The heating furnace is the equipment that heats the material or workpiece to the forging temperature, which is widely used in many industries such as petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemical, pharmaceutical and so on. Energy problems are increasingly severe and enterprises are facing more and more fierce market competition, energy saving and efficiency is particularly important. This requires timely and accurate monitoring, analysis and optimization of the operating temperature of the heating furnace, the main energy consuming equipment in the steel and gold industry, in order to improve the operating efficiency of the heating furnace to achieve the purpose of energy saving and consumption reduction.

The traditional way to monitor the temperature of the heating furnace is thermocouple or point thermometer, which needs to manually record the temperature of the heating furnace, and needs direct contact with the furnace, which is easy to damage and relatively dangerous. At present, the more scientific way to monitor the temperature of the heating furnace is to use infrared thermal imaging instrument.

The advantages of infrared thermal imaging instrument to monitor the temperature of heating furnace:

1, non-contact temperature measurement: the infrared thermal imager adopts a non-contact temperature measurement method, which will not affect the normal operation of the heating furnace, and does not require manual measurement by the staff to avoid dangerous events;

2, high temperature measurement accuracy and wide range: infrared thermal imaging instrument temperature measurement accuracy is high, and can be carried out in a large span range temperature monitoring;

3. Real-time monitoring of data: the thermal camera can obtain the temperature change of the heating furnace in real time, and the thermal camera can measure the temperature of a large area at the same time, and the temperature data obtained is more real and complete;

4, automatic temperature data recording: infrared thermal camera in real-time acquisition of temperature data at the same time, can automatically record temperature information, the use of later viewing and analysis, better optimize the process;

5, abnormal warning: infrared thermal camera can set different alarm temperatures and alarm levels, once the abnormal temperature is detected immediately alarm to remind the staff to deal with;

6, easy to use: the infrared thermal camera has no vulnerable parts, one installation, can be used for many years, no special maintenance.

The application of infrared thermal imager to temperature monitoring of heating furnace can help to maximize energy utilization of heating furnace, improve technology level and reduce energy consumption.
