Blast furnace tuyere equipment and periphery furnace body lining corrosion state patrol system and method thereof

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...

Problems solved by technology

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 cause water vapor explosion and cause a major production accident of molten iron outflow. Therefore, early detection of tuyere damage is an important prerequisite for ensuring safe production
