Online calibration device for bale weighing sensor of a continuous casting machine in a steel plant and use method

Abstract

The invention relates to an online calibration device for a bale weighing sensor of a continuous casting machine in a steel plant. The online calibration device comprises a driving module arranged on one side of a bale arm and a calibration module arranged on the driving module, the driving module comprises a mechanical arm and a calibration part, the calibration part is arranged at the top end of the mechanical arm, and a calibration cavity convenient for placing the bale arm is formed in the calibration part; the calibration module comprises a hydraulic station and a hydraulic jack, an ejector rod of the hydraulic jack faces downwards, the bottom of the hydraulic jack is fixedly connected with the inner top of the calibration cavity, the hydraulic station is arranged on the outer side of the calibration part and located on the mechanical arm, and the hydraulic station communicates with the hydraulic jack through an oil pipe. The invention also discloses a use method of the online calibration device for the bale weighing sensor of the continuous casting machine in the steel plant, which is used for carrying out online calibration on an unloaded bale arm during normal production of the continuous casting machine. The weighing accuracy is improved on the premise that production is not affected, and normal production is facilitated.

Description

technical field [0001] The invention relates to the technical field of calibrating devices, more specifically, it relates to calibrating devices and usage methods for ladle weighing sensors of continuous casting machines in online steelmaking plants. Background technique [0002] The continuous casting machine ladle in the steelmaking plant needs to be recalibrated after a period of use. The general calibration method is to hoist the weight bag to the continuous casting machine ladle through the crane during maintenance. According to the continuous casting machine ladle test The weight of the obtained weight bag is compared with the standard weight of the weight to adjust the large bag scale of the continuous casting machine. However, in the actual calibration, due to the frequent use of the crane and the need to apply before using the crane, the weight bag is hoisted to the large bag arm for comparison and calibration, and it is often necessary to wait for the crane to be f...

Problems solved by technology

However, in the actual calibration, due to the frequent use of the crane and the need to apply before using the crane, the weight bag is hoisted to the large bag arm for comparison and calibration, and it is often necessary to wait for the crane to be free.

Moreover, the longer the storage time of the weight bag, it is easy to be corroded, and the actual weight of the weight bag is different from the calibrated weight. Using this kind of weight bag cannot effectively calibrate the large bag weighing sensor of the continuous casting machine. In addition, the weight bag The weight is generally more than 100 tons, and there are safety risks in hoisting with cranes
