Description

Technical Field

[0001] The invention relates to the technical field of cooling water monitoring, in particular to a metallurgical furnace cooling water monitoring system. Background Art

[0002] Metallurgical furnaces refer to equipment used for metallurgical processes such as smelting, sintering, melting, reduction, and melting, and are an important part of the metallurgical industry.

[0003] During the operation of metallurgical furnaces, cooling water is often required for cooling. Metallurgical furnaces work in high temperature environments. If they are not cooled, the steel structure and refractory materials of the furnace body will deform, soften or even melt due to overheating. Taking the steelmaking converter as an example, its furnace shell is usually made of steel plates. During the blowing process, the temperature inside the furnace is as high as over 1600°C. If there is no cooling water to cool the furnace shell, the steel plate of the furnace shell will quickly lose its strength due to the high temperature, causing damage to the furnace structure. Therefore, existing metallurgical furnaces need to be equipped with a good cooling water cooling system to cool them down, and they also need to be equipped with a corresponding cooling water monitoring system to prevent problems during the cooling of the cooling water circulation, which will cause damage to the metallurgical furnace and cause incalculable consequences.

[0004] The existing cooling water monitoring system needs to monitor the cooling water pressure and water temperature. In the process of monitoring the cooling water temperature, a thermal resistance thermometer is often used to monitor the cooling water temperature. However, during the long-term use of the thermometer, the hardness ions such as calcium and magnesium contained in the cooling water will, under certain conditions, combine with anions such as carbonate and sulfate in the water to form insoluble salts such as calcium carbonate and calcium sulfate. When the water temperature of the cooling water increases, the solubility of calcium carbonate will decrease, and it will easily precipitate from the water to form a precipitate, which will adhere to the thermometer, affecting the thermometer's monitoring of the cooling water temperature and resulting in inaccurate monitoring data.

[0005] Based on this, a metallurgical furnace cooling water monitoring system is now provided, which can eliminate the disadvantages of the existing devices. Summary of the invention
