Infrared thermometers used in ironmaking
Measurement of hot stove vault temperature
The hot stove vault is a special occasion, the vault temperature measurement not only to solve the high temperature and high pressure problem of the target, but also to adapt to the requirements of the open-air environment changes throughout the year. After repeated practice and improvement, we have designed a set of special protection device with sealing window. The method of use is to be equipped with a protective device infrared probe, fixed installation in the vault on the original insertion of thermocouples on the position, so that the probe can be sealed through the window and the thermocouple jacks, aiming at the interior of the hot stove, measured the temperature of the hot stove vault, the probe signal through the cable to the instrumentation installed in the control cabinet box processed to display the temperature value, and the output of the 4-20mA standard current signal, sent to the logger or the computer to carry on the processing. Processing. Because the infrared probe of this system does not contact the high temperature target, so it has the characteristics of stable and reliable, long service life, usually can run continuously for more than five years, can reduce the consumption of thermocouples, greatly reducing equipment operating costs and maintenance workload.
Measurement of the internal temperature of the hot air duct
The system's temperature measurement device and the vault temperature measurement system is basically similar, will be equipped with a protective device with infrared probe installed in the hot air pipe the original thermocouple jack, the infrared probe through the protective device sealing window, and then through the original thermocouple jack, aiming at the interior of the hot air pipeline, so as to measure the temperature of the interior of the hot air pipeline. As the system's temperature probe is installed in the sealing window outside, the entire temperature measurement system and the pipe is completely isolated from the hot air, so the system in the replacement of the probe or other maintenance work can be carried out without affecting the working condition of the pipe hot air. The original commonly used thermocouples must be replaced in the rest of the wind state, coupled with the thermocouple is a consumable product, damage is more frequent. This temperature measurement system can reduce the consumption of thermocouples, reduce the operating costs of the equipment, the system has been Bensteel, Chengshan Steel, Lai Steel and other units to use, and has achieved good economic results.
Measurement of molten iron temperature before furnace
HDIR series of infrared thermometer measurement of molten iron before the furnace is: the infrared temperature probe equipped with a blowing set of fixed installation in the iron from the 5-15 metres of the bracket, and aiming at the iron ditch, each furnace molten iron for continuous scanning measurements, and the probe measured temperature signals connected to the recorder to print the temperature curve or sent to the computer for data processing. The biggest advantage of this system is that it can automatically and continuously measure the temperature of molten iron in each furnace, which can effectively avoid the influence of human factors brought about by manual insertion temperature measurement method. By analysing the recorded temperature curve or other computer processing information, it can truly reflect the trend of molten iron temperature in each furnace, and intuitively read out the *high temperature of each furnace, which provides a strong basis for production management and process improvement. At present, this system has been used by EGang, Shougang and other units, and has gained good comments from users.
