Appliaction of Plasma Technology in Metallurgy
Abstract
In recent years, the use of plasma technology in metallurgy has become more and more extensive. With the expansion of plasma performance and its automatic control, plasma technology has been applied in the fields of metallurgical equipment, metallurgy process monitoring, casting cleaning and so on in many forms, bringing about remarkable economic and social benefits. This paper reviews the applications of plasma technology in metallurgy, and gives a brief introduction to its great potential application prospects.
1. Introduction
Metallurgical industry is an important industry of material production in the national economy, with its unique advantages occupying a pivotal position in the development of urban construction. With the rapid development of science and technology, in order to meet the needs of modern production and the need for modern equipment, plasma technology is increasingly used in metallurgical industry, with remarkable economic and social benefits.
Plasma technology is a kind of advanced technology which uses low-temperature plasma to process materials. In technical terms, it uses high-frequency current or microwave to ionize and excite inert gas, forming a conductive charged medium, plasma. With the application of plasma technology, a variety of physical and chemical effects can be obtained, so as to complete the processing of materials.
2. Applications of plasma technology in metallurgical industry
Nowadays, with the development of plasma technology and its automatic control performance, the use of plasma technology in metallurgy and other fields has become more and more extensive, and various application forms have been constantly revealed.
2.1 Application in metallurgical equipment
Plasma technology can be used in the manufacture of special equipment for metallurgy. For example, plasma cutting machines are widely used in steel production and processing. Plasma cutting is the first step of steel production and processing, and it is very important for selecting raw materials for rolling and cutting after melting. Adopting plasmas cut the steel can save a lot of time and has good cutting effect.
2.2 Application in metallurgy process monitoring
The application of plasma technology in the field of metallurgy is also very extensive. In the monitoring and measurement of metallurgical processes, plasma technology is used to determine the chemical composition of slag or steel in the smelting process,. In addition, it can also be used to control steel parameters such as temperature, oxygen content, slag and so on during the smelting process.
2.3 Application in casting cleaning
In the process of sand casting, it often produces scale, rust, oxide and other residual materials on the surface of the workpiece, which can be removed by the cleaning of plasma technology, so that the appearance of the workpiece is smooth and beautiful. At the same time, the application of plasma cleaning can also improve the forming precision of the workpiece, with good forming effect.
3.Conclusion
Plasma technology has made great achievements in the field of metallurgy. At present, its application in metallurgy has also become more and more extensive. Therefore, it is of great significance to use plasma technology to process and manufacture materials in the metallurgical industry, and its potential application prospects are enormous. In the future, we should continue to pay close attention to the development of plasma technology, and continue to study the application of plasma technology in the field of metallurgy, so as to better promote its application.
