Center Rise - Model ZBF-T000 -High-Precision Water Temperature Difference Monitoring System for Blast Furnace

The product developed for measuring the cooling water temperature difference for a blast furnace wall

The high-temperature and high-pressure equipment such as metallurgical iron-making blast furnaces often require water to cool the high-temperature furnace body and high-temperature pipelines. In these places, it is very important to monitor the temperature and temperature difference between the inlet and outlet of the cooling water. However, the monitoring of cooling water heat load and water temperature difference of blast furnace cooling stave has always been a difficult problem that cannot be ignored in blast furnace production but has not been solved by effective means.

The high-precision water temperature difference monitoring system developed by our company for the blast furnace operation site can accurately, real-time and effectively monitor the cooling water temperature of blast furnace and water temperature difference. It is a real-time monitoring system integrates on-site data collection, real-time picture update, data analysis and processing, and automatic report generation. At the same time, it can store data and provide sound and light alarm, which is convenient for management and production personnel to analyze and operate. The system database allows other system calls to facilitate coordination with other systems.

The application of the system can effectively strengthen the real-time detection of the temperature difference between the inlet and outlet water of the blast furnace cooling system. It is also an important measure to prolong the life of the blast furnace and ensure safe production.

The system collects the temperature value in real time through the professional temperature data acquisition unit installed on the furnace wall, and can amplify and convert the signal through the signal processing part, and uploads it to the analysis system in the monitoring computer in the central control room through the communication cable. The special communication interface and special software processes the data to realize a series of data display and processing work, analyze the real-time changes of each cooling stave of the blast furnace, and then conduct induction, comparison and calculation to obtain the technical signals and technical parameters required on site.

By setting the upper and lower limit values for important monitoring data, the real-time alarm system can reflect whether there is any abnormality in the blast furnace in the first time; by viewing and analyzing historical data, we can know the service condition of furnace body in each period, which provide a strong scientific basis for the next stage of decision-making.

The system can monitor the instantaneous flow of each cooling stave and cooling water pipeline and the water temperature difference between the inlet and outlet pipelines in real time and continuously, and calculate the thermal load value accordingly, so as to control the temperature changes inside and outside the blast furnace, and ensure the normal production and operation of the blast furnace and increase the service life of the blast furnace.
