Automatic temperature measuring device and method for LF (ladle furnace) of steel mill

Abstract

The invention discloses an automatic temperature measuring device and method for a steel mill LF refining furnace, and the method comprises the steps: enabling a camera device in a closed cooling space to be aligned with a steel ladle detection port, and carrying out the horizontal translation in a detection port region, so as to enable the camera device to carry out the sweeping detection of molten steel at the detection port; using an infrared camera in the camera device for obtaining temperature information of a steel ladle detection opening, and using a visible light camera of the camera device for observing dross on the liquid level of molten steel; controlling the horizontal position of the camera device through a computer control system, and obtaining temperature information and scum information at the same time; and performing cooling control on the closed cooling space through a computer system. The automatic temperature detection of the LF refining furnace can be automatically completed, the temperature measurement efficiency can be greatly improved, and the material consumption and the human labor input are reduced.

Description

technical field [0001] The invention belongs to the technical field of iron and steel smelting, and in particular relates to a temperature detection technology of an LF refining furnace in a steel plant. Background technique [0002] In steel mills, the temperature measurement of LF refining furnace is generally done manually, and the temperature measurement results directly affect the progress of the entire steelmaking process. [0003] The environmental characteristics of steel mills are high temperature, dust and noise. Moreover, the temperature of the LF refining furnace is as high as 1600 degrees Celsius during blowing. Under this circumstance, the staff need to use special temperature measuring tools to reach into the ladle for temperature detection, so as to obtain the temperature at that moment and at that location. The temperature measurement results at this time are related to the operation of the staff and will affect the efficiency of steelmaking operations. The...

Problems solved by technology

[0004] At present, the LF refining furnace of the steel plant adopts the traditional thermocouple contact temperature measurement. The thermocouple is a one-time consumable product, which is expensive and relatively high in cost; the temperature measurement process needs to be connected to a temperature controller, shielded wire, etc., and various equipment models Correspondence is required, and the process is cumbersome

And using this method to measure temperature requires subsequent data transmission, and there is a certain lag in information, which in turn affects the efficiency of steelmaking operations
