Abstract

The invention discloses a control system for regulating an electromagnetic stirrer in a continuous casting process. The control system comprises a material solidification calculating module and an electromagnetic stirrer positioning module; the material solidification calculating module is configured to determine factors generating influences on the tail solidification end of a casting blank according to received parameters, target data are calculated and obtained according to the factors and sent to the electromagnetic stirrer positioning module, and the parameters comprise the equipment parameters of a continuous casting machine and the work condition parameters of the continuous casting process; the electromagnetic stirrer positioning module comprises a control unit which is electrically connected with the electromagnetic stirrer, and the electromagnetic stirrer positioning module is configured to receive the position of the electromagnetic stirrer and determine or regulate the position of the electromagnetic stirrer according to the target data. According to the control system and method for regulating the electromagnetic stirrer in the continuous casting process, the problem that in the prior art, the purpose of ideal stirring is difficult to achieve caused by the fact that the position of the electromagnetic stirrer cannot be regulated in electromagnetic stirring is solved.

Description

technical field [0001] The invention relates to the technical field of continuous casting process control, in particular to a control system and method for adjusting an electromagnetic stirrer in a continuous casting process. Background technique [0002] Central segregation, central shrinkage cavity and porosity are the main internal defects of continuous casting slab. Electromagnetic stirring technology at the end of solidification can improve the feeding capacity of liquid metal, thereby effectively solving the problem of central shrinkage cavity and improving the quality of continuous casting slab. The solidification end position of the continuous casting slab is affected by parameters such as casting steel type, superheat, casting speed, secondary cooling rate, slab section size, secondary cooling water temperature, and ambient temperature, and changes in real time. Therefore, how to real-time and accurately determine the solidification end position of different slabs ...
