Introduce

Steel structures are used extensively in the metallurgical industry and play an important role in energy conversion, transportation, construction, communications, health, safety and infrastructure. Steel structures are often used in combination with other functional properties such as corrosion resistance, thermal and electrical conductivity, and magnetism due to their superior strength, hardness, machinability, damage resistance, connectability, ductility and toughness. These properties make metals a key material for building social infrastructure and products, such as agricultural tools, manufacturing machinery, energy conversion engines, and reinforcement materials in large concrete infrastructure.

Metallurgical Steel Structure Types

Metallurgical Steel Structure Features

High Strength

Steel structures are known for their high strength, which allows them to support heavy loads and resist various stresses and strains.

Durability

Steel structures are very durable and can be used in harsh environmental conditions, including extreme temperatures and corrosive environments.

Machinability

Steel can be cast, rolled, cut and welded into a variety of shapes and sizes to suit different design and engineering needs.

Toughness

Steel structures have good toughness, which means they can absorb energy without breaking when they are hit or overloaded.

Connectability

Steel structures can be easily connected by welding, bolting or riveting, which facilitates the assembly and maintenance of the structure.

Corrosion Resistance

Steel structures can have good corrosion resistance by using specific alloying elements (such as nickel, chromium) or coatings (such as galvanizing).

Thermal And Electrical Conductivity

Some steel structures have good thermal and electrical conductivity, which makes them very useful in applications that require heat or electricity conduction.

Magnetism

Steel structures can be magnetic, which is very useful in applications that require magnetic forces, such as in motors or generators.

Recyclability

Steel structures are recyclable, meaning they can be recovered and reused at the end of their useful life, reducing waste and having a lower impact on the environment.

Cost-effectiveness

Although the price of steel can vary due to market fluctuations, overall, steel structures offer a good cost-effectiveness ratio, especially when considering their strength and durability.

Design Flexibility

Steel structures allow designers greater flexibility to create buildings and structures of various shapes and styles.

Fast Construction

The components of steel structures are often prefabricated in a factory, which means they can be quickly assembled on site, reducing construction time.

Low Maintenance Costs

Steel structures generally require less maintenance because they are not susceptible to rot or insect infestation and can be protected with coatings or paint.

Environmental Impact

Although there is a certain environmental impact during the production of steel, these impacts can be reduced through the use of renewable energy and improved production processes.

Metallurgical Steel Structure Application

Application 01
Oil And Gas Pipelines

In the oil and gas industry, steel structures are mainly used for long-distance oil and gas pipelines. These pipelines need to have high strength, good toughness and weldability to ensure safe operation under different environmental conditions. For example, in the history of China's oil and gas pipeline development, the application of microalloying and thermomechanical control process (TMCP) technology has achieved an excellent match of pipeline steel in strength, toughness, plasticity and weldability to meet the strong demand for domestic energy consumption.
Application 02
Metallurgical Industry

In the metallurgical industry, steel structures are used to build various industrial facilities such as blast furnaces, steelmaking furnaces and rolling mills. These structures need to withstand extreme temperatures and heavy loads. For example, the use of steel structures in bridges and buildings requires the use of steel plates, which are produced in domestic electric arc furnaces and basic oxygen furnaces. The weighted average recycled content of steel plates used for construction applications is 75%.
Application 03
Petrochemical Industry

In the petrochemical industry, steel structures are often used for pipe racks and non-building structures, such as pipe racks in oil and chemical plants. These structures need to have seismic resistance to ensure safety in the event of natural disasters such as earthquakes. For example, a critical assessment of existing design specifications for petrochemical steel pipe racks was conducted, and case studies were conducted to ensure the safety of these structures in high seismic risk areas.
Application 04
Building Structures

Steel structures are also very common in the construction industry. They can be used to build high-rise office buildings, residential buildings, bridges, and other large structures. Steel structures are favored for their excellent load-bearing capacity, flexibility, and long-term durability. For example, steel structures have a market share of 46% in non-residential and multi-story residential construction, which is significantly higher than other competing materials.
