Device for detecting light intensity of flame

Abstract

The embodiment of the invention discloses a device for detecting light intensity of a flame, which comprises an optical telescope, an optical fiber connected with the optical telescope, a light filter lens and an optical spectrum processing module, wherein the optical telescope is used for acquiring optical spectrum information of the flame in a furnace mouth, the optical fiber is used for transmitting the optical spectrum information, the light filter lens is used for filtering the optical spectrum information and the optical spectrum processing module is used for processing the filtered optical spectrum information to obtain a light intensity value corresponding to the optical spectrum information, so that the device can detect the light intensity value of the flame in the furnace mouth without endurance of furnace-mouth high-temperature severe environment; therefore, the service life of the device is prolonged, the device can be assembled and maintained conveniently, and the detection of multi-way light intensity value is realized by operations of the multi-way optical fiber and the optical spectrum processing module.

Description

technical field [0001] The invention relates to the field of steelmaking detection, in particular to a flame light intensity detection device. Background technique [0002] The steel production of converter steelmaking accounts for more than 80% of the total steel production, and occupies a dominant position in the output of converter steel in large and medium-sized key iron and steel enterprises, and the control of the steelmaking end point in converter steelmaking is one of the key technologies of converter steelmaking. End point control of blowing in converter steelmaking is an important operation at the end of converter steelmaking, usually referring to removing phosphorus and sulfur to the range required by the end point as early as possible, so end point control mainly includes carbon content and temperature control . In the converter steelmaking process, the flame at the furnace mouth is an important basis for judging the carbon content of molten steel under the temp...

AI Technical Summary

Problems solved by technology

[0003] However, the current flame light intensity detection devices all need to detect the flame at close range, and the equipment should be installed at the furnace mouth, so they have to withstand the harsh environment of high temperature at the furnace mouth, resulting in the shortcomings of short service life and difficult installation and maintenance.
