The continuous casting process is actually a solidification heat transfer process from high-temperature molten steel to solid state, and the solidification heat transfer process of the casting blank plays a crucial role in the quality of surface cracks, internal cracks, bulging and the like of the casting blank. In the process of solidification and heat transfer of the casting blank, water is mostly sprayed to the surface of the casting blank for secondary cooling. Therefore, in the continuous casting production process, secondary cooling water plays a crucial role in quality control of the casting blank, wherein the water distribution amount of each cooling section has a reasonable proportioning range, otherwise, the temperature return of the casting blank is caused, or the internal quality problem of the casting blank is caused due to over-strong cooling. Therefore, the quality of the casting blank is effectively improved by ensuring that the secondary cooling water amount is always within the range of the set value in the production process.
At present, in the continuous casting production, secondary cooling water distribution adopts a secondary water distribution curve related to the pulling speed, wherein the secondary water quantity of each section Q = aV2+ bV + C. And the minimum value is the minimum requirement for meeting the water atomization of the section of the spray pipe in the setting process. In the current production process, as long as the section has no secondary cold water in the production process, the flash of the secondary cold water quantity of the section on the computer control interface can occur.
