  • Light guide for transmitting thermal radiation from melt to pyrometer and method of measuring temperature of molten metal in metallurgical vessel with the aid of said light guide
    Patent number: 4533243
    Abstract: The light guide and the method of measuring temperature with the aid of said light guide relate to optical pyrometry of melts.A light guide 1 is made from a light-permeable refractory corrosion-resistant material such as leucosapphire, for example, and according to the invention comprises 2 portions: a narrow portion 2 in the form of a rod, and a large portion 3 with a flat end 3a being an operating end of the light guide 1. The large portion 3 of the light guide 1 represents with respect to the narrow portion 2 an optical cavity producing radiation of the operating end 3a substantially in the form of a radiation of an absolutely black body. The ratio of the cross-section area of the narrow portion 2 at the place where it adjoins the large portion 3 does not exceed 0.5.
