Autoclave temperature calibration device and method

Abstract

The invention discloses an autoclave temperature calibration device and method. The autoclave temperature calibration device comprises a plurality of temperature measuring holes formed in an autoclavecover and a plurality of temperature measuring tubes arranged on the autoclave cover. The autoclave temperature calibration method comprises the following steps of: 1, measuring the temperature in anautoclave cavity; 2, calculating the temperature uniformity in the autoclave cavity; 3, calculating the maximum temperature difference of an axial temperature field in the autoclave cavity; 4, calculating the maximum temperature difference of a radial temperature field in the autoclave cavity; 5, calculating the temperature deviation in the autoclave cavity; 6, calculating the temperature stability in the autoclave cavity; and 7, giving a calibration report corresponding to the calibration result. The device provided by the invention is novel and reasonable in design, calibration of a radialfull-range temperature field and an axial full-range temperature field of the autoclave is achieved when the temperature sensors work in the temperature measuring tubes, temperature calibration of theautoclave is more accurate, operation is easy and convenient, and the using effect is good.

Description

technical field [0001] The invention belongs to the technical field of measurement and detection, and in particular relates to an autoclave temperature calibration device and method. Background technique [0002] The autoclave is composed of the body, the autoclave cover, the circulating fan, the heater, the cooling device, the electric control cabinet and other parts. There are three stages of temperature reduction and pressure reduction. [0003] In the non-ferrous metal industry, autoclaves are mainly used for corrosion tests, and are widely used in the nuclear industry. When testing the corrosion performance of zirconium and hafnium materials in the nuclear industry, the accuracy of the test temperature has a great influence on the test results. The autoclave is filled with high-pressure water or For high-pressure water vapor, it is necessary to confirm whether the temperature in the autoclave meets the requirements of the corrosion test under high pressure conditions. ...

AI Technical Summary

Problems solved by technology

[0004] Existing autoclave temperature calibration usually collects the temperature values ​​of five points in the autoclave cavity: front lower left, front upper right, rear upper left, rear upper right and geometric center point for calibration, but the accuracy is not high; in order to solve Under the premise of not changing the structure and operation mode of the existing autoclave cavity of the autoclave, the problem of high-precision calibration of the axial temperature field and radial temperature field of the autoclave at 300 ° C to 500 ° C under a high-pressure atmosphere requires a Autoclave temperature calibration device and method, meeting the demand for high-precision temperature calibration of autoclaves
