Embodiment Construction

[0011] Such as figure 1 As shown, the number of corrosion detection probes 2 of the induction furnace bottom blowing gas supply element corrosion detection device is 18, which are arranged around the induction furnace bottom blowing gas supply element 1, and are stepped along the direction of the gas supply element to the gas inlet. Arranged, the corrosion detection probe 2 is connected to the transmitter 4 through the connecting plug-in 3, the transmitter 4 is connected to the computer processing system 5, and the computer processing system has an A / D acquisition card. During the smelting process, the corrosion detection probe 2 transmits the measured temperature signal at the corresponding position around the bottom blowing gas supply element 1 to the transmitter 4, and the transmitter 4 converts the weak current signal measured by the corrosion detection probe 2 into The standard signal is transmitted to the computer processing system 5, and the computer processing system 5...

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment manufacturing, in particular to a corrosion detection device for an induction furnace bottom blowing gas supply element. Background technique [0002] In order to meet the needs of production and scientific research, it is necessary to install a bottom blowing gas supply element at the bottom of the induction furnace to supply gas to the molten steel in the furnace for bottom blowing and stirring, so as to meet the needs of stirring, refining and decarburization of molten steel. When installing bottom-blown gas supply components in induction furnaces to blow air into the furnace, especially when blowing oxygen into the furnace, due to high temperature, oxidation and severe scouring in the furnace, it is difficult to control the corrosion rate of the gas supply components, resulting in Components burn out and lead to steel breakout accidents. Due to the special structure of the ind...
