1. Professional overview:
Metallurgical engineering majors mainly focus on the refining, processing and application of metal materials. This includes extracting metal elements from ores, transforming metal materials into products by physical and chemical methods, and developing new metal materials and technologies to improve the performance of existing metal materials.
2. Metal material refining:
Metallurgical engineers study how to extract metal elements from ores. First of all, they need to analyze and evaluate the ore to determine which metal elements are contained in the ore and how to extract them. Common refining methods include ore crushing, leaching, redox and so on.
3. Metal material processing:
Metallurgical engineers study the processing technology of metal materials in order to convert them into forms that can be used to make products. The machining process includes forging, rolling, casting, welding and so on. , aiming at changing the shape, size, structure and performance of materials. They need to consider the deformation and loss of materials during processing, and how to control the parameters such as temperature and pressure during processing.
4. Metal material application:
Metallurgical engineers pay attention to the application of metal materials in different fields. They study the properties of metal materials to determine which products and fields they are suitable for. For example, metal materials are widely used in aerospace, automobile manufacturing, building structures, electronic equipment and other fields. Metallurgical engineers also need to study how to improve the properties of metal materials and improve their strength, hardness and corrosion resistance.
5. Research and development of new metal materials;
Metallurgical engineers are committed to developing new metal materials to meet the needs of modern industry for special properties such as high strength, light weight, high temperature resistance and corrosion resistance. By changing alloy composition, adjusting crystal structure and introducing nanotechnology, they developed metal materials with excellent performance.
6. Resource conservation and environmental protection:
Metallurgical engineering also pays attention to the rational utilization of resources and environmental protection. In the process of refining, processing and application of metal materials, metallurgical engineers need to consider how to reduce energy consumption, reduce waste water and waste gas emissions, recycle waste and realize sustainable development.
