Problems solved by technology

When using this device and method for calibration, when the nut is rotated to adjust the height of the billet, the labor intensity of the operator is high and the speed is slow. Fixed, the measurement error is large, and the work efficiency is low
Moreover, during the calibration process, the operator's body parts will be exposed to gamma rays, which will cause great harm to the human body

Abstract

The invention discloses a billet continuous casting machine crystallizer liquid level cesium source calibration device and a method, belongs to the technical field of billet continuous casting machinecrystallizer liquid level control, and is used for calibrating a billet continuous casting machine crystallizer liquid level cesium source. A technical scheme of the invention is as follows: a chainblock is mounted on a calibration bracket, a lower end of the chain block is connected with an upper end of a pointer base through an upper chain, a lower end of the pointer base is connected with theupper end of a calibration test block through a lower chain, scale plate box is a rectangular box body of which upper and lower ends are opening, the scale plate box is fixed on a middle cross beam of the calibration bracket, the pointer base is located in the scale plate box, the pointer base and the scale box are in up-down siding fit, a front board of the scale plate box is provided with a scale plate visual window, the pointer base is provided with a pointer in a horizontal direction corresponding to the scale plate visual window, and a surface of the scale plate box at outside of the scale plate visual window is provided with a scale opposite to the pointer. The calibration device provided by the invention is rational in structure and easy to operate, a calibration method is simple and convenient, so the device and the method can improve calibration precision, reduce work intensity and improve efficiency of calibration works.

Description

technical field [0001] The invention relates to a cesium source calibration device and method for automatic control of the crystallizer liquid level of a billet continuous casting machine, and belongs to the technical field of control equipment and methods for the crystallizer liquid level of a billet continuous casting machine. Background technique [0002] In the iron and steel metallurgy industry, the billet continuous casting machine has been widely used. During the production process of the billet continuous casting machine, the molten steel is cooled and condensed in the crystallizer and converted into billets. At present, the cesium source liquid level control system is used to automatically control the molten steel level in the mold. During the casting process of the billet continuous casting machine, the cesium source installed on one side of the mold emits gamma rays, and the cesium source on the other side of the mold emits gamma rays. The gamma ray sensor is ins...
