Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting billet production equipment, in particular to an on-line weighing device for continuous casting billets. Background Art

[0002] For a long time, restricted by existing equipment and technological conditions, many steel enterprises have taken fixed-length cutting as a production control element for continuous casting billets. However, during the continuous casting process, due to reasons such as the wear of the mold, changes in the molten steel alloy composition, pouring temperature, and drawing speed, there will be a large difference in the weights of continuous casting billets of the same length poured in different time periods in the same strand, thus affecting the yield index of the subsequent rolled bars.

[0003] After the existing continuous casting billets are produced, a weighing device is used to measure the weights of the continuous casting billets in different time periods, so as to make timely adjustments to the produced continuous casting billets. However, the above method requires lifting the continuous casting billets to the weighing device by a traveling crane for weighing. However, the utilization rate of the traveling crane in other aspects is also relatively high, so it is impossible to lift the continuous casting billets in a timely manner. As a result, some enterprises choose to use an on-line weighing device for continuous casting billets to avoid the intervention of the traveling crane. However, if there is a weighing deviation in the on-line weighing device, it will lead to inaccurate measurement of the weight of the continuous casting billets. Moreover, the existing on-line weighing devices basically belong to one link in the entire production line. Even if there is a weighing deviation in the on-line weighing device, it is impossible to detect it in time and calibrate the on-line weighing device.

[0023] Refer to Figure 1, an online weighing device for continuous casting billets, comprising: a fixing part 100, a weighing part 200 and a weighing part 300. The fixing part 100 is arranged on one side of a steel hooking machine, and a placing platform capable of carrying a continuous casting billet 500 is provided on the top of the fixing part 100, so that the continuous casting billet 500 can be hooked onto the placing platform by the steel hooking machine. There are two weighing parts 200, which are symmetrically arranged on both sides of the bottom of the fixing part 100, so that the continuous casting billet 500 hooked onto the placing platform can be weighed by the weighing part 200. The calibration part 300 is arranged at the middle of the bottom of the fixed part 100, and a plurality of standard weights 400 are arranged on the calibration part 300. A plurality of guarantee weights are placed on the ground and connected to the calibration part 300. The calibration part 300 can respectively lift the plurality of guarantee weights from the ground, so that the plurality of standard weights 400 are all suspended, so that the weighing part 200 can measure the weight of the plurality of standard weights 400. When the continuous casting billet 500 is not placed on the placement platform of the fixed part 100, the calibration part 300 lifts the plurality of standard weights 400, so that the weight of the plurality of standard weights 400 can be measured by the weighing part 200, so that the weighing deviation value of the weighing part 200 can be obtained by comparing the actual weight of the plurality of standard weights 400 with the displayed weight of the plurality of standard weights 400 measured by the weighing part 200, and the weighing of the weighing part 200 can be calibrated. In this way, after the calibration part 300 places the multiple standard weights 400 back on the ground, and then hooks the continuous casting billet 500 onto the placement platform of the fixing part 100, the accuracy of the actual weight measurement of the continuous casting billet 500 by the weighing part 200 can be guaranteed, thereby improving the subsequent yield index of the rolled bars.

[0024] In some specific embodiments of the present invention, the online weighing device for continuous casting billet 500 further includes: a controller. The signal output end of the calibration unit 300 and the signal output end of the weighing unit 200 are respectively connected to the signal input end of the controller, the calibration unit 300 can send the actual weight of the lifted multiple standard weights 400 to the controller, and the weighing unit 200 can send the measured displayed weight of the multiple standard weights 400 to the controller, so that the controller can compare the actual weight of the multiple standard weights 400 with the displayed weight measured by the weighing unit 200, and then obtain the weighing deviation value of the weighing unit 200. At the same time, the signal output end of the controller is also connected to the signal input end of the weighing unit 200, and the controller can send the weighing deviation value of the weighing unit 200 to the weighing unit 200, so that the weighing unit 200 can calibrate the weight by itself.

[0025] In some specific embodiments of the present utility model, the fixing part 100 includes: a cross beam 110 and a bracket 120. The cross beam 110 is horizontally placed, and both ends of the cross beam 110 are mounted on two weighing parts 200, and the cross beam 110 is supported by the two weighing parts 200. There are multiple brackets 120, and the multiple brackets 120 are vertically arranged on the top of the cross beam 110, and the multiple brackets 120 are evenly arranged along the length direction of the cross beam 110, so that the tops of the multiple brackets 120 jointly form a placement platform. Among them, rotating rollers are also arranged on the tops of the multiple brackets 120, so as to facilitate the billet hooking machine to hook the continuous casting billet 500 onto the multiple brackets 120.

[0026] In some specific embodiments of the present utility model, the weighing part 200 includes: a bottom plate 210, a weighing assembly 220 and a weighing platform frame 230. The weighing assembly 220 is arranged above the top surface of the bottom plate 210. The weighing platform frame 230 is arranged on the top of the weighing assembly 220, and one end of the cross beam 110 can be mounted on the top of the weighing platform frame 230. As the cross beam 110 applies pressure to the weighing platform frame 230, the weighing assembly 220 can measure the weights of various items placed on the weighing platform frame 230. The weighing platform frames 230 of the two weighing parts 200 can respectively support the two ends in the length direction of the cross beam 110. As the billet hooking machine hooks the continuous casting billet 500 onto the multiple brackets 120, under the weight of the continuous casting billet 500, the cross beam 110 will apply pressure to the weighing platform frames 230 of the two weighing parts 200, so that the displayed weight of the continuous casting billet 500 can be measured by the weighing assembly 220. Among them, the weighing part 200 further includes: a sensor base. The sensor base is arranged between the bottom plate 210 and the weighing assembly 220 and is connected to the weighing assembly 220. The weighing assembly 220 can be connected to the controller through the sensor base, so that the displayed weight measured by the weighing assembly 220 can be sent to the controller.

[0027] In some specific embodiments of the present utility model, the weighing calibration unit 300 includes: a pneumatic device 310 and a chain 320. The pneumatic device 310 can be an air pump.

The other end of the chain 320 is fixedly connected to the standard weight 400, so that the standard weight 400 can be driven to move up and down together by the ascending and descending chain 320. When the pneumatic device 310 drives the chain 320 to drive the standard weight 400 to rise, the cross beam 110 will apply pressure to the weighing table frame 230 of the weighing unit 200, so that the weight of the multiple standard weights 400 can be measured through the weighing assembly 220. Among them, the signal output ends of the multiple pneumatic devices 310 are all connected to the signal input end of the controller. When the pneumatic device 310 is started and drives the chain 320 to drive the standard weight 400 to rise, the pneumatic device 310 can send a signal to the controller. The controller can obtain the number of the rising standard weights 400 through the number of the pneumatic devices 310 that send signals, and then the actual weight of the multiple rising standard weights 400 can be obtained. Among them, the weight of the standard weight 400 is 1 ton.
