Embodiment 1

[0037] A specific embodiment of the present invention, such as figure 1 As shown, a slag layer thickness measuring device is disclosed, comprising a blowing rod 1, a cantilever 2, a rotating arm 3 probe 5, a controller 6 and a main control computer 7; one end of the cantilever 2 is connected with the upper end of the rotating arm 3, and the blowing The gas rod 1 is arranged at the other end of the cantilever 2, and the probe 5 and the controller 6 are respectively connected with the main control computer 7; the probe 5 is used to scan the liquid level image in the container to be measured; the controller 6 is used to control the cantilever 2 and the rotation The movement of the arm 3 enables the blowing rod 1 to move to the position to be tested, and the main control computer 7 is used for image processing and input of control commands.

[0038] Compared with the prior art, the slag layer thickness control device of this embodiment controls the position of the blowing rod 1 th...

Embodiment 2

[0069] Another specific embodiment of the present invention discloses a method for measuring the thickness of a slag layer. Using the device for measuring the thickness of a slag layer in Embodiment 1, the lower part of the container to be measured is molten steel, and the upper part is a slag layer. Air blowing can break the slag layer and form pits, and the air pressure can be blown to the liquid level of molten steel. In this method, the controller 6 controls the rotating arm 3 and the cantilever 2 to complete the action of the blowing rod 1 and perform blowing. gas, using the probe 5 to take the image of the liquid level formed by the blowing rod 1 in the container to be tested, and then process the image of the liquid level and obtain the thickness of the slag layer through the main control calculation 7. The steps include:

[0070]Step 1: Adjust the position of blowing rod 1.

[0071] The controller 6 controls the movement of the first motor, drives the rotating arm 3 to...

Abstract

The invention relates to a device and method for measuring the thickness of a slag layer, belonging to the technical field of metallurgy, and solves the problems of low measurement accuracy, poor safety and high labor intensity in the prior art of slag layer thickness measurement. The present invention comprises blowing bar, cantilever, rotating arm, probe, controller and main control computer; Connection; the probe is used to scan the image of the liquid level in the container to be tested; the controller is used to control the movement of the cantilever and the rotating arm, so that the blowing rod can move to the position to be tested; the main control computer is used for image processing and input of control commands . The invention adopts the controller to adjust the position of the blowing rod, and the liquid level height graph is taken by the probe, and the main control computer processes the image to obtain the thickness of the slag layer, which reduces human error, improves the measurement accuracy, and reduces the labor intensity of workers at the same time , improving work efficiency.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a device and method for measuring the thickness of a slag layer. Background technique [0002] In pyrometallurgy, when iron minerals are melted into molten iron at high temperature, some impurities in the ore form unmelted waste slag, which is called iron slag in steel production, and the iron slag floats above the molten iron. The molten iron contains a lot of slag, which is not conducive to converter smelting. During the converter smelting process, problems such as slag overflow and splashing are prone to occur, which is not conducive to index control and safe production. From the perspective of safe production and economic production, it is necessary to control the slag content of molten iron. Therefore, it is necessary to detect the slag content of molten iron. [0003] With the expansion of the scale of modern industrial production, the requirements for the variety and q...
