How to detect the lining thickness of a high-temperature yemagetsi choto?

1. Capacitance nzira

Iyo capacitance nzira yakafanana neyekupikisa nzira. A coaxial circular capacitor sensor yakanyudzwa mukati mevira revira, uye kukosha kwecapacitance kunoenderana nehurefu hwayo. Ukobvu hweiyo blast furnace masonry inogona kutsanangurwa nekuyera capacitance kukosha.

2. Stress wave method

The stress wave signal is very sensitive to structural defects. When the stress wave propagates in the medium, such as holes, cracks and other interface discontinuities, reflection, refraction, scattering and mode conversion will occur. The thickness of the stave material can be determined.

3. Kuramba nzira

The resistance element is embedded inside the furnace lining, the front of the sensor is aligned with the inner surface of the furnace lining, and it is connected to the measurement system through a lead wire. The resistance value of the resistance element is related to its length. As the resistance element and the furnace lining lose synchronously, the resistance will change. Use the corresponding measurement The meter measures the electrical signal output by the component, and then the remaining thickness of the furnace lining can be measured online.

4. Nzira yekuona kupisa kwekuyerera

Zvinoenderana ne thermodynamics, mutsauko wetembiricha, thermal conductivity uye muchoto madziro ukobvu zvinotaridza kupisa kuyerera kwakanyanya. Kune blast furnace lining, iyo thermal conductivity inogadziriswa, uye huni hwemadziro ehuni hunogona kuwanikwa kubva mukusiyana kwekushisa uye kuyerera kwekushisa.

The heat flow detection sensor is installed in the lower temperature part of the furnace lining. The heat flow intensity is calculated by the water temperature difference of the cooling wall of the hearth, and the temperature value measured by the thermocouple in the brick lining is combined to calculate the thickness of the furnace wall.

5. Ultrasonic nzira

The thickness measurement is carried out at the point where the ultrasound propagates in the solid medium. At a constant temperature, the ultrasound is incident on the furnace lining and enters the furnace. The propagation time of the incident and reflection of the ultrasound in the furnace lining is used to obtain the residual thickness of the furnace lining.

6. Multi-head thermocouple nzira

Several thermocouples of different lengths are installed in a protective sleeve, and then they are installed in the brick lining that needs to be inspected, and the erosion of the masonry can be inferred by measuring the temperature change of each thermocouple. When the temperature of each point and the temperature gradient between each point are basically stable, when the brick lining is gradually eroded to a certain part, the galvanic couple in that part will be destroyed, and the temperature signal will be abnormal.

7. Muenzaniso wekufungidzira nzira

Inoshandisa thermocouples sezvinhu zvekuona, inoshandisa thermodynamics uye dzimwe dzidziso kumisikidza modhi yemasvomhu yemba uye muchoto pazasi tembiricha saiti, uye inoverengera zvinzvimbo zveyakanyungudutswa yesimbi yakanyungudutswa yekusimbisa tambo uye kabhoni zvidhinha kukukurwa kwemutsetse kuburikidza nesoftware chirongwa uye nhamba yekuongorora.
