects and explore new green energy development mode.

Facing the future

Baosteel Co., Ltd. Zhanjiang Iron and Steel

A new starting point will be the ignition and commissioning of the million-ton hydrogen-based shaft furnace.

Actively explore the metallurgical technology of zero carbon production of high grade steel plate

The use of photovoltaic in the South China Sea,

Wind energy forms "light-electricity-hydrogen" "wind-electricity-hydrogen"

green energy system

and through carbon capture, forest carbon sinks, etc.

Realize green hydrogen whole process zero carbon plant

Create a new benchmark for green and low-carbon steel industry
