Wide range of pyrometers used in various industrial fields
The application possibilities of different pyrometers are extremely wide. The sharp price drop in recent years has opened up more and more application fields, especially in low temperature areas or used to replace ordinary traditional thermometers. The following is the application of pyrometers in various industries Introduction to the field.
Metallurgical Industry
In the metallurgical industry, infrared temperature measurement is used in various fields. For example, the diagnosis of inner wall defects of various furnace bodies, the diagnosis of stave damage, the control of process parameters, etc. Infrared temperature measurement can accurately monitor the condition of the equipment, improve the service life of the equipment, save energy, reduce costs, and improve product quality. It can be seen that the traditional thermometer will be a product of the era of elimination, and it will disappear or be damaged over time, so that Constant replacement is required, and the pyrometer has no wearing parts, so its service life is theoretically unlimited, so its more expensive investment cost is paid back in the short term. The pyrometer can be installed on the side or on the top, avoid oblique alignment, so that the pyrometer is only caught on the edge, and the axial gap nozzle should not be placed on the lens of the pyrometer. When the ambient temperature is high, An additional cooling unit is required.
concrete processing industry
In concrete processing, temperature plays a key role in the setting time and thus the firmness. Especially for safety concrete, a certain processing temperature must be reached, and the contact probe will be damaged mechanically due to the corrosive action of cement. The pyrometer can directly accept the temperature of the mixing drum, and it can also be the temperature at the concrete outlet. Because of the requirements of ISO9000 quality inspection, the temperature must be recorded in the form of a file together with other production parameters, which is suitable for dirty industrial environments. , requires a very strong, such as dust-proof, waterproof measuring lens, in order to protect the pyrometer, use suitable accessories such as axial gap nozzle, optical mirror protection cover and insulating tube.
ceramic industry
For the production of ceramic materials, it is necessary to know the temperature change process during the combustion process in order to achieve the same quality products and avoid waste products. At the same time, in order to save energy, the temperature must be controlled within the minimum value. So far, thermometers have been used to measure the temperature. , what it gets is the room temperature, for which the pyrometer has an advantage, it can directly measure the temperature of the surface of the object, and it is in a very short time, so that it can accurately measure and maintain the combustion temperature.
paper industry
In paper refining, the paper track will run between a heated metal roll and a plastic-coated finish roll, and if the paper width is smaller than the roll width, the temperature at the edge of the finish roll will be much higher than that in the middle , the temperature difference between the middle and the edge cannot exceed the established absolute temperature, otherwise the plastic coating will be damaged. In order to measure the temperature, each frame can be equipped with three fixed pyrometers, or a pyrometer can be used to move along the length of the roll on the aimer device. Due to the local strong steam, a waterproof pyrometer and a nozzle with axial gap are required. , for free blowing of the window, because the temperature processing requires an SPS machine, so the general instrument can be corrected with emissivity.
