What is metallurgy? Classification and role of metallurgy industry

What is metallurgy?

Metallurgy is the scientific and technical field and industry of preparing metals from ores or other raw materials, processing alloys, processing metal ingots by pressure, by changing chemical compositions. learn and structure to create properties suitable for use requirements.

Classification and role of metallurgy industry

1. Black metallurgy industry

- Ferrous metallurgy is one of the most important branches of heavy industry. Its main products are cast iron and steel, the basic raw materials for the mechanical and metalworking industries to create means of production, working tools, complete equipment and even consumer goods. The ferrous metallurgy industry also provides iron-steel components for the construction industry

- Almost all economic sectors use products of ferrous metallurgy industry. Ferrous metals account for about 90% of all metal production in the world. It is its popularity in production and life that has increased the importance of this industry.

2. Non-ferrous metallurgy industry

Non-ferrous metallurgy industry consists of mining and ore-enriching enterprises, producing alloy non-ferrous metals and processing them into products. These are non-ferrous metals (such as copper, aluminum, tin, lead, zinc, gold...), many of which are of strategic value. Non-ferrous metals are classified into 4 main groups as basic non-ferrous metals, alloy non-ferrous metals, precious non-ferrous metals and rare non-ferrous metals.

Non-ferrous metals are widely used in the machine-building industry, especially in the manufacture of automobiles, aircraft, electrical engineering, electronics, chemical industry, and also in many other national economic sectors such as post and telecommunications. communication, commercial...

The main job of a person working in metallurgy

The jobs of metallurgists are diverse and specialize in different fields. You can be a researcher, metallurgical engineer, technician or manager, consultant and technology transferee, etc.

Collectively, however, metallurgists will be involved in one or more of the following jobs:

- Design plant and metallurgical equipment

- Set up technological processes and operate those processes to produce metals and alloys such as: cast iron, steel, copper, aluminum, gold, silver, ferroalloys...

- Research non-coke metallurgy technology and new technologies for the future.

- Shaping metal materials: steel plates, profiles, bars, machine details, monuments, large monolithic details in the manufacture of ships, aircraft...

- Change the structure and properties as required.

- Research and apply advanced and modern metallurgical technologies and equipment.

 Research on modeling of metallurgical processes

- Control metallurgical processes by computer program.

- Research on metallurgical properties and optimal use of natural resources.

- Research refining, alloying and heat treatment to produce ultra-clean, ultra-fine and ultra-strong metal.

- Research and manufacture special alloys and specialized alloys: Heat-resistant, corrosion-resistant, wear-resistant, impact-resistant, high-load-bearing, high-magnetic and non-magnetic, thermally, electrically conductive and other thermal, electrical insulation, benign for medical purposes, anti-vibration before oscillation, image memory for high technology...

- Research on waste treatment and environmental protection technologies
