Description

Technical Field

[0001] The utility model relates to the technical field of iron and steel metallurgy, in particular to a device for contact-type measuring the surface temperature of a continuous casting billet. Background Art

[0002] In the continuous casting production of steel metallurgy, the cooling system of the secondary cooling section directly restricts the solidification structure and quality of the ingot. Therefore, it is very important to accurately control the surface temperature of the continuous casting ingot in the secondary cooling section and optimize the secondary cooling system for the efficient and high-quality preparation of continuous casting steel ingots. However, due to the high surface temperature of the continuous casting ingot in the secondary cooling section, it is difficult for the staff to measure it for a long time; and the water mist on the surface of the ingot is relatively serious, and the surface is covered with iron oxide, which makes it extremely difficult to accurately measure the surface temperature of the continuous casting ingot.
