Linear laser measuring system used for high temperature continuous casting billet and method thereof

Abstract

The invention discloses a linear laser measuring system used for a high temperature continuous casting billet and a method thereof and relates to the laser measurement technology field. The linear laser measuring system used for the high temperature continuous casting billet is formed by a linear laser (1), an imaging lens (2), an area array CDD (3), a supporting communication module (4), and a computer (5) which are connected in a photoelectric signal mode. The method comprises the following steps of A, informing that the high temperature continuous casting billet arrives at a measurement area by a signal point; B, starting the linear laser (1) to project continuous laser lines on the surface of the high temperature continuous casting billet; C, carrying out high frequency scanning capture by the imaging lens (2); D, forming a two-dimensional image with high pixel accuracy through the area array CDD (3); and E, transmitting the two-dimensional image to a computer (5) system and the like in time through the supporting communication module (4). The system adopts non-contact object measurement and has advantages that a measurement speed is fast; measurement precision is high; data isstable; and the influences of a measurement object and a surrounding environment are small and so on.

Description

technical field [0001] The invention relates to the technical field of laser measurement, in particular to a linear laser measurement system and method for high-temperature continuous casting slabs. Background technique [0002] Under the high temperature condition of the slab just cut, the slab with irregular length is produced after the continuous casting slab is cut, and the physical data such as the specific length, width, and volume of the slab need to be accurately known, and the high temperature characteristics of the slab limit the conventional contact physical measurement means . Traditional measurement or manual measurement after waiting for the slab to cool, or using a measuring roller table for encoder counting; manual measurement needs to wait for the slab to cool, and the cast slab often needs to be hot-rolled, and after cooling, it must be reheated before being sent to the hot rolling , a waste of energy and low efficiency; the measuring roller table needs to...

Traditional measurement or manual measurement after waiting for the slab to cool, or using a measuring roller table for encoder counting; manual measurement needs to wait for the slab to cool, and the cast slab often needs to be hot-rolled, and after cooling, it must be reheated before being sent to the hot rolling , a waste of energy and low efficiency; the measuring roller table needs to be in direct physical contact with the billet, resulting in wear and tear after long-term use, and the measurement accuracy is reduced. Measuring rollers are more difficult to detect round billets
