When the mixing furnace of the casting plant is heated for a long time, the bottom and side walls of the furnace are continuously eroded due to the flow of aluminum water. When the insulation brick and castable are damaged to a certain extent, the aluminum water contacts the bottom of the furnace or the side wall steel plate, and the temperature of the outer wall steel plate will rise, and the mixing furnace has the risk of aluminum leakage. At present, the temperature measurement operation of the mixing furnace is manually measured with infrared thermometer. The environment in the workplace is complex, the space is narrow, and there are dust, high temperature, and waste slag falling, which causes very big obstacles to the manual inspection, and there is a greater safety risk in the operation process of the measurement personnel. Due to the low efficiency of manual measurement, long interval, large deviation of temperature measurement position, different measurement habits and other factors, there are errors in the measurement data.
The on-line temperature detection system developed by Zhengzhou Jingwei Technology Industry Co.,LTD is a set of on-line temperature detection system of mixing furnace, which adopts temperature sensor technology, low-power microprocessor technology, low-power anti-interference wireless communication technology, three-dimensional modeling technology and computer software technology. The technology and equipment avoid the influence of human factors from the source; The real-time and accurate temperature monitoring and fault prediction in the running process of the mixing furnace are realized, so the above manual defects are technically solved.
