Continuous casting two cold closed chamber casting blank surface temperature field measuring device

Abstract

The invention relates a continuous casting two cold closed chamber casting blank surface temperature field measuring device. The front end of a heat insulating protective sleeve is provided with heat resisting quartz glass, and a cleaning mechanism is arranged in front of one side of the quartz glass. An infrared array CCD camera is arranged in the heat insulating protective sleeve, and a coolingsleeve is sheathed outside the heat insulating protective sleeve. An inlet gas splitter and an outlet air separator are arranged on the cooling sleeve; and the front end of the outlet air separator is provided with a guide mechanism which leads the air to horizontally blow the casting blank surface in a line shape. The device can overcome the influence of dispersed water mist medium when an optical path is measured, and lead the infrared array CCD camera to work within a controlled temperature range by a temperature sensor; the camera has strong heat resisting capabilty, and the arranged cleaning mechanism can guarantee the cleaness of the quartz class, thus being capable of realizing the measurement of the casting blank surface temperature field with long term, stability, continuity and accuracy, in the two cold closed chambers.

Description

technical field [0001] The invention relates to a temperature measuring device, in particular to a long-term and accurate measuring device for realizing the long-term and accurate temperature field of the slab surface in a closed chamber of the continuous casting secondary cooling. This temperature measuring device is mainly used in continuous production systems such as on-line measurement of the surface temperature field of the slab during the secondary cooling process of continuous casting, on-line temperature measurement of the heated billet in the heating furnace, and on-line measurement of the surface temperature field of the rolled piece during the rolling process. Long-term online, continuous and accurate temperature field measurement in complex environments such as water vapor, iron oxide scale and strong magnetic field interference is of great significance to improve the production process control level and product quality.
