最近,日本NKK开发出了全新的消耗型光纤辐射温度计,并已应用于测量京浜铁所3~#连铸机中间包的钢水温度。其测量原理是将光纤前端浸入钢水中,用与光纤另一端相连的辐射温度计测量光纤前端入射的放射光。光纤的直径很细(φ50～125μm),前端与钢水形成一个透明玻璃的均热微小孔穴,成为很好的黑体,从而实现了不依赖放射率的高精确度测温。自动测温装置由与数百米光纤相连的辐射温度计、存放温度计的浇
Recently, Japan’s NKK has developed a new consumable fiber radiation thermometer, and has been used to measure the Jingbang Iron 3 ~ # caster tundish temperature of molten steel. The measuring principle is immersed in the molten steel front end of the fiber, with the other end of the fiber connected to the radiation thermometer to measure the front end of the fiber incident radiation. The diameter of the optical fiber is very small (φ50 ~ 125μm). The front end and the molten steel form a tiny hole in the soaking of the transparent glass, which becomes a very good black body, thereby achieving high-precision temperature measurement without relying on the emissivity. Automatic temperature measurement device connected by a few hundred meters with a radiation thermometer thermometer, storage thermometer pouring
