The Reasons for Control of Steel Liquid Level in Ladle
Introduction
Ladle is an important component in the steel making process. As an important container used for refining, transporting and desulfurizing liquid steel, its performance directly affects the production efficiency and product quality of the steel plant. Steel liquid level in a ladle is one of the most important operating parameters to control. The steel liquid level in ladle should be monitored, measured and controlled in the steel making process. In this paper, the importance of controlling steel liquid level in ladle, the reasons for controlling steel liquid level in ladle, and the precautions for controlling steel liquid level in ladle are discussed in details.
Importance of Controlling Steel Liquid Level in Ladle
Controlling steel liquid level in a ladle requires accurate and careful control. The control accuracy and operating level of the steelmaking process crucial relies on the control level and operating level of the liquid steel in a ladle. Uncontrolled steel liquid level in a ladle will not only lead to the overfilling of a ladle, but also cause the coking of steel liquid in a ladle due to improper slag-water balance. Moreover, uncontrolled steel liquid level in a ladle also affects the desulphurization of a ladle and the performance of slag-forming compounds, which ultimately affects the forming quality, structure and properties of the produced steel products.
Reasons for Controlling Steel Liquid Level in Ladle
(1) Unstable liquid steel level in the ladle affects the usage of the ladle. Improper liquid steel level will cause liquid steel overfilling of the ladle, water leakage or water accumulation, resulting in unsafe operation.
(2) Improper liquid steel level in the ladle affects the slag-water balance and will lead to the coking of the steel liquid, which will degrade the performance of the steelmaking process and the quality of the steel product.
(3) Improper liquid steel level will also affect the desulfurization efficiency of the ladle, resulting in insufficient desulfurization of the produced steel.
(4) Uncontrolled liquid steel level will also affect the performance of slag-forming components, and poor slag-forming performance will have an adverse effect on the quality and structure of the steel products.
Precautions for Controlling Steel Liquid Level in Ladle
In order to ensure the normal operation of the steelmaking process and the production of high-quality steel products, it is necessary to take measures for the control of steel liquid level in the ladle.
(1) The steel Refining Operation Standard must be strictly complied with. It is necessary to formulate a refilling standard for the steel liquid level of a ladle based on the quality and deformation requirements of the steel product.
(2) The adjustment and control of the steel liquid level in the ladle should be carried out in stages and layer by layer. Sometimes the slag should be first added or some liquid steel should be added to the ladle to adjust the liquid steel level.
(3) The adjustment of the steel liquid level in the ladle should be timely tracked and monitored. The steel liquid level should be checked every 10 minutes and readjusted if necessary.
Conclusion
Controlling the steel liquid level of a ladle is very important for the quality and production efficiency of steel products. The steel liquid level in the ladle must be adjusted and controlled according to the requirements of the production process. Standard operating procedures should be established to ensure that the steel liquid level in the ladle is precisely controlled in the steelmaking process.
