Background technology
In hot rolling is produced, cause damage for fear of steel billet nose and button tail to the BJL electromagnetic oven, need vertically go into the side surface shape that steel billet is detected in the stokehold at steel billet, when the steel billet nose surpasses setting range with the button tail, provide alerting signal, thereby avoid of the damage of bad slab electromagnetic oven.This surveying instrument utilizes computer image processing technology to detect the steel billet side view based on the visual imaging principle, thereby avoids nose and the excessive slab of button tail to enter the BJL electromagnetic oven, thereby effectively protects the BJL electromagnetic oven.
Steel billet shape measure and billet surface shape measure are retrieved, do not found similar techniques.
Summary of the invention
The purpose of this utility model is to detect problem in real time in order to solve BJL inlet steel billet shape, be mainly a kind of steel billet side view measuring instrument of avoiding steel billet nose button tail to cause the damage problem of BJL electromagnetic oven and designing, CCD (chargecoupled device charge-coupled image sensor) be applied to the measurement of hot rolling steel billet based on digital CCD above warning value.
The technical solution of the utility model: the steel billet side view measuring instrument based on digital CCD of the present utility model comprises signals collecting part and signal processing, its signals collecting partly adopts the camera that is made of ccd sensor, and signal processing adopts industrial computer; Camera comprises the camera casing, and ccd sensor places the optical lens back in the camera casing, and ccd sensor is connected with special-purpose visual disposable plates, and special-purpose visual disposable plates is powered by power supply; Special-purpose visual disposable plates is connected with outside industrial computer by communication card.
Described steel billet side view measuring instrument based on digital CCD is established the optics dustproof glass before the optical lens; In the camera casing outside cooling jacket is installed.
Described steel billet side view measuring instrument based on digital CCD is established optical filtering in the optical lens front; On the camera casing, air intake opening is arranged, be used to be pressed into gas, make and form malleation in the cavity.
The beneficial effects of the utility model: this measurement scheme can well solve the real-time measurement for BJL inlet steel billet shape, can provide warning timely for steel billet nose that exceeds setting range and button tail phenomenon, has good result of use.
Based on the visual imaging principle, can effectively extract the shape of the required Measuring Object of measured zone based on the steel billet side view measuring instrument of digital CCD, because of adopting digital measurement transmission technology, on the transmission of signal and reliability, improve a lot.
Can form malleation in the camera cavity, make the small malleation of the preceding maintenance of camera lens, further reduce the surface contamination of glass.Adopted special-purpose optical filtering technique, overcome under the high temperature red steel and pulled the measuring error that the edge diffusion causes, made the extraction of steel billet margin signal more accurate.
