Problems solved by technology

[0003] In order to optimize the secondary cooling control, many control devices based on the secondary cooling heat transfer mathematical model to simulate the continuous casting process and calculate the distribution of secondary cooling water have been developed in recent years. They have improved the continuous casting operation to a certain extent. However, due to their mathematical The model can only simulate the stable pouring process off-line, but cannot reliably reflect the actual continuous casting process with frequent changes in casting conditions, so the control accuracy is not ideal

Description

technical field [0001] The invention belongs to metallurgical production control equipment, in particular to a cooling control equipment for continuous casting slab production. Background technique [0002] In the metallurgical production process, the secondary cooling of continuous casting directly affects the quality of slab and the output of continuous casting machine. On the one hand, the secondary cooling control is related to the occurrence of cracks and other defects in the continuous casting slab. In order to ensure the production of high-quality continuous casting slab, it must be based on parameters such as steel type, pouring temperature, casting speed, slab size and caster size. To formulate the corresponding cooling process; on the other hand, reasonable control of the length of the liquid phase cavity can optimize the casting speed and increase the output of the continuous casting machine. [0003] In order to optimize the secondary cooling control, many contr...
