Description
Technical field:
The utility model belongs to the steel-making continuous casting production field, particularly a kind of weight-fixing cutting device of continuous casting blank.
Technical background
Along with the management development of steel rolling production process, the primary raw material that many enterprises produce steel rolling---continuous casting billet has proposed the requirement of delivery by weight.At present, in the continuous casting production technology of steel-making, most conticasters all adopt " scale " to shear control technology, promptly only the length of the continuous casting billet produced are made regulation, and only the length of continuous casting billet are detected; When the length of continuous casting billet reaches the length (scale) of regulation, utilize cutter or cutting machine that continuous casting billet is cut off, obtain having the continuous casting billet of specific length.Because in continuous casting production process, along with the wearing and tearing of crystallizer, the sectional dimension of continuous casting billet (width and thickness) becomes greatly gradually, therefore only shear the weight that control technology can not be controlled continuous casting billet by " scale ".There is the minority conticaster to adopt " fixed heavy " to shear control technology, weight to the continuous casting billet produced is controlled, but its control belongs to " weighing " combination " afterwards " cutting to length control mode, be that they are to send to weigh after continuous casting billet is cut off again, extrapolate the length variation of continuous casting billet then according to the continuous casting billet deviation of weight that weighs up, by revising the sheared length of next root continuous casting billet, go to control the weight of next root continuous casting billet.
Summary of the invention:
A kind of volumetric method weight-fixing cutting device of continuous casting blank of the purpose of this utility model, the continuous casting billet " scale " that solves in the continuous casting production process is sheared the problem that control technology can not be controlled continuous casting billet weight.
The technical solution of the utility model is: according to the continuous casting billet weight of technological requirement and the proportion of continuous casting billet, calculate the volume controlling value of continuous casting billet, it is characterized in that the composition of Weight-fixing cutting device is: video camera 1, the auxiliary measuring thickness device 2 of laser, continuous casting billet 3, straightening roller 4, non-contact displacement transducer 5, cutter or flame cutting machine 6, video camera 9.Video camera 1 is above 4 outlets of straightening roller, and the auxiliary measuring thickness device 2 of laser is at the oblique upper of straightening roller 4 outlets, and non-contact displacement transducer 5 is below straightening roller 4, and video camera 9 is above cutter or flame cutting machine 6 outlets.The auxiliary measuring thickness device 2 of video camera 1, laser, non-contact displacement transducer 5 and video camera 9 are input to Computer Image Processing and control system with the sectional dimension of the relevant continuous casting billet 3 that records and the information of length, Computer Image Processing and control system control cutter or flame cutting machine 6 actions are sheared or cutting continuous casting blank 3.
Before continuous casting billet is not cut off, adopt image processing techniques, accurately measure the area of section of continuous casting billet, calculate the length controlling value of continuous casting billet then according to the volume controlling value of continuous casting billet; Utilize image processing techniques, go to control the continuous casting billet sheared length of conticaster, just can obtain meeting the continuous casting billet that weight requires according to the length controlling value.
The area of section of continuous casting billet detects, and by the width situation of taking continuous casting billet from the top of continuous casting billet with 1 or multiple cameras 1, passes through Computer Image Processing, records the width (see figure 1) of continuous casting billet.
The auxiliary measuring thickness device 2 of laser cooperates with video camera 1, records the height of continuous casting billet end face, utilizes non-contact displacement transducer 5 to measure the diameter of conticaster straightening roller, measures the bottom surface height (see figure 1) of continuous casting billet indirectly.The end face of continuous casting billet and the difference in height of bottom surface are exactly the thickness of continuous casting billet.
The utility model can also cooperate with video camera 1 with the auxiliary measuring thickness device 2 of laser, records the height of continuous casting billet end face, directly records the bottom surface height (see figure 2) of continuous casting billet by video camera 7; The end face of continuous casting billet and the difference in height of bottom surface are exactly the thickness of continuous casting billet.Video camera 7 is installed in the side of straightening roller 4 outlets,
The thickness situation (see figure 3) that the utility model can also adopt one or more video camera 8 directly to take continuous casting billet through Computer Image Processing, records the thickness of continuous casting billet.Video camera 8 is installed in the side of straightening roller 4 outlets,
Just can determine the area of section of continuous casting billet by continuous casting billet width that records and thickness.
Continuous casting billet length detection and control.
According to the continuous casting billet weight of technological requirement and the proportion of continuous casting billet, can determine the volume controlling value of continuous casting billet.According to the volume controlling value of continuous casting billet,, can calculate the length controlling value of continuous casting billet with the continuous casting billet area of section that records.
Video camera 9 is used for measuring continuous casting billet length.Adopt 1 or multiple cameras 9, the situation (see figure 4) of taking the continuous casting billet head movement from the continuous casting billet top through Computer Image Processing, is determined the position of continuous casting billet head.When the continuous casting billet head arrives the position of continuous casting billet length controlling value correspondence, computer sends instruction, the cutter or the flame cutting machine of control conticaster cut off continuous casting billet, obtain the continuous casting billet that length is the length controlling value, to obtain volume and the corresponding continuous casting billet of technological requirement weight.
Compare with traditional continuous casting billet Weight-fixing cutting control technology, the utlity model has following advantage:
1. control in real time
The weight of every continuous casting billet all is to determine its sheared length according to area of section of himself and proportion, with its volume of accurate control.Control in time, accurately.
2. be convenient to implement
The mode that the utility model adopts image processing techniques and non-contact displacement measurement technology to combine is not done transformation and construction substantially to original equipment of conticaster and conveyor roller, need only utilize the repair time of conticaster that the checkout gear installation in position is got final product.
To continuous casting production without any influence
Because image is handled and non-contact displacement measurement all belongs to non-contact measurement, its debug and testing process to continuous casting production without any influence.
Provide continuous casting billet by weight, can improve the scale rate that steel rolling is produced, and then improve the Unit Weight value-added content of product, improve actual labor productivity by technological requirement; Can also reduce overstocking of non-scale product.
