Abstract
The invention discloses a continuous casting billet sizing system. The continuous casting billet sizing system mainly includes a length measurement device which consists of a camera and a computer and is used for measuring the length of a continuous casting billet, a flame cutting device which is electrically connected to the computer and is used for cutting the continuous casting billet, and a laser distance measurement device which is used for measuring the distance from the laser distance measurement device to the flame cutting device; the camera is arranged on a position, wherein the distance from an original position of the flame cutting device to the position is equal to the length of the desired target continuous casting billet, and the camera is used for shooting billet head image information of the continuous casting billet; and the computer processes the billet head image information and calculates out the sizing length L according to a result measured by the laser distance measurement device, and sends the sizing length L to the flame cutting device to perform sizing cutting on the continuous casting billet. According to the invention, the length measurement device is compensated and corrected by a deviation value between a waiting position and the original position of the flame cutting device obtained by the laser distance measurement device, and in this way, the deviation of the length of the sized continuous casting billet is in a stable allowable range.
Description
Technical field
The present invention relates to steel-making continuous casting field, be specifically related to a kind of continuous casting fixed-length system.
Background technology
In steel-making continuous casting field, continuous casting fixed-length system is particularly important.The control accuracy of continuous casting fixed-length directly influences the lumber recovery of continuous casting billet, if the continuous casting billet cut out is oversize will result in very big waste, if too short bar or the tubing that just can not roll required finished product of the continuous casting billet cut out.Long technology surveyed by existing continuous casting billet mainly " mechanical type touches ball ", " encoder " and " video camera ", due to " video camera " technology have non-contact detecting, accuracy of detection height, the feature such as maintenance is little and replace contact measurement just gradually, accuracy of detection is poor, maintenance is big " mechanical type touches ball " and " encoder " technology.But, in actual applications, the continuous casting billet length deviation that adopt high " video camera " of accuracy of detection to survey sizing operation that long technology completes continuous casting billet to instruct flame-cutting plant still suffers from cutting out exceedes the scope of permission, thus can not meet modern production technological requirement.
Summary of the invention
It is an object of the invention to provide the higher continuous casting fixed-length system of a kind of precision to solve the problem that the existing continuous casting billet length deviation cut out is bigger.
For achieving the above object, the invention provides a kind of continuous casting fixed-length system, including the measuring motion for measuring continuous casting billet length being mainly made up of video camera and computer, the flame-cutting plant for cutting continuous casting blank electrically connected with computer, also include laser ranging system, for measuring its distance to flame-cutting plant, video camera is arranged on from the raw bits of flame-cutting plant to the position identical with the length of required target continuous casting billet, for absorbing the base head image information of continuous casting billet, this base head image information of computer disposal the result measured in conjunction with laser ranging system calculate cut lengths L, and send this cut lengths L to flame-cutting plant and be used for Length-fixing cutting continuous casting billet.
Further, the result that laser ranging system is measured includes:
Laser ranging system is to the distance L0 of flame-cutting plant raw bits；
Laser ranging system waits the distance Ln of position to flame-cutting plant, wherein, waits that position refers to that flame-cutting plant has cut backward raw bits every time and returned until stop and wait for the position cut next time.
Further, flame-cutting plant being installed with reflecting plate, the laser projections of laser ranging system is on this reflecting plate, for the distance of Laser Measurement range unit to reflecting plate.
Beneficial effects of the present invention: the distance returning to wait position after flame-cutting plant has cut every time by arranging laser ranging system to detect, thus obtaining the deviation value of this wait position and raw bits, again this deviation value it is used for compensating approach " video camera " measuring motion and provides cut lengths L, scale continuous casting billet length deviation out can be realized stably in allowed limits, meet modern production technological requirement.
Except purpose described above, feature and advantage, the present invention also has other purpose, feature and advantage.Below with reference to figure, the present invention is further detailed explanation.
Accompanying drawing explanation
Fig. 1 is continuous casting fixed-length system schematic.
Detailed description of the invention
As shown in Figure 1, continuous casting billet 2 moves on roller-way 1 from left to right with certain speed, flame-cutting plant 3 is arranged on the left end of continuous casting billet 2 for cutting off continuous casting billet, and when cutting continuous casting blank, it synchronizes to follow continuous casting billet and move right, and backs to left to again wait that position wait is cut next time after cut.This wait position refers to that flame-cutting plant has cut backward raw bits every time and returned until stop and wait for the position cut next time.Laser ranging system 4 is arranged near flame-cutting plant 3, measures it and sends computer to the distance of flame-cutting plant the result measured.Preferably, the result that laser ranging system is measured includes: laser ranging system is to the distance L0 of flame-cutting plant raw bits；Laser ranging system waits the distance Ln of position to flame-cutting plant.The distance returning to wait position after flame-cutting plant has cut every time by arranging laser ranging system to detect, thus obtaining the deviation value of this wait position and raw bits.Video camera 6 is arranged on from the raw bits of flame-cutting plant 3 to the position identical with the length of required target continuous casting billet, for absorbing the base head image information of continuous casting billet.Computer 5 is arranged on electric panel room and electrically connects with flame-cutting plant 3, laser ranging system 4 and video camera 6.The base head image information of computer disposal continuous casting billet and by laser ranging system measurement to wait the position deviation value with raw bits for compensating approach its cut lengths L calculated, and send this cut lengths L to flame-cutting plant and be used for Length-fixing cutting continuous casting billet.
Preferably, for obtaining good laser ranging effect, flame-cutting plant is installed with the reflecting plate 30 being exclusively used in laser-bounce.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
