During the production process of steel billet continuous casting, the temperature of precisely controlling steel water has an extremely important role in the quality of the billet and the stability of the entire production line. However, there are always some reasons for the temperature of the steel water. So, during the production process of billet connection, what harm will the temperature of the steel or too low be high or too low? How should we accurately control the temperature of steel water? Today, Luoyang Giant Power will answer these questions for everyone.
The high-temperature steel we often say is very vague. Different people have different understandings of high-temperature steel. Some people think that 1,680°C or 1,690°C, or even 1,700°C are high-temperature steel.
Steel water temperature is part of the process control and serves the production. It has different requirements for the temperature of the steel water at different stages of the process. Therefore, the above limitations of the process temperature requirements can be called high-temperature steel. For example, to improve the efficiency of de-phosphorus in the early stage of the turning furnace smelting, the temperature requirements of the inverted furnace are controlled at 1,610 ~ 1,640°C. More than 10C, it is also high-temperature steel; when the casting machine is poured, it is generally measured by the high-temperature steel with the heat of the middle bag.
High-temperature steel water has a large erosion on the furnace, and after pulling it, it will blow over severe liquid steel. After a few pieces of furnace steel, the furnace supplementation layer or slag splash layer will be exhausted. It will improve the frequency of the furnace and slag, increase the refractory material consumption of the furnace, and the labor intensity of employees.
Excessive steel temperature is easy to cause high steel consumption, high cost, no guarantee of steel water quality, decreased age and endangering serious consequences of safety production.
In the production of steel billet continuous casting, too high or too low steel temperature will cause problems with the quality of the billet, and even affect the efficiency of the entire production line. Therefore, we must strictly control the temperature of steel water to ensure normal production.
