How Casting Infrared Thermometers Improve Measurement Accuracy

Xi'an Deli Automation Instrument **** is engaged in the research and development and manufacturing application of various temperature measuring instruments professional company, long-term engaged in non-contact temperature measurement, contact temperature measurement and automatic control work, with optical, mechanical, electronic and other technical design capabilities. At the same time, we have rich experience in industrial field application, and can provide special product design and a variety of accessories according to user needs, so as to provide customers with high-quality and comprehensive temperature measurement and control solutions.

The most commonly used methods for measuring the temperature of molten iron and molten steel in the foundry industry are optical pyrometers and fast thermocouple insertion methods. Among them, the temperature measurement accuracy of optical pyrometer is low, and it cannot be connected to recording equipment such as recorder or printer because it has no corresponding electrical signal output, and the measured temperature can only be recorded manually, and the authenticity of the recorded data cannot be guaranteed. In the fast thermocouple insertion method, although the temperature value can be recorded by the recorder, because the fast thermocouple can only measure the temperature at the moment of insertion, and can not measure the temperature continuously for a long time, it can only measure a few points in the smelting process, and the temperature change of the whole process cannot be mastered, and each time the temperature measurement must be manually inserted and operated, a galvanic couple can only be used 1-2 times, the galvanic consumption is larger, the cost is high and the use is more troublesome.

After the application of the continuous casting molten steel thermometer, as long as it is fixed and installed at an appropriate position within 5 meters from the furnace mouth, and aligned with the furnace mouth, the temperature in the furnace can be automatically and continuously measured. It can also connect external devices such as recorders, printers and large-screen displays according to user needs, automatically record the printing temperature data and change curves, as long as the measurement parameters are adjusted and set at one time, the measurement system can automatically measure and record the temperature of each furnace, providing a reliable basis for production management and process improvement.

D-T5 continuous cast molten steel thermometer is a new type of molten steel and molten iron thermometer that combines infrared induction and thermal imaging technology. The whole system is combined with a fully radiated vanadium oxide sensor (VOX) photoelectric technology, and the uncooled microthermal radiation type is used to accurately measure the temperature.

D-T5 continuous cast molten steel thermometer better resists the interference of electromagnetic, smoke and dust on site. The scanning temperature measurement eliminates the scum interference of molten steel and molten iron levels, making the measurement more stable and accurate, and the sturdy shell makes it suitable for various harsh working environments. At the same time, it can continuously monitor each furnace of molten steel or molten iron.

The methods for improving the accuracy of infrared thermometers (with the instrument fixed) can be summarized in practice as follows:

1. Regularly proofread with hot couples (for different materials and different temperature ranges, proofreading is required!) 2. Ensure that the surface of the metal liquid is cleaned during temperature measurement.

3. It is best to use it at a fixed distance from the metal liquid level!

4. I don't test a few sets of data to compare and average the average!

5. Different metals emit red infrared spectral bands differently, and the thermometer should have a selection gear, and it must be right!

The undisputed understanding of infrared technology and its principles is its precise temperature measurement. When the temperature is measured by an infrared thermometer, the infrared energy emitted by the measured object is converted into an electrical signal on the detector through the optical system of the infrared thermometer, and the temperature reading of the signal is displayed.

There are several important factors that determine accurate temperature measurement, the most important being emissivity, field of view, distance to the spot, and spot location.

First of all, choose the right infrared thermometer, if the requirements are general, casually Leitai, domestic (Xi'an, Shaanxi over there to teach more)** relatively cheap. If the process requirements are high. American love light (IRCON) ah or something, you can find out.

The key is to select, pay attention to the temperature range, distance coefficient. Select the appropriate measuring distance based on the known distance coefficient. If economic conditions allow, you can choose a colorimetric infrared thermometer. You can talk to each other.

Buy a good thermometer and measure it by the contrast method.

The United States Aiguang (IRCON) can learn about the specific application, welcome to contact.

Summary. In the fast thermoelectric Yu insertion method, although its temperature value can be recorded by the recorder, Cangzhou Oupu can only measure the temperature at the moment of insertion, and can not measure the temperature continuously for a long time, so it can only be sampled a few points in the smelting process, and the temperature change of the whole process can not be mastered, and each time the temperature measurement must be manually inserted and operated, a galvanic couple can only be used 1-2 times, and the consumption of electric Yu is larger, and the use is more troublesome.

Hello dear here, I can find an infrared thermometer for casting thermometers.

After the infrared thermometer, as long as the infrared probe is fixed at the appropriate position within ten meters from the furnace mouth, and the furnace mouth is aimed at the furnace mouth through the aim, the infrared temperature measurement chain can automatically and continuously measure the hunger of the greenhouse in the furnace, and the instrument output signal can be connected to external equipment such as recorders, printers and large screen displays, which can automatically record and print out the temperature change curve and temperature measurement time in the furnace.

The common methods for measuring the temperature of molten iron and molten steel in the foundry industry are optical pyrometer and fast thermocouple insertion method. Among them, the temperature measurement accuracy of the optical pyrometer is low, and because it has no corresponding electrical signal output, it cannot be connected to the recording equipment such as the recorder or the printer difference, and the measured temperature can only be recorded manually, and the authenticity of the recorded data cannot be guaranteed.

In the fast thermoelectric Yu insertion method, although its temperature value can be recorded by the recorder, Cangzhou Oupu can only measure the temperature bridge at the moment of insertion, and can not measure the temperature continuously for a long time, so it can only be sampled a few points in the smelting process, and the temperature change of the whole process can not be mastered, and each temperature measurement must be manually inserted and operated, a galvanic couple can only be used 1-2 times, and the desensitization of electric Yu is larger, which makes Xinchang more troublesome.

Casting is a kind of metal thermal processing technology that has been mastered by human beings for about 6,000 years. Casting is a method of pouring liquid larrow metal into a casting cavity that is suitable for the shape of the part, and waiting for it to cool and solidify to obtain a part or a wide blank.

Which infrared thermometer is more accurate and stable?

Kiss non-contact infrared thermometer.

Depends on the model chosen, the measured target and the emissivity working together. It is not possible to generalize.

1. The accuracy of the model can be reached up to the highest.

2. For different measurement targets, adjust the emissivity to the correct measurement target (such as copper, if the wavelength is 8 14 microns, adjust to the best; Infrared thermometers of different wavelengths have different emissivity for different objects and cannot be generalized).

Therefore, the accuracy of the infrared thermometer depends on whether the selection is correct and whether the emissivity adjustment is correct; It is not possible to generalize.
