Abstract

A continuous casting square billet corner defect automatic pre-warning system comprises an image acquisition unit, a casting flow tracking unit, an analyzing and processing unit, an alarming display unit and a storage recording unit. The continuous casting square billet corner defect automatic warning system is characterized in that an image acquisition card is used for performing high-speed sampling on video signals and completing digitalized conversion, and digitalized image information capable of being processed by the analyzing and processing unit is formed. By means of the technical scheme, the timeliness and the effectiveness of pre-warning are high, running is reliable, cost is low, interference caused by scale and other spurious signals is avoided, automatic pre-warning can be achieved at the early stage when the continuous casting square billet corner defect is formed, and an effective mean is provided for abnormality monitoring and fast processing of the state of a casting machine; and the occurrence risk of the batch angle quality of continuous casting billets can be effectively reduced, the finished product rate can be increased easily, and product quality loss is reduced.

Description

technical field [0001] The invention relates to the technical field of continuous casting process monitoring and control in the iron and steel industry. Specifically, the invention relates to an automatic early warning system and method for corner defects of continuous casting billets. Background technique [0002] The cooling and solidification process of the steel stream in the continuous casting machine is the key to forming high-quality continuous casting slabs. In the steelmaking and continuous casting process, liquid steel is condensed into a billet with a certain shell thickness and shape through the primary cooling of the crystallizer and the secondary cooling of the spray rack in the second cooling chamber. In the actual production process of continuous casting, due to the influence of the working conditions of the casting machine, such as the wear of the mold, the leakage of the spray frame, the blockage of the nozzle and other factors, when the high-temperature st...
