The invention provides a monitoring system and a monitoring method for cutting length abnormity of cast blanks. The monitoring method comprises: by a cutting length acquiring module, acquiring and recording the detected length of the cast blanks cut from each flow from a fixed-length cutting device of each flow; through a cast blank weight acquiring module, acquiring and recording the detected weight of the cast blanks of each flow from a cast blank weighing device of each flow; through a cast blank weight-per-meter calculating module, automatically calculating the weight per meter of the cast blanks of each flow according to the detected length of the cast blanks and the detected weight of the cast blanks; by a length abnormity recognizing module, carrying out comprehensive comparison operation, and recognizing and deducing whether the actual length of the cast blanks is abnormal or not according to the weight-per-meter data of the cast blanks of each flow; after a length abnormity signal is received by a length abnormity correcting module, automatically calculating a cut length correcting quantity; receiving the length abnormity signal and displaying the received length correcting quantity by an alarm display module; and by the fixed-length cutting device, automatically correcting a real-time length detecting value sent by a length measuring sensor. The monitoring system and the monitoring method can automatically monitor whether the cut length of continuously cast blanks is abnormal or not on line.
Description
technical field [0001] The invention relates to a monitoring device and a monitoring method in the production process of steelmaking and continuous casting, in particular to a monitoring system and a monitoring method for on-line automatic monitoring of abnormal cutting length of continuous casting slabs. Background technique [0002] In steelmaking and continuous casting production, the hot solidified steel stream continuously drawn from the continuous casting machine needs to be cut into billets of a certain length according to the requirements of the subsequent steel rolling process, and transported to the The steel rolling process carries out rolling. The length of the slab produced by the continuous casting machine must meet the requirements of the rolling mill under the condition that the section specification remains unchanged, otherwise it will affect the yield of the rolled steel product and increase the waste of steel. Therefore, the cutting of the continuous casti...
