Embodiment 1

[0033] like figure 1 Shown is a blast furnace body with 16 tuyere devices 4 installed on the tuyere device and its surrounding furnace lining erosion status inspection system, including an image acquisition system and an image processing system.

[0034] The image acquisition system is set on the blast furnace operation site, which includes image acquisition equipment, inspection trolley 7, circular track 6 and on-site relay box 10 arranged on the circular track 6; wherein,

[0035]The circular track 6 is arranged on the outer periphery of the blast furnace body 1 along the circumferential direction of the blast furnace body 1; the inspection trolley 7 is arranged on the circular track 6 and runs clockwise or counterclockwise along the circular track 6; On the ceiling 2 of the tuyere platform above the tuyere device 4, a plurality of ring track supports 3 are arranged at intervals along the circumferential direction, so that the ring track 6 is fixed on the bottom of the plura...

Embodiment 2

[0046] A method for detecting the erosion state of the blast furnace lining realized by using the blast furnace tuyere equipment 4 and its surrounding furnace lining erosion state inspection system in the above embodiment 1, the steps are as follows:

[0047] S1. The inspection trolley 7 travels at a constant speed along the circular track 6, and adopts the same interval time to obtain the infrared thermal images collected by the thermal imager in real time; wherein, the interval time for obtaining the infrared thermal images satisfies the requirements of two consecutive images collected by the same thermal imager. There is a slight overlap between the images of the infrared thermography of the furnace body;

[0048] At the same time, during the operation of the inspection trolley 7 along the circular track 6, the RFID reader on it sequentially reads the RFID electronic tags set on each blast furnace tuyere device, and records the corresponding RFID tags. The reading time of t...

Abstract

The invention discloses blast furnace tuyere equipment and a periphery furnace body lining corrosion state patrol system and method thereof. The system comprises a thermal imager, a patrol trolley, aring-shaped track and an image processing system. The ring-shaped track is arranged on the periphery of the blast furnace body in the circumferential direction of the blast furnace body. The patrol trolley is arranged on the ring-shaped track. The thermal imager is installed on the patrol trolley to collect thermal images of the blast furnace tuyere equipment and the periphery furnace body thereofin real time. The image processing system is connected with the thermal imager. The obtained infrared thermal images are processed to obtain the highest temperature value of different detection areasof the furnace body within the infrared thermal image collecting range, so that whether abnormal temperature occurs or not is judged and the corrosion state of a furnace body lining is detected. According to the patrol system and method, by means of monitoring over abnormity of the surface temperature of the blast furnace body, the purpose of detecting the damage situation of the blast furnace tuyere equipment and a periphery furnace body lining material thereof is achieved, and the equipment can be pre-detected and pre-repaired reasonably and beneficially in advance.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a blast furnace tuyere equipment and a system and method for inspecting the erosion state of the furnace lining around it. Background technique [0002] In the iron-making blast furnace system, the blast furnace tuyere is a very important equipment, which undertakes the important task of injecting hot air into the blast furnace, and is an important guarantee for the safe production of the blast furnace. Due to its long-term exposure to high temperature, corrosion, thermal fatigue and abrasive erosion, the tuyere platform equipment and blast furnace lining, especially the blast furnace lining between the tuyere equipment and in the annular zone where all the tuyere equipment is located, is easy to burn. Let the cooling water flow into the blast furnace, causing the furnace temperature to drop. In severe cases, it may also lead to steam explosion, resulting in a major productio...
