System introduction
HJK-FK series endoscope ultra-high temperature infrared thermal imaging temperature detection and analysis system is specially used in high temperature environment to realize continuous real-time monitoring of the operating status in the furnace. The system is composed of infrared thermal imaging module, high temperature resistant infrared thermal imaging lens, automatic recoil protection device, furnace wall mounting kit, air filtration system and control box, and intelligent temperature measurement software. It solves the following pain points: flame and dust interference makes it difficult to obtain true furnace temperature, high temperature environment accelerates equipment aging and shortens service life, and traditional inspection fails to detect furnace anomalies in time.
Product features
1. All-weather passive infrared temperature measurement function
2. Intelligent temperature measurement algorithm for accurate temperature measurement
3. Supports ONVIF protocol
4. Does not depend on system platform; can directly log in to the web IP address to access the image and configure settings; can directly output alarm signals to PLC or an alarm device
5. Expansion length can be customized to suit a variety of kiln wall thickness
6. Spiral air curtain design keeps the lens free of dust accumulation
7. Integral stainless steel material provides corrosion and temperature resistance
8. Direct viewing endoscope head
9. Automatic exit and fault indication
10. Electric or pneumatic transmission mechanism
11. High temperature resistant optical pinhole lens with dust resistance
12. Over-temperature, under-voltage, or power failure causes automatic exit from the furnace
Application
The equipment is designed to withstand extreme temperature up to 1600°C.
It can be used for grate cooling machine blanking, steel plant heating furnace, annealing furnace, heat treatment furnace, waste treatment plant incinerator and other industrial high temperature furnaces.
Equipment value
1. With the thermal imaging system, operators can clearly see the temperature distribution, gas flow direction, and burden distribution inside the furnace. Based on these data, they can precisely adjust the charging ratio of coke and ore, and change the diameter, length, or number of tuyeres to ensure optimal gas flow distribution. This effectively reduces the coke ratio (i.e., the amount of coke consumed per ton of pig iron). In the current environment of high raw material prices, this represents the most core source of cost savings. Furthermore, the thermal imaging system can help quickly establish reasonable gas flow during the furnace startup phase, shortening the time needed to reach full production.
2. The charging chute at the top of a blast furnace is highly susceptible to wear in high-dust and high-temperature environments. Once it wears through, the consequences can range from a furnace stoppage lasting several days to, in severe cases, damage to internal furnace equipment. The infrared system clearly monitors the condition of the chute and issues an immediate warning upon detecting any abnormality, potentially avoiding economic losses amounting to millions of money.
3. Disturbed gas flow distribution is a primary cause of major furnace malfunctions such as "hanging" and "slipping," which are extremely costly to address each time they occur. The infrared system captures gas flow distribution anomalies in real time, guiding operators to intervene early. The economic benefit of avoiding just one such incident can also reach millions of money.
Case
Related Applications
Built on its core infrared thermal imaging technology, HJK-FK is a series of intelligent monitoring systems designed for harsh working conditions such as high temperature and heavy dust. It extends the high-temperature resistant lens into the furnace through a telescopic device, while the core module is placed outside the furnace for real-time monitoring.
