Metallurgy refers to the process and technology of extracting metals or metal compounds from minerals and transforming metals into metal materials with certain properties through various processing methods. Metallurgy has a long history of development, from the Stone Age to the subsequent Bronze Age, and then to the large-scale development of modern steel smelting. The history of human development is integrated with the development history of metallurgy.
Category Metallurgical industryThe equipment mainly used in the metallurgical industry includes the following types :
1. Smelting equipment :
* Blast furnace : Used for iron smelting, the blast furnace body consists of the throat, the body, the waist, the belly and the hearth, and pig iron is obtained by reducing iron ore at high temperature.
* Converter : Used for steelmaking, it removes impurities and adjusts composition by adding scrap steel and oxygen for oxidation reaction.
* Electric furnace : For steelmaking, it uses electric energy to melt scrap steel and add materials. It is suitable for small-batch production and the production of special steel.
* Reverberatory furnace : Used for smelting non-ferrous metals such as lead and zinc, it generates high temperature by burning fuel and is suitable for large-scale industrial production of .
2. Continuous casting equipment :
* Continuous casting machine : Used to rapidly solidify molten metal liquid into initially formed castings, improving production efficiency and product quality .
3. Rolling equipment :
* Rolling equipment : including cold and hot rolling mills for plates, tubes, sections and wires, for the forming and processing of metal materials .
4. Lifting equipment :
* Metallurgical cranes : such as foundry cranes, used for lifting molten metal in high temperature and high dust environments to ensure production safety and high efficiency.
5. Environmental protection equipment :
* Flue gas purification device : Used to treat the flue gas and dust generated during the smelting process, reducing environmental pollution .
* Online leakage monitoring device : Used to detect the safety status of electrical equipment and prevent safety accidents caused by leakage .
These devices each play an important role in the metallurgical industry, jointly ensuring an efficient, safe and environmentally friendly production process.
