Why is steel still the most important, versatile and adaptable engineering material?
1. The application of steel materials has mature experience in all aspects of daily life, and its scope is irreplaceable.
2. The cheap characteristics of steel materials are incomparable with other materials.
3. The plasticity of steel materials is beyond the reach of other materials.
4. The earth is rich in iron. The composition of steel can be recycled by recycling its products, and other materials cannot be copied.
5. The maturity of smelting technology and standardization of products will be difficult in the near future.

The importance of iron and steel industry to the country
1, status: Steel is known as industrial grain. It is the most widely used metal material for human beings, with high strength, good mechanical properties, abundant resources and low cost. It is suitable for mass production, widely used in all fields of social production and life, and is an indispensable strategic basic industrial product.
Almost all industrial processes in industrialized countries started in iron and steel smelting. Without steel, there would be no other industrial products, no tall buildings, no guns, cars and boats. In the national economy, the steel industry, like the mother of all industries, directly determines the industrialization foundation of the whole country.
Even in developed countries that have experienced industrialization and are developing towards new industrialization, the steel industry, especially the high-end steel industry, is still an irreplaceable important industry.
2. Features:
The main characteristics of iron and steel industry are large-scale, high energy consumption and high pollution. The main raw materials of steel are coal and iron ore. The greater the steel output, the greater the consumption of these two resources, and the only way to ensure that the production cost is low enough is to expand the scale.
At present, large-scale iron and steel joint ventures concentrate all aspects of production together, coking, sintering, ironmaking, steelmaking and steel rolling are interlocking, raw materials enter from one end, and the final products are exported from the other end. Large-scale and high-efficiency management has become the main feature of iron and steel industry.
In many places, a steel enterprise can support a city. Today, raw materials for steel enterprises come from all over the world. Ore from Brazil on one side of the globe will be transported to the other side to meet the production demand of China. The high internationalization of the steel industry is also a major feature. The iron and steel industry consumes a lot of coal, water and electricity, and the energy consumption of its industrial operation is amazing, and its pollution is equally amazing.
Although the steel industry has achieved clean production through continuous technological transformation, the smoky production environment in the past has been greatly improved, and various waste residues in the steel industry can be recycled, the steel industry is still an important source of greenhouse gas emissions, and its pressure on the environment can never be eradicated. Steel not only creates great wealth for mankind, but also destroys the human environment.
