High temperature solid surface long term accurate temperature measuring system in complicated environment

Abstract

The invention provides a mid-high temperature solid surface long-term accurate temperature measurement system of a complex environment, comprising a non-contact type temperature measurement instrument, an incubator, a dustproof sleeve, and a swirl generator, wherein the incubator is divided into a front cavity and a rear cavity through a baffle, the temperature measurement instrument is arranged in the rear cavity, the dustproof sleeve is arranged in the front cavity; the front end of the dustproof sleeve is provided with a lens and the swirl generator, while the front end of the swirl generator is provided with a sighting tube. A probe aims at the temperature measurement surface through the dustproof sleeve, the lens and the sighting tube. The swirl generator generates a certain positive pressure at the front of the dustproof sleeve, so that the outside pollutant is prevented from approaching the dustproof sleeve and the lens, and heat ray from the surface of the measured object is directly introduced into a temperature measurement probe without being absorbed by the participatory media. The sighting tube prevents the difficulty brought by the correction of other heat radiation to the temperature of the temperature measurement instrument. The incubator and the dustproof sleeve provide a favorable working environment, so the invention can perform long-term, stable, continuous, and accurate temperature measurement in the complex environment.

Description

technical field [0001] The invention relates to a long-term temperature measurement system, in particular to a long-term and accurate measurement system for high-temperature solid surface temperature in complex environments. This temperature measurement system is mainly used in continuous production systems such as online measurement of billet surface temperature in the secondary cooling process of metal continuous casting, online temperature measurement of heating furnace, and online temperature measurement in metal rolling process. Long-term online, continuous, and accurate temperature measurement in complex environments is of great significance to improve production process control and product quality. Background technique [0002] In recent years, my country's metallurgical industry has developed very rapidly, among which, the output of iron and steel products has ranked first in the world for more than ten consecutive years. In order to further improve the quality of p...

Problems solved by technology

At the same time, in order to reduce the influence of the measurement distance on the temperature measurement results during the on-site work of the temperature measurement equipment, the distance coefficient needs to be considered in the process of temperature measurement. With the shortening of the temperature measurement distance, the temperature measurement environment of the temperature measurement instrument is more Harsh, due to working in a harsh environment, the probe is easily polluted, such as online temperature measurement in the continuous casting process, the temperature measurement distance is 300mm, the probe or the dust-proof glass in front of the probe will be polluted within 5-10 minutes However, the measured temperature readings are significantly distorted, even after certain cleaning measures are taken, it is still difficult to solve this problem, which makes how to provide a clean external environment for the thermometer in a complex environment becomes one of the biggest limiting links
