Introduction
Steelmaking furnaces are the key equipment for smelting steel. They serve as an important means for modern steelmaking enterprises to complete their production processes. Therefore, the quality of the steelmaking furnace is an important factor for steelmaking production.
Electric arc furnace
The electric arc furnace is a melting device that uses electric arc power to produce heat. It is suitable for the smelting of low-carbon steel, special steel and so on.
Advantages:
1. It is easy to operate, fast in melting speed and short in smelting time.
2. Its energy consumption is relatively low, and it has a low cost of use.
Disadvantages:
1. When the furnace is operated, the electric arc may cause material evaporation and lead to the loss of alloy elements and refinement ingredients.
2. The use of electric arc furnace is associated with a high safety risk.
Ladle refining furnace
The ladle refining furnace is a steel-smelting auxiliary furnace. It is used in steel refining furnace and is suitable for steel continuous casting. The functions of the ladle refining furnace include deoxidation, degassing, desulfurization and chemical composition adjustment.
Advantages of a Ladle Refining Furnace
1. High work efficiency and low refining cost.
2. It can accurately adjust the chemical composition of molten steel and ensure good quality.
3. It has good desulfurization capability and can reduce the content of sulfur in molten steel to about 0.02%.
Disadvantages of a Ladle Refining Furnace
1. The furnace can only be used for refining steel, not for heating steel.
2. Proper operation is necessary to ensure the accuracy of the measurement value.
Vacuum degassing furnace
The vacuum degassing furnace is a type of steel-smelting auxiliary furnace. It uses vacuum degassing, exhaust gas processing and other physical and chemical methods to purify molten steel and reduce harmful elements such as hydrogen and nitrogen in molten steel.
Advantages of a Vacuum Degassing Furnace
1. High purification efficiency and low energy consumption, the vacuum degassing furnace can reduce the hydrogen content in molten steel by up to 80%.
2. Comprehensively improve the properties of molten steel, reduce casting defects and improve the surface quality of poured steel.
Disadvantages of a Vacuum Degassing Furnace
1. The vacuum degassing furnace is more expensive than other types of furnaces.
2. The operation of the furnace is complicated and requires high technology.
LF and VD electric arc furnace
LF and VD electric arc furnace is a kind of steel making furnace integrating deoxidation, desulfurization and refining. It has the functions of melting steel and refining it.
Advantages of a LF and VD Electric Arc Furnace
1. It is suitable for the smelting and refining of all kinds of steel, and can reduce the refining time of steel.
2. The furnace adopts an intelligent control system, which can reduce the labor intensity of workers and improve work efficiency.
Disadvantages of a LF and VD Electric Arc Furnace
1. The operation and maintenance of the furnace is complex and requires high cost.
2. It has a high investment cost.
Conclusion
Steelmaking furnaces are the key equipment for smelting steel. Different types of steelmaking furnaces have different features and processes, and all have their respective advantages and disadvantages. Steelmaking enterprises should objectively evaluate the suitability of different furnace types and select the furnace that best meets their needs.
