Abstract
A constant-weight shearing device for continuous casting billets comprises a shearing device, a casting blank roller way, a casting blank flow and a control system, and is characterized in that a track beam perpendicular to a casting blank track is arranged above the casting blank flow of a continuous casting machine, a movable trolley is placed on the track beam, a weighing frame and a weighing sensor are mounted on the movable trolley, an electric push rod is arranged on the weighing frame and connected with a telescopic rod, the end part of the telescopic rod is fixedly connected with a carrying pole beam, and a lifter and a hand joint are mounted at two ends of the carrying pole beam. According to the invention, the weighing device is arranged on the weighing trolley, the weighing trolley covers N casting blank flows, namely the continuous casting blanks of the N casting blank flows are weighed by the same scale, so that the problem of multiple errors of multiple scales is avoided, and the control system corrects the sizing value according to the weighed weight of each flow of sizing blanks so as to achieve the purpose of maintaining each continuous casting blank within a certain weight range. The shearing device can realize the shearing of the fixed length and the fixed weight of the continuous casting billet, thereby improving the fixed length rate and the yield of the next steel rolling process of the continuous casting billet.
Description
Technical field
The present invention relates to a kind of weight-fixing cutting device of continuous casting blank in the metallurgy industry.
Background technology
Continuous casting billet friendship steel rolling process is as supplying one of base standard with " fixed length " always in the metallurgy industry, mostly adopt cutting to length, only require that the steel billet length that is sheared is in the margin of tolerance that should decide, and no matter whether its weight equal, because the influence that changed by cross dimensions, casting speed, throwing temperature, conical degree of crystallizer etc., same specification is cut its weight at different production order of classes or grades at school (as mornig shift, night shift) by equal length might be unequal.It is this that the unequal continuous casting billet of weight will cause very big trouble to the scale rate of next process steel rolling and the raising of lumber recovery by the equal length shearing.
Summary of the invention
Purpose of the present invention just provides a kind of weight-fixing cutting device of continuous casting blank that can carry out fixed length, Weight-fixing cutting to continuous casting billet.
Weight-fixing cutting device of continuous casting blank of the present invention comprises shear, strand roller-way, strand stream and control system, be characterized in above the strand stream of conticaster, being provided with the track girder vertical with the strand track, place travelling car on the track girder, weigh frame and LOAD CELLS are installed on the travelling car, the frame of weighing is provided with electric pushrod, electric pushrod links to each other with expansion link, and the end and the shoulder pole girder of expansion link are affixed, and elevator and swivel of hand are equipped with in the two ends of shoulder pole girder.
Weight-fixing cutting device of continuous casting blank of the present invention, because the continuous casting billet weighing device is installed on the dolly of weighing of a similar driving, the dolly of weighing can move on track girder and cover N strand stream, be that the continuous casting billet that the quilt of N strand stream is weighed is to use same table scale, avoided the problem of the numerical value deviation of weighing of a plurality of errors of many platform balances.The condition of production according to conticaster, can arrange the continuous casting billet of cutting to length to be weighed once in every x hour, weighing-up wave directly passes to the control room of continuous casting control scale, the weight correction scale numerical value that control system weighs up according to every stream scale base, keep the purpose of every continuous casting billet in the constant weight scope, i.e. " Weight-fixing cutting " to reach.It can be realized continuous casting billet fixed length, fixed heavy shearing, thus the scale rate and the lumber recovery of following one steel rolling process of raising continuous casting billet.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is Fig. 1 side direction structural representation.
The specific embodiment
A kind of weight-fixing cutting device of continuous casting blank comprises shear, strand roller-way 1, strand stream and control system, be characterized in above the strand of conticaster stream, being provided with the track girder 12 vertical with strand roller-way 1, place travelling car 8 on the track girder 12, weigh frame 10 and LOAD CELLS 9 are installed on the travelling car 8, the frame 10 of weighing is provided with electric pushrod 11, electric pushrod 11 links to each other with expansion link 7, the end of expansion link 7 and shoulder pole girder 5 are affixed, elevator 3 and swivel of hand 6 are equipped with in the two ends of shoulder pole girder 5, and swivel of hand 6 can be picked up the steel billet on the strand roller-way 12.
Control system is controlled the strand stream top that travelling car 8 is positioned to weigh as requested automatically, control swivel of hand 6 is picked up steel billet 2 implementations and is weighed, according to weighing the data of gained weight and the difference of target weight, control system is revised automatically and is cut base length, thereby reaches the purpose of weight in certain error range of the steel billet of cutting 2.
