Continuous casting secondary cooling strand surface temperature contact measurement device

Abstract

The present invention discloses a continuous casting secondary cooling strand surface temperature contact measurement device. The device is installed at a gap between continuous casting rollers and comprises a lifting cylinder, a cylinder connection piece, a pressing spring, a support, an anti-breaking returning node, a temperature measurement head, a roller, a strand surface, a rotation encoder, a threading and cooling air inlet, a temperature measurement rod, a temperature signal processor and a computer. Through adoption of contact measurement, the continuous casting secondary cooling strand surface temperature contact measurement device can eliminate influence of environment changing on temperature measurement, the temperature can be measured even if the strand surface has water film, water mist or oxidized scale, and the measurement precision is high; the continuous casting secondary cooling strand surface temperature contact measurement device is simple and small in structure and convenient to install, and is suitable for roller gap small casting blank surface temperature measurement; an electrical portion is separated from the temperature measurement head, the protection class reaches IP67, the environment adaptability is enhanced, and the device reliability is improved; and moreover, the anti-breaking returning node is arranged, the device fault processing capacity is improved, the damaging of the temperature measurement head is reduced, and the service life is improved.

Description

technical field [0001] The invention belongs to the field of automatic instrument measurement, in particular to a contact-type measuring device for the surface temperature of the continuous casting secondary cooling casting flow. Background technique [0002] In the closed room of continuous casting secondary cooling, the casting strand is a high-temperature moving object, and it is in the environment of high water mist, high heat radiation, dense smoke and strong magnetic field. At the same time, the surface of the casting strand is covered with irregular iron oxide scales and covered with a layer The water film makes the surface emissivity of the measured point an irregular dynamic variable. Therefore, the method of non-contact measurement using emissivity has inherent defects at the level of principle design. In addition, the measurement cost of non-contact measurement, whether it is an infrared thermometer, a CCD thermometer or a camera thermometer, is relatively high. ...
