AN AUTOMATED DEVICE FOR OPTIMISED MEASUREMENT OF MOVING HOT SLAB LENGTH IN A CASTER ROLL MILL .

摘要

This invention relates to an automated device for optimised measurement of moving hot slab length in a Caster roll mill to be cut in specified length accurately comprising of a pair of linear progressive area scan CCD Cameras (6) installed at a fixed distance from one another in the control pulpit of the caster line to view the hot slab (4), rolled on the caster table (3) and transmitting the images so formed of the slab to an image processing system integrated with the said cameras, the image processing system comprises of a high-end PC (7) with high resolution color grahics monitor (8), high speed frame grabber (2), DSP-based image processing cards and an image processing software (1), wherein the captured images by the cameras are sent to a frame grabber to be processed through an image processing card (10), operated and controlled by the image processing software(1) through the high end PC to save records and generate report (9) and display the accurate length of the hot slab to be cut by a gas flame.
